Reversibility of sex changes in the plant kingdom: more important than we thought? [PDF]
Biol Rev Camb Philos SocABSTRACT Compared to animals, plants show a wide range of reproductive strategies with different degrees of sex separation (e.g. dioecy, monoecy, hermaphroditism). While sex expression was previously thought to be genetically determined and fixed in plants, accumulating evidence suggests that sex expression can change reversibly even within one ...

Cryptic dioecy and leaky dioecy in endemic species of Dombeya (Sterculiaceae) on La Re´union [PDF]
American Journal of Botany, 1999 The high frequency of dioecy on oceanic islands such as Hawaii and New Zealand has attracted a great deal of attention from plant evolutionary biologists. One reason suggested for the high prevalence of dioecy on oceanic islands is that taxa considered truly dioecious may have occasional hermaphrodite flowers, i.e., show leaky dioecy. In this study, we

PLoS ONE, 2011 In the plant genus Silene, separate sexes and sex chromosomes are believed to have evolved twice. Silene species that are wholly or largely hermaphroditic are assumed to represent the ancestral state from which dioecy evolved.

Frontiers in Plant Science, 2022 Reproductive growth is a bioenergetic process with high energy consumption. Pollination induces female flower longevity in spinach by accelerating sepal retention and development. Cellular bioenergetics involved in cellular growth is at the foundation of

The rapid dissolution of dioecy by experimental evolution [PDF]
Current Biology, 2021 Evolutionary transitions from hermaphroditism to dioecy have been common in flowering plants,1,2 but recent analysis also points to frequent reversions from dioecy to hermaphroditism.2-4 Here, we use experimental evolution to expose a mechanism for such reversions, validating an explanation for the scattered phylogenetic distribution of dioecy.

PLoS Genetics, 2020 Most angiosperms bear hermaphroditic flowers, but a few species have evolved outcrossing strategies, such as dioecy, the presence of separate male and female individuals. We previously investigated the mechanisms underlying dioecy in diploid persimmon (D.

EVOLUTION OF DIOECY FROM GYNODIOECY [PDF]
Evolution, 1970 sions do not bear directly on the truth or falsity of my hypothesis concerning the relationship between conservatism and variation. Long's citation of Bader's conclusions as a criticism of my weighting procedure appears to depend tacitly on an assumption fairly widely made by biologists: that the coefficient of variation is the only meaningful way to ...

Plants, 2022 Androdioecy is a rare reproductive system. Fraxinus platypoda, a woody canopy species in Japan’s mountainous riparian zones, is described as a morphologically androdioecious species. In this study, we tried to detect whether F.

Terrestrial gastropods - how do they reproduce? [PDF]
Invertebrate Survival Journal, 2017 Molluscs are the most diverse group in respect of sexual systems and strategies. They can be dioecious with separate sexes or hermaphroditic. Within hermaphroditism, it is possible to distinguish a number of modifications of this type of reproduction ...
