title: Two genes for the high mobility group protein HMG-Y are present in the genome of Canavalia gladiata D.C.
abstract: Two cDNAs encoding high-mobility-group (HMG) proteins that correspond to animal HMG-Y proteins were isolated from maturing seeds of Canavalia gladiata D.C. The deduced amino acid sequences of these cDNAs showed similarity to other plant HMG-I/Y proteins reported to date. The mRNAs for the HMG-Y proteins were detected in leaves, stems, roots, pods and seeds of C. gladiata. The level of the mRNA was high in the maturing seeds of 30 days after flowering and 2-day germinated seeds. Two genomic clones were isolated from DNA of C. gladiata and both were shown to represent single-copy genes consisting of two exons and one intron. This is the first report of the genomic sequences for HMG-I/Y protein in plants.
