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 ...

Semillas y raíces

Aletheia, 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

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

New 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

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

New 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.

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.
