Viral small RNAs (vsRNAs) are one of the key elements involved in RNA silencing-based defense against viruses in plants. We analyzed the vsRNA profiles in Nicotiana benthamiana and Solanum lycopersicum infected by polygonum ringspot virus (PolRSV) (Tospovirus, Bunyaviridae). VsRNAs were abundant in
The sesquiterpenoid polygodial, which belongs to the drimane family, has been shown to be an antifeedant for a number of herbivorous insects. It is presumed to be synthesized from farnesyl diphosphate via drimenol, subsequent C-12 hydroxylation and further oxidations at both C-11 and C-12 to form a
Tomato (Lycopersicon esculentum Mill.) plants showing severe chlorotic and necrotic ringspots, line patterns on leaves, and concentric chlorotic ringspots on stems and fruits were observed in plastic greenhouse-grown tomato crops cv. Royesta during the spring of 1996 in Zaragoza province, Northeast
