为全面了解赤霉素对番茄子房室形成和扁化转录的调控作用，以子房室数目和扁化转录水平差异较大的两个番茄品种：多室品种'MLK 1'和少室品种'FL 1'为材料，研究赤霉素对番茄子房室形成和扁化转录的影响。通过喷施不同浓度的赤霉素（GA_3）和多效唑（PAC），发现GA_3能增加子房室数量，尤其是对MLK_1的影响最大。同时选择了GA_3和PAC的适宜处理浓度（GA3，80mg·L-1，PAC，80 mg·L-1）结果表明，GA 3抑制了Fashioned转录水平，而PAC则提高了Fashioned转录水平，这表明GA 3通过调控子房室的形成来调控子房室的形成扁平化的转录水平。
To fully understand the regulation effects of gibberellin on tomato (Solanum Lycoperscium) ovary locule formation and the fasciated transcription, two varieties: multi-locule ‘MLK1’ and few- locule ‘FL1’ which were highly different in locule number and fasciated transcriptional levels, were used in this study. By spraying GA3 and PAC (paclobutrazol; an inhibitor of gibberellin biosynthesis) with different concentrations, we found that GA3 increased the locule number, especially, in ‘MLK1’. At the same time, we chose the suitable treatment concentrations of GA3 and PAC (GA3, 80 mg·L -1 , PAC, 80 mg·L -1 ) which were applied on the ‘MLK1’ and ‘FL1’ to analyze the fasciated transcriptional levels and we found that GA3 repressed the fasciated transcriptional level while PAC increased it. The results implied that the GA3 regulated the ovary locule formation through controlling the fasciated transcription levels.
