title: Developmental regulator Le.CDC5 of the mushroom Lentinula edodes: analyses of its amount in each of the stages of fruiting-body formation and its distribution in parts of the fruiting bodies.
abstract: Immunoblot analysis of Le.CDC5 (842 amino acid residues), the expressed product of the cDNA of Le.cdc5 gene that has been previously reported to be most actively transcribed in primordia and small immature fruiting bodies of the basidiomycete Lentinula edodes, showed that the primordia, immature fruiting bodies and mature fruiting bodies contain similar amounts of Le.CDC5 protein. This indicates that the Le.CDC5 protein molecules synthesized in the beginning and early stage of fruiting-body formation remains in mycelial tissues even after small immature fruiting bodies developed and matured. Immunohistochemical analysis showed that Le.CDC5 is present everywhere in the mycelial tissues of immature fruiting body, but prehymenophore, the border between pileus and stipe, and the bottom of stipe seem likely to contain larger amounts of Le.CDC5. Within the hymenophore of mature fruiting body, the hymenium (in/on which a large number of basidia and basidiospores are formed) contains the Le.CDC5 most exclusively.
