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

open access: yesNew 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.

The environmentally responsive plant epigenome: insights from jasmonate signaling

open access: yesNew 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.

Effect of temperature shock on soybean microspore embryogenesis

open access: yesBrazilian Archives of Biology and Technology, 2004
In this study the effect of cold and heat shock on androgenetic induction in soybean anther culture was tested. Anthers of soybean were subjected to 4 and 33ºC, while the anthers used for control were maintained at 25ºC.

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

open access: yesNew 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.

Transporte diferencial de polen por colibríes en una planta diestílica: no es lo mismo picos cortos que largos

open access: yesHuitzil, 2012
Las poblaciones de plantas diestílicas usualmente tienen individuos que producen flores con estigmas largos y anteras cortas (flores longiestiladas, Pin), o individuos con estilos cortos y anteras largas (flores breviestiladas, Thrum).
