摘要

测定了玉米开花起始关键基因（ID1、DLF1、ZCN6、ZCN7和ZCN8）在开花起始期繁殖节和邻近节叶腋的表达谱。在整个测量期间，ID1、DLF1、ZCN7和ZCN8基因表达的节点间动态具有相似性。结果表明，在花序分生组织视觉检测前10天左右，开花激活基因ID1、DLF1、ZCN7、ZCN8在繁殖节点的表达量较邻近节点显著升高，而开花抑制基因ZCN6在所有节点的表达量均降至微量值。

Flowering Initiation Genes Determine the Node for Inflorence-Ear in Zea Mays L.

The expression profile of key genes regulating flowering initiation (ID1, DLF1, ZCN6, ZCN7, and ZCN8) of Zea mays L. was determined in the leaf axils of the reproductive and adjacent nodes during the flowering initiation. The similarity of the inter-node dynamics of the ID1, DLF1, ZCN7, and ZCN8 gene expression was shown throughout the entire measurement period. It was determined that ~10 days before visual detection of the inflorescence meristem, the expression of the flowering activator genes ID1, DLF1, ZCN7, and ZCN8 significantly increased in the reproductive node compared to the adjacent nodes, while the flowering inhibitor gene ZCN6 expression decreased to trace values at all nodes.
