Abstract:
      The fruits with three growth stages of the two olive varieties Frantoio and EZhi 8 were sequenced by RNA-seq technique. Based on the published literature olive genome, a total of 208 genes with high expression related to oil synthesis were identified. The gene expression activity of two cultivars of olive were very similar in July, while they were significantly different in May and September. This result was consistent with the developmental regulation of fruit formation, in which the cell division was dominant and fruit content accumulated vigorously in the early stage but the oil accumulation tended to be stable in the late stage of development. The research results layed a theoretical foundation for molecular breeding of olive, which could help to improve quality and nutritional value of olive oil by genetic technique.
