Can species adapt to drought using multiple strategies? Lessons from the California poppy

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2918-2932, June 2026.
Summary Plants can escape drought by completing life cycles early, tolerate drought by increasing physiological limits, or avoid drought stress by obtaining or using water more efficiently. It remains unclear whether strategies vary within species across their distributional ranges due to trade‐offs, and whether species can exhibit plasticity in ...

Semillas y raíces

open access: yesAletheia, revista de desarrollo humano educativo y social contemporáneo
This article aims to articulate philosophical knowledge to social work, linking it with the "Semillas y Raíces" (Seeds and Roots) Foundation located in Commune 4 (Altos de Cazucá) in Soacha, Colombia. The community processes that occur in this non-profit are emancipatory, due to their political and aesthetic factors. The political is viewed through the

Root and microbial contributions to anoxic microsite formation in the rhizosphere: a microfluidic approach

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3486-3498, June 2026.
Summary Plant root‐associated anoxic microsites may influence the fate of nutrients and contaminants in the rhizosphere, but their dynamics remain relatively unknown. To examine the formation of root‐induced anoxic microsites over space and time, we use microfluidic devices integrated with transparent, planar oxygen sensors in a wheat (Triticum ...

Structure and sequence evolution in the pennycress (Thlaspi arvense) pangenome

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2723-2741, June 2026.
Summary Eukaryotic genomes harbor many forms of variation, including nucleotide diversity and structural polymorphisms, which experience natural selection and contribute to genome evolution and biodiversity. Harnessing this variation for agriculture hinges on our ability to detect, quantify, catalog, and deploy genetic diversity. Here, we explore seven

Nucleomorph phylogenomics suggests a deep and ancient origin of cryptophyte plastids within Rhodophyta

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3103-3113, June 2026.
Summary The evolutionary origin of red algae‐derived complex plastids remains obscure. Cryptophyta, one of four eukaryotic lineages harboring these plastids, still contains nucleomorphs, which are highly reduced remnants of red algal nuclei. The genes present on nucleomorph genomes can be used for phylogenomic reconstruction in order to unravel the ...
