Project description:We used wheat as rotational crop to assess the influence of continuous cropping on microbiome in Pinellia ternata rhizosphere and the remediation of rotational cropping to the impacted microbiota. Illumina high-throughput sequencing technology was utilized for this method to explore the rhizosphere microbial structure and diversity based on continuous and rotational cropping.

Project description:Soybean (Glycine max) is susceptible to root rot when subjected to continuous cropping, and this disease can seriously diminish the crop yield. Herein, isobaric tag for relative and absolute quantitation (iTRAQ) labeling and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were employed for proteomic analysis of continuously cropped soybean inoculated with the arbuscular mycorrhizal (AM) fungus Funneliformis mosseae. Differential expression of proteins in soybean roots was determined following 1 year of continuous cropping. A total of 131 differentially expressed proteins (DEPs) were identified in F. mosseae-treated samples, of which 49 and 82 were up- and down-regulated, respectively. The DEPs were annotated with 117 Gene Ontology (GO) terms, with 48 involved in biological processes, 31 linked to molecular functions, and 39 associated with cell components. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis mapped the DEPs to 113 mainly metabolic pathways including oxidative phosphorylation, glycolysis and amino acid metabolism. Expression of glucan 1,3-beta-glucosidase, chalcone isomerase, calcium-dependent phospholipid binding and other defense-related proteins was up-regulated by F. mosseae, suggesting inoculation promotes the growth and development of soybean and increases disease resistance. The findings provide an experimental basis for further research on the molecular mechanisms of AM fungi in resolving problems associated with continuous soybean cropping.

Project description:Panax ginseng C.A. Meyer is a precious Chinese herbal medicine belonging to the Araliaceae family. Because ginseng is extremely taboo, it seriously restricts the sustainable development of the ginseng industry. The allelopathic effect of triterpenoid saponins is one of the important incentives for continuous cropping disorders. However, there are few studies on the mechanism of allelopathic autotoxicity of triterpenoid ginsenosides. Therefore, this study took ginseng hairy roots as the research object, exogenously added ginsenoside Ro to regulate the growth of hairy roots, and measured the changes in its physiological and saponin content. It was found that ginseng hairy roots grew significantly under Ro-0.5 mg/L stress. Inhibition, the specificity of root tip cell injury was obvious, promoted the accumulation of endogenous hormones IAA and SA, and inhibited the accumulation of ABA and JA. The accumulation of ginsenosides was significantly inhibited (except Rg3) under Ro-0.5 mg/L stress. The mRNA analysis of the Ro-0.5 mg/L group and CK group showed that the differentially expressed genes were mostly concentrated in the hormone signal transduction pathway. The genes ARF7 and EFM were up-regulated, and XTH23 and ZOX1 were down-regulated, which can be used as important candidates for hormone-responsive continuous cropping disorders. Gene. 74 differentially expressed miRNAs were identified based on miRNA sequencing, of which 22 were up-regulated and 52 were down-regulated. The target genes of ptc-miR156k_L+1, mtr-miR156b-5p, gma-miR156a_R+1, and mtr-miR156e were all TRINITY_DN14567_c0_g4, TRINITY_DN14567_c0_g4 is a gene in the plant hormone signal transduction pathway, and the four miRNAs are all negatively correlated with mRNA, indicating that ptc-miR156k_L+1, mtr-miR156b-5p, gma-miR156a_R+1, and mtr-miR156e are very likely involved in ginseng Response to continuous cropping disorders and regulation of ginsenoside synthesis. Our findings will provide a useful platform for unraveling the continuous cropping barrier of ginseng and new insights into the genetic engineering of plant stress responses.
