The correlation coefficients between SPS activity and sps gene relative expression level in two species fruits were 0.667 and 0.935*, respectively, suggesting that SPS activity and sps gene relative expression level had a significant positive correlation in S. chmielewskii fruit. On the other hand, there was no significant correlation between the relative expression levels of sps and 14- 3-3 (tft1 and tft10), the correlation coefficients were 0.772 and -0.212 in Micro-Tom, -0.246 and 0.443 in S. chmielewskii, respectively (Table 2). In other words, there was no significant correlation between the relative expression of sps and 14-3-3 (tft1 and tft10)
