The rice Os02g0568200 was reported as cpt1 in 2005 [1] by researchers from the Japan.

Annotated Information

Gene Symbol

  • Os02g0568200 <=> cpt1


Function

  • The CPT1-dependent major phototropism of coleoptiles is achieved by lateral auxin translocation and subsequent growth redistribution.


Expression

  • The researchers isolated a mutant, named coleoptile phototropism1 (cpt1), from g-ray–mutagenized japonica-type rice (Oryza sativa). This mutant showed no coleoptile phototropism and severely reduced root phototropism after continuous stimulation. A map-based cloning strategy and transgenic complementation test were applied to demonstrate that a NPH3-like gene deleted in the mutant corresponds to CPT1.
