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. Sequences of six olive miRNAs (Olea europaea L. )(Ayvalık variety) plants (ripe and unripe fruits, leaves of mature and juvenile plants of both "on-year" and "off-year") were generated by Illumina sequencing

Project description:This is an RNA-seq study of the transcriptomic activity of different tissues from adult olive tree cv. Picual on field conditions. This analysis unveiled 53,456 genes with expression in at least one tissue; 32,030 of them were expressed in all organs and 19,575 were found to be potential housekeeping genes. In addition, the specific expression pattern in each part of the plant was studied. The flower was clearly the organ with the highest number of exclusive expressed genes, 3,529, and many of them were involved in reproduction. On the contrary, the stem only showed 229 exclusive expressed genes. The gene ontology (GO) terms analysis of these genes in each organ highlighted some tissue-specific pathways. In general, many of these organ-specific genes are involved in regulatory activities and have nuclear protein localization, with the exception of the leave, where there are also many genes whose coded proteins have plastid localization; to a lesser extent, this was also observed in stems. On the other hand, the pathogen defense and immunity pathways are highly represented in the roots. These data show a complex pattern of gene expression in different organs.

Project description:We carried out genome wide transcriptome analyses in different organs and developmental stages of the olive tree using the NimbleGen Array oligonucleotide probe sets. Cluster analyses of the genes showed that samples collected from different organs could be sorted into separate groups. The nutritional control had a particularly remarkable impact on the alternate bearing for O. europaea, as shown by the differential expressions of transcripts under different developmental phases and organs

Project description:The olive tree (Olea europaea L.) was one of the first plant species in history to be domesticated. Throughout olive domestication, gene expression has undergone drastic changes that may affect tissue/organ-specific genes. This is an RNA-seq study of the transcriptomic activity of different tissues/organs from adult olive tree cv. "Picual" under field conditions. This analysis unveiled 53,456 genes with expression in at least one tissue, 32,030 of which were expressed in all organs and 19,575 were found to be potential housekeeping genes. In addition, the specific expression pattern in each plant part was studied. The flower was clearly the organ with the most exclusively expressed genes, 3529, many of which were involved in reproduction. Many of these organ-specific genes are generally involved in regulatory activities and have a nuclear protein localization, except for leaves, where there are also many genes with a plastid localization. This was also observed in stems to a lesser extent. Moreover, pathogen defense and immunity pathways were highly represented in roots. These data show a complex pattern of gene expression in different organs, and provide relevant data about housekeeping and organ-specific genes in cultivated olive.

Project description:Cultivated olive tree (Olea europaea L. subsp. europaea var. europaea) is one of most relevant worldwide-extended crops. Since this plant has a huge effect on the economy of several regions, especially in those located in the Mediterranean basin, all efforts focused on its protection have a great relevance in agriculture sustainability. As all extended crops, olive tree cultivars are under the threat of a wide range of pathogens. Among them, Verticillium dahliae has been in the spotlight in the last decades because the disease caused by this soil-borne fungus (Verticillium wilt) is easily spread and can eventually kill the tree. In this line, many different factors have been studied in order to shed some light on the molecular/genetic mechanisms underlying the Olea europaea-Verticillium dahliae interaction, some of them focused on the gene expression pattern of the host. In this study, the expression pattern of roots from thirty-six O. europaea cultivars with different resistance/susceptibility degree to Verticillium wilt has been analyzed by RNA-Seq. As a result, processes involved in plant defense, transcription and root development have emerged as potential players in the differential response to Verticillium wilt of these cultivars. Additionally, a quite interesting set of 421 genes with an opposite expression pattern in those cultivars showing extreme resistance/susceptibility to Verticillium wilt has been discovered, establishing a solid group of candidates to take into account in future genetic improvement programs.
