The Plant Cell, 2002 In a letter addressed to Joseph Hooker in 1879, Charles Darwin referred to the rapid development and diversification of the flowering plants in recent geological times as an “abominable mystery.” The mystery of the origin of angiosperms, the development of floral characters, and the ...

Variation in plastid genomes in the gynodioecious species Silene vulgaris
BMC Plant Biology, 2019 Background Gynodioecious species exist in two sexes – male-sterile females and hermaphrodites. Male sterility in higher plants often results from mitonuclear interaction between the CMS (cytoplasmic male sterility) gene(s) encoded by mitochondrial genome

Recent advances in understanding of meiosis initiation and the apomictic pathway in plants
Frontiers in Plant Science, 2014 Meiosis, a specialized cell division to produce haploid cells, marks the transition from a sporophytic to a gametophytic generation in the life cycle of plants.

Acta Societatis Botanicorum Poloniae, 2019 Floral nectar is one of the key rewards in the mutualistic interactions between plants and pollinators. However, there is a growing amount of evidence that shows that another group of organisms may be involved in the pollination process, namely the ...

Protein Farnesylation Takes Part in Arabidopsis Seed Development
Frontiers in Plant Science, 2021 Protein farnesylation is a post-translational modification regulated by the ERA1 (Enhanced Response to ABA 1) gene encoding the β-subunit of the protein farnesyltransferase in Arabidopsis.

Understanding plant reproductive diversity [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2010 Flowering plants display spectacular floral diversity and a bewildering array of reproductive adaptations that promote mating, particularly outbreeding. A striking feature of this diversity is that related species often differ in pollination and mating systems, and intraspecific variation in sexual traits is not unusual, especially among herbaceous ...

Frontiers in Plant Science, 2021 The global climate change is leading to increased frequency of heatwaves with crops getting exposed to extreme temperature events. Such temperature spikes during the reproductive stage of plant development can harm crop fertility and productivity.

Plants, 2016 In temperate climates, most plants flower during the warmer season of the year to avoid negative effects of low temperatures on reproduction. Nevertheless, few species bloom in midwinter and early spring despite severe and frequent frosts at that time ...

Sexual Plant Reproduction [PDF]
Annals of Botany, 2011 Flowering plants are the most successful group of land plants, containing over 90 % of species and dominating almost every terrestrial ecosystem. This evolutionary success is due, in part, to their sophisticated reproductive biology centred on the eponymous flower, where female gametophytes are hidden and protected by the sporophyte carpel/pistil ...
