Project description:We aimed to identify miRNA regulated by alternate bearing in O. europaea. For this purpose, six olive (Olea europaea L. )(Ayvalık variety) small RNA libraries were constructed from fruits (ripe and unripe) and leaves ("on-year" and "off-year" mature -leaven in November and juvenile - leaven in July plants) and sequenced by high-throughput Illumina sequencing. Bioinformatics analyses of 93,526,915 reads identified 135 conserved miRNA, belonging to 22 miRNA families in olive tree. In addition, 38 novel miRNA were discovered in the datasets. Expression of olive tree miRNA varied greatly among the six libraries, indicating contribution of diverse miRNA in balancing between reproductive and vegetative phases. The differential expression of miRNA was evaluated on the basis of the developmental phase of the samples.

Project description:Supplementing diets with olive by-products offers promising benefits for alleviating animal feeding stress without compromising growth. The aim of this study was to explore the transcriptome of backfat in Iberian pigs fed with two diets based in olive by-products. The pigs were divided in three diet groups: a Control (C) group, a dry olive pulp (DOP) group, which was fed a compound feed elaborated with olive pulp, and a wet crude olive cake (WCOC) group, which was fed a compound feed and olive cake silage supplied ad libitum. Subcutaneous fat biopsies were taken, and transcriptome analysis performed. Compared to a C group, we identified 411 and 924 genes as differentially expressed (DEG; q<0.05, Fold Change>1.5) between the DOP and WCOC diets, respectively. In DOP diet, functions related to polysaccharides metabolism were significantly activated, while WCOC exhibited activated biological processes associated with apoptosis and cellular death. Both diets showed inhibition of functions involved in inflammatory and immune responses, as well as reactive oxygen species production, although enriched by different DEGs. Furthermore, in the WCOC diet, functions related to cholesterol and lipid metabolism were suppressed. In both comparisons, the ADIPOQ gene was overexpressed, playing a key role in the majority of affected functions. In conclusion, our findings suggest that olive by-products may significantly influence the health status of animals, offering potential benefits in enhancing their overall well-being.

Project description:A comparative transcriptomics approach was used as a tool to unravel gene regulatory networks underlying salinity response in olive trees by simulating as much as possible olive growing conditions in the field. Specifically, we investigated the genotype-dependent differences in the transcriptome response of two olive cultivars, a salt tolerant and a salt sensitive. A 135 day long comparative salinity experiment was conducted using one year old trees exposed to NaCl stress for 90 days followed by 45 days of post-stress period. Total RNA was extracted from the root samples after 15, 45 and 90 days of NaCl-treated and un-treated olive trees as well as after 15 and 45 days of post-treatment period and used for microarray hybridizations using a loop design. Hierarchical clustering of differentially expressed transcripts revealed two major, distinct clusters for each cultivar. Despite the limited number of probe set, transcriptional regulatory networks were constructed for the salt-tolerant and salt-sensitive cultivar. The comparison of the salt responsive transcriptional regulatory networks in olive with those reported for Arabidopsis suggests that a tree species might respond in a similar to Arabidopsis way at the transcriptome level under salinity stress.

Project description:Small RNAs of 20 to 25 nucleotides in length maintain genome integrity and control gene expression in a multitude of developmental and physiological processes. Despite RNA silencing has been primarily studied in model plants, the advent of high-throughput sequencing technologies has enabled profiling of the small RNA component of more than 40 plant species. Here, use deep sequencing and molecular methods to report the first inventory of small RNAs in olive (Olea europaea). Small RNAs of 24 nts dominate the small RNA transcriptome and atypically accumulate to levels never seen in other plant species, suggesting an active role of heterochromatin silencing in the maintenance and integrity of its large genome. By contrast, small RNAs of 20 to 22 nts were poorly represented in the population at levels lower than those found in most plant species tested. A total of 14 known miRNA families were identified in two libraries prepared from growing and dormant lateral buds. We found that some known miRNAs showed tissue- and/or developmental-specific expression. Also, seven novel, olive-specific miRNA candidates were found in our sequenced set of which 1 were supported by their star strands. Potential precursors for these miRNA candidates with intramolecular folding capacities were found in the olive EST database. Target mRNAs of conserved miRNAs and new olive-specific miRNA were computationally predicted among the olive EST collection and experimentally validated through endonucleolytic cleavage assays.
