6.The zinc content of pileus (25.1×10-4) was higher than that of stipe and volva (8.2 and 7.9×10-4 resp.) . Using "Zn as radiotracers, scintigraphy measurement (cpm/g) and radio autography were used to study absorption and distribution of "Zn in pileus, stipe and volva.
7.exitialis was higher than that of Phallotoxins (Phallacidin, Phallisin, P halloidin and Phalloin). But the content of Phallotoxins especially Phallacidin was gradationally higher from cap to stipe and to volva.
8.Aggregate fruit spicate, 10 cm long, stipe 2 cm long; follicles ellipsoid or ovoid, 1.2-1.5 cm long, apex with short and curved tip, outside inconspicuously sparsely lenticeled.
9.3.Cloning gene fragment expression specific in the opening stageTotal mRNA of fruit-body stipe is regarded as Tester and Driver respectively in egg stage and elongation stage to clone special expression gene fragment of fruit-body stipe in elongation stage by suppression subtraction hybridization. We got a gene fragment and sequence. We did not get the same sequence with our sequence by homology comparision in GENBANK.
10.Shiitake polysaccharides have been gained from cap , stipe and mycelia ofshiitake by means of water- extracted and alkali- extracted methods and two kinds of new polysaccharides, polysaccharide A(the water- extracted component) and polysaccharide B(the alkali- extracted component) , were purifiedfrom shiitake cap.
