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.

Project description:Breast cancer risk continues to increase post menopause. Anti-estrogen therapies are available to prevent postmenopausal breast cancer in high-risk women. However, their adverse effects have reduced acceptability and overall success in cancer prevention. Natural products such as hops (Humulus lupulus) and three pharmacopeial licorice (Glycyrrhiza) species have demonstrated estrogenic and chemopreventive properties, but little is known regarding their effects on aromatase expression and activity as well as pro-proliferation pathways in human breast tissue. We show that Gycyrrhiza inflata (GI) has the highest aromatase inhibition potency among these plant extracts. Moreover, phytoestrogens such as liquiritigenin which is common in all licorice species have potent aromatase inhibitory activity, which is further supported by computational docking of their structures in the binding pocket of aromatase. In addition, GI extract and liquiritigenin suppress aromatase expression in the breast tissue of high-risk postmenopausal women. Although liquiritigenin has estrogenic effects in vitro, with preferential activity through estrogen receptor (ER)-β, it reduces estradiol-induced uterine growth in vivo. It downregulates RNA translation, protein biosynthesis, and metabolism in high-risk women’s breast tissue. Finally, it reduces the rate of MCF-7 cell proliferation, with repeated dosing. Collectively, these data suggest that liquiritigenin has breast cancer prevention potential for high-risk postmenopausal women. We then performed gene expression profiling analysis using data obtained from RNA-seq of 4 different cells at two time points.

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:Petunia is an excellent model system, especially for genetic, physiological and molecular studies. Thus far, however, genome-wide expression analysis has been rarely applied because of the lack of sequence information. We applied next-generation sequencing to generate, through de novo read assembly, a large catalogue of transcripts for Petunia axillaris and Petunia inflata. On the basis of the transcriptome of each species, comprehensive microarray chips for gene expression analysis were established and used for the analysis of global- and organ-specific gene expression in both species. In addition, microarray analysis was applied to explore the molecular basis of the seed coat defects in Petunia hybrida mutants, homozygous for a null allele of the AN11 gene, encoding a WDR transcription regulator. Among the transcripts differentially expressed in an11 seeds compared to wild type, many expected targets of AN11 were found but also several interesting new candidates that might play a role in morphogenesis of the seed coat. Our results validate the combination of next-generation sequencing with microarray analyses strategies to identify the transcriptome of two petunia species without previous knowledge of their genome, and to develop comprehensive chips as useful tools for the analysis of gene expression in P. axillaris, P. inflata and P. hybrida. The manuscript describes the creation by next generation sequencing of a large catalogue of the transcriptome of the two Petunia species, that are considered to represent the natural material from which the breeders selected their varieties. This submission represents the transcriptome component of study. The high throughput sequencing data were submitted to SRA (accession numbers: SRA027293, SRP004866.1, SRX036999.2, SRX036998.2).
