Rapid Evolution of Autosomal Binding Sites of the Dosage Compensation Complex in Drosophila melanogaster and Its Association With Transcription Divergence

open access: yesFrontiers in Genetics, 2021
How pleiotropy influences evolution of protein sequence remains unclear. The male-specific lethal (MSL) complex in Drosophila mediates dosage compensation by 2-fold upregulation of the X chromosome in males.

Partial dosage compensation in Strepsiptera, a sister group of beetles. [PDF]

open access: yes, 2015
Sex chromosomes have evolved independently in many different taxa, and so have mechanisms to compensate for expression differences on sex chromosomes in males and females. Different clades have evolved vastly different ways to achieve dosage compensation,

Dosage compensation in birds [PDF]

open access: yes, 2001
The Z and W sex chromosomes of birds have evolved independently from the mammalian X and Y chromosomes [1]. Unlike mammals, female birds are heterogametic (ZW), while males are homogametic (ZZ).

Expansion of GA Dinucleotide Repeats Increases the Density of CLAMP Binding Sites on the X-Chromosome to Promote Drosophila Dosage Compensation. [PDF]

open access: yesPLoS Genetics, 2016
Dosage compensation is an essential process that equalizes transcript levels of X-linked genes between sexes by forming a domain of coordinated gene expression.

Non-canonical Drosophila X chromosome dosage compensation and repressive topologically associated domains

open access: yesEpigenetics & Chromatin, 2018
Background In animals with XY sex chromosomes, X-linked genes from a single X chromosome in males are imbalanced relative to autosomal genes. To minimize the impact of genic imbalance in male Drosophila, there is a dosage compensation complex (MSL) that ...

Compensation of Dosage-Sensitive Genes on the Chicken Z Chromosome. [PDF]

open access: yes, 2016
In many diploid species, sex determination is linked to a pair of sex chromosomes that evolved from a pair of autosomes. In these organisms, the degeneration of the sex-limited Y or W chromosome causes a reduction in gene dose in the heterogametic sex ...

X-to-autosome expression and msl-2 transcript abundance correlate among Drosophila melanogaster somatic tissues [PDF]

open access: yesPeerJ, 2015
In Drosophila melanogaster, the male-specific lethal (MSL) complex has been studied extensively for its role in upregulating male X-linked genes. Recent advances in high-throughput technologies have improved our understanding of how the MSL complex ...

Incomplete sex chromosome dosage compensation in the Indian meal moth, Plodia interpunctella, based on de novo transcriptome assembly. [PDF]

open access: yes, 2016
Journal ArticleResearch Support, Non-U.S. Gov'tMales and females experience differences in gene dose for loci in the nonrecombining region of heteromorphic sex chromosomes. If not compensated, this leads to expression imbalances, with the homogametic sex

Dosage compensation: X-repress yourself [PDF]

open access: yes, 1997
Dosage compensation in Caenorhabditis elegans involves the sex-specific recruitment to the X chromosome of a protein complex, the nature of which suggests that there are mechanistic links between chromosome segregation and global transcriptional ...

Single-cell RNA-sequencing reveals pre-meiotic X-chromosome dosage compensation in Drosophila testis.

open access: yesPLoS Genetics, 2021
Dosage compensation equalizes X-linked expression between XY males and XX females. In male fruit flies, expression levels of the X-chromosome are increased approximately two-fold to compensate for their single X chromosome. In testis, dosage compensation
