Project description:MicroRNAs (miRNAs) are endogenous small RNAs that play important roles in various biological and metabolic processes in plants. Caragana intermedia is an important ecological and economic tree species that is prominent in the desert environment of west and northwest China. To date, no investigation into C. intermedia miRNAs has been reported. In this study, high-throughput sequencing of small RNAs was performed to identify both conserved and novel miRNAs, and also their target mRNA genes in C. intermedia. Based on sequence similarity and hairpin structure prediction, 132 putative conserved miRNAs (12 of which were confirmed to form hairpin precursors) belonging to 31 known miRNA families were identified. Ten novel miRNAs (including the miRNA* sequences of three novel miRNAs) were also discovered. The expression of 12 miRNAs was validated in different tissues, and the 12 miRNAs were further assessed by qRT-PCR after salt treatment. Furthermore, 36 potential target genes of 17 known miRNA families and two potential target genes of one novel miRNA were predicted, and some target genes were also assessed by qRT-PCR after salt treatment. Our study provides a basic catalog of miRNAs and their targets, which will promote further understanding of the important roles of miRNAs in C. intermedia and in other species of the leguminous genus, Caragana.

Examination of small RNA expression profiling in three-weeks-old seedings of Caragana intermedia.
Project description:Neurospora intermedia is a heterothallic filamentous ascomycete. In this study we use microarray technology to study the difference in gene expression between vegetative growth and early reproductive development. Neurospora intermedia FGSC#8882 mat-A and FGSC#8782 mat-a. Solid synthetic crossing medium (SCM) was used as a nutrient regime before sampling and processing. Two different conditions were sampled: vegetative mycelial tissue and young reproductive mycelial tissue.
Project description:To explore the role of circRNAs in the regulation of β-thalassemia and provide new evidence and targets for the treatment of β-thalassemia, circRNAs expression profiling was analyzed from patients with β-thalassemia intermedia and major.
