Physiological, anatomical, and molecular responses of glanded and glandless cotton to chromium exposure.

ABSTRACT: Cotton seeds are a major source of high-quality proteins and edible oil, but their utilization is limited due to gossypol toxicity to humans and animals. For better use of cotton as food and feed, several glandless cotton cultivars have been developed, which are susceptible to various biotic stresses. However, their resistance to abiotic stresses, i.e., heavy metals, has rarely been studied. In the current study, the effect of different doses of chromium (Cr)-0, 10, 50, and 100 μM-on the physiological, anatomical, and molecular aspects of cotton was investigated. Genotypic variation exists in the response of cotton to Cr stress. Current results revealed that Cr caused inhibition in leaf biomass and ultrastructure damage, showing large intercellular spaces, thick cell walls, distorted nucle
