Deciphering morphological and biochemical modulations in mungbean by application of ethylene precursor and inhibitors under cadmium stress.

ABSTRACT: Cadmium (Cd), being one of the most toxic elements, exerts negative effects on plant growth and development. Ethylene (ET) has a prime significance in abiotic stress-induced cellular modulations and regulation of plant development. In the present study, seeds of a Cd-tolerant (NM-98) and -sensitive (NM-28) genotype were primed using 50 µM ACC (ET precursor 1-amino cyclopropane-1-carboxylic acid) and ET inhibitors (1 mM AVG/aminoethoxyvinylglycine, 0.5 mM PZA/pyrazinamide or 0.25 mM AgNO₃/silver nitrate). Subsequently, these were allowed to grow in soil containing 0 or 50 µM CdCl₂. After germination, ACC, AVG, PZA or AgNO₃ was again applied, accordingly, as foliar spray. In NM-98, application of ACC resulted in reduced root fresh (38%) and dry (38%) weight,
