(Submitter supplied) The male sterility of thermosensitive genic male sterile (TGMS) lines of wheat (Triticum aestivum) is strictly controlled by temperature. The early phase of anther development is especially susceptible to cold stress. MicroRNAs (miRNA) play an important role in plant development and in responses to environmental stress. In this study, deep sequencing of small RNA (smRNA) libraries obtained from spike tissues of the TGMS line under cold and control conditions identified a total of 81 unique miRNA sequences from 30 families, and trans-acting small interfering RNAs (tasiRNAs) derived from two TAS3 genes. more...

(Submitter supplied) Five degradome libraries were constructed from three different seed developmental stages. Separate degradome libraries were constructed for seed coat and cotyledons to identify the tissue specific miRNAs and their potential targets. Sequencing and analysis of degradome libraries gives identification of 183 different targets for 80 known soybean miRNAs. We found 30 cotyledon specific, 18 seed coat specific and 32 miRNAs found in both tissues irrespective of the developmental stages. more...

(Submitter supplied) In our study, small RNA library and degradome library were constructed from developing soybean seeds for deep sequencing. We identified 26 new miRNAs in soybean by bioinformatic analysis, and further confirmed their expression by stem-loop RT-PCR. The miRNA star sequences of 38 known miRNAs and 8 new miRNAs were also discovered, providing additional evidence for the existence of miRNAs. Through degradome sequencing, 145 and 25 genes were identified as targets of annotated miRNAs and new miRNAs, respectively. more...

(Submitter supplied) To fully characterize smRNAs associated with AGO1 and AGO4, we developed a two-step protocol to purify AGO/smRNA complexes from flowers, leaves, roots and seedlings with enhanced purity, and sequenced the smRNAs by Illumina’s technology. We identified some additional miRNAs, collateral miRNAs encoded in known miRNA precursors, phased smRNA clusters and nat-siRNAs. Organ specific sequencing provided digital expression profiles of all obtained smRNAs, especially miRNAs.

(Submitter supplied) In a previous study, seed coat and cotyledon tissues of Williams, Richland and T157 soybean lines were investigated to show tissue specificity of CHS siRNA expression (Tuteja et al., 2009). Here, we investigated more tissues such as leaf, root and germinating cotyledon to ascertain the tissue specificity of CHS siRNAs in Williams. Data from multiple small RNA libraries were sequenced deeply by the Illumina high-throughput sequencing technology. more...

(Submitter supplied) The I locus is a 27-kb inverted repeat cluster of chalcone synthase genes CHS1-3-4 that mediates siRNA down-regulation of CHS7 and CHS8 target mRNAs during seed development leading to yellow seed coats lacking anthocyanin pigments. Here, we report small RNA sequencing of ten stages of seed development from a few days post fertilization through maturity, revealing the amplification from primary to secondary short interfering RNAs (siRNAs) occurring during development. more...

(Submitter supplied) Endogenous 24nt short interfering RNAs (siRNAs) derived mostly from intergenic and repetitive genomic regions constitute a major class of endogenous small RNAs in Arabidopsis thaliana. Accumulation of A. thaliana 24nt siRNAs requires the Dicer family member DCL3, and clear homologs of DCL3 exist in both flowering and non-flowering plants. However, the absence of a conspicuous 24nt peak in the total RNA populations of several non-flowering plants has raised the question of whether this class of siRNAs might, in contrast to the ancient 21nt microRNAs (miRNAs) and 21-22nt trans-acting siRNAs (tasiRNAs), be an angiosperm-specific innovation. more...

(Submitter supplied) MicroRNAs (miRNAs) are endogenous non-coding ~21 nucleotide (nt) RNAs that regulate gene expression at transcriptional and post-transcriptional levels in plants and animals. They play an important role in development, abiotic stress responses or pathogen responses. miRNAs with their related target genes have been widely studied in model plants，and increasing studies have been performed on some crops，however, the number of identified miRNAs in cotton was limited, and global identification of related targets through degradome sequencing has not been developed previously. more...

(Submitter supplied) The role of on-CG methylation in seed development and dormancy remains unknown. There are four genes in charge of non-CG methylation in Arabidopsis: drm1, drm2, cmt2 and cmt3. The majority of non-CG methylation in vegetative tissues, leaf, is gone in homozygous ddcc mutant line (Hume et al., 2014). To uncover the possible role of non-CG DNA methylation in seed development and dormancy, we characterized the transcriptome of ddcc mutant in Arabidopsis post-mature green seeds using Illumina sequencing. more...

(Submitter supplied) There are four major seed developmental phases in Arabidopsis seed development: morphogenesis, maturation, dormancy and germination. What methylation changes occurring in the different phases, if any, remains unknown. To uncover the possible role of DNA methylation in different parts of the seed, we characterized the methylome of four major seed developmental phases of Arabidopsis using Illumina sequencing: global stage (glob) and linear cotyledon stage (lcot) for morphogenesis phase; mature green stage (mg) and post mature green stage (pmg) for maturation phase; dry seed (dry) for dormancy phase; leaves (leaf) from 4 week plant for vegetative tissues.

(Submitter supplied) Seeds are comprised of three major parts of distinct parental origin: the seed coat, embryo, and endosperm. The maternally-derived seed coat is important for nurturing and protecting the seeds during development. By contrast, the embryo and the endosperm are derived from a double fertilization event, where one sperm fertilizes the egg to form the diploid zygote and the other sperm fertilizes the central cell to form the triploid endosperm. more...
