Functional analysis of Salix purpurea genes support roles for ARR17 and GATA15 as master regulators of sex determination

open access: yesPlant Direct, 2023
The Salicaceae family is of growing interest in the study of dioecy in plants because the sex determination region (SDR) has been shown to be highly dynamic, with differing locations and heterogametic systems between species.

The Impact of Pleistocene Glacial Cycles on the Evolutionary Diversification of the Arctic‐Alpine Silene acaulis Species Complex

open access: yesMolecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT Arctic‐alpine species are highly sensitive to long‐term temperature changes and associated glacial cycles due to their occurrence in cold environments to which they are adapted and spatially restricted. Unravelling their evolutionary responses to past climatic fluctuations can provide new insights into their diversification.

The architecture of resilience: a genome assembly of Myrothamnus flabellifolia sheds light on desiccation tolerance and sex determination

open access: yesNew Phytologist, Volume 249, Issue 2, Page 1063-1084, January 2026.
Summary Myrothamnus flabellifolia is a dioecious resurrection plant endemic to southern Africa that has become an important model for understanding desiccation tolerance. Despite its ecological and medicinal significance, genomic and transcriptomic resources for the species are limited.

Season over plant sex: drivers of leaf damage and plant defence in a dioecious Mediterranean shrub

open access: yesPlant Biology, Volume 28, Issue 1, Page 314-320, January 2026.
Considering both seasons revealed higher late‐season herbivory in males than in females of Pistacia lentiscus, while overall herbivory increased and traits varied seasonally. Abstract In dioecious plants, females often prioritize reproduction over growth, potentially investing more in defence, while males grow faster but allocate fewer resources to ...

Sedum diversiflorum sp. nov. (Crassulaceae), a new species with variable merosity from the Satsunan Islands, Kagoshima, Japan

open access: yesNordic Journal of Botany, Volume 2025, Issue 12, December 2025.
We re‐examined the taxonomic status of a plant previously identified as Sedum formosanum subsp. formosanum from four islands in the Satsunan Islands, Japan. To clarify its taxonomic identity, we conducted morphological and phenological comparisons and performed molecular phylogenetic analyses based on nuclear internal transcribed spacer (ITS) and three

The island syndrome in plants on New Zealand's outlying islands: a review

open access: yesNew Zealand Journal of Botany, Volume 63, Issue 5, Page 2300-2324, December 2025.
ABSTRACT The island syndrome is defined as a suite of predictable and consistent differences between island and mainland organisms. In seed plants, much of what we know about the island syndrome comes from work in the Southwest Pacific, which is comprised of the three main islands of New Zealand and ten surrounding archipelagos.

Genomics‐Driven Monitoring of Fraxinus latifolia (Oregon Ash) to Inform Conservation and EAB‐Resistance Breeding

open access: yesMolecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Understanding the evolutionary processes underlying range‐wide genomic variation is critical to designing effective conservation and restoration strategies. Evaluating the influence of connectivity, demographic change and environmental adaptation for threatened species can be invaluable to proactive conservation of evolutionary potential.

Plasticity in Sexual Dimorphism Enhances Adaptation of Dioecious Vallisneria natans Plants to Water Depth Change

open access: yesFrontiers in Plant Science, 2019
Sexual dimorphism in vegetative and reproductive traits is associated with contrasting strategies of males and females for response to varied environmental conditions, causing sex-specific reproduction success and consequently long-distance dispersal and
