The Role of Non-Coding RNA in Rice Immunity

Abstract

Disease has been a major concern in the rice-growing sector, resulting in significant losses and compromised food security. To combat disease, plants have devised various defense strategies. Initial works in understanding plant–pathogen interactions were focused on discovering resistance and pathogenicity genes, as well as analyzing the functions of these genes in the host defense. Later, researchers discovered that regulatory elements, such as transcription factors, were essential players in modulating plant defenses. As the depth of research and knowledge in this field increased, non-coding RNA (ncRNA) were discovered to play key functions in plant immunity. In this review, we explore the contribution and interaction of microRNAs (miRNAs), long ncRNAs (lncRNAs), and small interfering RNAs (siRNAs) in controlling the rice immune response. The role and the interaction between ncRNAs and their targets have been discussed in detail. We believe that this information will be beneficial in disease resistance breeding of rice.
