Emergence of Southern Rice Black Streak Dwarf Virus in Sugarcane and Jungle Rice Reveals New Alternate Hosts
A field survey conducted in Ambala District, Haryana, India, during the 2025 rice-growing season revealed the presence of southern rice black streak dwarf virus (SRBSDV) in stunted rice plants. RT-PCR detection across multiple crop stages (June–October) confirmed SRBSDV infection in 18 of 22 rice samples, as well as in adjacent non-rice hosts, including 6 of 7 sugarcane (Saccharum officinarum) and 4 of 6 jungle rice (Echinochloa colona) samples, while all pigweed samples (0/6) tested negative. The consistent detection of SRBSDV in these Poaceae species indicates active circulation of the virus beyond rice. To the best of our knowledge, this study provides the first evidence of SRBSDV detection in sugarcane and Echinochloa colona, demonstrating an expanded host range and suggesting their potential roles as alternate or reservoir hosts that may facilitate virus persistence and early-season reintroduction into rice ecosystems.
期刊介绍：
Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays.
Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes.
Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
