Abstract：
Cadmium (Cd) is a heavy metal highly toxic to living organisms. Cd pollution of soils has become a serious problem worldwide, posing a severe threat to crop production and human health. When plants are poisoned by Cd, their growth and development are inhibited, chloroplasts are severely damaged, and respiration and photosynthesis are negatively affected. Therefore, elucidating the molecular mechanisms that underlie Cd tolerance in plants is important. Transcription factors can bind to specific plant cis-acting genes. Transcription factors are frequently reported to be involved in various signaling pathways involved in plant growth and development. Their role in the resistance to environmental stress factors, particularly Cd, should not be underestimated. The roles of several transcription factor families in the regulation of plant resistance to Cd stress have been widely demonstrated. In this review, we summarize the mechanisms of five major transcription factor families-WRKY, ERF, MYB, bHLH, and bZIP-in plant resistance to Cd stress to provide useful information for using molecular techniques to solve Cd pollution problems in the future.
摘要：
镉（Cd）是一种对生物体剧毒的重金属。土壤Cd污染已成为世界范围内的严重问题,对作物生产和人类健康构成严重威胁。当植物被Cd毒害时，他们的生长发育受到抑制，叶绿体严重受损,呼吸和光合作用受到负面影响。因此,阐明植物对Cd耐受性的分子机制很重要。转录因子可以与特定的植物顺式作用基因结合。经常报道转录因子参与涉及植物生长和发育的各种信号通路。它们在抵抗环境压力因素中的作用，特别是Cd,不应该被低估。多个转录因子家族在调控植物对Cd胁迫的抗性中的作用已被广泛证明。在这次审查中,我们总结了五个主要的转录因子家族-WRKY，ERF,MYB,bHLH,和bZIP-in植物对Cd胁迫的抗性，为将来使用分子技术解决Cd污染问题提供有用的信息。
