Isolation, expression, and functional analysis of the geranylgeranyl pyrophosphate synthase (GGPPS) gene from Liriodendron tulipifera.

Terpenoids are important secondary metabolites in plants and are involved in stress responses and pollinator attraction. Geranylgeranyl pyrophosphate synthase (GGPPS) is a key synthase in the 2C-methyl-D-erythritol-4-phosphate (MEP) pathway of terpenoid synthesis, catalyzing the synthesis of diterpenoids. Liriodendron tulipifera is a nectar plant in North America.

[Comparison of genetic diversity among five mating types of Liriodendron revealed by SSR markers].

The exploration of relationships between mating patterns and genetic diversity of progenies has theoretical and practical significance for both interspecies hybridization breeding and seed orchard management in tree species. Sixteen plants of Liriodendron chinense, L. tulipifera, and hybrid Liriodendron were chosen as the mating parents.
