Revisiting ancestral polyploidy in plants
Whole-genome duplications (WGDs) or polyploidy events have been studied extensively in plants. In a now widely cited paper, Jiao et al. presented evidence for two ancient, ancestral plant WGDs predating the origin of flowering and seed plants, respectively. This finding was based primarily on a bimodal age distribution of gene duplication events obtained from molecular dating of almost 800 phyl...
متن کاملSex Determination in Monoecious and Dioecious Plants.
Angiosperm species that produce unisexual flowers present the opportunity for separate analysis of the male and female programs for floral differentiation and gametogenesis. A vast literature describes the genetic and physiological basis of sex determination in these species. (For reviews, see Westergaard, 1958; Grant, 1975; Frankel and Galun, 1977; Durand and Durand, 1984.) Recently, it has be...
متن کاملPolyploidy and genome evolution in plants.
Genome doubling (polyploidy) has been and continues to be a pervasive force in plant evolution. Modern plant genomes harbor evidence of multiple rounds of past polyploidization events, often followed by massive silencing and elimination of duplicated genes. Recent studies have refined our inferences of the number and timing of polyploidy events and the impact of these events on genome structure...
متن کاملMethods of Sex Determination in Dioecious Angiospermous Plants
Angiosperms are the most diverse group of land plants which provides fruits, food, seed for cultivation and material for hybridization purpose etc. Approximately 90% of all angiosperm species have hermaphrodite (bisexual) flowers and the remaining, onetenth are either monoecious (male and female flowers are separate but grow in same plant) or dioecious (male and female flower grow on different ...
متن کاملDPTEdb, an integrative database of transposable elements in dioecious plants
Dioecious plants usually harbor 'young' sex chromosomes, providing an opportunity to study the early stages of sex chromosome evolution. Transposable elements (TEs) are mobile DNA elements frequently found in plants and are suggested to play important roles in plant sex chromosome evolution. The genomes of several dioecious plants have been sequenced, offering an opportunity to annotate and min...
