ORIGIN. "Our data show that sex chromosomes evolved from a common autosomal origin before the diversification of the extant dioecious species." https://lnkd.in/ey4vMRy View in LinkedIn

IMPORTANT QUESTION. "Understanding the driving forces and molecular processes underlying dioecy and sex chromosome evolution, leading from hermaphroditism to the occurrence of male and female individuals, is of considerable interest in fundamental and applied research." https://lnkd.in/ey4vMRy View in LinkedIn

CLUES IN NATURE. "The sexuality of flowers is an important reproductive character in angiosperms. An insight into the evolutionary events that led to the appearance of monoecious and dioecious species can be gained by comparing closely related groups with contrasting characters." https://lnkd.in/e5Q-RPV View in LinkedIn

CHROMOSOME REARRANGEMENTS. "TE insertions probably contribute to the greater degree of rearrangement of Y than X chromosomes observed in mammals and in the plants papaya and S. latifolia." (TE = transposable elements). https://lnkd.in/exrSaeb View in LinkedIn

GENETIC HOT SPOT. "The X chromosome can accumulate such female-benefit genes at a faster rate, and the ‘feminization’ of this chromosome might make it an evolutionary hot-spot for genes involved in sexual dimorphism." https://lnkd.in/ge7JD6J View in LinkedIn

X VS Y CHROMOSOMES. "TE accumulation may occur on the X as well as the Y chromosome. In dioecious plants so far studied genetically, recombination occurs in both sexes, as in mammals. The X chromosome thus has a lower recombination frequency than the autosomes, because X chromosomes recombine only in females." (TE = transposable elements). https://lnkd.in/exrSaeb View in LinkedIn

SPECIAL TRANSMISSION CASE. "Sexually dimorphic phenotypes are often associated with genes on the sex chromosomes because such genes have sex-biased transmission and genomic distributions." https://lnkd.in/ge7JD6J View in LinkedIn

BULKING SEQUENCES. "The accumulation of TEs and other repetitive sequences is probably a major contributor to the tendency for plant Y chromosomes to be larger than their X homologues." (TE = transposable elements) https://lnkd.in/exrSaeb View in LinkedIn

SPECIAL CASE. "Alleles of sex-linked genes can spread though dioecious populations even when the deleterious effects to one sex outweigh the benefits to the other." https://lnkd.in/ge7JD6J View in LinkedIn

SEX CHROMOSOMES AND TRANSPOSABLE ELEMENTS. "TE insertions may therefore accumulate in non-recombining Y chromosome regions, or the loss of gene functions in these regions (see below) may reduce selection against such insertions." (TE = transposable elements). https://lnkd.in/exrSaeb View in LinkedIn
