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.

Project description:Genetic changes involved in the juvenile-to-adult transition in the shoot apex of Olea europaea L. occurs years before the first flowering. For the study of the genetic-expression pattern over development, 21 seedlings originating from open pollination of olive cultivar M-bM-^@M-^XArbequinaM-bM-^@M-^Y were grown in a greenhouse in Centro IFAPA M-bM-^@M-^\ChurrianaM-bM-^@M-^] MM-CM-!laga, Spain. At the sixth month the apical shoot was removed and kept for genomic analysis. Any lateral shoot was removed to force the growth along just one axis. Every three months a new (1 cm long) apical-shoot tip was taken, which included the meristem down to two very small young leaves. When the apical-shoot tip is removed the two lateral buds immediately below are activated, one of them is removed, and the other one becomes the new apical-shoot tip. Seedlings reaching 50 nodes or 1 m high were allowed to form a top canopy. From then, the samples were taken from apical shoots of higher branches. We analyzed samples taken from the seedling/tree No 11, in a dense time-course study by microarray analysis. According to the nature of the samples, i.e. the main apical shoots, we had to use single samples during the first 6 to 15 months of growth. This limits the use of the statistics for this period but is compensated for by providing a series of consecutive data that make it possible to ascertain the time course of gene expression over plant development.
