Fig. 5From: Changes in gene expression and metabolic profile of drupes of Olea europaea L. cv Carolea in relation to maturation stage and cultivation areaRelative expression levels of FAD genes in green mature (GM) and turning purple (TP) drupes of ‘Carolea’ populations growing at different meters above sea level (masl), estimated by qRT-PCR after normalization with the CRYPTOCHROME2 (CRY2) housekeeping gene. The results were reported as mean value (± standard deviation) of three replicates. Asterisks indicate significant pairwise differences using Student’s t-test (P ≤ 0.05). The grid at the left of each graph shows the gene expression pattern detected in the drupes through transcriptomic analysisBack to article page
