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.

Project description:In this study, two small RNA libraries and two degradome libraries were constructed from roots of Al-treated and Al-free Glycine soja seedlings. For miRNA, a total of 7,287,655 and 7,035,914 clean reads in Al-treated and Al-free small RNAs libraries were generated, and 105 known miRNAs ,51 p3/p5 strands of known miRNA and 80 novel miRNAs were identified. Among them, expression of 34 miRNAs was responsive to Al stress. Through degradome sequencing, 82 and 11 genes were identified as tagerts of known and novel miRNAs obtained from this study, respectively. Gene Ontology (GO) annotations of target transcripts indicated that 52 out of 66 targets cleaved by conserved miRNA families may play role in regulation of transcription. sample 1: Examination of small RNA in Al-free wild soybean roots; sampple 2: Examination of small RNA in Al-treated wild soybena roots; sample 3: identification of miRNA targets in Al-free wild soybean roots; sample 4: identification of miRNA targerts in Al-treated wild soybean roots

Project description:Chilling stress is a major factor limiting the yield and quality of vegetable soybean (Glycine max L.) on a global scale. Systematic identification and function analysis of miRNA under chilling stress could be helpful to clarify the molecular mechanism of chilling resistance. In the present study, two independent small RNA libraries from leaves of vegetable soybean were constructed, and sequenced with the high-throughput Illumina Solexa system. A total of 434 known miRNAs and three novel miRNAs were identified. Moreover, the expression patterns of these miRNAs have been verified by qRT-PCR analysis. Furthermore, we identified their gene targets by high-throughput degradome sequencing and validated using 5'-RACE. A total of 898 transcripts were targeted by 54 miRNA families attributed to five categories. More importantly, we identified 55 miRNAs that differentially expressed between chilling stress and the control. The targets of these miRNAs were enriched in oxidation-reduction, signal transduction, and metabolic process functional categories. The qRT-PCR confirmed that there was a negative relationship among the miRNAs and their targets under chilling stress. Our work provides comprehensive molecular evidence for the possible involvement of miRNAs in the process of chilling-stress responses in vegetable soybean.

Project description: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.

Project description:MicroRNAs (miRNAs) are important post-transcriptional regulators of plant development. In soybean (Glycine max), an important edible oil crop, valuable lipids are synthesized and stored in the cotyledons during embryogenesis .This storage lipids are used as energy source of the emerging seeds, during the germination procces. Until now, there are no microRNAs related to lipid metabolism in soybean or any other plant. This work aims to describe the miRNAome of germinating seeds of B. napus by identifying plant-conserved and novel miRNAs and comparing miRNA abundance in mature versus germinating seeds. A total of 183 familes were detected through a computational analysis of a large number of reads obtained from deep sequencing from two small RNA libraries of (i) pooled germintaing seeds stages and (ii) mature soybean seeds. We have found 39 new mirna precursors which produce 41 new mature forms. The present work also have identified isomiRNAs and mirnas offset (moRNAs). This work presents a comprehensive study of the miRNA transcriptome of soybean germinating seeds and will provide a basis for future research on more targeted studies of individual miRNAs and their functions in lipid consumption in development soybean seeds.

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.
