The recent trend in the change in climatic conditions over the globe has significantly affected the production and productivity of horticultural crops. These changes in climatic conditions
and anthropogenic activities lead to the development of various environmental conditions, including salinity stress, sodic and alkaline soil, drought, temperature stress (low and high), and heavy metal contamination, which can have a noticeable effect on plant growth rate, yield, and quality of horticultural crops. Different horticultural crops respond differently to abiotic stressors and are especially susceptible to abiotic stress primarily during the seedling establishment, vegetative phases, reproductive stages (such as seed development, flowering, and fruiting) and senescence.
To determine the effects of abiotic stresses and the possible resistance mechanisms and/or mitigating aspects of these stresses in crops, the study of physiological, biochemical, and molecular responses in horticultural crops is of the utmost importance. Moreover, the biotic stresses, which include viruses, fungi, bacteria, insects, vectors and nematodes, substantially hamper the vigour and productivity of horticultural crops.
It is interesting to understand the role of biostimulant chemicals, hormones, novel chemicals and/or the use of microorganisms in agriculture has increased the tolerance of crop plants to abiotic and biotic stresses, allowing for enhanced yield in horticultural crops. The novel phytochemicals, secondary metabolites and antimicrobial peptides have recently been reported to mitigate the detrimental effect of abiotic and biotic stresses via the enhanced activity of enzymatic and non-enzymatic antioxidants, phytohormonal interaction, defense gene activation and systemic resistance.
In this context, we are proposing this Research Topic which will be a compilation of Original Research, Reviews and Methods articles that will impart an in-depth understanding of morphophysiological, biochemical and molecular tolerance mechanisms against abiotic and biotic factors in horticultural crops.
Sub-topics may include, but are by no means limited to:
• Current intervention on physiological and biochemical responses and mechanism of abiotic and biotic stress in horticultural crops
• Signalling mechanisms and pathways involved in the regulation of stress responses
• Phytohormonal cross-talk and associated mechanisms under stress conditions
• Epigenomics, genomics, proteomics, and metabolomics approaches in horticultural crops’ response to abiotic stress
• Osmotic adjustments and reactive species signalling in response to abiotic and biotic stress
• Transcriptional and translational regulation of stress response in horticultural crops
• Application of novel phytoprotectants in mitigation of stresses in horticultural crops
• Mechanistic insight of PGPR mediated regulation of stresses condition
