【摘要】A full-length cDNA of GlFtsZ was isolated by screening the cDNA library of Gentiana lutea. Analysis of the deduced amino acid sequence encoded by GlFtsZ indicated that GlFtsZ protein possesses the typical conservative motifs existed in all FtsZ proteins. The existence of putative plastid transit peptide in its N-terminus suggested that GlFtsZ might function inside of plastids. With the deve- lopmental process of petals of Gentiana lutea, the expression of plastid division gene GlFtsZ declined gradually, whereas the expression of carotenoids biosynthesis gene Zds increased obviously; meanwhile, in contrast to the increment of carotenoids, the content of chlorophyll in petals decreased sharply. The chloroplasts turned into chromoplasts, and the color of petals also turned from green to golden. All of these results suggested that the expression of GlFtsZ is accompanied with the development and differentiation of plastids. 【总页数】6页(592-597)
