Temperature‐dependent pollinator‐mediated selection on floral thermoregulation
New 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

New Phytologist, Volume 249, Issue 3, Page 1268-1282, February 2026.Summary Exogenously applied auxins are essential for establishing cell lines in tissue cultures and maintaining their proliferation. Cell lines may develop the ability to proliferate even in media lacking auxin, they may become auxin‐habituated. This study investigated the mechanisms underlying this process.

Contemporary hybridization among Arabis floodplain species creates opportunities for adaptation
New 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 ...

New Phytologist, Volume 249, Issue 4, Page 2125-2139, February 2026.Summary Agrobacterium‐mediated transformation by floral inoculation (AMT‐FI) enables genetic engineering without tissue culture. It is widely used in the model plant Arabidopsis thaliana, yet its efficiency and broader applicability remain limited. Here, we used a dual‐reporter system (RUBY and hygromycin resistance) to identify key floral stages and ...
