研究了豌豆3-磷酸甘油醛脱氢酶(GPD)的吡啶核苷酸依赖性。豌豆种子和幼苗在黑暗中萌发的GPD是DPN专一性的。在光照下的幼苗，在第10天后出现了TPN连接的GPD。这一新种定位于绿芽中，而不存在于根中。在黑暗中萌发的幼苗在转移到光下时产生TPN连接的GPD，光诱导的TPN连接的GPD从新形成的种子中消失。在植物从种子到种子的生命周期中，GPD从种子中的专性DPN依赖周期性地变化到地上部的多组分系统，与DPN或TPN一起发挥作用，并在新形成的种子中回到专性DPN依赖中。
The pyridine nucleotide dependence of glyceraldehyde 3-phosphate dehydrogenase (GPD) was investigated throughout the life cycle of pea plants.The GPD of seeds and seedlings germinated in the dark was DPN-specific. In seedlings exposed to light, there appeared after the tenth day, a TPN-linked GPD. This new species of GPD was localized in the green shoot and was absent from roots. Seedlings germinated in the dark developed the TPN-linked GPD upon transfer to light.The light-induced TPN-linked GPD disappeared from the newly formed seed. In the life cycle of the plant from seed to seed, the GPD changes cyclically from obligate DPN dependence in the seed, to a multicomponent system in the shoot, functional with either DPN or TPN, and back to obligate DPN dependence in the newly formed seed.
