资源简介：
该数据是林木次生生长的分子调控和环境胁迫机制项目论文，数据内容是TDIF过表达抑制了转基因杨树节间伸长和增加了叶脉发育。杨树中过表达TDIF上调了GA2ox和GA20ox基因的表达，降低了内源性GA的水平，从而严重抑制了节间伸长，在叶脉中TDIF增加了PIN1基因转录水平，说明TDIF调控不同激素调控多种生物学过程。
This dataset is from a research paper focused on the molecular regulation and environmental stress response mechanisms of secondary growth in forest trees. The core data shows that overexpression of TDIF inhibits internode elongation and promotes vein development in transgenic poplar. Specifically, overexpressing TDIF in poplar upregulates the expression of GA2ox and GA20ox genes, reduces the levels of endogenous gibberellin (GA), thereby severely suppressing internode elongation. Additionally, TDIF increases the transcription level of the PIN1 gene in leaf veins, indicating that TDIF regulates multiple biological processes via distinct hormonal regulatory pathways.
