How state transitions balance photosynthetic electron transport in plants – a quantitative study

New Phytologist, Volume 250, Issue 1, Page 209-229, April 2026.
Summary In plants, the process of state transition regulates the allocation of sunlight energy between Photosystem II (PSII) and PSI. However, the implications of state transitions for harmonizing electron transport rates between photosystems, and a full quantitative picture of this process, remain underexplored.

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

Papila Apical Dentaria como fuente de Células Madre: Relato del Caso

Revista de Odontopediatria Latinoamericana, 2021
Las células madre mesenquimales (MSCs) son células madre adultas que tienen la capacidad de diferenciarse en varios tipos de células. Una rica fuente de células madre mesenquimales puede ser obtenida de tejidos dentales como la papila apical. El objetivo

Future heatwave conditions inhibit CO2‐induced stomatal closure in wheat

New Phytologist, Volume 249, Issue 3, Page 1234-1252, February 2026.
Summary As global temperatures and the severity of droughts continue to increase, food crops will more frequently experience high vapour pressure deficit (VPD) during heatwave events. However, the interactive effects of rising atmospheric CO2 and high‐VPD heatwaves on crop water fluxes and yields are currently unknown.

Plasma‐activated water to foster sustainable agriculture: Evidence and quest for the fundamentals

PLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1596-1603, November 2025.
An increasing world population facing limited natural resources poses a global challenge to food security. This challenge is increasing due to climate change, which in turn is strongly affected by the food system that accounts, according to the Food and Agriculture Organization (FAO), for one‐third of the global greenhouse gas emissions.

Warm temperature modifies cell fates to reduce stomata production in Arabidopsis

New Phytologist, Volume 248, Issue 2, Page 672-689, October 2025.
Summary Stomatal abundance decrease in Arabidopsis triggered by warm temperature is attributed to PIF4‐mediated repression of SPEECHLESS (SPCH) expression. We identified the unknown developmental and transcriptional basis of this adaptive response. We traced stomatal lineages in vivo using cell‐identity marker lines and mutants, quantified epidermal ...
