Identification of Rice Specific Drought Responsive Candidate Genes in Aba Independent Pathway From Tolerant and Susceptible Varieties of Oryza Sativa L.

For two-thirds of the world's population, rice, the second-most-cultivated cereal, is essential.The creation of drought-tolerant cultivars is necessary since crop quality and productivity are impacted by drought stress.On 24 rice types, a study examined 14 potential genes from the ABA independent pathway.The findings demonstrated that genes relevant to drought were present in tolerant species clones and present in vulnerable accessions.This suggests a complicated system involving numerous genes operating in various pathways to determine whether a genotype is resistant to or tolerant of drought.This strategy aids in boosting food availability and satisfying rising worldwide demand.Rice, in present study, 14 putative candidate genes belonging to abscisic acid (ABA) independent pathway were screened on 24 different rice (Oryza sativa L.) varieties.The existence of a few drought responsive genes in susceptible accessions of O. sativa and absence of some drought specific genes in tolerant species clones were noticed.This observation leads to the existence of complex machinery involving several genes in multiple pathways that finally makes a genotype susceptible or tolerant to drought.
