Transcriptomics

In this study we generated transcriptional atlases for the Greek olive tree cultivars “Chondorlia Chalkidikis” (CHO) and “Koroneiki” (KO), which have distinct characteristics in terms of fruit development and oil production properties. Our analysis involved 14 different tissue types/developmental stages, including young and mature leaves, young and mature shoots, open and closed flowers, young and mature fruits (epicarp plus mesocarp), young and mature endocarps, stalks, as well as roots.

CHO vs KO Differentially Expressed Genes

Supplementary Data S4
Differential gene expression of CHO vs KO tissues/ developmental stages. The volcano plots depict DEGs of stage 2-4 fruit, stage 2-4 endocarp, closed and open flower, young and mature leaf, young and mature shoot, root, as well as stalk tissues of the CHO in contrast to the KO cultivar. Colour-coding was used to signify DEGs with high statistical significance (padj≤ 0.05) and high Log2 Fold Change (1> FC <-1) (red), high statistical significance but low fold change (blue), and no significant DEGs with either high or low fold change (green and blue, respectively). Annotations correspond to genes with biological interest.
