In the fruit fly Drosophila melanogaster , male-specific splicing and translation of Fruitless transcription factor (Fru M ) alters presence, anatomy, and/or connectivity >60 types central brain neurons that interconnect to generate male-typical behaviors. While indispensable function Fru in sex-specific behavior has been understood for decades, molecular mechanisms underlying its activity r...

We present a genome assembly from an individual male Lysandra coridon (the Chalkhill Blue; Arthropoda; Insecta; Lepidoptera; Lycaenidae). The sequence is 541 megabases in span. Most of the scaffolded into 90 chromosomal pseudomolecules, including assembled Z sex chromosome. mitochondrial has also been and 15.4 kilobases length. Gene annotation this on Ensembl ide...

We present a genome assembly from an individual male Zeuzera pyrina (the Leopard Moth, Arthropoda; Insecta; Lepidoptera; Cossidae). The sequence is 687 megabases in span. Most of the scaffolded into 31 chromosomal pseudomolecules, including assembled Z sex chromosome. mitochondrial has also been and 15.3 kilobases length. Gene annotation this on Ensembl identifie...

We present a genome assembly from an individual male Sarcophaga subvicina (the lesser worm flesh fly; Arthropoda; Insecta; Diptera; Sarcophagidae). The sequence is 71 megabases in span. Most of the (95.91%) scaffolded into six chromosomal pseudomolecules, with X sex chromosome assembled. mitochondrial has also been assembled and 16.7 kilobases length. Gene annota...

A fundamental problem in genome biology is to elucidate the evolutionary forces responsible for generating nonrandom patterns of genome organization. As the first metazoan to benefit from full-genome sequencing, Caenorhabditis elegans has been at the forefront of research in this area. Studies of genomic patterns, and their evolutionary underpinnings, continue to be augmented by the recent push...

The bay scallop (Argopecten irradians irradians Lamarck 1819) has become one of the most important aquaculture species in China. Genetic improvement of cultured bay scallop can bene¢t greatly from a better understanding of its genome. In this study, we developed ampli¢ed fragment length polymorphisms (AFLPs) and simple sequence repeat markers from expressed sequence tags (EST-SSRs) for linkage ...

Doubly uniparental inheritance of mitochondria (DUI) is best known in the blue mussel Mytilus. Under this model, two types of mitochondrial DNA exist: female type (F), transmitted from females to offspring of both genders, and male type (M), transmitted exclusively from males to sons. The mitogenomes are usually highly divergent, but an occasional replacement of a typical M genome by a particul...

The preservation of a homomorphic sex-determining chromosome in some organisms without transformation into a heteromorphic sex chromosome is a long-standing enigma in evolutionary biology. A dominant sex-determining locus (or M-locus) in an undifferentiated homomorphic chromosome confers the male phenotype in the yellow fever mosquito Aedes aegypti. Genetic evidence suggests that the M-locus is...
