Abstract: A full-length cDNA encoding sucrose synthase was isolated from the tropical epiphytic CAM orchid Mokara Yellow. The cDNA is 2748 bp in length containing an open reading frame of 2447 bp encoding 816 amino acids with a predicted molecular mass of 93.1 KDa. The deduced amino acid sequence of M. Yellow sucrose synthase (Msus1) shares more than 80% identity with those from other monocotyledonous plants. The sucrose synthase gene was demonstrated to encode a functional sucrose synthase protein by expression as recombinant protein in Escherichia coli. Northern blot analysis showed that the expression pattern of Msus1 mRNA is tissue specific with highest levels in strong sinks such as expanding leaves and root tips, but not detectable in mature leaves and flowers. Incubation with sugars resulted in a significant increase in the steady-state Msus1 mRNA levels in shoots of seedlings.
