The amino acid region from 448-517 of CAMTA3 transcription factor containing a part of the TIG domain represses the N-terminal repression module function.

ABSTRACT: CAMTA3, a Ca²⁺-regulated transcription factor, is a repressor of plant immune responses. A truncated version of CAMTA3; CAMTA3³³⁴ called N-terminal repression module (NRM), and its extended version (CAMTA⁴⁴⁷), which include the DNA binding domain, were previously reported to complement the camta3/2 mutant phenotype. Here, we generated a series of CAMTA3 truncated versions [the N-terminus (aa 1-517), C-terminus (aa 517-1032), R1 (aa 1-173), R2 (aa 174-345), R3 (aa 346-517), R4 (aa 517-689), R5 (aa 690-861) and R6 (aa 862-1032)], expressed in camta3 mutant and analyzed the phenotypes of the transgenic lines. Interestingly, unlike CAMTA⁴⁴⁷, extending the N-terminal region to 517 aa did not complement the camta3 phenotype, sugges
