To understand the network architecture of miRNA mediated regulations at the genomic and functional levels of rice, we have made an unambiguous annotation of the experimentally verified miRNAs, predicted their targets and the possible biological functions they can affect. Some functions, namely translational and protein modifications and photosynthesis are targeted by higher percentage of miRNA. Using transformation procedures, we constructed a genome scale miRNA-miRNA functional synergistic network (MFSN). The analysis of MFSN modules help to identify miRNAs co-regulating target genes having several interrelated biological processes. Some of these target genes are also co-expressed under particular conditions. For example, the genes co-expressed under drought conditions as well as those targeted by miRNAs present in a MFSN module have interdependent biological processes namely, photosynthesis, cell-wall biogenesis, root development and xylan synthesis. The stress-induced miRNAs and their distributions, and the presence of transcription factors in the target set of MFSN modules were also analyzed.

“…It also led to a decrease in pea fresh weight and in the concentration of leaf pigments and free proline in pea plants. This was accompanied by an increase in malondialdehyde [16] . UV-C radiation decreased soluble carbohydrates, reducing sugar, chlorophyll, and proline concentrations and increasing the concentrations of UV-absorbing pigments, soluble proteins, and glucosinolate in canola leaves ( Brassica napus L.)

BackgroundOnly a small amount of solar ultraviolet C (UV-C) radiation reaches the Earth's surface. This is because of the filtering effects of the stratospheric ozone layer. Artificial UV-C irradiation is used on leaves and fruits to stimulate different biological processes in plants. Grapes are a major fruit crop and are grown in many parts of the world. Research has shown that UV-C irradiation induces the biosynthesis of phenols in grape leaves. However, few studies have analyzed the overall changes in gene expression in grape leaves exposed to UV-C.Methodology/Principal FindingsIn the present study, transcriptional responses were investigated in grape (Vitis vinifera L.) leaves before and after exposure to UV-C irradiation (6 W·m−2 for 10 min) using an Affymetrix Vitis vinifera (Grape) Genome Array (15,700 transcripts). A total of 5274 differentially expressed probe sets were defined, including 3564 (67.58%) probe sets that appeared at both 6 and 12 h after exposure to UV-C irradiation but not before exposure. A total of 468 (8.87%) probe sets and 1242 (23.55%) probe sets were specifically expressed at these times. The probe sets were associated with a large number of important traits and biological pathways, including cell rescue (i.e., antioxidant enzymes), protein fate (i.e., HSPs), primary and secondary metabolism, and transcription factors. Interestingly, some of the genes involved in secondary metabolism, such as stilbene synthase, responded intensely to irradiation. Some of the MYB and WRKY family transcription factors, such as VvMYBPA1, VvMYB14, VvMYB4, WRKY57-like, and WRKY 65, were also strongly up-regulated (about 100 to 200 fold).ConclusionsUV-C irridiation has an important role in some biology processes, especially cell rescue, protein fate, secondary metabolism, and regulation of transcription.These results opened up ways of exploring the molecular mechanisms underlying the effects of UV-C irradiation on grape leaves and have great implications for further studies.
