Abstract

Rice (Oryza sativa L.), as one of the most important crops worldwide, has been widely adopted as a model for studying cereal crops and monocot plants. Rice production is severely threatened by pathogens and pests during the entire growth season, causing an estimated 10%–30% yield loss annually (Douglas, 2018; Savary et al., 2019). Therefore, disease and pest resistance has been one of the major goals in rice breeding. However, rice improvement has encountered a bottleneck largely due to the lack of useful disease resistance (R) genes and molecular approaches in breeding programs. Most R genes have limited application because of race-specificity. Therefore, the identification and application of novel R genes with broad-spectrum resistance have been a big challenge. Among many rice diseases, those causing the most relevant yield losses include the rice fungal blast caused by Magnaporthe oryzae (M. oryzae), bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo), sheath blight caused by the necrotrophic fungus Rhizoctonia solani (R. solani), false smut caused by the obligate biotrophic fungus Ustilaginoidea virens (Cke.) Tak (U. virens), and viral diseases including rice tungro virus and rice stripe virus. In addition, insect pests and plant parasitic nematodes have also caused huge yield loss of rice. Over the past 30 years, impressive advancements have been achieved in R gene discovery and molecular mechanisms of disease resistance and growth defense trade-offs (Deng et al., 2020; Li et al., 2020). These achievements have greatly facilitated the breeding of new disease and pest resistance cultivars. Within this specific topic on ‘Disease and Pest Resistance in Rice’, we aim to provide new knowledge on R gene discovery, mechanisms of rice immunity and resistance against pathogens and insects, and technology for rice improvement. Launched in Oct, 2021, this topic received 16 manuscripts in total and ultimately published 5 papers after peer-view, including four research articles and one review. We also regret that other submissions were not accepted for publication after reviewing.
