Project description:The occurrence of Tomato chlorosis virus (ToCV) disease seriously damages tomato growth and yield, and there is no effective way to control ToCV transmission. So far, no studies have reported exploring the interaction between ToCV and tomato at the single cellular level. In this study, single cell RNA sequence was performed on a total of 26720 individual cells from healthy and ToCV-infected tomato leaves. We through identifying cell types, the first tomato leaf cell atlas was successfully constructed. In situ hybridization experiments identified specific marker genes that can be used to identify tomato cell types. Moreover, we have characterized transcription factors that may play a key role in tomato response to ToCV infection, and described the trichome differentiation trajectory during ToCV infection through pseudotime analysis. In conclusion, we proved the feasibility of single-cell sequencing to study the response of plants to biotic stress, and put forward new insights into the interaction between ToCV and tomato from the cellular level. Our data will lay the foundation for following studies between ToCV and plants, and will also provide a valuable reference for future research on non-model plant single cells.

Project description:QTL-seq analysis for identification of resistance loci to bacterial canker in tomato

Project description:We constructed two independent small RNA libraries from leaves of mock and Cucumber mosaic virus (CMV) infected tomatoes, respectively, and sequenced with a high-throughput Illumina Solexa system. Based on sequence analysis and hairpin structure prediction, a total of 50 known miRNAs (32 families) and 568 potentially candidate miRNAs (PC-miRNAs) were firstly identified in tomato, with 12 known miRNAs and 154 PC-miRNAs supported by both the 3p and 5p strands. Comparative analysis revealed 79 miRNAs (including 15 novel tomato miRNAs) and 40 PC-miRNAs were differentially expressed between the two libraries. Among these virus responsive miRNAs, expression patters of some novel tomato miRNAs and PC-miRNAs in mock and in CMV-Fny infected tomatoes were further validated by qRT-PCR. Moreover, we revealed 563 potential targets for 66 tomato miRNAs by the recently developed degradome sequencing approach, including 124 targets for 7 new tomato miRNAs and 97 targets for 24 PC-miRNAs. Target annotation for the newly identified miRNA and PC-miRNAs indicated that they were involved in multiple biological processes, including transcriptional regulation and virus resistance. Gene ontology analysis of these target transcripts demonstrated that stress response- and photosynthesis-related genes were most affected in CMV-Fny infected tomatoes.

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.

Project description:Hybrid chlorosis, one of the hybrid incompatibilities, has frequently been reported in inter- and intraspecific crosses of allopolyploid wheat. In our previous study, hybrid chlorosis was observed in the wheat triploids between a tetraploid wheat cultivar Langdon and four Ae. tauschii accessions and in their derived synthetic hexaploids. However, the molecular mechanisms underlying hybrid chlorosis are not well understood. Here, we performed cytological and comparative gene expression analyses in leaves to characterize the abnormal growth in wheat synthetics showing mild and severe chlorosis symptom. In addition, disease resistance was comparatively assessed. A number of carbohydrate metabolism- and defense-related genes were markedly up-regulated in the hybrid chlorosis lines, and abnormal chloroplasts were formed in the mesophyll cells before the leaves turned to be yellowish. The mild chlorosis plants showed increased resistance to a wheat blast fungus, although little significant differences of agricultural traits were found between the wild-type and mild chlorosis-showing plants. These observations suggest that the senescence processes might be accelerated in the hybrid chlorosis lines of wheat synthetics. Moreover, the negative effects on biomass can be minimized and the substantial fitness may be obtained under pathogen-polluted conditions in the mild chlorosis-showing wheat synthetics. Expression patterns were compared between a wild-type synthetic wheat line (as a reference) and two hybrid chlorosis-showing hybrid chlorosis lines. Total RNA samples were isolated from the 3-week-old leaf tissues. Two independent experiments were conducted in each line.
