Expressions of Ginlfy and GinNdly gene were studied by northern blotting in different organs and stages of Ginkgo Biloba. Ginlfy gene was expressed in different organs such as root, stem, leaf of juvenile tree, male tree and female tree, and in different stages of male flower bud and female flower bud. It was inferred that Ginlfy gene could be expressed constitutionally. GinNdly gene was only expressed in leaf of juvenile tree, male tree and female tree and in different stages of male flower bud and female flower bud, while GinNdly gene was not expressed in the other organs. Therefore it was thought that GinNdly gene could be expressed differentially and be a close relation to development of flower.
通过Northern印迹法研究了银杏叶中Ginlfy和GinNdly基因在不同器官和不同发育阶段的表达情况。Ginlfy基因在幼树、雄树和雌树的根、茎、叶等不同器官以及雄花芽和雌花芽的不同发育阶段均有表达。由此推断，Ginlfy基因可能组成性表达。GinNdly基因仅在幼树、雄树和雌树的叶片以及雄花芽和雌花芽的不同发育阶段表达，而在其他器官中不表达。因此，认为GinNdly基因可能差异表达，且与花的发育密切相关。
