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.
在20个玉米自交系中对包括开花和成熟时间在内的物候期持续时间进行了表征。在六个成熟时间不同的玉米品系的幼苗中，研究了长光周期条件下关键开花起始基因（CONZ1、GIGZ1a、GIGZ1b、ZmFKF1a和ZmFKF1b）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显著更低。GIGZ1a和GIGZ1b旁系同源基因观察到相似的表达模式，而ZmFKF1a在表达上明显高于其旁系同源基因ZmFKF1b。
