FIG. 1.
Polyacrylamide gel of fractionated extracts of intraradical and extraradical hyphae collected at 6 weeks after transplanting for comparison with poly-P standards. Lanes 1 to 3, synthetic poly-P standards of average chain lengths (15, 35, and 65 Pi units, respectively); lanes 4 to 6, TCA-, EDTA-, and PC-soluble fractions, respectively of, poly-Ps from intraradical hyphae; lanes 7 to 9, TCA-, EDTA-, and PC-soluble fractions, respectively, of poly-Ps from extraradical hyphae. This figure is not a quantitative comparison between intraradical and extraradical hyphae because the hyphal biomass taken for extraction was different.
