The order Verongida, considered to be exclusively oviparous and dioecious, exhibits great range in body form, including thin-bodied, rope- and stick-form members which have been postulated to be morphologically adapted to exploit fragmentation as an important asexual reproductive process. Here we ...
Phytochromes are important in allowing plants to sense and react to environmental changes. We investigated the similarities and differences of sexual and asexual offspring of a tropical liverwort (Marchantia inflexa). We expected that both types of dispersing offspring will have similar germination respon...
Apomixis in the angiosperms comprises different kinds of asexual reproduction, wholly or partly replacing the sexual cycle. Recent views on evolutionary ad... SVEN,ASKER - 《Hereditas》 被引量: 198发表: 1979年 Cytology of Some Apomictic Paspalum Species Paspalum almum Chase had a chromosome number...
Megasporogenesis in the heterosporous fern Marsilea (Hydropterideae) shows features intermediate between sporogenesis in homosporous ferns and that in heterosporous seed plants. The plastids in the dyads and young spores were associated with tubules 30-35 nm in diameter, probably a specialized form...
Evolution of Aquatic Angiosperm Reproductive Systems What is the balance between sexual and asexual reproduction in aquatic angiosperms? 来自 Semantic Scholar 喜欢 0 阅读量: 1 作者:C Philbrick,D Les 摘要: The transition to an aquatic life has been achieved by only 2% of the approximately 350,000...
commensalis is a protandrous hermaphrodite that exhibits non-seasonal sexual reproduction only. In the present study, allozyme electrophoresis was used to examine the prevalence and genetic consequences of asexual reproduction in a population of Amphianthus inornata from 2200m in the Rockall Trough, ...
Suppression ofFgVAC1led to inhibited vegetative growth, reduced asexual and sexual reproduction, decreased deoxynivalenol (DON) biosynthesis, and diminished pathogenicity. Our findings highlight the significant role of FgVac1 in vacuolar protein sorting, fungal development, and plant infection inF. ...
