Expression study of stress-related genes in salinity-treated transgenic Arabidopsis harboring soybean Response Regulator 34

Owing to their sessile nature, plants are easily affected by various extenal factors. Among those, drought and salinity considered as the most common stresses, which often pose a threat plant growth development. Major effects of interconnected drive similar series molecular changes in plants. These alterations response stress under regulation signaling pathways, including engangement evolutionarily conserved two-component systems (TCSs). Three components with distinct functions can be found functional TCS, histidine kinases (HKs), histidine-containing phosphotransfer proteins (HPts), regulator (RRs). Previous research revealed that soybean (Glycine max) GmRR34 acts an important regulatory protein conditions. In this project, investigation on role osmotic responses was extended examining expression subset salinity-responsive genes using RT-qPCR method. Our analyses showed transgenic Arabidopsis ectopically expressing displayed enhanced several stress-related genes, Catalase 1 (CAT1), Stromal ascorbate peroxidase (sAPX1), Copper/zinc superoxide dismutase (CSD1), Sodium/hydrogen exchanger (NHX1) Salt overly sensitive 2 (SOS2). results indicate GmRR34-transgenic might more salt-tolerant thanks stronger activities antioxidant enzymes better capacity maintaining cytosolic ion homeostasis. Therefore, it is highlighted necessity perform further studies fully characterize biological well explore its application potential enhancing salt tolerance crop
