Genomics and transgenic approaches for sheath blight resistance development in rice

Abstract

Among the most devastating fungal diseases, rice sheath blight is brought on by Rhizoctonia solani Kühn (Teleomorph: Thanatephorus cucumeris), and it significantly reduces rice grain output. Since there are no dependable resistance genes and nothing is known about the biology of the disease, rice sheath blight continues to be a significant global problem. Presently, fungicides are most frequently used to treat rice sheath blight. However, they harm the environment and are not advised. Genomics and transgenic approaches show promise for sheath blight control by identifying key insight genes and developing the host resistance plants. This review emphasizes comprehending the genetics underlying host-pathogen interactions, identifying gene loci/markers, and designing a transgenic host genome.
