Gene expression pattern in olive tree organs (Olea europaea L.)

ABSTRACT: 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.

RNA-Seq study on root samples from Olea europaea cultivars

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.

Nutrition metabolism plays an important role in the alternate bearing of the olive tree (Olea europaea L.)

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 Six sample sets were prepared for array analyses: i) unripe fruit (UF); ii) ripe fruit (RF); iii) “on-year” mature leaf (November sample, ON-M); iv) “on-year” juvenile leaf (July sample, ON-J); v) “off-year” mature leaf (November samples, OFF-M); and vi) “off-year” juvenile leaf (July sample, OFF-J).

Olive (Olea europaea) cv.Kalamon: Control vs Salt-treated

Project description:A transcriptomics approach was used as a tool to unravel gene regulatory network underlying salinity response in a salt-tolerant olive cultivar (cv. Kalamon) by simulating as much as possible olive growing conditions in the field. A 135 day long 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. Despite the limited number of probe set, a transcriptional regulatory networks was constructed for the salt-tolerant cultivar.

Proteome regulation during Olea europaea fruit development.

Project description:BackgroundWidespread in the Mediterranean basin, Olea europaea trees are gaining worldwide popularity for the nutritional and cancer-protective properties of the oil, mechanically extracted from ripe fruits. Fruit development is a physiological process with remarkable impact on the modulation of the biosynthesis of compounds affecting the quality of the drupes as well as the final composition of the olive oil. Proteomics offers the possibility to dig deeper into the major changes during fruit development, including the important phase of ripening, and to classify temporal patterns of protein accumulation occurring during these complex physiological processes.Methodology/principal findingsIn this work, we started monitoring the proteome variations associated with olive fruit development by using comparative proteomics coupled to mass spectrometry. Proteins extracted from drupes at three different developmental stages were separated on 2-DE and subjected to image analysis. 247 protein spots were revealed as differentially accumulated. Proteins were identified from a total of 121 spots and discussed in relation to olive drupe metabolic changes occurring during fruit development. In order to evaluate if changes observed at the protein level were consistent with changes of mRNAs, proteomic data produced in the present work were compared with transcriptomic data elaborated during previous studies.Conclusions/significanceThis study identifies a number of proteins responsible for quality traits of cv. Coratina, with particular regard to proteins associated to the metabolism of fatty acids, phenolic and aroma compounds. Proteins involved in fruit photosynthesis have been also identified and their pivotal contribution in oleogenesis has been discussed. To date, this study represents the first characterization of the olive fruit proteome during development, providing new insights into fruit metabolism and oil accumulation process.
