Crosstalk of Ethylene and Salicylic Acid in the Amelioration of Toxic Effects of Heavy Metal Stress in Mustard

Abstract

Mustard is considered as a central crop all over the globe since it is a inexpensively important product. Plant toxicity caused by heavy metals (HMs) in agricultural fields results in a drop in yield. Using multiple ways targeting either ethylene production or the ethylene signaling system to manipulate ethylene in plants to cope with HM stress has yielded promising results. Recent advancements in ethylene study have revealed that ethylene is playing its role in a variety of vital physiological activities and metal stress tolerance in plants. The efficiency of endogenic ethylene level in plants beneath HM stress, based on our present understanding of ethylene and its regulatory actions, is thought to open the way for the growth and development of transgenic crops with enhanced HM tolerance in brassica. This research paper investigates ethylene synthesis and signal transduction in plant response to HM stress, as well as crosstalk between ethylene and other signaling molecules under extreme HM stress, and ways for modulating ethylene activity to advance HM resistance in brassica.
