Abstract

Plants normally change their hormone levels in response to biotic and abiotic stresses. Since RON1 affects either signaling or biosynthesis of hormones abscisic acid (ABA), Indol Acetic Acid (IAA) and Ethylene (C2H4), therefore, The effect of change in RON1 activity on several morphological characteristics including vein pattern, lateral root formation, hairy root, stem, root and apical has been investigated. Hereby, morphological and molecular characteristics of ron1-1 mutant was evaluated and compared with the Ler-0 wild type plants in response to different concentrations of hormone IAA, ABA and ACC in vitro conditions. Based on the obtained results, there is a significant difference between primary root length, lateral root number, leaf number and rate of germination in mutant seedlings ron1-1 when compared with the wild type seedlings in response to Different concentrations of ABA, ACC, and IAA. Moreover, Investigation of cotyledon and leaf veins in ron1-1 mutant showed that secondary veins give open networks in ron1-1, while genotype Ler-0 has joined the network of veins. Overall, the results here indicate that a considerable increase in sensitivity of ron1-1 and old101 mutant plants to hormonal -induced stress has been observed in mutant seedlings comparison with the Ler-0 plants. RON1 enzyme activity has gone in ron1-1 plants, which causes PAP ACCumulation and possibly IP3 in mutant, changing the morphological characteristics associated with the mutant seedlings.
