Post-pollination sepal longevity of female flower co-regulated by energy-associated multiple pathways in dioecious spinach

open access: yesFrontiers 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

EVOLUTION OF DIOECY FROM GYNODIOECY [PDF]

open access: yesEvolution, 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 ...

The wild grape genome sequence provides insights into the transition from dioecy to hermaphroditism during grape domestication

open access: yesGenome Biology, 2020
A key step in domestication of the grapevine was the transition from separate sexes (dioecy) in wild Vitis vinifera ssp. sylvestris (V. sylvestris) to hermaphroditism in cultivated Vitis vinifera ssp. sativa (V. vinifera). It is known that V.

Is the High Proportion of Males in a Population of the Self-Incompatible Fraxinus platypoda (Oleaceae) Indicative of True Androdioecy or Cryptic-Dioecy?

open access: yesPlants, 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.

Gynodioecy to dioecy: are we there yet? [PDF]

open access: yesAnnals of Botany, 2011
The 'gynodioecy-dioecy pathway' is considered to be one of the most important evolutionary routes from hermaphroditism to separate sexes (dioecy). Despite a large accumulation of evidence for female seed fertility advantages in gynodioecious species (females and hermaphrodites coexist) in support of the first step in the gynodioecy-dioecy pathway, we ...

Adaptation of the autosomal part of the genome on the presence of dioecy

open access: yesbioRxiv, 2021
We have attempted to answer the question of whether the presence of sex chromosomes in the genome can affect the evolution of the autosomal part of the genome. As a model, we used dioecious plants from the section Otites of the genus Silene.

Genetic insights into the dissolution of dioecy in diploid persimmon Diospyros oleifera Cheng [PDF]

open access: yes, 2023
BACKGROUND: Dioecy, a sexual system of single-sexual (gynoecious/androecious) individuals, is rare in flowering plants. This rarity may be a result of the frequent transition from dioecy into systems with co-sexual individuals. RESULTS: In this study, co-

Translocation heterozygosity in southern African species of Viscum

open access: yesBothalia: African Biodiversity & Conservation, 1980
Sex-associated and floating translocation complexes are characteristic of dioecious species of  Viscum,  but are virtually absent in monoecious species.

Salix gordejevii females exhibit more resistance against wind erosion than males under aeolian environment

open access: yesFrontiers in Plant Science, 2022
Effects of wind erosion on growth and adaptability have been widely reported in many plants, but little attention has been paid to dioecious plants. Recent studies have shown that sex-specific responses to environmental changes in many plants exist.

Sex is determined by XY chromosomes across the radiation of dioecious Nepenthes pitcher plants

open access: yesEvolution Letters, 2019
Species with separate sexes (dioecy) are a minority among flowering plants, but dioecy has evolved multiple times independently in their history. The sex‐determination system and sex‐linked genomic regions are currently identified in a limited number of ...
