Identification and characterization of cold responsive microRNAs in tea plant (Camellia sinensis) based on high-throughput sequencing and their targets using degradome analysis [microarray]

ABSTRACT: Solexa sequencing technology was used to perform high throughput sequencing of the small RNA library from the cold treatment of tea leaves. Subsequently, aligning these sequencing date with plant known miRNAs, we characterized 112 C. sinensis conserved miRNAs. In addition, 215 potential candidate miRNAs were found; among them, 131 candidates with star sequence were chosen as novel miRNAs. There are both congruously and differently regulated miRNAs, and line-specific miRNAs were identified by microarray-based hybridization in response to cold stress. The miRNA chip included 3228 miRNA probes corresponding to miRNA transcripts listed in Sanger miRBase release 19.0 and 283 novel miRNAs probes founding in tea plant. In the study presented here, two tea plant cultivars, ‘Yingshuang’ (YS, a cold-tolerant tea plant cultivar) and ‘Baiye 1’ (BY, a cold-sensitive tea plant cultivar), were kept at 4°C for 4,12, 24 h, respectively, and 28°C for as control. These samples were used to acquire expression profiles of a total of 3,511 unique genes, leading to the successful construction of supervised

<h4>Background</h4>MicroRNAs (miRNAs) are approximately 19 ~ 21 nucleotide noncoding RNAs produced by Dicer-catalyzed excision from stem-loop precursors. Many plant miRNAs have critical functions in development, nutrient homeostasis, abiotic stress responses, and pathogen responses via interaction with specific target mRNAs. Camellia sinensis is one of the most important commercial beverage crops in the world. However, miRNAs associated with cold stress tolerance in C. sinensis remains unexplore ...[more]

Project description:The sea cucumber Apostichopus japonicus withstands high water temperatures in the summer by suppressing metabolic rate and entering a state of aestivation. We hypothesized that changes in the expression of miRNAs could provide important post-transcriptional regulation of gene expression during hypometabolism via control over mRNA translation. The present study analyzed profiles of miRNA expression in the sea cucumber respiratory tree using Solexa deep sequencing technology. We identified 279 sea cucumber miRNAs, including 15 novel miRNAs specific to sea cucumber. Animals sampled during deep aestivation (DA; after at least 15 days of continuous torpor) were compared with animals from a non-aestivation (NA) state (animals that had passed through aestivation and returned to an active state). We identified 30 differentially expressed miRNAs ([RPM (reads per million) >10, |FC| (|fold change|) M-bM-^IM-%1, FDR (false discovery rate) <0.01]) during aestivation, which were validated by two other miRNA profiling methods: miRNA microarray and real-time PCR. Among the most prominent miRNA species, miR-124, miR-124-3p, miR-79, miR-9 and miR-2010 were significantly over-expressed during deep aestivation compared with non-aestivation animals, suggesting that these miRNAs may play important roles in metabolic rate suppression during aestivation. In the present study, an analysis of the global profile of small RNAs was conducted using Solexa sequencing technology in non-aestivation (NA) and deep aestivation (DA) sea cucumbers. We focus on respiratory tree in the present study because it is the important site responsible for the strong metabolic rate depression seen under deep aestivating conditions and the global expression profile of mRNA from the this organ has also been constructed applying RNA-seq technology in our previous study (Zhao and Chen, unpublished data). A preliminary analysis of the functional relevance of miRNA expression in relation to hypometabolism during aestivation is presented. A miRNA microarray and RT-qPCR were both used to supplement and confirm differentially expressed miRNAs. Our findings provide important new insights into the molecular mechanisms of sea cucumber aestivation.

Project description:The regulatory role of miRNA in gene expression is an emerging hot new topic in the control of hypometabolism. Sea cucumber aestivation is a complicated physiological process that includes obvious hypometabolism as evidenced by a decrease in the rates of oxygen consumption and ammonia nitrogen excretion, as well as a serious degeneration of the intestine into a very tiny filament. To determine whether miRNAs play an important regulatory roles in this process, the present study analyzed profiles of miRNA expression in the intestine of sea cucumber (Apostichopus japonicus), using Solexa deep sequencing technology. We identified 309 sea cucumber miRNAs, including 19 novel miRNAs specific to sea cucumber. Animals sampled during deep aestivation (DA) after at least 15 days of continuous torpor, were compared with animals from a non-aestivation (NA) state (animals that had passed through aestivation and returned to an active state). We identified 42 differentially expressed miRNAs (RPM (reads per million) >10, |FC| (|fold change|) M-bM-^IM-%1, FDR<0.01) during aestivation, which were validated by two other miRNA profiling methods: miRNA microarray and real-time PCR. Among the most prominent miRNA species, miR-200-3p, miR-2004, miR-2010, miR-22, miR-252a, miR-252a-3p and miR-92 were significantly over-expressed during deep aestivation compared with non-aestivation animals. Preliminary analyses of their putative target genes suggest that these miRNAs could play important roles in global transcriptional depression during aestivation. In the present study,we present for the first time, using Solexa sequencing technology, an analysis of the global profile of small RNAs in non-aestivation (NA) and deep aestivation (DA) sea cucumbers. We focus on intestine in the present study because it is the major site responsible for the strong metabolic rate depression seen under deep aestivating conditions and the global expression profile of mRNA from the this organ has also been constructed applying RNA-seq technology in our previous study (Zhao and Chen, unpublished data). A preliminary analysis of the functional relevance of miRNA expression in relation to hypometabolism during aestivation is presented. A miRNA microarray and RT-qPCR were both used to supplement and confirm differentially expressed miRNAs. Our findings provide important new insights into the molecular mechanisms of sea cucumber aestivation.
