Abstract:The economic importance of tomato is well documented, and tomato has become a model for fleshy fruit development and ripening studies. Plant microRNAs (miRNAs) are small endogenous RNAs that are involved in a variety of activities, including plant development, signal transduction and protein degradation, as well as response to environment stress, and pathogen invasion. Here in this study, we aimed at quantifying the expression alterations of nine miRNAs and target mRNAs in tomato flower and fruit development upon CMV and TAV infections. Three different Cucumber mosaic virus (CMV) strains CMV-Fny, CMV-Fny2b, CMV-Fny-satT1 and Tomato aspermy virus (TAV)-Bj were used in our investigation, and the miRNA/mRNA expression alterations were analyzed by real-time quantitative RT-PCR. The results shown the levels of several miRNA/mRNA pairs were increased upon virus infection. However, the increased levels of individual miRNAs differed for different virus strains, reflecting differences in severity of symptom phenotypes. The altered expression pattern of these miRNA/mRNA pairs and their predicted functions indicate the possible roles in flower and fruit development, and provide experimental data for understanding the miRNA-mediated phenotype alterations in tomato fruit. | |||

Abstract:Cucumber mosaic virus (CMV) and Tomato mosaic virus (ToMV) are two principal viruses infecting tomato (Lycopersicon esculentum Mill). N5 is a necrosis strain of ToMV. In this work, interference between these two virues was analyzed in tomato cv. Hezuo 903. Plants were first inoculated with CMV-Fny or CMV-Fny∆2b, respectively. 7 days postinoculation (dpi), a second challenge inoculation was performed with ToMV-N5. The results showed that plants can be protected against challenge with ToMV-N5 by initial CMV-Fny infection, but not by CMV-Fny2b. The accumulation of these three viruses in single and double infections was detected by real-time reverse transcription-polymerase chain reaction (real-time RT-PCR) assays. The real-time RT-PCR values indicated that ToMV-N5 accumulation was significantly suppressed by double infection with CMV-Fny in the second true leaves. The interaction between PVX and ToMV was further studied. The host reaction of PVX-BJ and ToMV-N5 double infections was almost the same as in ToMV-N5 singly infections. Based on above results, we speculate that the 2b protein may be an important determinant involved in CMV-mediated regulation of disease development caused by ToMV-N5 in tomato cv. Hezuo 903. | |||
