大豆品种在开花和成熟的时间上是极其多样的，这是由于不同的光周期敏感性。其分子遗传机制尚不完全清楚，但已鉴定出4个成熟位点E1、E2、E3和E4。本研究从不同生态区筛选出光周期敏感性不同的品种，涵盖了从MG 000到MG VIII和MG X的几乎所有成熟期组（MG），适应于北纬18°到北纬53°。在北京自然光照条件下进行大田种植，或在不同光周期条件下进行盆栽种植。成熟相关性状进行了研究。在分子水平上对4个E成熟位点进行了基因分型。结果表明，这4个E基因对大豆成熟度有不同的影响，它们的等位变异和组合决定了大豆成熟度的多样性和对不同纬度的适应性。野生大豆光周期敏感性和适应性的遗传机制与栽培大豆不同。这四个E基因座的等位基因组合和功能分子标记将显著地帮助分子育种朝着高产方向发展。
Soybean cultivars are extremely diverse in time to flowering and maturation as a result of various photoperiod sensitivities. The underlying molecular genetic mechanism is not fully clear, however, four maturity loci E1, E2, E3 and E4 have been molecularly identified. In this report, cultivars were selected with various photoperiod sensitivities from different ecological zones, which covered almost all maturity groups (MG) from MG 000 to MG VIII and MG X adapted from latitude N 18° to N 53°. They were planted in the field under natural daylength condition (ND) in Beijing, China or in pots under different photoperiod treatments. Maturity-related traits were then investigated. The four E maturity loci were genotyped at the molecular level. Our results suggested that these four E genes have different impacts on maturity and their allelic variations and combinations determine the diversification of soybean maturity and adaptation to different latitudes. The genetic mechanisms underlying photoperiod sensitivity and adaptation in wild soybean seemed unique from those in cultivated soybean. The allelic combinations and functional molecular markers for the four E loci will significantly assist molecular breeding towards high productivity.
