Nicotiana tabacum degradome analysis using high definition adapters proves an efficient targeting method against the Tomato leaf curl New Delhi virus using artificial ta-siRNAs [PARE]

Project description:RNA interference (RNAi) is a conserved, RNA-mediated, regulatory mechanism in eukaryotes. In plants, it plays an important role in growth, development and resistance against viral infections. As a counter-defence, plant viruses, e.g. geminiviruses, encode RNAi suppressors, such as AC2, AC4 and AV2. To obtain Nicotiana tabacum virus resistant plants against Tomato leaf curl New Delhi virus (ToLCNDV), we employ the biogenesis pathway of a class of endogenous siRNAs, the trans-acting siRNAs (ta-siRNAs), by engineering artificial ta-siRNAs (ata-siRNAs) targeting the AC2 (TRiV-AC2) and AC4 (TRiV-AC4) RNAi suppressors using miRNA390 dual target sites. The mode of action of ta-siRNAs comprises of the cleavage of the target (similar to the miRNA targeting). Using degradome approaches, the abundance of the resulting 3' fragment of the cleaved transcript can be quantified and the precise localization of the cleavage on the target mRNA can be identified. We sequenced degradome libraries of Nicotiana tabacum plants infected with ToLCNDV which were treated with the ata-siRNA-AC2 construct; mock-treated plants were used as controls. Following quality checks, the abundance distributions of the degradation fragments were normalized. The transcripts with different cleavage patterns was the AC2, supporting the conclusion that an efficient cleavage of the target occurred, without significant off-target effects.

Detection of ToLCNDV resistance in cucumber through agroinoculation under controlled condition

Project description:In this study, Agrobacterium tumefaciens containing recombinant plasmids were used to agroinoculate cucumber seedlings with tandem repeats of DNA-A genome of Tomato leaf curl New Delhi virus (ToLCNDV). The inoculated seedlings, representing both resistant and susceptible accessions, were monitored for symptoms over a period of four weeks. Symptom development was observed in susceptible genotypes, while the resistant genotype remained symptomless. Leaf samples were collected from both agroinoculated and control plants for further analysis. This research sheds light on the pathogenicity of ToLCNDV in cucumber and highlights the potential resistance mechanisms in certain accessions.

Global Analysis of the Transcriptional Response of Whitefly to Tomato Yellow Leaf Curl China Virus (TYLCCNV)

Project description:We investigated the transcriptional response of invasive B. tabaci B biotype to tomato yellow leaf curl China virus (TYLCCNV) using Illumina sequencing technology. We found that 1,606 genes involved in 157 biochemical pathways were differentially expressed in the viruliferous whiteflies.

Maintenance of Cotton Leaf Curl Multan Betasatellite by Tomato Leaf Curl New Delhi Virus-Analysis by Mutation.

Project description:Viruses of the genus Begomovirus (family Geminiviridae) are economically important phytopathogens that are transmitted plant-to-plant by the whitefly Bemisia tabaci. Most Old World (OW) begomoviruses are monopartite and many of these interact with symptoms and host range determining betasatellites. Tomato leaf curl New Delhi virus (ToLCNDV) is one of only a few OW begomoviruses with a bipartite genome (components known as DNA A and DNA B). Four genes [AV2, coat protein (CP), transcriptional-activator protein (TrAP), and AC4] of ToLCNDV were mutated and the effects of the mutations on infectivity, symptoms and the ability to maintain Cotton leaf curl Multan betasatellite (CLCuMuB) were investigated. Infectivity and virus/betasatellite DNA titer were assessed by Southern blot hybridization, PCR, and quantitative PCR. The results showed TrAP of ToLCNDV to be essential for maintenance of CLCuMuB and AV2 to be important only in the presence of the DNA B. AC4 was found to be important for the maintenance of CLCuMuB in the presence of, but indispensable in the absence of, the DNA B. Rather than being required for maintenance, the CP was shown to possibly interfere with maintenance of the betasatellite. The findings show that the interaction between a bipartite begomovirus and a betasatellite is more complex than just trans-replication. Clearly, multiple levels of interactions are present and such associations can cause additional significant losses to crops although the interaction may not be stable.
