Summary
In the environment, plants are continuously being exposed to several adverse conditions. Environmental stress conditions such as drought, heat, salinity, cold, or pathogen infection can have a devastating impact on plants under field conditions. Plant responses to these stresses are complex and involve numerous physiological, molecular, and cellular adaptations.
Callose accumulation, quercetin increase, changes in ion fluxes, modifications in proline content, ROS, and phytohormones are the first responses induced to fight the stress, and the resulting signal transduction triggers metabolic reprogramming towards defense.
In addition, plants have developed intricate mechanisms to adapt and survive under various types of stresses. This results in massive transcriptional reprogramming that can make the plant tolerant or not. Primary metabolism plays a key role in plants’ adaptive/defense response through the influence on the modulation of secondary metabolism and the activation of the host’s various defense mechanisms. Alterations in metabolism can incorporate modifications in leaf gas exchange, the availability of nutrients, metabolically active compounds, or in carbon and nitrogen metabolism and C/N balance.
Understanding the complex interaction between these stresses and plants is crucial for developing effective and sustainable strategies to counterbalance their impact on crops. In fact, exposure of plants to biotic and abiotic stress induces a disruption in plant metabolism implying physiological costs, and thus leading to a reduction in fitness and ultimately in productivity.
For this research topic, we welcome reviews, perspectives, original research, opinions, and methods that highlight the latest exciting progress in understanding systems biology and the molecular, physiological, and biochemical responses of plants to abiotic and biotic stresses. Potential subjects for this topic include, but are not limited to:
· Climate change effects on plant development
· Physiology and biochemistry correlated to biotic and abiotic stresses
· Plant tolerance and acclimation mechanisms
· Biostimulants for coping with biotic and abiotic stresses
· Soil management strategies and canopy management
· Sustainable techniques to control plant pathogens
· Genomics, transcriptomics, proteomics, and metabolomics activities, to provide insights into the molecular pathways involved in stress perception, signal transduction, and stress tolerance mechanisms in plants
