There are few studies on inheritance and behavior of nucleoli in soybean. Yamaha and Sinoto (1925) reported the behavior of nucleoli in somatic mitosis of 30 species of higher plants including Glycine max [Soja]. Palmer and Heer (1976) observed one large nucleolus and six small nucleoli in a 40-chromosome plant from the st4 st4 synaptic mutant. Folsom and Peterson (1984), in ultrastructural studies of soybean embryo sacs, noted that a micronucleo-lus often was associated with the nucleolus of an egg cell.
