Leaf Tissue‐Specific Phosphorus Allocation Is Linked to Leaf Lifespan in Chickpea Accessions

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants strategically allocate phosphorus (P) among leaf tissues to support physiological functions. However, there is limited understanding of contrasting leaf cellular P‐allocation patterns and their physiological consequences. We quantified leaf P fractions, photosynthetic P‐use efficiency (PPUE), and P‐remobilisation efficiency (PRE) in ...

Growth Temperature Alters the Thermal Sensitivity of Mesophyll Conductance in Wild and Cultivated Tomato

Plant, Cell &Environment, EarlyView.
ABSTRACT Mesophyll conductance (gm) is a key component of internal CO2 diffusion and can limit photosynthesis in C3 leaves. Temperature responses of gm are commonly treated as intrinsic properties of the leaf, yet it remains unclear whether they acclimate to growth conditions. Here, we tested whether growth temperature alters the thermal sensitivity of

Daily Heat Stress Induces Donor‐Side Limitation of PSI Via Downregulation of the Cyt b6f Complex

Plant, Cell &Environment, EarlyView.
ABSTRACT The rapidly warming climate is driving increasingly frequent and intense heat waves worldwide, posing major challenges to plant metabolism and growth. Despite the central role of photosynthesis in plant growth, the effects of prolonged heat stress on the primary reactions of photosynthesis remain poorly understood.

Early‐Season Warming Advances Autumn Senescence in Temperate Tree Saplings in Association With Early Growth Dynamics

Plant, Cell &Environment, EarlyView.
ABSTRACT The timing of autumn leaf senescence is driven by external cues such as temperature and photoperiod and is strongly regulated by internal developmental processes. Correlative evidence suggests that earlier budburst and warmer conditions in spring and summer could accelerate development and advance senescence, yet this hypothesis remains ...

Design Principles of Plant Thermotolerance: Integrating Photosynthesis, Reproduction, and Field Resilience in a Warming Climate

Plant, Cell &Environment, EarlyView.
ABSTRACT Global food security is increasingly threatened by climate change, as rising temperatures compromise the yields of major staple crops, including wheat, rice, and maize. Enhancing plant thermotolerance has therefore become a critical priority for sustaining agricultural productivity.

Ozone Susceptibility of Tropical Tree Species

Plant, Cell &Environment, EarlyView.
ABSTRACT Tropical forests account for approximately 60% of global terrestrial photosynthesis, yet their function into the future may be compromised by rising ground‐level ozone (O3) pollution. Although O3 is known to impair plant productivity, the physiological mechanisms underlying interspecific variation in O3 susceptibility—especially among tropical
