Nicotiana benthamiana is a potential host to several plant pathogens, and immature leaves of N. benthamiana are susceptible to Phytophthora infestans. In contrast, mature leaves of N. benthamiana are weakly susceptible and show basal resistance to P. infestans. We screened a gene-silenced mature plant showing high resistance to P. infestans, designated as DS2 (Disease suppression 2). The deduce...
Active oxygen species (AOS) are central components of the defence reactions of plants against pathogens. Plant respiratory burst oxidase homologues (RBOH) of gp91(phox), a plasma membrane protein of the neutrophil nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, play a prominent role in AOS production. The role of two RBOH from Nicotiana benthamiana, NbrbohA and NbrbohB that encode ...
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 both hosts, but a different size profile was observed, with an abundance peak at 21 in N. bentham...
Plant pathogenic oomycetes, such as Phytophthora sojae, secrete an arsenal of host cytoplasmic effectors to promote infection. We have shown previously that P. sojae PsCRN63 (for crinkling- and necrosis-inducing proteins) induces programmed cell death (PCD) while PsCRN115 blocks PCD in planta; however, they are jointly required for full pathogenesis. Here, we find that PsCRN63 alone or PsCRN63 ...
An isolate of chilli veinal mottle virus (ChiVMV; genus Potyvirus) Solanum nigrum L. from southwest China (ChiVMV-YunN/Yuxi) was identified and sequenced (GenBank: OP404087). Comparison with other ChiVMV isolates recombination analyses suggested a recombinant origin. The most significant event among all 21 complete an ending breakpoint at 1408–1488 for ChiVMV-YunN/Yuxi ChiVMV-TaiW ChiVMV-YunN/C...
Abstract Tomato brown rugose fruit virus (ToBRFV) is a new member of the genus Tobamovirus , and has potential to affect production marketability tomatoes peppers. In this study, we sequenced analyzed complete genome ToBRFV isolates from tomato plants showing mosaic mottling symptoms in Yunnan Province China. We constructed full-length infectious cDNA clone ToBRFV, which could induce systemic i...
