text: Advanced transcriptome sequencing has revealed that the majority of eukaryotic
genes undergo alternative splicing (AS). Nonetheless, little effort has been dedicated
to investigating the functional relevance of particular splicing events, even
those in the key developmental and hormonal regulators. Combining approaches of
genetics, biochemistry and advanced confocal microscopy, we describe the impact
of alternative splicing on the PIN7 gene in the model plant Arabidopsis thaliana.
PIN7 encodes a polarly localized transporter for the phytohormone auxin and produces
two evolutionarily conserved transcripts, PIN7a and PIN7b. PIN7a and PIN7b, differing
in a four amino acid stretch, exhibit almost identical expression patterns and
subcellular localization. We reveal that they are closely associated and mutually
influence each other's mobility within the plasma membrane. Phenotypic complementation
tests indicate that the functional contribution of PIN7b per se is minor, but
it markedly reduces the prominent PIN7a activity, which is required for correct
seedling apical hook formation and auxin-mediated tropic responses. Our results
establish alternative splicing of the PIN family as a conserved, functionally
relevant mechanism, revealing an additional regulatory level of auxin-mediated
plant development.

text: Small RNAs (smRNA, 19–25 nucleotides long), which are transcribed by RNA polymerase
II, regulate the expression of genes involved in a multitude of processes in eukaryotes.
miRNA biogenesis and the proteins involved in the biogenesis pathway differ across
plant and animal lineages. The major proteins constituting the biogenesis pathway,
namely, the Dicers (DCL/DCR) and Argonautes (AGOs), have been extensively studied.
However, the accessory proteins (DAWDLE (DDL), SERRATE (SE), and TOUGH (TGH))
of the pathway that differs across the two lineages remain largely uncharacterized.
We present the first detailed report on the molecular evolution and divergence
of these proteins across eukaryotes. Although DDL is present in eukaryotes and
prokaryotes, SE and TGH appear to be specific to eukaryotes. The addition/deletion
of specific domains and/or domain-specific sequence divergence in the three proteins
points to the observed functional divergence of these proteins across the two
lineages, which correlates with the differences in miRNA length across the two
lineages. Our data enhance the current understanding of the structure–function
relationship of these proteins and reveals previous unexplored crucial residues
in the three proteins that can be used as a basis for further functional characterization.
The data presented here on the number of miRNAs in crown eukaryotic lineages are
consistent with the notion of the expansion of the number of miRNA-coding genes
in animal and plant lineages correlating with organismal complexity. Whether this
difference in functionally correlates with the diversification (or presence/absence)
of the three proteins studied here or the miRNA signaling in the plant and animal
lineages is unclear. Based on our results of the three proteins studied here and
previously available data concerning the evolution of miRNA genes in the plant
and animal lineages, we believe that miRNAs probably evolved once in the ancestor
to crown eukaryotes and have diversified independently in the eukaryotes.

text: 'AtNHX5 and AtNHX6 are endosomal Na+,K+/H+ antiporters that are critical for
growth and development in Arabidopsis, but the mechanism behind their action remains
unknown. Here, we report that AtNHX5 and AtNHX6, functioning as H+ leak, control
auxin homeostasis and auxin-mediated development. We found that nhx5 nhx6 exhibited
growth variations of auxin-related defects. We further showed that nhx5 nhx6 was
affected in auxin homeostasis. Genetic analysis showed that AtNHX5 and AtNHX6
were required for the function of the ER-localized auxin transporter PIN5. Although
AtNHX5 and AtNHX6 were co-localized with PIN5 at ER, they did not interact directly.
Instead, the conserved acidic residues in AtNHX5 and AtNHX6, which are essential
for exchange activity, were required for PIN5 function. AtNHX5 and AtNHX6 regulated
the pH in ER. Overall, AtNHX5 and AtNHX6 may regulate auxin transport across the
ER via the pH gradient created by their transport activity. H+-leak pathway provides
a fine-tuning mechanism that controls cellular auxin fluxes. '

