Rice tungro disease is caused by an RNA and a DNA virus

Journal of General Virology, 1991
We present evidence that rice tungro spherical virus (RTSV) has a genome of polyadenylated single-stranded RNA of about 10 kb whereas rice tungro bacilliform virus (RTBV) contains double-stranded circular DNA. RTBV DNA has been mapped and shown to have two discontinuities, one in each strand, at specific sites; it thus resembles that of the ...

Characterization of the discontinuities in rice tungro bacilliform virus DNA

Journal of General Virology, 1992
The dsDNA of rice tungro bacilliform virus (RTBV) has two discontinuities, one on each strand, each in a specific position as found in other pararetroviruses. The 5' end of discontinuity 1 was mapped to nucleotide 1 of the published RTBV DNA sequence which suggests that tRNAiMet serves as a primer for negative strand DNA synthesis.

Single Nucleotide Polymorphisms in a Gene for Translation Initiation Factor (eIF4G) of Rice (Oryza sativa) Associated with Resistance to Rice tungro spherical virus

Molecular Plant-Microbe Interactions, 2010
Rice tungro disease (RTD) is a serious constraint to rice production in South and Southeast Asia. RTD is caused by Rice tungro spherical virus (RTSV) and Rice tungro bacilliform virus. Rice cv. Utri Merah is resistant to RTSV.

Suppression of Two Tungro Viruses in Rice by Separable Traits Originating from Cultivar Utri Merah

Molecular Plant-Microbe Interactions, 2009
Rice tungro disease (RTD) is caused by Rice tungro spherical virus (RTSV) and Rice tungro bacilliform virus (RTBV) transmitted by green leafhoppers. Rice cv. Utri Merah is highly resistant to RTD. To define the RTD resistance of Utri Merah, near-isogenic

Transforming rice production constraints into opportunities: Coordinated innovation for sustainable agrosystems in Asia

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Rice (Oryza sativa L.) production remains central to global food security, particularly across Asia, where both wetland and upland cultivation systems dominate. These agroecosystems face distinct ecological and agronomic constraints that threaten sustainable intensification.

Intelligent recognition algorithm for rice diseases in farmland based on multileaf segmentation

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Timely and accurate identification of specific types and development trends of rice (Oryza sativa L.) diseases in farmland is a critical prerequisite for implementing scientific control measures and reducing yield losses. Aiming at the problem of low recognition accuracy for rice diseases in farmland under natural lighting conditions, this ...
