Physical interaction of RTBV ORFI with D1 protein of Oryza sativa and Fe/Zn homeostasis play a key role in symptoms development during rice tungro disease to facilitate the insect mediated virus transmission.

Rice tungro disease is caused by the combined action of Rice tungro bacilliform virus (RTBV) and Rice tungro spherical virus (RTSV). The RTBV is involved in the development of symptoms while RTSV is essential for virus transmission. We attempted to study the mode of action of RTBV in the development of symptoms.