text: Plant development mediated by the phytohormone auxin depends on tightly controlled
cellular auxin levels at its target tissue that are largely established by intercellular
and intracellular auxin transport mediated by PIN auxin transporters. Among the
eight members of the Arabidopsis PIN family, PIN6 is the least characterized candidate.
In this study we generated functional, fluorescent protein-tagged PIN6 proteins
and performed comprehensive analysis of their subcellular localization and also
performed a detailed functional characterization of PIN6 and its developmental
roles. The localization study of PIN6 revealed a dual localization at the plasma
membrane (PM) and endoplasmic reticulum (ER). Transport and metabolic profiling
assays in cultured cells and Arabidopsis strongly suggest that PIN6 mediates both
auxin transport across the PM and intracellular auxin homeostasis, including the
regulation of free auxin and auxin conjugates levels. As evidenced by the loss-
and gain-of-function analysis, the complex function of PIN6 in auxin transport
and homeostasis is required for auxin distribution during lateral and adventitious
root organogenesis and for progression of these developmental processes. These
results illustrate a unique position of PIN6 within the family of PIN auxin transporters
and further add complexity to the developmentally crucial process of auxin transport.

text: Strigolactones, first discovered as germination stimulants for parasitic weeds
[1], are carotenoid-derived phytohormones that play major roles in inhibiting
lateral bud outgrowth and promoting plant-mycorrhizal symbiosis [2-4]. Furthermore,
strigolactones are involved in the regulation of lateral and adventitious root
development, root cell division [5, 6], secondary growth [7], and leaf senescence
[8]. Recently, we discovered the strigolactone transporter Petunia axillaris PLEIOTROPIC
DRUG RESISTANCE 1 (PaPDR1), which is required for efficient mycorrhizal colonization
and inhibition of lateral bud outgrowth [9]. However, how strigolactones are transported
through the plant remained unknown. Here we show that PaPDR1 exhibits a cell-type-specific
asymmetric localization in different root tissues. In root tips, PaPDR1 is co-expressed
with the strigolactone biosynthetic gene DAD1 (CCD8), and it is localized at the
apical membrane of root hypodermal cells, presumably mediating the shootward transport
of strigolactone. Above the root tip, in the hypodermal passage cells that form
gates for the entry of mycorrhizal fungi, PaPDR1 is present in the outer-lateral
membrane, compatible with its postulated function as strigolactone exporter from
root to soil. Transport studies are in line with our localization studies since
(1) a papdr1 mutant displays impaired transport of strigolactones out of the root
tip to the shoot as well as into the rhizosphere and (2) DAD1 expression and PIN1/PIN2
levels change in plants deregulated for PDR1 expression, suggestive of variations
in endogenous strigolactone contents. In conclusion, our results indicate that
the polar localizations of PaPDR1 mediate directional shootward strigolactone
transport as well as localized exudation into the soil.

text: The plant hormone auxin is a key regulator of plant growth and development.
Auxin levels are sensed and interpreted by distinct receptor systems that activate
a broad range of cellular responses. The Auxin-Binding Protein1 (ABP1) that has
been identified based on its ability to bind auxin with high affinity is a prime
candidate for the extracellular receptor responsible for mediating a range of
auxin effects, in particular, the fast non-transcriptional ones. Contradictory
genetic studies suggested prominent or no importance of ABP1 in many developmental
processes. However, how crucial the role of auxin binding to ABP1 is for its functions
has not been addressed. Here, we show that the auxin-binding pocket of ABP1 is
essential for its gain-of-function cellular and developmental roles. In total,
16 different abp1 mutants were prepared that possessed substitutions in the metal
core or in the hydrophobic amino acids of the auxin-binding pocket as well as
neutral mutations. Their analysis revealed that an intact auxin-binding pocket
is a prerequisite for ABP1 to activate downstream components of the ABP1 signalling
pathway, such as Rho of Plants (ROPs) and to mediate the clathrin association
with membranes for endocytosis regulation. In planta analyses demonstrated the
importance of the auxin binding pocket for all known ABP1-mediated postembryonic
developmental processes, including morphology of leaf epidermal cells, root growth
and root meristem activity, and vascular tissue differentiation. Taken together,
these findings suggest that auxin binding to ABP1 is central to its function,
supporting the role of ABP1 as auxin receptor.

