Special Issue Information

Dear Colleagues,

Global warming and climate change have accompanied us for years, however now this process is happening more and more quickly and it becomes a real threat. Global warming has a negative impact on Agricultural plant production.

Therefore, study about the photosynthesis mechanism and the ability of plants to adapt to changing environmental conditions seems very important.

Plants regularly absorb light energy in excess because of fluctuations in light intensities and temperature regimes that exceed the capacity for photosynthetic capture and use. When photosynthetic and photorespiratory carbon metabolism cannot utilize absorbed light optimally and effectively, it can lead to the rapid increase of energy dissipation as heat and fluorescence, rapid foliar temperature increase, and the inhibition of photosynthesis. Thus, plants have evolved several quenching, dissipation, and avoidance mechanisms of excess energy that protect the photosynthetic apparatus and simultaneously ensure conditionally optimal photosynthesis, growth, and development.

Regulations of these processes influence biotic and abiotic stress tolerance, cell death, stomatal conductance, yield, and in general plant productivity (plant fitness). However, the exact mechanism that enables plants to regulate and balance the rates of these processes under various light and temperature conditions has not yet been clarified. Moreover, foliar heat production due to energy dissipation during photosynthesis and its inhibition is barely considered in the mechanism of photoinhibition. Studying these mechanisms is of critical importance for understanding the impact of light and temperature variations on plants’ performance and productivity in different climate conditions, especially during times of global warming.

The present Special Issue of Cells aims to summarize some of the newest advances in the regulation of photosynthesis, photoprotection, and plant productivity. We aim to highlight the key involvement of the energy dissipation process, reactive oxygen species (ROS), phytohormonal and electrical signaling including plasma membrane-localized ion channels and pumps that propagate information about Network and Systemic Acquired Acclimation (NAA and SAA) and regulation of photosynthesis, water use efficiency, plant productivity and the specific induction of cross-tolerance in plants. On the other hand, we want to examine the cellular mechanisms that lie behind the processes of repair and the recovery of functionality of photosynthetic foliar tissue in the context of high light, heat, and drought stresses.

In Arabidopsis thaliana, cysteine-rich receptor-like kinases (CRKs) constitute a large group of membrane-localized proteins which perceive external stimuli and transduce the signal into the cell. Previous reports based on their loss-of-function phenotypes and expression profile support their role in many developmental and stress-responsive pathways. Our study revealed that one member of this family, CRK5, acts as a negative regulator of leaf aging. Enrichment of the CRK5 promoter region in W-box cis-elements demonstrated that WRKY transcription factors control it. We observed significantly enhanced WRKY53 expression in crk5 and reversion of its early-senescence phenotype in the crk5 wrky53 line, suggesting a negative feedback loop between these proteins antagonistically regulating chlorophyll a and b contents. Yeast-two hybrid assay showed further that CRK5 interacts with several proteins involved in response to water deprivation or calcium signaling, while gas exchange analysis revealed a positive effect of CRK5 on water use efficiency. Consistent with that, the crk5 plants showed disturbed foliar temperature, stomatal conductance, transpiration, and increased susceptibility to osmotic stress. These traits were fully or partially reverted to wild-type phenotype in crk5 wrky53 double mutant. Obtained results suggest that WRKY53 and CRK5 are antagonistic regulators of chlorophyll synthesis/degradation, senescence, and stomatal conductance. Full article

In the environmental and organism context, oxidative stress is complex and unavoidable. Organisms simultaneously cope with a various combination of stress factors in natural conditions. For example, excess light stress is accompanied by UV stress, heat shock stress, and/or water stress. Reactive oxygen species (ROS) and antioxidant molecules, coordinated by electrical signalling (ES), are an integral part of the stress signalling network in cells and organisms. They together regulate gene expression to redirect energy to growth, acclimation, or defence, and thereby, determine cellular stress memory and stress crosstalk. In plants, both abiotic and biotic stress increase energy quenching, photorespiration, stomatal closure, and leaf temperature, while toning down photosynthesis and transpiration. Locally applied stress induces ES, ROS, retrograde signalling, cell death, and cellular light memory, then acclimation and defence responses in the local organs, whole plant, or even plant community (systemic acquired acclimation, systemic acquired resistance, network acquired acclimation). A simplified analogy can be found in animals where diseases vs. fitness and prolonged lifespan vs. faster aging, are dependent on mitochondrial ROS production and ES, and body temperature is regulated by sweating, temperature-dependent respiration, and gene regulation. In this review, we discuss the universal features of stress factors, ES, the cellular production of ROS molecules, ROS scavengers, hormones, and other regulators that coordinate life and death.
