Project description:To explore the molecular basis of validamycin overproduction at the transcriptional level, the transcriptomes of strain 5008 and TL01 cultivated in Yeast extract-Malt extract-Glucose (YMG) and rice-peanut cake based industrial (IND) fermentation medium were compared by microarray analysis. Global gene expressions in the strain 5008 and TL01 were measured in fermentation medium YMG and IND, respectively. Three independent experiments were performed at each condition.

Project description:Small ruminant morbillivirus (SRMV), formerly named Peste-des-petits ruminanats virus (PPRV), belongs to the genus Morbillivirus genus in the family Paramyxoviridae and leads to a highly contagious disease in small ruminants, especially goats and sheep. Lysine succinylation is a newly identified and conserved modification and plays important roles in host cells response to pathogen infection. Herein, we present the comprehensive analysis of the succinylome of SRMV-infected Vero cell using quantitative proteomics. Overall, we identified 875 succinylated proteins with 2840 succinylation sites. Comparative analysis revealed that 139 down-regulated succinylated proteins with 228 succinylation sites and 38 up-regulated succinylated proteins with 44 succinylation sites were significant succinylated in response to SRMV infection, seven lysine succinylation motifs were identified. Bioinformatics analysis showed that the succinalated proteins mainly participated in in cellular respiration and biosynthetic process. Protein-protein interaction networks of the identified proteins provided further evidence that a variety of ATP synthase subunits and carbon metabolism were modulated by succinylation, the overlapped proteins between succinylation and acetylation are involved in glyoxylate and dicarboxylate metabolism. In summary, this is the first study of the succinylome in SRMV infection, lysine acetylation may have a more important effect than succinylation in PPRV infection. It provides a novel view on investigating the infection mechanism of SRMV.
Project description:Fruit dehiscence is an essential developmental process of some economic crops that impacts dramatically on crop yields and involves altered regulation of thousands of genes, ind-6 gene is a transcription factor play important role during fruit dehiscence. Gene expression were examined in wild-type and ind-6 mutants at three development stages of fruit dehiscence to explore the molecular mechanism of ind-6 in fruit dehiscence. We used microarrays to examine changes in gene expression during fruit dehiscence and identified distinct classes of up- and down-regulated genes in wild-type and ind-6 mutant genotypes.
Project description:rs10-03_ind - comparison of ind induced vs mock treated seedlings - Identification of miRNAs regulated by IND - Transgenic seeds containing an IND transgene under the control of a dexamethasone inducible promoter were germinated and grown in liquid Murashige/Skoog medium under a 16h light/8h darkness light regime. After seven days of growth, seedlings were either mock-treated or treated with 10 micromolar dexamethasone for 24 hours.
