Viruses of the genus Begomovirus (family Geminiviridae) have genomes consisting of either one or two genomic components. High-throughput sequencing of small RNAs allowed the identification of a novel DNA virus in a Chinese mulberry tree affected by a disease showing mosaic and dwarfing symptoms. [2] Background Cassava mosaic disease (CMD) is a major constraint on cassava cultivation in Africa. Begomoviruses are single-stranded DNA plant viruses transmitted by whiteflies of the Bemisia tabaci complex and are considered one of the most important groups of emerging plant viruses in tropical and subtropical regions. The whitefly vector Bemisia tabaci (Genn. The names tomato golden net virus (ToGNV) and tomato yellow net virus (ToYNV) were proposed. In this pathway, a protein containing a classical basic nuclear localization signal (NLS) is imported by a heterodimeric import receptor consisting of the β -karyopherin importin β, which mediates. This NLS-dependent protein recognition, a process necessary for cargo proteins to pass the nuclear envelope through the nuclear pore complex, is facilitated by members of the importin superfamily. NAC (NAM, ATAF1,2, and CUC2) transcription factors are one of the largest transcription factor families found in the plants and are involved in diverse developmental and signalling events. Background Tomato leaf curl viruses, which are the members of the genus Begomovirus, have emerged as devastating pathogens worldwide causing huge economic losses and threatening production of crops like cassava, cotton, grain legumes and vegetables. The βC1 protein encoded by betasatellites is multifunctional. 1016/s0168-1702 (01)00363-x. Section snippets Expression of truncated mouse importin-α, crystallization and structure determination. Multipartite viruses have one of the most puzzling genetic organizations found in living organisms. Begomovirus is the largest genus of the geminiviruses, having more than 400 species. Nuclear localization signals (NLS) are generally short peptides that act as a signal fragment that mediates the transport of proteins from the cytoplasm into the nucleus. The fast-paced evolution of viruses enables them to quickly adapt to the organisms they infect by constantly exploring the potential functional landscape of the proteins encoded in their genomes. A novel cytorhabdovirus, tentatively named “paper mulberry mosaic-associated virus” (PMuMaV), was discovered and identified by transcriptome sequencing (RNA-seq), small RNA sequencing (sRNA-seq), and RT-PCR amplification. [1] An advantage of multipartite genome is its ability to synthesize multiple mRNA strands to. RNA viruses may be monopartite (all genes on one strand), multipartite (two or more strands packaged separately) or segmented (two or more strands packaged together). Analysis of two obtained full-length viral genome sequences showed that they shared 99. Background. Geminiviruses constitute one of the largest groups of plant viruses, having characteristic twinned geminate particles encapsidating small circular single-stranded DNA molecules. . Summary.

Non-cultivated weeds have been reported to act as natural virus reservoirs. ca. True automation is here. Geminivirus-encoded proteins are traditionally identified by applying a 10-kDa arbitrary threshold; however, it is increasingly clear. Geminiviruses, DNA viruses infecting plants and causing devastating crop diseases worldwide, produce a limited number of multifunctional proteins that mediate the manipulation of the cellular. These viruses have several genome segments, each containing only a part of the genetic information, and each individually encapsidated into a separate virus particle. The pathologic effects of viral diseases result from (a) toxic effect of viral genes products on the metabolism of infected cells, (b) reactions of the host to infected cells expressing virus genes, and (c) modifications of cellular functions by the interaction of cellular DNA or proteins with viral gene products (see chapter 44. Even though the ToLCV isolates from Northern India have been shown to possess bipartite genome (designated as DNA A and DNA B), those from. To determine the structural basis of the recognition of the two classes of NLSs by m.
