“…These proteins were found to be targeted by miRNA families miR-164, -397, -408, -2936, -3434, and -8051, respectively. Such findings were reported by various researchers (Allen et al, 2005;Wang et al, 2012;Ghani et al, 2013). Phytochrome c is an important chromoprotein that is involved in auxin signaling for plant elongation (Favero et al, 2016) targeted by miR-164.…”

IntroductionMicroRNAs (miRNAs) are an extensive class of noncoding small endogenous RNAs of 18 to 26 nt in length that are derived from self-complementary fold-back structures of longer precursor sequences (pre-miRNAs) and are generated by Dicer-like 1 (DCL1) in plants (Bartel, 2004). Mature miRNAs inhibit gene expression at posttranscriptional levels by either targeting mRNAs for degradation or inhibiting protein translation. Both processes are accomplished by the complementary base pairing of miRNAs to their target mRNA sequences (Ambros, 2004). In plants, for a majority of cases, miRNAs interact with their targets through perfect or near-perfect base pairing and lead to target mRNA degradation (Jones-Rhoades et al., 2006). Increasing evidence has revealed that miRNAs play an important role in a wide range of development processes in plants, including cell proliferation, stress response, metabolism, inflammation, and signal transduction (Ambros, 2004;Jones-Rhoades et al., 2006;Zhang et al., 2007a;Ali et al., 2016) and crosskingdom gene regulation (Barozai and Din, 2017). To date, more than 28,645 miRNAs have been identified from 223 species of plants and animals and deposited in the publicly available database miRBase (Release 21) (Griffiths-Jones et al., 2008). The majority of plant miRNAs have been found in species with fully sequenced genomes including 713 from Oryza sativa, 401 from Populus trichocarpa, 384 from Arabidopsis thaliana, 343 from Solanum tuberosum, 321 from Zea mays, and 241 from Sorghum bicolor (Griffiths-Jones et al., 2008). miRNA-related research is continuously growing and miRNAs, along with their functions, are being identified and elucidated using a wide variety of computational tools and experimental methods including direct cloning, deep sequencing, and other approaches. Comparison of miRNAs across multiple plant species has demonstrated that some miRNAs are highly evolutionary conserved from species to species, such as from mosses to higher flowering eudicots in the plant kingdom (Floyd and Bowman, 2004;Zhang et al., 2006aZhang et al., , 2006b. Conservation of miRNA sequences has provided a powerful strategy for identifying miRNAs in other species. Currently, comparative genome-based homolog searches have been used to identify conserved miRNAs in many plant species, including cotton (

“…As a result, the number of nts for the sequences were obtained over the range of 19 -24 with an average of 18 nt. The lengths of mature miRNA sequences and their number of nts in many plants have been measured and counted in the same manner as reported previously (Wang et al, 2012;Barozai, 2012;Ghani et al, 2013).…”

MicroRNAs (miRNAs) are short, endogenous and non-protein coding RNAs that are 18-26 nucleotides (nt) in length. The miRNAs have been shown to play important regulatory roles in almost all plant processes, including responses to various stresses. These regulatory functions of the miRNAs are to negatively control the protein coding sequences at posttranscriptional level. The mature miRNAs (18-26 nt) are generated from long (50-550 nt) precursor miRNAs (pre-miRNAs). Mostly the pre-miRNAs have one mature miRNA sequence in the stem region, but few have been reported with more than one mature miRNAs. Such miRNAs are called pre-miRNA cluster. In current research, various computational tools were used for the identification and characterization of new conserved pre-miRNA clusters and their targets in barley (Hordeum vulgare L.). Consequently, a total 18 new pre-miRNA clusters were identified from 17 miRNAs families in barley from total 501,838 express sequence tags (ESTs).

Mature miRNA sequences lengths and their number of nt in a number of plants have been measured and counted in the same manner previously (Wang et al, 2012;Ghani et al, 2013).…”

MicroRNAs (miRNAs) are short non-protein coding RNAs made up of 18 to 26 nucleotides and produced in a cell endogenously. Most of them are conserved in nature evolutionally and thus providing a logical basis for the prediction of novel miRNAs and their clusters in many plants. In this research, structural and functional approaches have been combined to make prediction of novel miRNA clusters and their targets in wheat. The total numbers of detected novel miRNA clusters were 21 related to 19 miRNA families in wheat.
