Our results provided direct evidence that pf40 gene play a role in the tissue development, with knockout this gene the lateral buds were not visible. the plant hormones auxin and cytokinin appear to play a major role in controlling this process, therefore, the concertrition of auxin and cytokinin was measured, however, the concentration of the two hormone was variation a little in transgenic plants, but the ratio of the two was more than 5 fold in the pf40 gained function plant than that in wild type. furthermore the pf40 gene effected differentiation of the vascular bundles in different transgenic plants, results showed the pf40 could change both xylary fibers and vessel

    進一步的實驗現pf40基因會影響植物側芽期,即pf40基因作用在側芽形成與期。對轉基因穀子的組織切片的分析還表明pf40基因引起不同形式的轉基因穀子的維管組織的的差異,轉化正義載體穀子的木質部變多,維管系統增多,而反義或干擾的轉基因穀子的木質部數量變少,木質部分化異常。從轉基因的結果可見pf40基因可以減弱植物的頂端優勢,這種作用是通改變植物體內激素的含量實現的。
