Reconocimiento de las especies de gramíneas dominantes del valle de Tafí (Tucumán, Argentina) mediante análisis epidérmico foliar

Lilloa, 2000
Se estudia la epidermis foliar abaxial de 18 especies de gramíneas dominantes en el valle de Tafí. Se elabora una clave basada en caracteres de valor diagnóstico para el reconocimiento de estas especies en estado vegetativo.

Microclimate drives demographic compensation in a narrow endemic tropical species

New Phytologist, Volume 250, Issue 1, Page 166-180, April 2026.
Summary Demographic compensation occurs when reductions in some vital rates are offset by increases in others, allowing populations to maintain similar performance across varying environments. This mechanism may help explain species' ecological distributions and range limits, yet its role at microenvironmental scales remains poorly understood.

Leaf gas exchange measurement for steady‐state stomatal conductance model calibration

New Phytologist, Volume 250, Issue 1, Page 672-690, April 2026.
Summary Stomatal conductance models are essential components of crop and land surface models, but collecting data to calibrate them remains challenging due to large leaf‐to‐leaf variability, slow stomatal kinetics, and a lack of consistent measurement protocols, leading to unknown reliability and representativeness of calibrated model parameter ...

Biochemical phosphorus allocation is linked to photosynthetic phosphorus‐use efficiency in a phosphorus‐impoverished environment

New Phytologist, Volume 250, Issue 2, Page 905-920, April 2026.
Summary Highly efficient phosphorus (P)‐use strategies have evolved in plants, allowing them to thrive in severely P‐impoverished environments. However, it remains unclear how allocating leaf P to biochemical fractions, including specific P‐containing metabolites, contributes to instantaneous photosynthetic P‐use efficiency (iPPUE) and the position of ...

Circular RNA Vv‐circCOR27 modulates thermotolerance through attenuating VvHSP90.2b‐VvHsfA7a interaction in grapevine

New Phytologist, Volume 250, Issue 2, Page 988-1003, April 2026.
Summary Circular RNAs (circRNAs) are single‐stranded, covalently closed RNA molecules that arise from exon back‐splicing. The identification and function investigation of circRNAs have been comprehensively explored in plants, however, the regulatory mechanisms are largely unknown.
