✦ Synopsis

Naturally occurring 4'-dihydrophaseic acid (DPA) has been isolated from mature, non-imbibed bean seed. The concentrations of abscisic acid (ABA), phaseic acid (PA) and DPA in the seed were estimated to be 0.06, 0.11 and 5.95 mg/kg dry wt., respectively. The results suggest that DPA is a major inactivation product of ABA in this tissue. The possible pathway from ABA to DPA is discussed.

Rhamnogalacturonan I (RG-I), a pectic polysaccharide isolated from the walls of suspension-cultured sycamore cells, was shown by glycosyl-residue composition analysis to contain D-glucosyluronic acid (GlcpA) residues (1 mol%) and 4-O-methyl-D-glucosyluronic acid (4-O-Me-GlcpA) residues (0.5 mol%). T
