Figure 3. The Heatmap and cluster analysis of transcripts for the important genes related to the fruit ripening.

Figure 3

Data for gene expression levels were normalized to z-score with the formula log10 (FPKM + 1) by color key and density plot, namely, the from-green-to-red color represents the value of gene expression from low to high during fruit ripening. The gene-coding proteins annotated in the relative pathways: oxidative phosphorylation [NADH dehydrogenase (ubiquinone) flavoprotein 1, H+-transporting ATPase]; glutathione metabolism [glutathione S-transferase (GST), L-ascorbate peroxidase (Vc)]; abscisic acid [ABA, serine/threonine-protein kinase SRK2, protein phosphatase 2C (PP2C)]; protein processing (heat shock 70 kDa protein 5, heat shock 70 kDa protein 1/8, molecular chaperone HtpG); RNA transport (translation initiation factor 1); sugar metabolism [pyruvate dehydrogenase E1 component alpha (PDH), beta-amylase, beta-fructofuranosidase, beta-glucosidase, pyruvate decarboxylase (PDC)]; ethylene [ETH, aminocyclopropanecarboxylate oxidase (ACO), EIN3-binding F-box protein (EBF), S-adenosylmethionine synthetase (SAMS)]; Gibbérelline (GA, DELLA protein); flavonoid biosynthesis [bifunctional dihydroflavonol 4-reductase/flavanone 4-reductase (DFR), chalcone synthase (CHS), chalcone isomerase (CHI), leucoanthocyanidin dioxygenase (LDOX), naringenin 3-dioxygenase (FHT)]; phenylpropanoid biosynthesis [4-coumarate-CoA ligase (4CL)], beta-glucosidase, phenylalanine ammonia-lyase (PAL)]; pentose and glucuronate interconversions [pectinesterase (PE), pectate lyase (PL)]; jasmonate [JA, jasmonate ZIM domain-containing protein (JAZ)]; auxin (IAA, auxin-responsive protein IAA, auxin influx carrier, auxin responsive GH3 gene family); polyamines [PA, S-adenosylmethionine decarboxylase (SAMDC)].
