Variation in responses to temperature in admixed Populus genotypes predicts geographic shifts in regions where hybrids are favored

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.

Floral stage optimization and immune evasion enhance Agrobacterium‐mediated genome editing in Arabidopsis

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 ...

Calcium signaling in crops

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

Root cell wall plasticity in iron homeostasis: an overlooked frontier in plant nutrition

New Phytologist, Volume 249, Issue 4, Page 1699-1708, February 2026.
Summary Iron (Fe) is an essential micronutrient for plant growth and development, yet its availability in soils is often limited or excessive, leading to widespread Fe deficiency or toxicity that constrains crop productivity. While Fe uptake, transport, and signaling pathways have been well characterized, the role of the root cell wall as a dynamic ...

Estudio de la estructura molecular en sistemas flexibles

, 2014
El estudio espectroscópico de moléculas que presentan vibraciones de gran amplitud ha conducido a reconsiderar el concepto de estructura molecular asociada a estas vibraciones. En este trabajo se ha empleado la molécula 3,3-dimetiloxetano, heterociclo de cuatro miembros, con una función de potencial de doble mínimo para el modo de ciclo fuera del plano
