Characterization of a Begomovirus-Betasatellite Complex, Producing Defective Molecules in Spinach (Spinacia oleracea L.), a New Host for Begomovirus and Betasatellite Complex in Pakistan
Spinach is a vegetable crop which is widely grown over a large area especially in Punjab province of Pakistan. Leaf curling and enations on spinach plant collected shown to be associated with the begomovirus Pedilanthus leaf curl virus (PeLCV) and Shahdadpur strain of Cotton leaf curl Multan betasatellite (CLCuMBSha). Defective molecules of half and quarter size derived from monopartite begomov...
متن کاملAn unusual alphasatellite associated with monopartite begomoviruses attenuates symptoms and reduces betasatellite accumulation.
The Oman strain of Tomato yellow leaf curl virus (TYLCV-OM) and its associated betasatellite, an isolate of Tomato leaf curl betasatellite (ToLCB), were previously reported from Oman. Here we report the isolation of a second, previously undescribed, begomovirus [Tomato leaf curl Oman virus (ToLCOMV)] and an alphasatellite from that same plant sample. This alphasatellite is closely related (90 %...
متن کاملGenome-Wide Characterization of miRNAs Involved in N Gene-Mediated Immunity in Response to Tobacco Mosaic Virus in Nicotiana benthamiana
microRNAs (miRNAs) are a class of endogenous small RNAs (sRNAs) that play pivotal roles in plant development, abiotic stress response, and pathogen response. miRNAs have been extensively studied in plants, but rarely in Nicotiana benthamiana, despite its wide use in plant virology studies, particularly for studying N protein-tobacco mosaic virus (TMV) interactions. We report an efficient method...
متن کاملCharacterization of Small Interfering RNAs Derived from the Geminivirus/Betasatellite Complex Using Deep Sequencing
BACKGROUND Small RNA (sRNA)-guided RNA silencing is a critical antiviral defense mechanism employed by a variety of eukaryotic organisms. Although the induction of RNA silencing by bipartite and monopartite begomoviruses has been described in plants, the nature of begomovirus/betasatellite complexes remains undefined. METHODOLOGY/PRINCIPAL FINDINGS Solanum lycopersicum plant leaves systemical...
متن کاملMembers of the XB3 Family from Diverse Plant Species Induce Programmed Cell Death in Nicotiana benthamiana
Programmed cell death has been associated with plant immunity and senescence. The receptor kinase XA21 confers resistance to bacterial blight disease of rice (Oryza sativa) caused by Xanthomonas oryzae pv. oryzae (Xoo). Here we show that the XA21 binding protein 3 (XB3) is capable of inducing cell death when overexpressed in Nicotiana benthamiana. XB3 is a RING finger-containing E3 ubiquitin li...
