Physiological Processes

Among the plant nutrients, potassium (K) is one of the vital elements required for plant growth and physiology. Potassium is not only a constituent of the plant structure but it also has a regulatory function in several biochemical processes related to protein synthesis, carbohydrate metabolism, and enzyme activation. Several physiological processes depend on K, such as stomatal regulation and photosynthesis. In recent decades, K was found to provide abiotic stress tolerance. Under salt stress, K helps to maintain ion homeostasis and to regulate the osmotic balance. Under drought stress conditions, K regulates stomatal opening and helps plants adapt to water deficits. Many reports support the notion that K enhances antioxidant defense in plants and therefore protects them from oxidative stress under various environmental adversities. In addition, this element provides some cellular signaling alone or in association with other signaling molecules and phytohormones. Although considerable progress has been made in understanding K-induced abiotic stress tolerance in plants, the exact molecular mechanisms of these protections are still under investigation. In this review, we summarized the recent literature on the biological functions of K, its uptake, its translocation, and its role in plant abiotic stress tolerance.

Efficient Utilization

Tomato, one of the most important crops worldwide, has a high demand in the fresh fruit market and processed food industries. Despite having considerably high productivity, continuous supply as per the market demand is hard to achieve, mostly because of periodic losses occurring due to biotic as well as abiotic stresses. Although tomato is a temperate crop, it is grown in almost all the climatic zones because of widespread demand, which makes it challenge to adapt in diverse conditions. Development of tomato cultivars with enhanced abiotic stress tolerance is one of the most sustainable approaches for its successful production. In this regard, efforts are being made to understand the stress tolerance mechanism, gene discovery, and interaction of genetic and environmental factors. Several omics approaches, tools, and resources have already been developed for tomato growing. Modern sequencing technologies have greatly accelerated genomics and transcriptomics studies in tomato. These advancements facilitate Quantitative trait loci (QTL) mapping, genome-wide association studies (GWAS), and genomic selection (GS). However, limited efforts have been made in other omics branches like proteomics, metabolomics, and ionomics. Extensive cataloging of omics resources made here has highlighted the need for integration of omics approaches for efficient utilization of resources and a better understanding of the molecular mechanism. The information provided here will be helpful to understand the plant responses and the genetic regulatory networks involved in abiotic stress tolerance and efficient utilization of omics resources for tomato crop improvement.

Dioxygenase Enzymes

The field of biotechnology has extraordinary influence on science, law, the administrative condition social insurance, and business throughout the world. As the starting of agriculture, people have been manipulating crops to improve the yield and quantity. Product yields throughout the world are essentially diminished by the activity of herbivorous insects, pathogens, and parasites. Natural environmental stresses make this circumstance significantly worse. Biotechnology can be used to increase the yield of food crops, to improve biotic and abiotic stress tolerance, to modify the traits of the plant (e.g. oil content, percentage of lignin, cell structure), to make the conversion to liquid biofuels more efficient. Various genes have been discovered for biotic and abiotic stress tolerance. The genes discovered for biotic stress are aryloxyalkanoate, dioxygenase, enzymes (aad-1), nitrilase, Cry1Ac, Cry2AB, GTgene, AFP (anti-freezing protein gene) gene, Chitinase II and III gene, and Rps1-k. The genes discovered for abiotic stress are SgNCED1, SgNCED1, USP2, HSP70, BADH, and ALO, PVNCED1, HVA1, LeNCED1. CRISPRs (clustered regularly interspaced short palindromic repeats) are the short DNA sequences present in bacteria and archaeal genomes which are now currently used by researchers to edit the genome. In different plant species (calli, leaf discs) protoplasts have been successfully used to edit their genome through CRISPR/Cas9 system. The aims of the applications are to increase resistance to abiotic or biotic stress, to engineer metabolic pathways, and to increase grain yield. Incorporation of modern biotechnology, with regular traditional practices in a sustainable way, can fulfill the objective of achieving food security for the present and as well as in future.
