Abstract:

Plants have evolved a complex immune system which helps them cope with pathogen attacks. The hypersensitive reaction is one of the various defense mechanisms which is characterized by a rapid cell death at the point of pathogen ingress, hence restricting the spread of the invading pathogens from the infection sites. Hypersensitive induced reaction proteins are a group of proteins involved in hypersensitive reaction, playing an important role in plant immunity. Hypersensitive induced reaction proteins contain highly conserved SPFH domain, which is thought to be related to the formation of membrane microdomains. In recent years, studies have shown that hypersensitive induced reaction proteins play an important role in regulation of anthocyanin biosynthesis and participate in ion transportation as well as abiotic stress resistance. The review discribes the research history, structural features and cellular locations, and biological functions of hypersensitive induced reaction proteins, and propose the future research directions.
