Abstract The risk of cotton production on arable land contaminated with heavy
metals has increased in recent years. Cotton shows stronger and more extensive
resistance to heavy metals, such as cadmium (Cd) than that of other major crops.
Here, a potted plant experiment was performed to study Cd-induced alterations in
the cottonseed kernel gossypol content and pigment gland structure at maturity in
two transgenic cotton cultivars (ZD-90 and SGK3) and an upland cotton standard
genotype (TM-1). The results showed that Cd accumulation in cottonseed kernels
increased with increasing Cd levels in the soil. The seed kernel Cd content in
plants grown… More >
