摘要

研究了20个玉米自交系玉米（Zea mays L.）在长光周期条件下关键开花起始基因（CONZ1、GIGZ1a、GIGZ1b、ZmFKF1a和ZmFKF1 b）在不同成熟时间的6个玉米系幼苗中的表达。与晚熟品系相比，早熟品系中所有五个基因的转录水平都显著降低。在GIGZ1a和GIGZ1b旁系同源基因中观察到类似的表达模式，而ZmFKF1a的表达显著高于其旁系同源ZmFKF1b。

Expression Levels of Flowering Time Genes (CONZ1, GIGZ1A, GIGZ1B, FKF1A, and FKF1B) in Seedlings under Long-Day Conditions Differentiates Early and Late Zea mays L. Lines.

Phenophase durations, including the timing of flowering and ripeness, were characterized in 20 inbred lines of the maize Zea mays L. Expression of key flowering initiation genes (CONZ1, GIGZ1a, GIGZ1b, ZmFKF1a, and ZmFKF1b) under long-photoperiod conditions was studied in seedlings of six maize lines that differed in ripeness time. Significantly lower transcription levels of all of the five genes were found in early-ripening lines compared with late-ripening lines. Similar expression patterns were observed for the GIGZ1a and GIGZ1b paralogous genes, while ZmFKF1a significantly predominated in expression over its paralog ZmFKF1b.
