Description Not Available
Zinc (Zn) is an essential micronutrient involved in biochemical processes for growth and development of plants. Here, we
investigated the variability in response of 15 rice genotypes for number of roots, shoot and root length, metal tolerance
score under zinc sufficient (ZS) and zinc deficient (ZD) conditions using hydroponics system. Significant variation was
observed among genotypes for four traits under ZS and ZD conditions. Five genotypes were identified with promising
performance under ZD, which could be deployed in rice breeding program for zinc deficiency. Expression analysis of
OsHMA2 and OsHMA3 in root tissues of five selected zinc efficient genotypes has shown up-regulation of OsHMA3 in
three genotypes with high grain zinc. Root length was highly correlated with OsHMA2 and OsHMA3 under ZD condition.
