text: Earlier, we demonstrated that transcript levels of METAL TOLERANCE PROTEIN2
(MTP2) and of HEAVY METAL ATPase2 (HMA2) increase strongly in roots of Arabidopsis
upon prolonged zinc (Zn) deficiency and respond to shoot physiological Zn status,
and not to the local Zn status in roots. This provided evidence for shoot-to-root
communication in the acclimation of plants to Zn deficiency. Zn-deficient soils
limit both the yield and quality of agricultural crops and can result in clinically
relevant nutritional Zn deficiency in human populations. Implementing Zn deficiency
during cultivation of the model plant Arabidopsis thaliana on agar-solidified
media is difficult because trace element contaminations are present in almost
all commercially available agars. Here, we demonstrate root morphological acclimations
to Zn deficiency on agar-solidified medium following the effective removal of
contaminants. These advancements allow reproducible phenotyping toward understanding
fundamental plant responses to deficiencies of Zn and other essential trace elements.

text: Previously, we reported that the allelic de-etiolated by zinc (dez) and trichome
birefringence (tbr) mutants exhibit photomorphogenic development in the dark,
which is enhanced by high Zn. TRICHOME BIREFRINGENCE-LIKE proteins had been implicated
in transferring acetyl groups to various hemicelluloses. Pectin O-acetylation
levels were lower in dark-grown dez seedlings than in the wild type. We observed
Zn-enhanced photomorphogenesis in the dark also in the reduced wall acetylation
2 (rwa2-3) mutant, which exhibits lowered O-acetylation levels of cell wall macromolecules
including pectins and xyloglucans, supporting a role for cell wall macromolecule
O-acetylation in the photomorphogenic phenotypes of rwa2-3 and dez. Application
of very short oligogalacturonides (vsOGs) restored skotomorphogenesis in dark-grown
dez and rwa2-3. Here we demonstrate that in dez, O-acetylation of non-pectin cell
wall components, notably of xyloglucan, is enhanced. Our results highlight the
complexity of cell wall homeostasis and indicate against an influence of xyloglucan
O-acetylation on light-dependent seedling development.
