Two morphological groups derived from Clonostachys cylindrospora and their relationship to trans-4-hydroxy-(L)- proline productivity
1995
Thetrans-4-hydroxy-(l)-proline productivity and morphological characteristics of strains isolated from two different conidium-producing structures inClonostachys cylindrospora were compared.trans-4-Hydroxy-(l)-proline was found to be produced only by strains originating from conidia on penicillate conidiophores, not by strains originating from conidia on verticillate conidiophores. Strains from each conidium-producing structure were also segregated by morphological properties; i.e., the amount of aerial hypha produced on modified Weitzman's agar, production of water-soluble yellow pigment in potato-dextrose agar, the primarily formed conidium-producing structures, and sclerotium formation. These phenomena indicate that morphological characteristics and metabolite productivity are correlated and destined at the stage of conidial production inC. cylindrospora.
