Abstract
ABSTRACT The plant hormone abscisic acid (ABA) has been proved to be a key protector against abiotic stresses at appropriate concentrations. This study aimed to investigate the role of ABA in alleviating cadmium (Cd) stress in two Brassica napus of oil-vegetable dual-purpose (Youfei 1 and Xiangyou 787). Cd stress disturbed the normal growth of rapeseed, however, specific ABA concentrations could alleviate the effects of Cd stress in B. napus. The results confirmed that exogenous ABA mitigates the negative effects of Cd-induced plant toxicity in B. napus by increasing growth traits, enhancing pigment molecules, enhancing gas exchange in leaves, as well as regulating antioxidation and the expression levels of genes related to Cd stress. This study indicated that ABA played an important protective role in regulating cadmium resistance in Brassica napus, and provided basic data for its application in actual production.
期刊介绍:
Environmental Pollutants & Bioavailability is a peer-reviewed open access forum for insights on the chemical aspects of pollutants in the environment and biota, and their impacts on the uptake of the substances by living organisms.
Topics include the occurrence, distribution, transport, transformation, transfer, fate, and effects of environmental pollutants, as well as their impact on living organisms. Substances of interests include heavy metals, persistent organic pollutants, and emerging contaminants, such as engineered nanomaterials, as well as pharmaceuticals and personal-care products as pollutants.
