ABSTRACT

Abiotic stresses reduce crop yield by about 50% worldwide. Analysis of

plants under abiotic stresses can identify the hub genes, which can help to

coordinate the plant’s response to these stresses and help to detect signaling

events to determine plant stress tolerance in the natural environment. The

difference in the response of plants to stress is related to regulatory genes.

Regulatory genes are genes whose products have a great effect, such as

hormones, enzymes, TFs, etc. In the microbial technique, thousands of genes

can be expressed simultaneously in the shortest possible time and the stressed

plant can be compared to the control plant. In recent years, this technique has

produced a large amount of gene expression data. Identifying genes that can
