Abstract
Rice is one of the most important staple food crops, which feeds more than half of
the world’s population. Rice blast disease, caused by Magnaporthe oryzae, is one
of the major factors affecting rice yield negatively. Several epidemics of rice blast
disease have been reported across the globe which results in the loss of up to
100% of the total rice production in the region. Development and use of diseaseresistant cultivars is the most effective and environment-friendly method for the
control of this deadly disease. Therefore, several lines of studies have been
carried out to understand the molecular mechanism of rice-M. oryzae interaction.
Being the first line of defense, numerous studies were performed on pathogenassociated molecular patterns (PAMPs) and effectors in M. oryzae, as well as
plasma membrane-localized and cytosolic receptors, which contribute to rice
blast resistance by activation of PAMP-triggered immunity (PTI) and effectortriggered immunity (ETI). In this chapter, we briefly summarize the progress
made so far in the PTI and ETI signaling networks including downstream cellular
and physiological responses in rice–M. oryzae pathosystem.
