Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

Biogeography and host associations of Russula subsection Xerampelinae based on large‐scale analysis of UNITE sequence data

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2547-2558, March 2026.
Summary Estimating fungal geographic ranges and niche potential is limited by the ephemeral nature of fruiting bodies. While environmental DNA offers broader insights, species‐level identification remains difficult due to uncertain sequence clustering thresholds, low interspecific variation in barcoding regions, and limited taxonomic resolution.

Revisiting the relationship between stomatal size and speed across species – a meta‐analysis

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.

Transcriptomic prey‐capture responses in convergently evolved carnivorous pitcher plants

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2559-2573, March 2026.
Summary The Australian pitcher plant Cephalotus and the Asian pitcher plant Nepenthes exhibit striking morphological and functional similarities, serving as compelling examples of convergent evolution. Although trapping pitchers in both lineages represent some of the most elaborate leaf structures in angiosperms, it remains unknown whether their ...

La violencia en la estructura familiar colombiana

open access: yes, 1993
Colombia “paradigma de la democracia” lleva consigo, una historia, en que la violencia ha sido el principal instrumento para dirimir los conflictos. El país se ha visto asediado por dicho flagelo, y para penetrar en ella debemos conocer sus múltiples dimensiones y manifestaciones.

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

open access: yesNew 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.