text: 'Exogenous application of biologically important molecules for plant growth
promotion and/or regulation is very common both in plant research and horticulture.
Plant hormones such as auxins and cytokinins are classes of compounds which are
often applied exogenously. Nevertheless, plants possess a well-established machinery
to regulate the active pool of exogenously applied compounds by converting them
to metabolites and conjugates. Consequently, it is often very useful to know the
in vivo status of applied compounds to connect them with some of the regulatory
events in plant developmental processes. The in vivo status of applied compounds
can be measured by incubating plants with radiolabeled compounds, followed by
extraction, purification, and HPLC metabolic profiling of plant extracts. Recently
we have used this method to characterize the intracellularly localized PIN protein,
PIN5. Here we explain the method in detail, with a focus on general application. '

text: The mode of action of auxin is based on its non-uniform distribution within
tissues and organs. Despite the wide use of several auxin analogues in research
and agriculture, little is known about the specificity of different auxin-related
transport and signalling processes towards these compounds. Using seedlings of
Arabidopsis thaliana and suspension-cultured cells of Nicotiana tabacum (BY-2),
the physiological activity of several auxin analogues was investigated, together
with their capacity to induce auxin-dependent gene expression, to inhibit endocytosis
and to be transported across the plasma membrane. This study shows that the specificity
criteria for different auxin-related processes vary widely. Notably, the special
behaviour of some synthetic auxin analogues suggests that they might be useful
tools in investigations of the molecular mechanism of auxin action. Thus, due
to their differential stimulatory effects on DR5 expression, indole-3-propionic
(IPA) and 2,4,5-trichlorophenoxy acetic (2,4,5-T) acids can serve in studies of
TRANSPORT INHIBITOR RESPONSE 1/AUXIN SIGNALLING F-BOX (TIR1/AFB)-mediated auxin
signalling, and 5-fluoroindole-3-acetic acid (5-F-IAA) can help to discriminate
between transcriptional and non-transcriptional pathways of auxin signalling.
The results demonstrate that the major determinants for the auxin-like physiological
potential of a particular compound are very complex and involve its chemical and
metabolic stability, its ability to distribute in tissues in a polar manner and
its activity towards auxin signalling machinery.

text: Plant-specific PIN-formed (PIN) efflux transporters for the plant hormone
auxin are required for tissue-specific directional auxin transport and cellular
auxin homeostasis. The Arabidopsis PIN protein family has been shown to play important
roles in developmental processes such as embryogenesis, organogenesis, vascular
tissue differentiation, root meristem patterning and tropic growth. Here we analyzed
roles of the less characterised Arabidopsis PIN6 auxin transporter. PIN6 is auxin-inducible
and is expressed during multiple auxin-regulated developmental processes. Loss
of pin6 function interfered with primary root growth and lateral root development.
Misexpression of PIN6 affected auxin transport and interfered with auxin homeostasis
in other growth processes such as shoot apical dominance, lateral root primordia
development, adventitious root formation, root hair outgrowth and root waving.
These changes in auxin-regulated growth correlated with a reduction in total auxin
transport as well as with an altered activity of DR5-GUS auxin response reporter.
Overall, the data indicate that PIN6 regulates auxin homeostasis during plant
development.

text: 'Clathrin-mediated endocytosis (CME) regulates many aspects of plant development,
including hormone signaling and responses to environmental stresses. Despite the
importance of this process, the machinery that regulates CME in plants is largely
unknown. In mammals, the heterotetrameric ADAPTOR PROTEIN COMPLEX-2 (AP-2) is
required for the formation of clathrin-coated vesicles at the plasma membrane
(PM). Although the existence of AP-2 has been predicted in Arabidopsis thaliana,
the biochemistry and functionality of the complex is still uncharacterized. Here,
we identified all the subunits of the Arabidopsis AP-2 by tandem affinity purification
and found that one of the large AP-2 subunits, AP2A1, localized at the PM and
interacted with clathrin. Furthermore, endocytosis of the leucine-rich repeat
receptor kinase, BRASSINOSTEROID INSENSITIVE1 (BRI1), was shown to depend on AP-2.
Knockdown of the two Arabidopsis AP2A genes or overexpression of a dominant-negative
version of the medium AP-2 subunit, AP2M, impaired BRI1 endocytosis and enhanced
the brassinosteroid signaling. Our data reveal that the CME machinery in Arabidopsis
is evolutionarily conserved and that AP-2 functions in receptormediated endocytosis. '

text: The native auxin, indole-3-acetic acid (IAA), is a major regulator of plant
growth and development. Its nonuniform distribution between cells and tissues
underlies the spatiotemporal coordination of many developmental events and responses
to environmental stimuli. The regulation of auxin gradients and the formation
of auxin maxima/minima most likely involve the regulation of both metabolic and
transport processes. In this article, we have demonstrated that 2-oxindole-3-acetic
acid (oxIAA) is a major primary IAA catabolite formed in Arabidopsis thaliana
root tissues. OxIAA had little biological activity and was formed rapidly and
irreversibly in response to increases in auxin levels. We further showed that
there is cell type-specific regulation of oxIAA levels in the Arabidopsis root
apex. We propose that oxIAA is an important element in the regulation of output
from auxin gradients and, therefore, in the regulation of auxin homeostasis and
response mechanisms.

