In this study , map2 and sap2 , two homologs ofap2 in arabidopsis and hap2 in hyacinthus orientalis l . , were isolated from the flower buds of apple ( mains pumila mill . ) 拟南芥的ap2和ant基因、玉米的gl15 、 ids1基因、矮牵牛的phap2a 、 phap2b基因以及风信子的hap2基因都属于这一基因家族。

The results are as follows : exogenous hormones enhance hft gene expression . sequence alignment suggests hft ( hyacinthus forkhead transcription factor ) is a novel gene . its expressing level was enhanced by the hormones , and lower level were maintained in explants uncultured or cultured without hormones 外源激素提高hft基因的表达水平， hft在外植体接种于含有生长素和细胞分裂素的ms培养基上培养24小时、 5天、 10天和15天的材料中均表达，并且其表达水平逐渐增高。
