| Abstract: | In China, the risk of cotton production on arable land contaminated with heavy metals has increased in recent years. Compared with other major crops, cotton shows stronger and widespread resistance to abiotic stresses such as heavy metals. As the main product of cotton is non-edible fibers, and cotton possesses a set of sophisticated stress-resistance strategies, cotton is an ideal crop for use in phytoremediation of soil contaminated by heavy metals. We present a global review of recent literature on the toxic effects of five heavy metals (cadmium, chromium, lead, arsenic, and mercury) at present in China and their effects on cotton, as well as summarize recent studies on the mechanisms of avoidance and avoidance both. We aim to provide insights into understanding the mechanisms of resistance to heavy metal stress in cottonunderstanding the relationship between cotton and heavy metal stress. |
