Secondary Effect

Treatment of topped radishes (Raphanus sativus L., cv. Cherry Belle) with methyl jasmonate was effective in inhibiting postharvest sprouting of new leaves and the growth of roots. Radishes were trimmed to 10-mm tops and dipped in various methyl jasmonate suspensions for 3 min. After storage at 15 °C for 7 days, the growths of new leaves were 26, 22, 7, 3, and 1 mm in 0, 10–5, 10–4, 10–3, or 2 × 10–3 M methyl jasmonate-treated radishes, respectively. The lengths of root growth were also reduced by methyl jasmonate particularly at higher concentrations. These treatments also substantially reduced weight loss possibly as a secondary effect. Fumigation with methyl jasmonate vapor in enclosed containers was also effective in inhibiting the sprouting of leaves and root growth, but to a lesser extent than dipping treatments. Radishes stored at 0 °C did not show any new growth of leaves or roots, and therefore were not affected by the methyl jasmonate treatments.

MicroRNAs (miRNAs) are non-protein coding RNAs of ~20–24 nucleotides in length that play an important role in many biological and metabolic processes, including the regulation of gene expression, plant growth and developmental processes, as well as responses to stress and pathogens. The aim of this study was to identify and characterize novel and conserved microRNAs expressed in methyl jasmonate-treated Scots pine needles. In addition, potential precursor sequences and target genes of the identified miRNAs were determined by alignment to the Pinus unigene set. Potential precursor sequences were identified using the miRAtool, conserved miRNA precursors were also tested for the ability to form the required stem-loop structure, and the minimal folding free energy indexes were calculated. By comparison with miRBase, 4975 annotated sequences were identified and assigned to 173 miRNA groups, belonging to a total of 60 conserved miRNA families. A total of 1029 potential novel miRNAs, grouped into 34 families were found, and 46 predicted precursor sequences were identified. A total of 136 potential target genes targeted by 28 families were identified. The majority of previously reported highly conserved plant miRNAs were identified in this study, as well as some conserved miRNAs previously reported to be monocot specific. No conserved dicot-specific miRNAs were identified. A number of potential gymnosperm or conifer specific miRNAs were found, shared among a range of conifer species.
