Three MADS-box genes of Hevea brasiliensis expressed during somatic embryogenesis and in the laticifer cells.
Three MADS-box genes, designated HbMADS1, HbMADS2 and HbMADS3, were isolated from Hevea brasiliensis. HbMADS1, HbMADS2 and HbMADS3 encode polypetides consisting of 245, 217 and 239 amino acids, respectively, containing conserved MADS-box motifs at N-terminus. Transcription pattern analysis revealed that three MADS-box genes had highly transcription in the laticifer cells. The transcriptions of HbMADS1and HbMADS3 were induced in the laticifer cells by jamonic acid, while HbMADS2 was not induction by jamonic acid. Ethephone is not effective in inducing their expression. The three genes were differentially expressed during somatic embryogenesis of rubber tree. Characterization of HbMADSs will attribute to understand their possible function in rubber tree.
