text: Since the commercialization of brine shrimp (genus Artemia) in the 1950s,
this lineage, and in particular the model species Artemia franciscana, has been
the subject of extensive research. However, our understanding of the genetic mechanisms
underlying various aspects of their reproductive biology, including sex determination,
is still lacking. This is partly due to the scarcity of genomic resources for
Artemia species and crustaceans in general. Here, we present a chromosome-level
genome assembly of A. franciscana (Kellogg 1906), from the Great Salt Lake, United
States. The genome is 1 GB, and the majority of the genome (81%) is scaffolded
into 21 linkage groups using a previously published high-density linkage map.
We performed coverage and FST analyses using male and female genomic and transcriptomic
reads to quantify the extent of differentiation between the Z and W chromosomes.
Additionally, we quantified the expression levels in male and female heads and
gonads and found further evidence for dosage compensation in this species.

text: 'Many insects carry an ancient X chromosome - the Drosophila Muller element
F - that likely predates their origin. Interestingly, the X has undergone turnover
in multiple fly species (Diptera) after being conserved for more than 450 MY.
The long evolutionary distance between Diptera and other sequenced insect clades
makes it difficult to infer what could have contributed to this sudden increase
in rate of turnover. Here, we produce the first genome and transcriptome of a
long overlooked sister-order to Diptera: Mecoptera. We compare the scorpionfly
Panorpa cognata X-chromosome gene content, expression, and structure, to that
of several dipteran species as well as more distantly-related insect orders (Orthoptera
and Blattodea). We find high conservation of gene content between the mecopteran
X and the dipteran Muller F element, as well as several shared biological features,
such as the presence of dosage compensation and a low amount of genetic diversity,
consistent with a low recombination rate. However, the two homologous X chromosomes
differ strikingly in their size and number of genes they carry. Our results therefore
support a common ancestry of the mecopteran and ancestral dipteran X chromosomes,
and suggest that Muller element F shrank in size and gene content after the split
of Diptera and Mecoptera, which may have contributed to its turnover in dipteran
insects.'

text: "The regulatory architecture of gene expression is known to differ substantially
between sexes in Drosophila, but most studies performed\r\nso far used whole-body
data and only single crosses, which may have limited their scope to detect patterns
that are robust across tissues\r\nand biological replicates. Here, we use allele-specific
gene expression of parental and reciprocal hybrid crosses between 6 Drosophila\r\nmelanogaster
inbred lines to quantify cis- and trans-regulatory variation in heads and gonads
of both sexes separately across 3 replicate\r\ncrosses. Our results suggest that
female and male heads, as well as ovaries, have a similar regulatory architecture.
On the other hand,\r\ntestes display more and substantially different cis-regulatory
effects, suggesting that sex differences in the regulatory architecture that\r\nhave
been previously observed may largely derive from testis-specific effects. We also
examine the difference in cis-regulatory variation\r\nof genes across different
levels of sex bias in gonads and heads. Consistent with the idea that intersex
correlations constrain expression\r\nand can lead to sexual antagonism, we find
more cis variation in unbiased and moderately biased genes in heads. In ovaries,
reduced cis\r\nvariation is observed for male-biased genes, suggesting that cis
variants acting on these genes in males do not lead to changes in ovary\r\nexpression.
Finally, we examine the dominance patterns of gene expression and find that sex-
and tissue-specific patterns of inheritance\r\nas well as trans-regulatory variation
are highly variable across biological crosses, although these were performed in
highly controlled\r\nexperimental conditions. This highlights the importance of
using various genetic backgrounds to infer generalizable patterns."

