Fig. 4From: Evolutionary assessment of SQUAMOSA PROMOTER BINDING PROTEIN-LIKE genes in citrus relatives with a specific focus on floweringSPL orthologs exhibit species-specific expression variation. a Different organizations. the bars represent 1cm. b Gene expression detection. YL, juvenile leaf; AL, adult leaf; YB, juvenile bud; AB, adult bud; FL, fully open flower; The darker the blue, the higher the expression level. Values represent relative expression levels. Three biological replicates were conducted for each group of experiments, and the expression level of Actin was used as an internal controlBack to article page
