Cell wall water shields stomata against falling leaf airspace humidity
New Phytologist, Volume 250, Issue 2, Page 861-872, April 2026.Summary Plants lose water by transpiration through stomatal pores. However, it remains a matter of debate whether relative humidity (RH) in the substomatal cavity may fall below saturation and guard cells experience strong differences water potential driven by RH in the cavity.

New Phytologist, Volume 250, Issue 2, Page 1313-1329, April 2026.Summary With current climate trajectories, tree populations will encounter novel selection pressures that risk local extinction if they are unable to acclimate or adapt. Within a reciprocal transplant experiment with Quercus macrocarpa L. established across a latitudinal gradient, we asked: (1) Is there genetic variation within populations?

New Phytologist, Volume 250, Issue 2, Page 1330-1347, April 2026.Summary Stomatal development has emerged as a valuable model for studying developmental processes. Examining gene function along the stomatal lineage often requires gene perturbation in a controlled and cell‐stage‐specific manner, but this remains tedious without a dedicated genetic tool.

Dormancy-breaking requirements of Sophora tomentosa and Erythrina speciosa (Fabaceae) seeds
Revista de Biología Tropical, 2015 The physical dormancy of seeds has been poorly studied in species from tropical forests, such as the Atlantic Forest. This study aimed to examine the effect of moderate alternating temperatures on breaking the physical dormancy of seeds, the ...

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 603-610, March 2026.‘Greening’ is often depicted as an inherently benevolent practice, turning arid stretches of land into arable and fertile plots. However, by considering a longer history of place and taking archival records into account, such transformations are rendered more complex and, often, more fraught.

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 486-498, March 2026.Iron deficiency anaemia remains a major public health challenge in Sub‐Saharan Africa, where population growth, displacement and limited resources heighten nutritional insecurity. We compiled a list of indigenous African underutilized wild food plants and examined their potential for addressing micronutrient deficiencies.

Catalysts for change: Museum gardens in a planetary emergency
PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 401-410, March 2026.Natural history museums are often seen as places with indoor galleries full of dry‐dusty specimens, usually of animals. But if they have gardens associated with them, museums can use living plants to create narratives that link outside spaces to inside galleries, bringing to life the challenges facing biodiversity.

Ciencia, Tecnología y Política, 2018 Desde mediados del siglo veinte dos hechos impactaron decisivamente en la producción y comercialización de semillas: la aparición de las semillas híbridas, y la expansión de las biotecnologías aplicadas al agro, que condujo a un salto en la privatización del conocimiento.
