Jasmonic acid negatively regulation of root growth in Japonica rice (Oryza sativa L.) under cadmium treatment

To explore the role of jasmonic acid (JA) in seed germination of japonica rice under Cadmium (Cd) stress, the growth indices of japonica rice varieties under the bud stage were measured for identifying the variety difference in Cd tolerance. Then the tolerant variety JJ818 and the sensitive one NJ91...

Description
Summary:To explore the role of jasmonic acid (JA) in seed germination of japonica rice under Cadmium (Cd) stress, the growth indices of japonica rice varieties under the bud stage were measured for identifying the variety difference in Cd tolerance. Then the tolerant variety JJ818 and the sensitive one NJ9108 were treated under 150 μmol L −1 Cd concentration, 0.5 μmol L −1 methyl jasmonate (MeJA), and 10 μmol L −1 Ibuprofen (IBU) alone or in combination to study the molecular mechanism. In addition to the germination phenotype (germination rate, root length and bud length), soluble protein content, soluble sugar content, and sugar components, α-amylase activity, and its related gene expression were also measured. The results showed that Cd treatment restricted the root length of rice seed ( P
