| 1 | LATERAL ROOTLESS2, a Cyclophilin Protein, Regulates Lateral Root Initiation and Auxin Signaling Pathway in Rice显示文摘Dear Editor, Cyclophilins (CYP) are a class of highly conserved peptidyl-prolyl cis-trans isomerases (PPlases) that play important roles in various biological processes in eukaryotes (reviewed in Romano et al.(2004)).In higher plants,a conserved single domain cyclophilin has been identified as a novel component of the auxin signaling pathway by analyzing the tomato diageotropica (dgt) mutant (Ivanchenko et al.,2006;Oh et al.,2006).The dgt mutant displays a lateral-rootless and auxin-resistant phenotype (Ivanchenko et al.,2006).Further studies revealed that mutations in the DGT-like genes of Physcomitrella patens also exhibited an auxin-resistant phenotype,suggesting a conserved role of DGT-like proteins in auxin signaling.Moreover,mutation in PpDGT gene suppresses the auxin hypersensitive phenotype conferred by the overexpression of the auxin receptor gene PpAFB2,indicating that PpDGT acts downstream of PpAFB2 (Lavy et al.,2012). | Huakun Zheng Suiuan Li Bo Ren Jian Zhang Masahiko Ichii Shin Taketa Yuezhi Tao Jianru Zuo Hua Wang | 2013 | Molecular Plant2013，6，5： | 4 |
