CHROMIUM TOXICITY AMELIORATED BY 24-EPIBRASSINOSTEROIDS IN CORIANDRUM SATIVUM

Abstract

 Cr (VI) stress poses a significant challenge to plant growth and development, resulting in reduced yields and
economic losses in agriculture globally. Coriander is the oldest spice of the world. It is basically a leafy
vegetable rich in protein, vitamins and dietary products. 24-Epibrassinosteroids (BRs) have been identified as
regulators of stress responses, by associating with the expression of genes associated with stress. This study
aimed to investigate the effects of 24-Epibrassinosteroid on Chromium (VI) toxicity in (Coriandrum sativum)
plant. An experiment is designed to study the effect of Antioxidant hormone 24-epibrassinosteroid to eliminate
the toxicity of chromium (50 μmol and 100 μmol). The experiment consisted of two varieties (Dhania and
coriander) under Cr stress. The findings revealed that the application of 24-Epibrassinosteroids mitigate the
negative impacts of heavy metal chromium on plant growth. It resulted in significant improvements in various
parameters related to plant growth, yield and biochemical processes. Overall, the result suggested that the
application of 24-Epibrassinosteroid could effectively alleviate the detrimental effects of heavy metal stress,
ultimately enhancing the growth and productivity of coriander plants. Molecular docking presented that there is
strong affinity between 24-epibrassinosteroid (24-Ebr) and defense protein (1-Psd) with four hydrogen bonds
observed through autodock Vina. This prediction shows improved defense mechanism in peas with the
application of brassinosteroid to cope with chromium stress which needs to be farther investigated.
