Abstract

Catalase (CAT) controls plant growth and development primarily by scavenging H₂O₂ from reactive oxygen species (ROS). As an antioxidant enzyme, catalase reduces ROS by converting H₂O₂ into H₂O to shield cells from oxidative stress-induced apoptosis. The CAT gene family has been identified in many plants except Sorghum bicolor. In this study, five SbCAT proteins encoded by three genes were identified in the genome of S. bicolor. Three conserved amino acids, one active catalytic site, one heme-ligand signature, and three peroxisomal targeting signal 1 (PTS1) sequences were shared by all SbCAT proteins. The presence of different cis-regulatory elements indicated that SbCAT genes might be involved in the developmental and stress adaptation pathways. SbCAT genes showed variable expression in various tissues and responses to hormonal, abiotic, and biotic stresses. The findings from this study may aid in future research on the functions of SbCAT genes in stress modulation and crop improvement.

期刊介绍： Plant Gene publishes papers that focus on the regulation, expression, function and evolution of genes in plants, algae and other photosynthesizing organisms (e.g., cyanobacteria), and plant-associated microorganisms. Plant Gene strives to be a diverse plant journal and topics in multiple fields will be considered for publication. Although not limited to the following, some general topics include: Gene discovery and characterization, Gene regulation in response to environmental stress (e.g., salinity, drought, etc.), Genetic effects of transposable elements, Genetic control of secondary metabolic pathways and metabolic enzymes. Herbal Medicine - regulation and medicinal properties of plant products, Plant hormonal signaling, Plant evolutionary genetics, molecular evolution, population genetics, and phylogenetics, Profiling of plant gene expression and genetic variation, Plant-microbe interactions (e.g., influence of endophytes on gene expression; horizontal gene transfer studies; etc.), Agricultural genetics - biotechnology and crop improvement.
