Dec 8, 2014 · This document discusses sex determination in plants. It covers sex determination in bryophytes, homosporous ferns, and angiosperms. For angiosperms, it outlines four main mechanisms of sex determination: 1) the active-Y system with XY sex chromosomes, 2) the X-to-autosome balance system, 3) hormonal regulation by genes, and 4) the evolution of ...
Mar 6, 2017 · Sex determination is as important for the fitness of plants as it is for animals, but its mechanisms appear to vary much more among plants than among animals, and the expression of gender in plants differs in important respects from that in most animals.
Feb 20, 2002 · Sex determination systems in plants have evolved many times from hermaphroditic ancestors (including monoecious plants with separate male and female flowers on the same individual), and...
Dec 19, 2006 · Our results make SlSTM and SlCUC strong candidates for being involved in sex determination in Silene latifolia and therefore open new perspective for molecular mechanism of sex determination in plants in general.
Mar 6, 2017 · Sex determination is as important for the fitness of plants as it is for animals, but its mechanisms appear to vary much more among plants than among animals, and the expression of gender in plants differs in important respects from that in most animals.
Jul 1, 2014 · Sex is universal amongst most eukaryotes, yet a remarkable diversity of sex determining mechanisms exists. We review our current understanding of how and why sex determination evolves in animals and plants.
Apr 1, 2021 · We review here the theoretical findings on the evolution of dioecy and sex determination in plants and also discuss recent work on the genetics of the evolution of dioecy and on the molecular characterization of the first master sex-determining genes found in plants.
Mar 21, 2022 · Key questions about the evolution and mechanistic function of sex determination and sex chromosomes in land plants, with relevant contributions in this set of articles. Collapse level
Nov 14, 2016 · The last 100 years of sex determination research in flowering plants have culminated in a new era of truly accessible genomics. As we unravel the mechanisms of sex determination across diverse sets of sex chromosomes, we must also reflect on how recent discoveries should continue to shape our models describing the evolution of young sex ...
Mar 29, 2021 · The canonical model of sex chromosome evolution in plants predicts that two sex-determining genes will become linked in a sex-determining region (SDR), followed by expanding recombination...
