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 3, Page 1509-1526, February 2026.Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North

Dormancy-breaking requirements of Sophora tomentosa and Erythrina speciosa (Fabaceae) seeds
Revista de Biología Tropical, 2015 The physical dormancy of seeds has been poorly studied in species from tropical forests, such as the Atlantic Forest. This study aimed to examine the effect of moderate alternating temperatures on breaking the physical dormancy of seeds, the ...

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 ...

New Phytologist, Volume 249, Issue 4, Page 1644-1658, February 2026.Summary Calcium (Ca2+) signaling is integral to nearly all aspects of plant biology, including development and responses to biotic and abiotic stresses. It operates through two main layers: the generation of Ca2+ signals and their decoding by Ca2+‐binding proteins, which act early in diverse signaling pathways. The system exhibits remarkable robustness

Dormancy and germination in Talipariti elatum seeds [PDF]
The dormancy in fresh seeds of Talipariti elatum (Sw.) Fryxell from moist evergreen forest and secondary vegetation was determined. Structural and germinative variables of the seeds were studied, and water absorption dynamics of intact and scarified ...
