SlNAP1 transcripts in different organs of tomato plants and after the treatment of wild-type (WT) fruit with gibberellin (GA) and paclobutrazol (PAC). A Quantitative real-time polymerase chain reaction (qRT-PCR) of SlNAP1 in different tomato organs (root, stem, leaf, and flower) and fruit ripening stages (MG, Br, and Br + 10). B Transcriptional level of SlNAP1 in WT fruit after treatment with GA. C Transcriptional level of SlNAP1 in WT fruit after treatment PAC. The Slactin gene was used as the internal control. Bars indicate mean ± SD of three independent replicates. Asterisks indicate significant differences determined by Student’s t-test (*P < 0.05). qRT-PCR quantitative real-time PCR, MG, mature green, Br breaker, Br + 10 10 days after the breaker, SD standard error
