🌿🔆 PsbS drives NPQ, but how? In Arabidopsis, T259 phosphorylation was undetectable. Mutations impaired quenching—pointing to the C-terminus stabilizing PsbS–LHCII interactions, not phosphorylation. #plantscience @jxbotany.bsky.social @sebiology.bsky.social academic.oup.com/jxb/advance-...

🌵 #CAMPlantsWeek Low internal air space in plants with crassulacean acid metabolism may be an anatomical spandrel by Alistair Leverett and co-authors in @annbot.bsky.social #openaccess article 👉https://botany.fyi/mEJf4J #PlantScience #Botany
Contrary to previous beliefs, our study challenges the notion that reduced internal air space benefits Crassulacean acid metabolism (CAM) plants. We argue that low % internal air space is likely an outcome of cellular volume optimization rather than an adaptive advantage, as stomatal closure during CAM phase III saturates internal CO2 concentrations, minimizing the impact of low mesophyll conductance on gas flux within leaves.

The orchestration of leaf vein density in succulent Clusia species reveals a strategic coordination with Crassulacean acid metabolism (CAM). CAM's influence on vascular anatomy, rather than bulk hydraulic capacitance (CFT), underscores its pivotal role in shaping water dynamics. Understanding this synergy is crucial for potential bioengineering applications in enhancing CAM traits in C3 crops.

Clusia stands alone as the sole genus of dicotyledonous trees with Crassulacean Acid Metabolism (CAM). Over 40 years of research reveals the genus's remarkable diversity and plasticity in life forms, morphology, and photosynthetic physiology. This review delves into the evolution of CAM in Clusia, considering timing, environmental conditions, and anatomical characteristics. Physiological plasticity influences species distribution and ecological range, with insights from leaf anatomical traits and CAM activity correlations. Future research opportunities include exploring the role of elevated nocturnal citric acid accumulation and gene expression in C3–CAM intermediate phenotypes in Clusia.
