Loss of E3 ligase HvST1 function substantially increases distal crossover frequency

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1325-1341, February 2026.
Summary This study characterizes the function of a grass‐specific E3 ubiquitin ligase, HvST1, in regulating synapsis and crossover (CO) formation during meiosis in barley (Hordeum vulgare). In large‐genome cereals, COs are predominantly restricted to distal chromosomal regions, limiting genetic recombination and breeding flexibility.

Fine‐tuning the buzz: comparing visitation frequency and pollination effectiveness in plant–pollinator networks

open access: yesNew Phytologist, Volume 249, Issue 4, Page 2140-2152, February 2026.
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.

Temperature‐dependent pollinator‐mediated selection on floral thermoregulation

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1716-1726, February 2026.
Summary The thermal environment is one of the most pervasive agents of selection. Most plants cannot choose their microclimate, so understanding how they cope with thermal variability is of critical concern. Several floral traits can modify the floral thermal microenvironment, which may alleviate negative impacts of thermal extremes on gametophytes and

Aphid parasitism alters induced plant responses allowing a hyperparasitoid to locate its hidden parasitoid host

open access: yesNew Phytologist, Volume 249, Issue 4, Page 2055-2070, February 2026.
Summary Plants typically host insect communities composed of multiple trophic levels that are intricately linked through interactions mediated by the shared food plant. Hyperparasitoids are top‐level carnivores in such systems, preying on parasitoid larvae developing inside herbivores. These hyperparasitoids can dramatically reduce the effectiveness of

Contemporary hybridization among Arabis floodplain species creates opportunities for adaptation

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1542-1557, February 2026.
Summary Hybridization between closely related species is increasingly recognized as a major source of biodiversity. Yet, whether it can create advantageous trait combinations while purging harmful alleles remains unknown. To address this question, we studied Arabis nemorensis and Arabis sagittata, two endangered species that currently hybridize in a ...
