Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

New Phytologist, Volume 251, Issue 1, Page 505-522, July 2026.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

Molecular Mechanism Underlying Derepressed Male Production in Hexaploid Persimmon

Frontiers in Plant Science, 2020
Sex expression in plants is often flexible and contributes to the maintenance of genetic diversity within a species. In diploid persimmons (the genus Diospyros), the sexuality is controlled by the Y chromosome-encoded small-RNA gene, OGI, and its ...

The quest for molecular regulation underlying unisexual flower development

Frontiers in Plant Science, 2016
The understanding of the molecular mechanisms responsible for the making of a unisexual flower has been a long-standing quest in plant biology. Plants with male and female flowers can be divided mainly into two categories: dioecious and monoecious, and ...

The Red Queen unveils the sexual and mating strategies of flowers

Journal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

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.

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.
