Abstract
Biofortification is receiving more devotion to enhance the Phyto-availability of micronutrients such as Fe, Zn, and Se, in the major food crops. Isolation of selenorhizobacteria was done on a nutrient agar plate supplemented with Na2SeO3. Among them, the best strain MPJ12 was chosen due to its Plant Growth Promoting Rhizobacteria (PGPR) characteristics, including its capacity to produce siderophore, phosphate, ammonia, etc., Selenorhizobacteria were further applied for Vigna radiata pot study with selenium-deficient soil. MPJ12 strain was identified as Bacillus mycoides by 16S rRNA sequencing method. The strain was submitted to NCBI under accession no. MG694542. Pot study indicates there was an increase in the vegetative parameters like root and shoot length. Bacillus mycoides are capable to enhance selenium content by 0.89 ppm in Vigna radiata as well as in leaves, roots, and shoots of Vigna radiata. The use of selenorhizobacterial microbes that endorse Vigna radiata growth is becoming an effective sustainable agricultural approach to substitute synthetic fertilizers, pesticides, and supplements in selenium-deficient regions.
