使用 26 种化学合成的 CLAVATA3/ESR (CLE) 肽（对应于 31 个拟南芥 CLE 基因的预测产物），我们研究了拟南芥和水稻中的 CLE 肽功能。用一些 CLE 肽处理会抑制水稻和拟南芥的根伸长。它还减少了拟南芥中茎尖分生组织的大小，但在水稻中却没有。数据库搜索揭示了水稻基因组中的 47 个假定的 CLE 基因以及一些 CLE 基因中的多个 CLE 结构域，表明这些植物中存在多种 CLE 功能。
Using 26 chemically synthetic CLAVATA3/ESR (CLE) pep-tides, which correspond to the predicted products of the 31 Arabidopsis CLE genes, we investigated the CLE peptide function in Arabidopsis and rice. Treatment with some CLE peptides inhibited root elongation in rice as well as in Arabidopsis. It also reduced the size of the shoot apical meristem in Arabidopsis but not in rice. Database searches revealed 47 putative CLE genes in the rice genome and multiple CLE domains in some CLE genes, indicating diverse CLE function in these plants.
