Coordinate Production of Hydroxyphaseollin and the Yellow-Fluorescent Compound PA_k in Soybeans Resistant to Phytophthora megasperma var. sojae. N. T.

Eight incompatible soybean-Phytophthora megasperma var. sojae combinations resulted in higher rates of production of PA_k and hydroxyphaseollin (HP) than did eight compatible combinations. The two compounds were produced at rates similar to each other in all combinations, which indicated that they may be under coordinate metabolic control in the inoculated soybean plants.
