“…Previous studies suggest that the miR396 family likely is involved in the plant stress response (Liu et al 2008;Sunkar and Jagadeeswaran 2008;Qiu et al 2009). We examined the expression pattern of an osa-miR396 family member and found that osa-miR396c has a more definitive expression change in its response to stress compared with other members.…”

Salt and alkali stress are two of the main environmental factors limiting rice production. Thus, understanding the mechanisms of salinity and alkali stress tolerance is necessary to modify rice to increase its resistance to salinity and alkaline stress. MicroRNAs (miRNAs) are approximately 21-nucleotide RNAs that are ubiquitous regulators of gene expression in eukaryotic organisms. In plants, miRNAs constitute one of five classes of small RNAs that function primarily as negative regulators for gene expression at the posttranscriptional level. Several plant miRNAs, such as miR396, play vital roles in plant growth, development and resistance to stresses. In this study, we identified osa-MIR396c, which shows dramatic transcript change under salt and alkali stress conditions in Oryza sativa. We designed an experiment to detect miRNA-target interaction and demonstrated that several transcription factors related to growth, development, and stress tolerance are targeted by osa-MIR396c. Transgenic rice and Arabidopsis thaliana plants constitutively over-expressing osa-MIR396c showed reduced salt and alkali stress tolerance compared to that of wild-type plants. Overall, this study further established a link between salt and alkali stress and osa-MIR396c in rice.

“…Multiple miR396 loci are present in Arabidopsis (ath-MIR396a and ath-MIR396b) and rice (osa-MIR396a*f) (Jones-Rhoades and Bartel 2004). Recent studies indicate that miR396 may be one of the miRNAs involved in plant stress tolerance (Liu et al 2008;Sunkar and Jagadeeswaran 2008;Qiu et al 2009). …”

“…This technology facilitates the investigation of small RNA populations in economically important species which lack complete genome information, such as tomatoes [12] . Using this approach, many new miRNAs have been identified in plants, such as tomato [12] and Chinese yew [13] . There have been three sequencing approaches, including 454, Solexa and Illumia, used to indentify miRNAs.…”

“…There have been three sequencing approaches, including 454, Solexa and Illumia, used to indentify miRNAs. Using these approaches, miRNAs have been identified in plants, such as Illumina used for Chinese yew [13] , and 454 used for tomatoes [12] . Compared with the first two methods mentioned above, the third approach is a high throughput, simple method, i.e.a computational survey through the whole genome sequence, based on the major characteristics of miRNAs and their precursors [10,14] .…”

microRNAs (miRNAs) are a class of endogenous, non-coding, short (approximately 21 nt) RNAs directly involved in regulating gene expression at the post-transcriptional level. Previous reports have noted that plant miRNAs in the plant kingdom are highly conserved, which provides the foundation for identification of conserved miRNAs in other plant species through homology alignment. Conserved miRNAs in wheat are identified using EST (Expressed Sequence Tags) and GSS analysis. All previously known miRNAs in other plant species were blasted against wheat EST and GSS sequences to select novel miRNAs in wheat by a series of filtering criteria. From a total of 37 conserved miRNAs belonging to 18 miRNA families 10 conserved miRNAs comprising 4 families were reported in wheat. MiR395 is found to be a special family, because three members belonging to the same miR395 family are clustered together, similar to animal miRNAs. MiRNA targets are transcription factors involved in wheat growth and development, metabolism,and stress responses.

“…Moreover, the flavor of prepared tea could also be affected by insect infestation, stresses, and mechanical injury to tea plants (Bailey et al, 2005;Bhattacharyya et al, 2007;Cho et al, 2007). Methyl jasmonate (MeJA), a well-characterized fatty acid-derived cyclopentanone signal, can induce a series of changes in secondary metabolites in a wide range of plants (Alvarez et al, 2009;Kuźma et al, 2009;Qiu et al, 2009;Chen et al, 2011). MeJA plays an important role in promoting the quality of agricultural products, especially in improving the aroma qualities of certain fruits and vegetables.…”

Methyl jasmonate (MeJA) was widely applied in promoting food quality. Aroma is one of the key indicators in judging the quality of tea. This study examined the effect of exogenous MeJA treatment on tea aroma. The aroma components in black tea prepared from MeJA-treated fresh tea leaves were extracted using headspace solid-phase microextraction (HS-SPME) and were analyzed using gas chromatography-mass spectrometry (GC-MS) and GC-olfactometry (GC-O). Forty-five volatile compounds were identified. The results revealed that the MeJA-treated black tea had higher levels of terpene alcohols and hexenyl esters than the untreated tea. Moreover, several newly components, including copaene, cubenol, and indole, were induced by the MeJA treatment. The activities of polyphenol oxidase and β-glucosidase in fresh tea leaves changed after the MeJA treatment. Quantitative real-time polymerase chain reaction (qRT-PCR) analysis indicated that the gene expression levels of polyphenol oxidase and β-primeverosidase were upregulated by two and three folds, respectively, by the MeJA treatment (P<0.01); however, the gene expression of β-glucosidase was downregulated to a half level. In general, the aroma quality of the MeJAtreated black tea was clearly improved.
