A mutant of Chlamydomonas without LHCSR maintains high rates of photosynthesis, but has reduced cell division rates in sinusoidal light conditions.

PLoS ONE, 2017
The LHCSR protein belongs to the light harvesting complex family of pigment-binding proteins found in oxygenic photoautotrophs. Previous studies have shown that this complex is required for the rapid induction and relaxation of excess light energy ...

Analysis of the genes of the OEE1 and OEE3 proteins of the photosystem II complex from Chlamydomonas reinhardtii

Plant Molecular Biology, 1989
The sequences of the nuclear genes of the 33 kDa (OEE1) and the 16 kDa (OEE3) polypeptides of the oxygen evolving complex of Chlamydomonas reinhardtii have been established. Comparison between the OEE1 protein sequences of C. reinhardtii and higher plants and cyanobacteria reveals 67 and 47% homology. In contrast, C.

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 ...

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...

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.

Biochemische Charakterisierung von Photosystem-I-Komplexen aus Diatomeen [PDF]

, 2009
Photosystem (PS) I is a huge membrane protein complex which coordinates around 200 co-factors. Upon light excitation a charge separation at the PS I reaction centre is induced which leads to an electron transport across the thylakoid membrane and the ...

Effects of Atmospheric CO2 Levels on the Susceptibility of Maize to Diverse Pathogens

Plant, Cell &Environment, EarlyView.
ABSTRACT Rising atmospheric CO2 has significant implications for crop productivity and food security. Based on studies in C3 plants, elevated CO2 (eCO2) can shape plant‐pathogen interactions, although the outcomes are often variable. The question of how eCO2 influences immunity and disease development in C4 plants, such as the globally important cereal

Unravelling the Intraspecific Variation in Drought Responses in Seedlings of European Black Pine (Pinus Nigra J.F. Arnold)

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding intraspecific variation in drought tolerance is essential for predicting the adaptive capacity of forest species under climate change. Yet, the molecular basis of this variation remains poorly understood in ecologically and economically important conifers.

Multi‐Subunit Engineering of Photorespiratory Glycine Decarboxylase Refines Photosynthesis, Growth and Metabolic Robustness of Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Photorespiration secures oxygenic photosynthesis from metabolic constraints arising from the oxygenation reaction of Rubisco in today's oxygen‐rich atmosphere. Beyond this protective function, it is vital for primary metabolism, cellular redox balance, and stomatal regulation.

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.
