Plant genes related to Phytophthora pathogens resistance

Abstract

Abstract Plants have evolved a multilayered and sophisticated immune system to establish effective resistance to a variety of pathogens. Phytophthora species are among the most notorious plant pathogens, causing destructive diseases on a variety of agricultural crops. Understanding the plant immune system is crucial for protecting crops from Phytophthora diseases. Here, we summarize the recent work on genes involved in plant resistance against Phytophthora pathogens, including cell surface pattern recognition receptors, cytoplasmic nucleotide-binding leucine-rich repeat receptors, regulator genes, and non-host resistance genes, small RNA, and long non-coding RNA are also discussed in this review. Although the molecular mechanisms of only a small proportion of them have been clarified, emergence of new mechanisms of plant defense will offer exciting opportunities for utilization of these genes in disease resistance breeding as well as generation of disease-resistant crop germplasms.
