Buscando al polinizador eficiente: variación temporal en el gremio de visitantes florales y carga polínica estigmática en la especie distílica Palicourea padifolia (Rubiaceae)

Revista Mexicana de Biodiversidad, 2018
Las especies distílicas exhiben una altura recíproca en la separación (hercogamia) entre el estigma y las anteras de los morfos florales. El significado adaptativo de este polimorfismo floral es promover la  transferencia de polen entre el morfo Pin y ...

Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

New Phytologist, Volume 249, Issue 5, Page 2515-2530, March 2026.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

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.

Understanding the dynamic nature of plant lipid anabolic and catabolic metabolism is key to sustainable oilseed engineering

New Phytologist, Volume 249, Issue 5, Page 2196-2214, March 2026.
Summary Plant‐derived oils are essential sources of reduced carbon and various fatty acid (FA) structures for food, biofuels, and the oleochemical industry. Despite extensive efforts, engineering mainstream oilseed crops to produce high levels of industrially valuable unusual FAs (UFAs) remains challenging.

The environmentally responsive plant epigenome: insights from jasmonate signaling

New Phytologist, Volume 249, Issue 6, Page 2722-2728, March 2026.
Summary The environmental responsiveness of the plant epigenome is essential for spatiotemporally precise gene regulation, enabling plants to adapt to external cues. Elucidating the mechanisms underlying this responsiveness is therefore fundamental to deciphering the molecular logic of plant‐environment interactions.

Testing macroevolutionary predictions of the Grant‐Stebbins model in the origin of Aeschynanthus acuminatus

New Phytologist, Volume 249, Issue 6, Page 3137-3148, March 2026.
Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.

Engineering next‐generation crops through CRISPR‐mediated horizontal gene transfer

New Phytologist, Volume 249, Issue 6, Page 2683-2689, March 2026.
Summary Crops increasingly face overlapping stresses such as heat, drought, salinity, and pathogens that conventional breeding or genome editing rarely overcome in combination. To address this, we propose CRISPR‐enabled horizontal gene transfer (CRISPR‐HGT) as a programmable framework that recreates the evolutionary process by which plants historically
