Finding balance: the dynamic interplay between H3K27me3 writers and erasers in regulating environmental plasticity and memory

New Phytologist, Volume 249, Issue 5, Page 2241-2250, March 2026.
Summary Subject to an ever‐changing world, plants must respond to harmful conditions and environmental fluctuations. Their evolutionary success can be attributed to their plasticity in both perceiving and integrating these variations to facilitate adaptation.

Identification of a novel link connecting indole‐3‐acetamide with abscisic acid biosynthesis and signaling

New Phytologist, Volume 249, Issue 5, Page 2452-2466, March 2026.
Summary Plants orchestrate their developmental processes and responses to environmental stimuli through a sophisticated network of small signaling molecules, termed phytohormones. Among these, auxins are recognized for their role in promoting plant growth.

Apropiación de semillas

Ciencia, Tecnología y Política, 2018
Desde mediados del siglo veinte dos hechos impactaron decisivamente en la producción y comercialización de semillas: la aparición de las semillas híbridas, y la expansión de las biotecnologías aplicadas al agro, que condujo a un salto en la privatización del conocimiento.

Climate adaptation and functional constraints drive pollen evolution in Apiales

New Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

The maize mitogen‐activated protein kinase kinase kinase gene ZmMAPKKK45 is associated with multiple disease resistance

New Phytologist, Volume 249, Issue 6, Page 3003-3020, March 2026.
Summary Southern leaf blight (SLB), caused by the necrotrophic fungus Cochliobolus heterostrophus, is a major foliar disease of maize (Zea mays) world‐wide. A genome‐wide association study was performed to dissect the genetic basis of SLB resistance in maize. Functional validation was performed using mutant and transgenic analyses.
