Transcriptome profiling of RNAi-trasgenic Solanum lycopersicum plants resistant to Tomato yellow leaf curl virus

ABSTRACT: RNA interference (RNAi) is a widely-used approach to generate virus-resistant transgenic crops. However, durability of RNAi-mediated resistance under extreme field conditions and side-effects of stable RNAi expression have not been thoroughly investigated. Here we performed field trials and molecular characterization of two RNAi-transgenic Solanum lycopersicum lines resistant to Tomato yellow leaf curl virus (TYLCV) disease, the major constraint for tomato cultivation in Cuba and worldwide. In order to determine potential impact of the hairpin RNA transgene expression on tomato genome expression and development, differences in the phenotypes and the transcriptome profiles between the transgenic and non-transgenic plants were examined. Transcriptome profiling revealed a common set of up- and down-regulated tomato genes, which correlated with slight developmental abnormalities in both transgenic lines.

Genome-wide miRNA and piRNA profiles of the vector whitefly, Bemisia tabaci during feeding on Tomato yellow leaf curl virus-infected tomato

Project description:The whitefly, Bemisia tabaci MEAM1 is a devastating vector capable of transmitting hundreds of plant viruses, including Tomato yellow leaf curl virus (TYLCV), to important food and fiber crops. Here we performed genome-wide profiling of micro RNAs (miRNAs) and piwi-interacting RNAs (piRNAs) in whiteflies after feeding on TYLCV-infected tomato or uninfected tomato for 24, 48 and 72 h. Overall, 160 miRNAs were discovered, 68 of which were conserved and 92 were B. tabaci-specific miRNAs. Majority of the genes that were predicted to be targeted by miRNAs had gene ontologies related to metabolic processes. We identified two miRNAs that were differentially expressed in whiteflies when fed on TYLCV-infected tomato compared to whiteflies that fed on uninfected tomato. The identified piRNAs were expressed as clusters throughout the whitefly genome. A total of 53 piRNA clusters were expressed across all time points and treatments, while 5 piRNA clusters were exclusively expressed in whiteflies that fed on TYLCV-infected tomato, and 24 clusters were exclusively expressed in whiteflies that fed on uninfected tomato. Approximately 62% of all identified piRNAs were derived from non-coding sequences that included intergenic regions, introns, and UTRs with unknown functions. The remaining 38% of piRNAs were derived from coding sequences (CDS) and repeat elements. Transposable elements targeted by piRNA clusters included both class I retrotransposons such as Gypsy, Copia, and LINEs and class II DNA transposons such as MITE, hAT, and TcMar. Lastly, six protein coding genes were targeted in whiteflies that fed on TYLCV-infected tomato. Information on how TYLCV influences miRNA and piRNA expression in whiteflies provides a greater understanding of regulatory pathways involved in mediating whitefly-virus interactions, and will facilitate the identification of novel targets for RNAi control.

Expression data in response to pepper leaf curl virus (PepLCV) infection in Chilli pepper at three leaf stage

Project description:A comparative study to determine the pepper leaf curl virus resistance machanism between resistant and susceptible genotypes at three leaf stage. To study the molecular mechanism of pepper leaf curl virus (PepLCV) resistance, pepper plants were exposed to PepLCV through artificial inoculation and hybridization on Agilent tomato microarrays. The expression analysis of PepLCV resistant and susceptible genotypes after artificial inoculation at three leaf stage showed that the resistance against PepLCV is due to sum of expression of hundreds of genes at a particular stage. Tomato microarrays consisting of 43,803 probes were used for whole genome expression analysis of chilli peppers for resistance against PepLCV. Transcripts from the leaves of resistant (BS-35) and susceptible plants (IVPBC-535) were compared in response to PepLCV inoculation at three leaf stage.

Expression analysis of tomato plants TYLCV resistant, susceptible and resistant line silenced in the hexose transporter (LeHT1) gene before and 7 days after inoculation of tomato with Tomato yellow leaf curl virus (TYLCV).

Project description:Investigation of whole genome gene expression level changes in a resistance susceptible and LeHT1-silenced resistance tomato plants, infected with TYLCV and compared to the non infected control. Two inbred tomato lines (named R and S) were used issued from a breeding program describe by Vidavsky and Czosnek, 1998, and Silencing of the hexose transporter gene LeHT1 and the properties of these plants have been described by Eybishtz et al., 2010. The array was designed to include all the known tomato genes retrieved from TIGR and Sol Genomics public databases. Following filtration for redundancies, 25,591 known genes and 7,335 uncertain or unknown genes were retrieved The data were transferred to Roche NimblGen company (http://www.nimblegen.com/) who has generated a 60-mer oligonucleotide array where each of the ~30,000 tomato genes is represented by at least two specific probes, and unrelated controls. Each slide contains four arrays of ~70,000 oligos. TYLCV resistant and susceptible lines infection with TYLCV and LeHT1 silenced TYLCV resistant line infected with TYLCV
