Abstract
Male gametophyte (pollen) isozyme profiles were compared with those of the sporophyte for nine enzyme systems. Sixty percent of the structural genes coding for these enzymes in the sporophyte were also found to be expressed by the gametophyte. All the genes tested were found to be expressed after meiosis, apparently transcribed and translated in the haploid gametophytes.
摘要
比较了雄配子体（花粉）同工酶谱与孢子体的同工酶谱，共涉及 9 种酶系统。在孢子体中编码这些酶的结构基因中有 60%也被发现由配子体表达。所有被测试的基因都在减数分裂后被发现表达，显然在单倍体配子体中转录和翻译。
