MiRNAs expression in two soybean root with contrasting cadmium tolerance

ABSTRACT: MicroRNAs (miRNAs) play crucial roles in regulating the expression of various stress responses genes in plant. To investigate soybean (Glycine max) miRNAs involved in the response to cadmium (Cd), microarrays containing 953 unique miRNA probes were employed to identify differences in the expression patterns of the miRNA between different genotypes, Huaxia3 (HX3, Cd-tolerant) and Zhonghuang24 (ZH24, Cd-sensitive). A total of 26 Cd-responsive miRNAs were identified, of which nine were detected in both cultivars, while five were expressed only in HX3 and 12 were only in ZH24.

In the study presented here, four root samples from two contrast soybean cultivars, HX3 (Cd-tolerant) and ZH24 (Cd-sensitive), with or without (Cd) cadmium, harvested at 6, 12, 24, 48, 96 and 144 h after the initiation of Cd treatment, was used to acquire expression profiles of a total of 953 unique genes, leading to the successful construction of supervised.

Endogenous miRNA targets identified by sequencing of the Soybean degradome

Project description:To identify more targets in soybean, particularly specific targets of Cd-stress-responsive miRNAs, high-throughput degradome sequencing was used. In total, we obtained 8913111 raw reads from the library which was constructed from a mixture of four samples (HX3-CK, HX3-Cd-treatment, ZH24-CK and ZH24-Cd-treatment). After removing the reads without the CAGAG adaptor, 5430126 unique raw-reads were obtained. The unique sequences were aligned to the G. max genome database, and 6516276 reads were mapped to the genome. The mapped reads from the libraries represented 51481 annotated G. max genes.

Identifying salt stress-responsive miRNAs and their targets in soybean (microRNA)

Project description:MicroRNAs (miRNAs) play an important role as regulators of gene expression. In plants they affect a wide variety of biological process like growth, development and response to biotic and abiotic stress. Glycine max is one of the most important crop worldwide due to its rich protein and oil content. Drought and salt stress are the main abiotic stresses that affect soybean. Salt stress impacts the fisiology of the plants due to the damage in the photosynthetic rate, growth and development. This work aim to identify salt-stress responsive miRNAs and their respective targets in Glycine max using high-throughput RNA sequencing technology.

An integrated analysis of small RNAs, degradome and transcriptome in rice seedling exposure to cadmium stress [degradome]

Project description:Cadmium (Cd) influence in rice is a growing global environmental concern. Although many miRNAs and target genes have been identified in rice exposure to Cd stress, no comprehensive study has been done comprising integrative analysis of small RNAs, degradome and trascriptome sequencing to identify Cd-regulated miRNAs and their targets under Cd stress. In this study, 40 miRNAs including 38 known miRNAs representing 22 miRNA families and 2 novel miRNAs were substantially altered in response to Cd exposure. 18 differentially altered target genes were inversely correlated with 18 Cd responsive miRNAs. Majority of these targeted genes are transcript factors such as Auxin response factor 13 (ARF13), Scarecrow-like protein 6 (SCL6), Squamosa promoter-binding-like proteins (SPLs), Nuclear transcription factor Y subunit A-6 (NFYA6), Gibberellin-dependent avian myeloblastosis virus oncogene (GAMYB) and No apical meristem protein domain containing proteins (NACs), most of which were involved in signal transduction such as abscisic acid (ABA), Auxin, Gibberellin acid (GA) and MAPK (Mitogen-activated protein kinase). Functional analysis revealed that genes involved in photosynthesis pathway (osa00196, osa00195 and osa00710) and protein degradation pathway (osa04612) were identified to be participated in response to Cd in rice, including osa-miR156I-5p_R-1/SPLs, osa-miR171a_1ss12CT/DEGP10 and osa-miR169r-5p_R/NFYA6 circuits, respectively. We conclude that a combination of transcriptome, sRNAs and the degradome would confer a useful approach to investigate miRNA-mediated molecular mechanisms underlying plant response to Cd stress.

Environmental cadmium-induced circRNA-miRNA-mRNA network regulatory mechanism in human normal liver cell model [mRNA]

Project description:Cadmium is a naturally existing heavy metal and a typical environmental pollutant which is a significant threat to human health and can lead to acute and chronic damage to various organs. At present, hundreds of lncRNAs and miRNAs have been confirmed to be related to the toxicity of Cd. However, the role of circRNA in the toxicity of Cd and the involved regulatory mechanism has not been clarified. In this work, human normal liver cell (L-02) was selected as model to identify the changes in the expression level of circRNA after exposure to Cd. Total RNA of each sample was extracted by Trizol method, the original data of circRNA, miRNA and mRNA expression levels of each sample were obtained by microarray hybridization and scanning were standardized and differentially expressed. Differential circRNAs, miRNAs, and mRNAs associated with the toxic effects of Cd were identified. Construct a ceRNA network by screening the predicted circRNA, miRNA and mRNA and predict the main biological functions and metabolic pathways of the network. A total of 266 different circRNAs, 223 different miRNAs and 519 different mRNAs were identified by differential expression analysis. After screening, seven circRNAs, 10 miRNAs and 97 mRNAs were constructed into ceRNA network. After GO enrichment and KEGG pathway analysis of 97 mRNAs in circRNA-miRNA-mRNA network, indicated that circRNA in the ceRNA network may regulate cell proliferation, apoptosis, oxidative stress and inflammatory response under the toxic effect of Cd to damage L-02, and it has obvious dose-response effect and time effect.
