Figures & data
Figure 1. Chromosomal locations and duplications of genes associated with capsaicin synthesis on the Capsicum chinense chromosomes. Note: In the figure, the chromosome number is shown at the top of each bar. The gene clusters are indicated by black lines.
Figure 2. Structural analysis of the capsaicin metabolic genes: (A) NJ phylogenetic tree of capsaicin metabolic proteins; (B) Exon-intron structure of capsaicin metabolic genes. Note: In the figure, yellow indicates the exons; black indicates the introns.
Table 1. Gene names and their corresponding GenBank numbers.
Table 2. Capsaicin metabolic genes in Capsicum chinense.
Figure 3. Promoter cis-regulatory element prediction of genes associated with capsaicin synthesis. Note: Different colors represent different cis elements.
Figure 5. Expression heatmaps of the capsaicin metabolic genes in total fruits [Citation38] and placental tissue in Capsicum chinense L. [Citation12] during the fruit development stage based on the RNA-Seq data. Note: These data were normalized to a row scale. Days after pollination (DAP); Days post-anthesis (DPA); Fruit-Early (20DPA); Fruit-Breaker (30-45DPA); Fruit-Mature (45-60DPA).
