Project description:MiRNA plays an important role in post-transcriptional gene regulation in plants. Whether TOR is involved in post-transcriptional gene regulation remains unclear in potato and other plants. In this study, we conducted the high-throughput sequencing of genome-wide miRNAs in the potato seedlings for profiling their expression patterns and identifying TOR related miRNAs in potato.

Project description:In order to polish a long-read genome assembly, short-read illumina data was obtained from Heterodera schachtii cysts (Woensdrecht population from IRS, the Netherlands). Cysts where obtained from infected plant material. Nematodes were cleaned using a sucrose gradient centrifugation step. Thereafter DNA was extracted and used for library preparation and sequencing by Illumina NextSeq500.

Project description:Purpose: MicroRNAs (miRNAs) are ubiquitous components of endogenous plant transcriptome. miRNAs are small, single-stranded and ~21 nt long RNAs which regulate gene expression at the post-transcriptional level and are known to play essential roles in various aspects of plant development and growth. Previously, a number of miRNAs have been identified in potato through in silico analysis and deep sequencing approach. However, identification of miRNAs through deep sequencing approach was limited to a few tissue types and developmental stages. This study reports the identification and characterization of potato miRNAs in three different vegetative tissues and four stages of tuber development by high throughput sequencing. Results: Small RNA libraries were constructed from leaf, stem, root and four early developmental stages of tuberization and subjected to deep sequencing, followed by bioinformatics analysis. A total of 89 conserved miRNAs (belonging to 33 families), 147 potato-specific miRNAs (with star sequence) and 112 candidate potato-specific miRNAs (without star sequence) were identified. The digital expression profiling based on TPM (Transcripts Per Million) and qRT-PCR analysis of conserved and potato-specific miRNAs revealed that some of the miRNAs showed tissue specific expression (leaf, stem and root) while a few demonstrated tuberization stage-specific expressions. Targets were predicted for identified conserved and potato-specific miRNAs, and predicted targets of four conserved miRNAs, miR160, miR164, miR172 and miR171, which are ARF16 (Auxin Response Factor 16), NAM (NO APICAL MERISTEM), RAP1 (Relative to APETALA2 1) and HAIRY MERISTEM (HAM) respectively, were experimentally validated using 5′RLM-RACE (RNA ligase mediated rapid amplification of cDNA ends). Gene ontology (GO) analysis for potato-specific miRNAs was also performed to predict their potential biological functions. Conclusions: We report a comprehensive study of potato miRNAs at genome-wide level by high-throughput sequencing and demonstrate that these miRNAs have tissue and/or developmental stage specific expression profile. Also, predicted targets of conserved miRNAs were experimentally confirmed for the first time in potato. Our findings indicate the existence of extensive and complex small RNA population in this crop and suggest their important role in pathways involved in diverse biological processes, including tuber developmental process.

Project description:Nowadays, given the globalization as well as the numerous technological developments and innovations that govern the food market, consumer’s expectations, regarding the food they eat, have increased and the information they receive should be at least reliable. This proof-of- concept study is the first analysis of potato tuber tissue using integrated multi-omics approaches across genome-wide DNA methylation, RNA sequencing and quantitative proteomics to obtain the molecular portrait of famous PGI potatoes of Naxos island. Furthermore, we used metagenomics analysis in order to discriminate potato tubers produced in diverse PGI regions based on the distinct microbiological patterns. Hence, we reveal key molecular factors related to harvest and post-harvest through the dynamics of causal models.

Project description:The anthocyanin glycosides in potato tubers not only provide the plant with bright color and high nutritional value, but also have pharmacological effects such as antioxidant, hypotensive, lipid-lowering and immunity-boosting. However, the regulatory mechanism of anthocyanin in potato tubers is still unclear. In this study, twelve miRNA libraries, three of which are from the Red beauty (R-1, R-2 and R-3), three of which are from the Black kingkong (B-1, B-2 and B-3), three of which are from the Longshu No.7 (Y-1, Y-2 and Y-3) and three of which are from the LK77 (W-1, W-2 and W-3), were constructed and analyzed by high-throughput sequencing. A total of 167.3 M of clean reads were obtained. After the raw reads were subjected to quality control and filtering, 151,010,820 clean tags were obtained from the twelve libraries. The filtered reads were subsequently compared with the updated potato reference genome, and the vast majority of effective reads were successfully mapped. The mapped reads from the twelve libraries covered 77.10-84.48% of the potato genome, therefore, the analysis based on the genome was considered reliable. The lengths of the obtained miRNAs were further analysed to find that 64% of the miRNAs were concentrated at 21bp in length, followed by a higher number of miRNAs at 22bp and 24bp in length.
