Expression of Tc-MYBPA, TcANR, TcANS and TcLAR genes and accumulation of PAs in Theobroma cacao (Scavina 6; S6) leaves and flowers at various developmental stages. a Transcript levels of Tc-MYBPA, TcANR, TcANS and TcLAR. Expression was determined by semi-quantitative RT-PCR and was calculated relative to the expression of TcActin in each sample. b Levels of soluble PAs expressed as mg PA per g of fresh weight. c Levels of insoluble PAs expressed as mg PA per g of fresh weight. All data are presented as means ± SE, for gene expression data, n ≥ 3, for PA level data, n ≥ 5. FW, Fresh weight
