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.

Genotypic differences in proembryoid development and green plantlets regeneration through androgenesis in barley varieties Diferenças genotípicas no desenvolvimento de pró-embrióides e regeneração de plântulas verdes via androgênese em genótipo de cevada

Ciência Rural, 2008
The development of in vitro haploid plants followed by spontaneous or induced genome duplication allows to achieve, in one generation, the recovery of total homozygosis. The efficiency of the haplodiploidization process through in vitro anther culture of

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.

Ontogenia dos estratos parietais da antera de Tabebuia pulcherrima Sandw. (Bignoniaceae) [PDF]

Acta Botanica Brasilica, 1997
A ontogenia do tapete e dos demais estratos parietais, bem como o desenvolvimento do estômio e deiscência da antera de Tabebuia pulcherrima, foram presentemente estudados. O padrão de formação da parede do androsporângio é do tipo Dicotiledôneo. A camada parietal primária, a camada esporogênica e o tapete interno derivam-se diretamente do meristema ...
