杨树两个MADS-box基因通过介导生长素浓度调控木材形成

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，数据内容是杨树两个MADS-box基因通过介导生长素浓度调控木材形成。 VCM1 和 VCM2 直接调控了生长素转运蛋白PIN5的表达，而PIN5则将胞质内生长素转运到内质网中，降低胞质内生长素的浓度，影响维管形成层区域细胞内生长素信号强度，实现对维管形成层分裂活性和木质部分化的调控。This dataset is derived from a research paper under the project studying molecular regulation and environmental stress response mechanisms of secondary forest growth. The core content of this dataset focuses on the regulatory mechanism that two MADS-box genes in poplar, VCM1 and VCM2, control wood formation by mediating auxin concentration. Specifically, VCM1 and VCM2 directly regulate the expression of the auxin transporter PIN5. PIN5 transports auxin from the cytoplasm into the endoplasmic reticulum, which reduces the cytoplasmic auxin concentration, alters the intensity of auxin signaling within the vascular cambium region, and thus regulates the mitotic activity of vascular cambium and xylem differentiation.
