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.

    Results of transcriptome analyses suggest that expansin genes play an active role in seed development and yield, but gain- or loss-of-function studies have not yet elucidated the functional role(s) of the expansin gene(s) in these processes. We have overexpressed a sweetpotato expansin gene (...

    Background and Aims: The major economic product of Hevea brasiliensis is a rubber-containing cytoplasm (latex), which flows out of laticifers (latex cells) when the bark is tapped. The latex yield is stimulated by ethylene. Sucrose, the unique precursor of rubber synthesis, must cross the plasma...

    Rubber (cis-1,4-polyisoprene), an important raw material for many industrial uses, is synthesized in the latex of Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg. We postulated that the genes uniquely or preferentially expressed in the latex may be important for rubber biosynthesis. We...
