Cadmium (Cd): An Emerging Regulatory Metal with Critical Role in Cell Signalling and Plant Morphogenesis

Renata Bączek-Kwinta

Abstract

Cadmium is a toxic metal whose contamination in the environment has resulted from various industrial and agricultural activities like coal combustion, nickel-cadmium batteries, fluorescent paints, fertilisers, etc. Cadmium toxicity to plants leads to various anatomical, physiological and biochemical changes. Plants show retarded growth and productivity. However, there are certain unique examples of cadmium playing the role of essential metal like zinc in a diatom. It is also considered that cadmium accumulation by plants acts as a deterrent for insects and therefore protects plants from herbivory. The emerging evidences suggest that cadmium affects important regulatory functions in plants and brings about changes in plant phenotype and growth. A number of factors take part in signalling of cadmium stress. These include reactive oxygen and nitrogen species; hormones like jasmonic acid, brassinosteroids, salicylic acid, ethylene, etc.; and microRNAs. This chapter discusses toxic and regulatory functions of cadmium in plants with an emphasis on cadmium signalling mechanisms.
