Small RNA-seq analysis in response to methyl jasmonate and abscisic acid treatment in Persicaria minor.

ABSTRACT: Persicaria minor (Kesum) is an important medicinal plant with high level of secondary metabolite contents, especially, terpenoids and flavonoids. Previous studies have revealed that application of exogenous phytohormone could increase secondary metabolite contents of the plant. MicroRNAs (miRNAs) are small RNAs that play important regulatory roles in various biological processes. In order to explore the possible role of miRNA in the regulation of these phytohormones signaling pathway and uncovering their potential correlation, we, for the first time, have generated the smallRNA library of Kesum plant. The library was developed in response to methyl jasmonate (MJ) and abscisic acid (ABA) treatment by using next-generation sequencing technology. Raw reads have been deposited to SRA database with the accession numbers, SRX2655642 and SRX2655643 (MJ-treated), SRXSRX2655644 and SRX2655645 (ABA-treated) and SRX2655646and SRX2655647 (Control).

Project description:BackgroundJasmonic acid (JA) and its derivative, methyl JA (MeJA) are hormonal cues released by plants that signal defense response to curb damages from biotic and abiotic stresses. To study such response, a tropical herbal plant, Persicaria minor, which possesses pungent smell and various bioactivities including antimicrobial and anticancer, was treated with MeJA. Such elicitation has been performed in hairy root cultures and plants such as Arabidopsis and rice, yet how MeJA influenced the proteome of an herbal species like P. minor is unknown.MethodIn this study, P. minor plants were exogenously elicited with MeJA and leaf samples were subjected to SWATH-MS proteomics analysis. A previously published translated transcriptome database was used as a reference proteome database for a comprehensive protein sequence catalogue and to compare their differential expression.ResultsFrom this proteomics informed by transcriptomics approach, we have successfully profiled 751 proteins of which 40 proteins were significantly different between control and MeJA-treated samples. Furthermore, a correlation analysis between both proteome and the transcriptome data sets suggests that significantly upregulated proteins were positively correlated with their cognate transcripts (Pearson's r = 0.677) while a weak correlation was observed for downregulated proteins (r = 0.147).DiscussionMeJA treatment induced the upregulation of proteins involved in various biochemical pathways including stress response mechanism, lipid metabolism, secondary metabolite production, DNA degradation and cell wall degradation. Conversely, proteins involved in energy expensive reactions such as photosynthesis, protein synthesis and structure were significantly downregulated upon MeJA elicitation. Overall protein-transcript correlation was also weak (r = 0.341) suggesting the existence of post-transcriptional regulation during such stress. In conclusion, proteomics analysis using SWATH-MS analysis supplemented by the transcriptome database allows comprehensive protein profiling of this non-model herbal species upon MeJA treatment.
