摘要
Dear Editor,It is well established that local intercellular signaling net-works control cell identity and activity.Secreted peptides have been found to play a central role in this capacity in plants(Matsubayashi and Sakagami,2006;Meng et al.,2010;Meng,2012).CLEL,which is the term for CLE(CLV3/ESR-related)-Iike peptides(also previously named as RGFs for root growth fac-tors by Matsuzaki et al.(2010)),regulate root growth pattern and lateral root development in Arabidopsis(Matsuzaki et al.,2010;Meng et al.,2012).CLEL peptide precursors contain an N-terminal signal peptide(hydrophobic patch),a diverse vari-able region.
