Project description:Purpose: The goal of this study are to reveal the internal mechanism of Bacillus cereus G2 increased Glycyrrhiza uralensis Fisch. seedlings salt-tolerance by RNA-Seq. Methods: mRNA profiles of Glycyrrhiza uralensis Fisch. Seedling in four treatment: control treatment, G2 treatment, salt treatment, salt and G2 treatment. Results: We mapped about 3 million sequence reads per sample to the G. uralensis transcriptome. A total of 35,831 genes in all samples of G. uralensis were identified and quantified by transcriptions, among which 3608 DEGs were identified. There are 1589, 623, 469 and 927 DEGs in S vs CK, CK+B vs CK, S+B vs S and S+B vs CK+B comparisons, respectively. Validation of expression levels for 12 randomly selected DEG candidates was carried out by quantitative real-time PCR (qRT-PCR). The results showed high congruence between RNA-Seq and qRT-PCR results (coefficient of determination R2 =0.9088) indicating the reliability of RNA-Seq quantification of gene expression. Conclusions: Our study help to better understand the underlying molecular mechanisms of G2 improve the salt tolerance of G. uralensis.
Project description:Purpose: The goal of this study are to reveal the internal mechanism of Bacillus pumilus G5 and silicon increased Glycyrrhiza uralensis Fisch. seedlings drought-tolerance by RNA-Seq. Methods: mRNA profiles of Glycyrrhiza uralensis Fisch. Seedling in five treatment: control treatment, drought stress treatment, drought stress with G5 treatment, drought stress with Si treatment and drought stress with G5 combined Si treatment. Results: The full-length transcriptome sequencing of 15 samples was completed, and the clean data of each sample was 6.28GB. All the consistent transcript sequences were aligned to the reference genome by minimap2 software and then de-redundant analysis was performed. Finally, 37267 genes were obtained. A total of 6934 DEGs were identified in four comparisons (D vs CK, DB vs D, DSi vs D, and DBSi vs D), among which are 967, 1559, 1278 and 3130 DEGs in four comparisons, respectively. Conclusions: Our study help to better understand the underlying molecular mechanisms of Bacillus pumilus G5 and silicon improve the drought-tolerance of G. uralensis.
