Sex‐specific ethylene responses drive floral sexual plasticity in Cannabis sativa

The Plant Journal, Volume 125, Issue 3, February 2026.
SUMMARY Cannabis sativa L. exhibits pronounced sexual plasticity in which both XX and XY plants can undergo floral phenotypic sex reversal in response to ethylene modulation, yet the underlying molecular mechanisms remain poorly defined. Here, we present the most extensive multi‐omic analysis of ethylene‐induced sex change in C.

Toward an art of genomic selection in vegetable breeding

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Genomic selection (GS) is a powerful strategy for accelerating genetic gain in plant breeding. While in recent years GS has been widely adopted in breeding programs for agronomic crops, its implementation in vegetable breeding has been comparatively limited.

Characteristics of Sex Expression in Monoecious Persimmons.

Engei Gakkai zasshi, 1992
A persimmon (Diospyros kaki) tree may manifest three types of flowers; female, male, and perfect (hermaphrodite). Most cultivars bear only female flowers but others have both female and male and sometimes perfect flowers as well. In monoecious or polygamous cultivars, sex expression has been observed to be modified by the previous year's fruit load and

Small-scale and regional spatial dynamics of an annual plant with contrasting sexual systems [PDF]

, 2017
Plant demography is known to depend on both spatial dynamics and life history, but how these two factors interact is poorly understood. We conducted a longitudinal study of the wind-pollinated annual plant Mercurialis annua that varies geographically in ...

Genomic‐Guided Conservation Actions to Restore the Most Endangered Conifer in the Mediterranean Basin

Molecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Species with extremely small population sizes are critically endangered because of reduced genetic diversity, increased inbreeding and hybridisation threats. Genomic tools significantly advance conservation by revealing genetic insights into endangered species, notably in monitoring frameworks.

Genome Architecture and Speciation in Plants and Animals

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.

Rate of Natural Outcrossing in Monoecious Cucumbers

HortScience, 1985
Abstract The rate of natural outcrossing in cucumber (Cucumis sativus L.) was measured at 3 locations in North Carolina, using the dominant allele for scab resistance as the marker gene. Outcrossing was measured within and between 1.5 m plots in isolation blocks.

Dioecy in a wind‐pollinated herb explained by disruptive selection on sex allocation via inbreeding avoidance

New Phytologist, Volume 247, Issue 6, Page 2733-2745, September 2025.
Summary The evolution of dioecy from hermaphroditism is widely thought to be a response to disruptive selection favoring males and females, driven by advantages of inbreeding avoidance, sexual specialization, or both. It has hitherto been difficult to uncouple the importance of these two hypotheses.

Tree of Sex: A database of sexual systems [PDF]

, 2014
The vast majority of eukaryotic organisms reproduce sexually, yet the nature of the sexual system and the mechanism of sex determination often vary remarkably, even among closely related species. Some species of animals and plants change sex across their
