Web31. mar 2024 · RTD is caused by the interaction between Rice tungro spherical virus (RTSV) and Rice tungro bacilliform virus. RTSV resistance found in traditional cultivars has contributed to a reduction in the incidence of RTD in the field. Natural RTSV resistance is a recessive trait controlled by the translation initiation factor 4 gamma gene (eIF4G). WebViruses come in many different shapes and sizes, but all are made of two essential components: a core of genetic material, either DNA or RNA, which is surrounded by a protective protein coat called a capsid. Packaged together, a single virion comes in four different shapes: helical, polyhedral, spherical, and complex.
