从拟南芥的花序特异性基因的基因组和cDNA克隆的分离和表征。这些基因在基因组中串联在一个10 kb的片段上。这些基因的表达在发育和器官特异性模式中协调调节。它们主要在花发育后期的花药中表达。所编码的基因产物的一级结构表现出相当的功能，包括在N-末端区域的疏水结构域，然后是重复的富含甘氨酸的基序。几乎没有同源性之间观察到的三个基因的富含甘氨酸的结构域或与先前描述的富含甘氨酸的蛋白质从其他植物物种。
Genomic and cDNA clones for three inflorescence-specific genes from Arabidopsis thaliana were isolated and characterized. The genes are tandemly organized in the genome on a 10 kb fragment. The expression of these genes is coordinately regulated in a developmental and organ-specific pattern. They are expressed predominantly in anthers at the later stage of flower development. The primary structure of the encoded gene products exhibits comparable features consisting of a hydrophobic domain at the N-terminal region followed by repeated glycine-rich motifs. Little homology is observed either between the glycine-rich domain of the three genes or with previously described glycine-rich proteins from other plant species.
