Article alert: Dynamics of Southern rice black-streaked dwarf virus in rice and implication for virus acquisition
30.01.2013

Phytopathology (2013) doi: http://dx.doi.org/10.1094/PHYTO-10-12-0261-R

Matsukura K. et al.

A novel viral disease of rice caused by Southern rice black-streaked dwarf virus (SRBSDV) has spread throughout East and Southeast Asia since the mid-2000s. Outbreaks of this viral disease occur yearly in southern parts of Japan concurrently with overseas migration of the planthopper vector Sogatella furcifera from southern China during the rainy season (from late June to early July). We examined the dynamics (changes in titer and localization) of SRBSDV on rice using reverse transcription real-time PCR and determined the relationship between virus titer in plants and virus acquisition by S. furcifera. Under a constant temperature of 27C, a substantial increase of SRBSDV titer in the leaf sheath together with typical symptoms (stunted growth and twisting of leaf tips) was observed at 20 days after the end of a seven-day exposure of viruliferous S. furcifera. Approximately 40% of S. furcifera acquired SRBSDV through feeding for five days on rice plants that were infected following exposure to viruliferous vectors for 10-15 days. These results suggest that rice infected by S. furcifera can be a source of SRBSDV before the next generation of S. furcifera emerges.
