“…The gamma-ray-responsive miRNAs seem to be significantly affected by the genome-wide DNA methylation level. Expression of the miR164 family has also been reported to be induced by UV-B radiation and carbon ion (Jia et al, 2009;Zhang et al, 2011a) and expression of miR169 and miR827 was substantially increased after H 2 O 2 treatment (Li et al, 2011). In the present study, these miRNAs may be associated with general light-or stress-related signals induced by gamma irradiation.…”

“…For comparison, we performed a literature search to investigate what miRNAs respond to H 2 O 2 or UV-B radiation as well as ionizing radiation (Table 1); however, only a few articles could be identified. Expression of the miR156 and miR164 families was found to respond to UV-B radiation and carbon ions (Jia et al, 2009;Zhang et al, 2011a;Casati, 2013;Wang et al, 2013), while expression of the miR169 family was affected by UV-B radiation and H 2 O 2 (Zhou et al, 2007;Jia et al, 2009;Li et al, 2011). Previously, we demonstrated that genome-wide transcriptional changes in Arabidopsis seedlings subjected to gamma irradiation were most clear at 6 h and then decreased until 48 h (Kim et al, 2013b).…”

“…Distinctive cis-elements in the 5'-upstream sequences or putative promoter regions of UV-B-responsive miRNA genes have been identified in A. thaliana, Populus tremula, and Triticum aestivum (Zhou et al, 2007;Jia et al, 2009;Wang et al, 2013). Many of the UV-Bresponsive cis-elements including G-box, I-box core, ARE, and MBS were frequently found in the putative promoter regions of gamma-ray-responsive miRNA genes (Table 3).…”

“…In relation to UV-B radiation, various miRNA gene families, including miR156, miR159, miR160, miR164, miR167, miR169, miR395, and miR171, were identified as UV-B radiation-responsive genes in Arabidopsis thaliana, Populus tremula, and/ or Triticum aestivum (Zhou et al, 2007;Jia et al, 2009;Wang et al, 2013). UV-B-responsive miRNA genes were found to possess various light-responsive and stress-related cis-elements in their upstream regions.…”

ABSTRACT. MicroRNAs (miRNAs) regulate gene expression in response to biotic and abiotic stress in plants. We investigated gammaray-responsive miRNAs in Arabidopsis wild-type and cmt3-11t mutant plants using miRNA microarray analysis. miRNA expression was differentiated between the wild-type and cmt3-11t mutants. miR164a, miR169d, miR169h, miR172b*, and miR403 were identified as repressible in the wild-type and/or cmt3-11t mutant in response to gamma irradiation, while miR827, miR840, and miR850 were strongly inducible. These eight miRNA genes contain UV-B-responsive ciselements, including G-box, I-box core, ARE, and/or MBS in the putative promoter regions. Moreover, Box 4, MBS, TCA-element, and Unnamed_4, as well as CAAT-and TATA-box, were identified in these eight miRNA genes. However, a positive correlation between the transcriptions of miRNAs and their putative target genes was only observed between miR169d and At1g30560 in the wild-type, and between miR827 and At1g70700 in the cmt3-11t mutant. Quantitative RT-PCR analysis confirmed that the transcription of miR164a, miR169d, miR169h, miR172b*, miR403, and miR827 differed after gamma irradiation depending on the genotype (wild-type, cmt3-11t, drm2, drd1-6, and ddm1-2) and developmental stage (14 or 28 days after sowing). In contrast, high transcriptional induction of miR840 and miR850 was observed in these six genotypes regardless of the developmental stage. Although the actual target genes and functions of miR840 and miR850 remain to be determined, our results indicate that these two miRNAs may be strongly induced and reproducible genetic markers in Arabidopsis plants exposed to gamma rays.

“…Twenty-one miRNAs, belonging to the following 11 miRNA families, were identified in Arabidopsis and predicted to be upregulated under UV-B stress: miR156/157, miR159/319, miR160, miR165/166, miR167, miR169, miR170/171, miR172, miR393, miR398, and miR401 (Zhou et al, 2007). In Populus tremula, miR156, miR160, miR165/166, miR167, miR398, and miR168 were also reported to be upregulated by UV-B radiation (Jia et al, 2009).…”

ABSTRACT. MicroRNAs (miRNAs) play critical roles in posttranscriptional gene regulation and act as important endogenous regulators to various stressors. Ultraviolet-B (UV-B) radiation is a major factor influencing crop growth and development. In this study, we isolated a novel wheat miRNA, named Tae-miR6000, and confirmed its expression diversity after UV-B treatments. Additionally, using the Northern blotting technique, we found that six miRNAs were highly responsive to UV-B stress in wheat. Of these six miRNAs, miR159, miR167a, and miR171 were significantly upregulated, and the remaining three miRNAs were downregulated, at different time points after UV-B treatment. This result indicates that miRNAs may be involved in the regulation of targets after induction by UV-B stress. Furthermore, promoter analysis of the UV-B-responsive miRNA genes revealed some light-relevant cis-elements, such as the I-box and G-box. Taken together, the results of this study suggest that wheat miRNAs play important roles in the response to UV-B stress.
