Project description:Mitogen-activated protein kinase kinase kinase (MAPKKK) assume a pivotal position within the MAPK cascade signaling pathway that converts external stimuli into intracellular responses, and plays a central role in adaptation and resistance to biotic and abiotic stress. Only a limited number of researches have reported that MAPKKK conducted on regulating the resistance to soybeans mosaic viruses (SMV). Here, we identified a MAPKKK 2-like gene named as GmMEKK2 from SMV resistance cultivar. Overexpression of GmMEKK2 in soybean not only reduced SMV content but also decreased the disease index of virus. Importantly, overexpression of GmMEKK2 mitigated the yield loss after SMV inoculation and improved the yield-related traits of soybean. These demonstrated that GmMEKK2 had a favorable role in SMV resistance. This study explored the functions of GmMEKK2 in soybean and provided an assertive solution for effectively improving SMV resistance.
Project description:Transcriptional changes in soybean plants infected with Soybean mosaic virus (SMV) was assessed at 7, 14 and 21 days post inoculation (dpi). Keywords: Time course
Project description:Virus Induced Gene Silencing (VIGS) was used to silence the expression of soybean Replication Protein 3 (GmRPA3). RNAseq was used to compare gene expression in GmRPA3 silenced and empty vector treated plants
Project description:RNA-seq was used to characterize gene expression in soybean from a wide range of tissues. The primary focus of the project was small RNAs, and the identification of microRNAs and phased siRNA-generating loci, but RNA-seq data were generated from the same samples. This project was supported by the United Soybean Board.
Project description:Chinese soybean (Glycine max (L.) Merr.) cultivars Rsmv1 and Ssmv1 were used for soybean mosaic virus (SMV) resistance genes screening. The Rsmv1 cultivar was highly-resistant to SMV but the Ssmv1 cultivar was highly-susceptible. We used microarrays to detail the global programme of gene expression underlying SMV inoculation and identified distinct expression genes between Rsmv1 and Ssmv1.
