Agroinoculation of a full-length cDNA clone of cotton leafroll dwarf virus (CLRDV) results in systemic infection in cotton and the model plant Nicotiana benthamiana
Delfosse, Veronica Cecilia; Casse, Maria Florencia; Agrofoglio, Yamila Carla; Bonacic Kresic, Iván; Hopp, Horacio Esteban; Ziegler-Graff, Véronique; Distefano, Ana Julia (2013-07)Cotton blue disease is the most important viral disease of cotton in the southern part of South America. Its etiological agent, cotton leafroll dwarf virus (CLRDV), is specifically transmitted to host plants by the aphid ... -
Identification of a new cotton disease caused by an atypical cotton leafroll dwarf virus in Argentina
Agrofoglio, Yamila Carla; Delfosse, Veronica Cecilia; Casse, Maria Florencia; Hopp, Horacio Esteban; Bonacic Kresic, Iván; Distefano, Ana Julia (2017)An outbreak of a new disease occurred in cotton (Gossypium hirsutum) fields in northwest Argentina starting in the 2009–10 growing season and is still spreading steadily. The characteristic symptoms of the disease included ... -
P0 protein of cotton leafroll dwarf virus-atypical isolate is a weak RNA silencing suppressor and the avirulence determinant that breaks the cotton Cbd gene-based resistance
Agrofoglio, Yamila Carla; Delfosse, Veronica Cecilia; Casse, Maria Florencia; Hopp, Horacio Esteban; Bonacic Kresic, Iván; Ziegler-Graff, Véronique; Distefano, Ana Julia (Wiley, 2019-08)Cotton blue disease (CBD) is the most important disease present in cotton crops in South America and cotton leafroll dwarf virus (CLRDV) is the causal agent. The disease has been controlled by sowing cotton varieties ... -
The P0 protein encoded by cotton leafroll dwarf virus (CLRDV) inhibits local but not systemic RNA silencing
Delfosse, Veronica Cecilia; Agrofoglio, Yamila Carla; Casse, Maria Florencia; Bonacic Kresic, Iván; Hopp, Horacio Esteban; Ziegler-Graff, Véronique; Distefano, Ana Julia (2014-02)Plants employ RNA silencing as a natural defense mechanism against viruses. As a counter-defense, viruses encode silencing suppressor proteins (SSPs) that suppress RNA silencing. Most, but not all, the P0 proteins encoded ...
