Interplay between high‐energy quenching and state transitions in Chlamydomonas reinhardtii: a single‐cell approach

New Phytologist, EarlyView.
Summary Studying cell‐to‐cell heterogeneity is essential to understand how unicellular organisms respond to stresses. We introduce a single‐cell analysis framework that enables the study of intercellular heterogeneity of photosynthetic traits, particularly their interactions within individual cells that have identical genotypes, cellular contexts and ...

Selecting between two transition states by which water oxidation intermediates on an oxide surface decay

, 2019
While catalytic mechanisms on electrode surfaces have been proposed for decades, the pathways by which the product's chemical bonds evolve from the initial charge-trapping intermediates have not been resolved in time.

Weighing the options: a test of alternative stomatal optimisation models at high temperatures

New Phytologist, EarlyView.
Summary Stomatal optimisation models centre upon a fundamental tradeoff for plants: opening stomata promotes carbon uptake, but closing stomata prevents water loss. However, stomatal opening can occur at high temperatures, causing evaporative cooling which limits thermal damage to leaves.

Fascinating single‐cell red algae: models for evolution and adaptation

New Phytologist, EarlyView.
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

The Effect of Low Temperature and Low Illumination Intensity on the Photosynthetic Characteristics and Antioxidant Enzyme Activity in the Strawberry

Agronomy
Low temperature (LT) and low illumination (LI) are common meteorological factors posing a great risk to plants. This study aimed to clarify and quantify the effects of LT, LI, and their combined stress (LTLI) on the photosynthetic physiological processes

Metacaspases contribute to the cellular response to heat stress in a marine diatom

New Phytologist, EarlyView.
Summary Climate‐driven marine heatwaves (HW) are extreme, large‐scale events characterized by elevated ocean temperatures lasting from days to months. Despite their importance, little is known about the molecular mechanisms of algal response to marine HW. Recent studies suggest that metacaspases play an important role in thermotolerance.

Beyond high‐throughput: leveraging plant phenotyping to improve understanding and prediction of plant growth through process‐based models

New Phytologist, EarlyView.
Summary The last decade has marked a period of rapid innovation in high‐throughput phenotyping (HTP) of plants. This includes the establishment of robotic phenotyping infrastructure, development of new sensors, and improvements in computation for downstream analysis.

Mitochondrial β‐carbonic anhydrase is a conserved metabolic rheostat for branched‐chain amino acid catabolism and metabolic flexibility

New Phytologist, EarlyView.
Summary Carbonic anhydrases (CAs) are ubiquitous metalloenzymes that catalyze the reversible hydration of CO2, enabling fundamental processes in organisms across all domains of life. Among all CAs, the role of mitochondrial βCA remains poorly understood. Here, we identify a mitochondrial βCA, βCA6, as a key regulator of branched‐chain amino acid (BCAA)
