Project description:MicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs involved in the post-transcriptional gene regulation and play a critical role in plant growth, development and stress responses. Watermelon (Citrullus lanatus L.) is one of the important agricultural crops worldwide. Here we carried out computational and experimental analysis of miRNAs and phased small interfering RNAs (phasiRNAs) in watermelon by analyzing 14 small RNA profiles from roots, leaves, androecium, flowers, and fruits, and one published small RNA profile of mixed tissues. To identify the targets of miRNAs and phasiRNAs, we generated a degradome profile for watermelon leaf which is analyzed with the SeqTar algorithm. We identified 97 conserved pre-miRNAs, of which 58 have not been reported previously and 348 conserved mature miRNAs without precursors. We also found 9 novel pre-miRNAs encoding 18 mature miRNAs. One hundred and one 21 nucleotide (nt) PHAS loci, and two hundred and forty one 24 nt PHAS loci were also identified. We identified 120 conserved targets of the conserved miRNAs and TAS3-derived tasiRNAs by analyzing a degradome profile of watermelon leaf. The presented results provide a comprehensive view of small regulatory RNAs and their targets in watermelon.

Project description:BACKGROUND:MicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs involved in the post-transcriptional gene regulation and play a critical role in plant growth, development and stress responses. Watermelon (Citrullus lanatus L.) is one of the important agricultural crops worldwide. However, the watermelon miRNAs and phasiRNAs and their functions are not well explored. RESULTS:Here we carried out computational and experimental analysis of miRNAs and phased small interfering RNAs (phasiRNAs) in watermelon by analyzing 14 small RNA profiles from roots, leaves, androecium, petals, and fruits, and one published small RNA profile of mixed tissues. To identify the targets of miRNAs and phasiRNAs, we generated a degradome profile for watermelon leaf which is analyzed using the SeqTar algorithm. We identified 97 conserved pre-miRNAs, of which 58 have not been reported previously and 348 conserved mature miRNAs without precursors. We also found 9 novel pre-miRNAs encoding 18 mature miRNAs.

We identified 127 conserved targets of the conserved miRNAs and TAS3-derived tasiRNAs by analyzing a degradome profile of watermelon leaf.

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that regulate target mRNAs by inducing degradation or preventing translation of their target mRNAs. Rose, Rosa rugosa Thunb., is an important ornamental and edible plant, yet there are only a few studies on the miRNAs of rose. Here we carried out computational and experimental analysis of miRNAs and phased small interfering RNAs (phasiRNAs) in rose by analyzing 10 small RNA profiles from roots, petals, pollens, stamens, and leaves. To identify the targets of miRNAs and phasiRNAs, we generated a degradome profile for rose leaf which is analyzed using the SeqTar algorithm. This study identified 25 conserved pre-miRNAs, of which 24 have not been reported previously. We also found 22 novel pre-miRNAs. Three hundred and thirty nine 21 nucleotide (nt) PHAS loci, and forty nine 24 nt PHAS loci were also identified. We identified more than 4000 putative targets of the conserved miRNAs using a criteria of less than 4 mismatches between miRNA and targets. Among these targets, at least 171 have shown significant accumulation of degradome reads. Our results demonstrate that the miR482 family triggers the generations of phasiRNAs by targeting nucleotide-binding, leucine-rich repeat (NB-LRR) disease resistance genes in rose. These results significantly enhanced our knowledge of the miRNAs and phasiRNAs, as well as their potential functions in rose.

Project description:In this study, Solexa sequencing technology has been used to discover small RNA populations of self-grafted watermelon and grafted watermelon (bottle gourd and squash were used as rootstocks). A total of 11,458,476, 11,614,094 and 9,339,089 raw reads representing 2,957,751, 2,880,328 and 2,964,990 unique sequences were obtained from the scions of self-grafted watermelon and watermelon grafted on-to bottle gourd and squash at two true-leaf stage, respectively. 39 known miRNAs belonging to 30 miRNA families and 80 novel miRNAs were identified in our small RNA dataset. Compared with self-grafted watermelon, 20 (5 known and 15 novel miRNAs) and 51 (21 known miRNAs and 30 novel miRNAs) miRNAs were expressed significantly different with higher abundance or lower abundance in watermelon grafted on to bottle gourd and squash, respectively. The differentially expressed miRNA target various transcriptional factors and other genes which involved in a wide range of biological processes. This study was firstly conducted to identify and compare miRNAs on genome-wide scale in watermelon grafting system. The miRNAs expressed differentially when watermelon was grafted onto different rootstocks suggesting that miRNAs might play an important role in diverse biological and metabolic processes in watermelon and grafting may possibly by changing miRNAs expression to regulate plant growth and response to stresses. The small RNA transcriptomes obtained in this study provided insights into molecular basis of miRNA regulation of genes expressed in self-grafted and grafted watermelon.

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that play important roles by regulating other genes. Rose, Rosa rugosa Thunb., is an important ornamental and edible plant, yet there are only a few studies on the miRNAs and their functions in rose. Here we carried out computational and experimental analysis of miRNAs, phased small interfering RNAs (phasiRNAs) and mRNAs in rose by analyzing 10 small RNA sequencing profiles from roots, petals, pollens, stamens, and leaves and 4 RNA-seq profiles in leaves and petals of rose. To identify the targets of miRNAs and phasiRNAs, we produced a degradome profile for rose leaf which is analyzed using the SeqTar algorithm. This study identified 25 conserved pre-miRNAs, of which 24 have not been reported previously. We also found 22 novel pre-miRNAs. Three hundred and thirty nine 21 nucleotide (nt) PHAS loci, and forty nine 24 nt PHAS loci were also identified. We identified more than 19,000 putative targets of the conserved miRNAs/tasiRNAs using a criteria of less than 4 mismatches between miRNA and targets. Among these targets, 592 have shown significant accumulation of degradome reads. Our results demonstrate that the miR482 family triggers the generations of phasiRNAs by targeting nucleotide-binding, leucine-rich repeat (NB-LRR) disease resistance genes in rose. Our results also suggest that the deregulated genes in leaves and petals are significantly enriched in GO and KEGG pathways related to metabolic processes and photosynthesis. These results significantly enhanced our knowledge of the miRNAs and phasiRNAs, as well as their potential functions in rose.