text: Eurasian brine shrimp (genus Artemia) have closely related sexual and asexual
lineages of parthenogenetic females, which produce rare males at low frequencies.
Although they are known to have ZW chromosomes, these are not well characterized,
and it is unclear whether they are shared across the clade. Furthermore, the underlying
genetic architecture of the transmission of asexuality, which can occur when rare
males mate with closely related sexual females, is not well understood. We produced
a chromosome-level assembly for the sexual Eurasian species Artemia sinica and
characterized in detail the pair of sex chromosomes of this species. We combined
this new assembly with short-read genomic data for the sexual species Artemia
sp. Kazakhstan and several asexual lineages of Artemia parthenogenetica, allowing
us to perform an in-depth characterization of sex-chromosome evolution across
the genus. We identified a small differentiated region of the ZW pair that is
shared by all sexual and asexual lineages, supporting the shared ancestry of the
sex chromosomes. We also inferred that recombination suppression has spread to
larger sections of the chromosome independently in the American and Eurasian lineages.
Finally, we took advantage of a rare male, which we backcrossed to sexual females,
to explore the genetic basis of asexuality. Our results suggest that parthenogenesis
is likely partly controlled by a locus on the Z chromosome, highlighting the interplay
between sex determination and asexuality.

text: While sexual reproduction is widespread among many taxa, asexual lineages
have repeatedly evolved from sexual ancestors. Despite extensive research on the
evolution of sex, it is still unclear whether this switch represents a major transition
requiring major molecular reorganization, and how convergent the changes involved
are. In this study, we investigated the phylogenetic relationship and patterns
of gene expression of sexual and asexual lineages of Eurasian Artemia brine shrimp,
to assess how gene expression patterns are affected by the transition to asexuality.
We find only a few genes that are consistently associated with the evolution of
asexuality, suggesting that this shift may not require an extensive overhauling
of the meiotic machinery. While genes with sex-biased expression have high rates
of expression divergence within Eurasian Artemia, neither female- nor male-biased
genes appear to show unusual evolutionary patterns after sexuality is lost, contrary
to theoretical expectations.

text: Males and females of Artemia franciscana, a crustacean commonly used in the
aquarium trade, are highly dimorphic. Sex is determined by a pair of ZW chromosomes,
but the nature and extent of differentiation of these chromosomes is unknown.
Here, we characterize the Z chromosome by detecting genomic regions that show
lower genomic coverage in female than in male samples, and regions that harbor
an excess of female-specific SNPs. We detect many Z-specific genes, which no longer
have homologs on the W, but also Z-linked genes that appear to have diverged very
recently from their existing W-linked homolog. We assess patterns of male and
female expression in two tissues with extensive morphological dimorphism, gonads,
and heads. In agreement with their morphology, sex-biased expression is common
in both tissues. Interestingly, the Z chromosome is not enriched for sex-biased
genes, and seems to in fact have a mechanism of dosage compensation that leads
to equal expression in males and in females. Both of these patterns are contrary
to most ZW systems studied so far, making A. franciscana an excellent model for
investigating the interplay between the evolution of sexual dimorphism and dosage
compensation, as well as Z chromosome evolution in general.

text: While chromosome-wide dosage compensation of the X chromosome has been found
in many species, studies in ZW clades have indicated that compensation of the
Z is more localized and/or incomplete. In the ZW Lepidoptera, some species show
complete compensation of the Z chromosome, while others lack full equalization,
but what drives these inconsistencies is unclear. Here, we compare patterns of
male and female gene expression on the Z chromosome of two closely related butterfly
species, Papilio xuthus and Papilio machaon, and in multiple tissues of two moths
species, Plodia interpunctella and Bombyx mori, which were previously found to
differ in the extent to which they equalize Z-linked gene expression between the
sexes. We find that, while some species and tissues seem to have incomplete dosage
compensation, this is in fact due to the accumulation of male-biased genes and
the depletion of female-biased genes on the Z chromosome. Once this is accounted
for, the Z chromosome is fully compensated in all four species, through the up-regulation
of Z expression in females and in some cases additional down-regulation in males.
We further find that both sex-biased genes and Z-linked genes have increased rates
of expression divergence in this clade, and that this can lead to fast shifts
in patterns of gene expression even between closely related species. Taken together,
these results show that the uneven distribution of sex-biased genes on sex chromosomes
can confound conclusions about dosage compensation and that Z chromosome-wide
dosage compensation is not only possible but ubiquitous among Lepidoptera.
