Fungal and Oomycete Diseases

Fungal and oomycete pathogens are the causal agents of many important plant diseases. They affect crops that are staple foods for humans and livestock and are responsible for significant economic losses every year. This in turn generates a global social impact. Although fungi and oomycetes evolved separately, they share similar strategies and weaponry to attack plants. Here we review the challenges to global food security posed by these pathogens, current technologies used for detection and diagnostics, the latest understanding of pathogens' strategies to colonize plants, and current and future control measures. Genomic sequences of several important fungal and oomycete pathogens, as well as many crop plants, are now available and are helping to increase understanding of host–pathogen interactions. Recent developments in this field are discussed.