text: Auxin is a key coordinative signal required for many aspects of plant development
and its levels are controlled by auxin metabolism and intercellular auxin transport.
Here we find that a member of PIN auxin transporter family, PIN8 is expressed
in male gametophyte of Arabidopsis thaliana and has a crucial role in pollen development
and functionality. Ectopic expression in sporophytic tissues establishes a role
of PIN8 in regulating auxin homoeostasis and metabolism. PIN8 co-localizes with
PIN5 to the endoplasmic reticulum (ER) where it acts as an auxin transporter.
Genetic analyses reveal an antagonistic action of PIN5 and PIN8 in the regulation
of intracellular auxin homoeostasis and gametophyte as well as sporophyte development.
Our results reveal a role of the auxin transport in male gametophyte development
in which the distinct actions of ER-localized PIN transporters regulate cellular
auxin homoeostasis and maintain the auxin levels optimal for pollen development
and pollen tube growth.

text: Remarkable progress in various techniques of in vivo fluorescence microscopy
has brought an urgent need for reliable markers for tracking cellular structures
and processes. The goal of this manuscript is to describe unexplored effects of
the FM (Fei Mao) styryl dyes, which are widely used probes that label processes
of endocytosis and vesicle trafficking in eukaryotic cells. Although there are
few reports on the effect of styryl dyes on membrane fluidity and the activity
of mammalian receptors, FM dyes have been considered as reliable tools for tracking
of plant endocytosis. Using plasma membrane-localized transporters for the plant
hormone auxin in tobacco BY-2 and Arabidopsis thaliana cell suspensions, we show
that routinely used concentrations of FM 4-64 and FM 5-95 trigger transient re-localization
of these proteins, and FM 1-43 affects their activity. The active process of re-localization
is blocked neither by inhibitors of endocytosis nor by cytoskeletal drugs. It
does not occur in A. thaliana roots and depends on the degree of hydrophobicity
(lipophilicity) of a particular FM dye. Our results emphasize the need for circumspection
during in vivo studies of membrane proteins performed using simultaneous labelling
with FM dyes.

Spatial distribution of the plant hormone auxin regulates multiple aspects of plant development. These self-regulating auxin gradients are established by the action of PIN auxin transporters, whose activity is regulated by their constitutive cycling between the plasma membrane and endosomes. Here, we show that auxin signaling by the auxin receptor AUXIN-BINDING PROTEIN 1 (ABP1) inhibits the clathrin-mediated internalization of PIN proteins. ABP1 acts as a positive factor in clathrin recruitment to the plasma membrane, thereby promoting endocytosis. Auxin binding to ABP1 interferes with this action and leads to the inhibition of clathrin-mediated endocytosis. Our study demonstrates that ABP1 mediates a nontranscriptional auxin signaling that regulates the evolutionarily conserved process of clathrin-mediated endocytosis and suggests that this signaling may be essential for the developmentally important feedback of auxin on its own transport.

text: 'Plant development is governed by signaling molecules called phytohormones.
Typically, in certain developmental processes more than 1 hormone is implicated
and, thus, coordination of their overlapping activities is crucial for correct
plant development. However, molecular mechanisms underlying the hormonal crosstalk
are only poorly understood. Multiple hormones including cytokinin and auxin have
been implicated in the regulation of root development. Here we dissect the roles
of cytokinin in modulating growth of the primary root. We show that cytokinin
effect on root elongation occurs through ethylene signaling whereas cytokinin
effect on the root meristem size involves ethylene-independent modulation of transport-dependent
asymmetric auxin distribution. Exogenous or endogenous modification of cytokinin
levels and cytokinin signaling lead to specific changes in transcription of several
auxin efflux carrier genes from the PIN family having a direct impact on auxin
efflux from cultured cells and on auxin distribution in the root apex. We propose
a novel model for cytokinin action in regulating root growth: Cytokinin influences
cell-to-cell auxin transport by modification of expression of several auxin transport
components and thus modulates auxin distribution important for regulation of activity
and size of the root meristem.'
