Main conclusion In this study, we identified a total of ten melatonin biosynthesis genes (3 TDCs , 2 TSHs , 3 SNATs , and 2 ASMTs ) in Chenopodium quinoa through bioinformatics methods, and analyzed physiological traits and gene expression levels in drought- and salt-treated plants with or without melatonin. Gene expression levels showed variations depending on tissues, genotypes, and abiotic stress. Abstract Melatonin is invo...

Plant glutamate receptor-like channels (GLRs) play important roles in plant development, immune response, defense signaling and Nitric oxide (NO) production. However, their involvement in abiotic stress responses, particularly in regulating Reactive Oxygen Species (ROS), is not well understood. This study aimed to investigate GLR-mediated NO production on ROS regulation in salt-stressed cells. To achieve this, Arabidopsis thal...
