Microsclerotia of three melanin-deficient mutants of Verticillium dahliae formed malanin from (+)-scytalone, 1,8-dihydroxynaphthalene, catechol, and L-3,4-dihydroxyphenylalanine. The melanins formed from (+)-scytalone or 1,8-dihydroxynaphthalene resembled wild-type melanin chemically and ultrastructurally, whereas the melanins formed from catechol and L-3,4-dihydroxyphenlalanine were different. This suggests that scytalone and 1,8-dihydroxynaphthalene but no catechol or L-3,4-dihydroxyphenylalanine are natural intermediates of melanin biosynthesis in V. dahliae.
大丽轮枝菌三个黑色素缺陷型突变体的微菌核可利用（+）-紫草酮、1,8-二羟基萘、儿茶酚和L-3,4-二羟基苯丙氨酸形成黑色素。由（+）-紫草酮或1,8-二羟基萘形成的黑色素在化学和超微结构上类似于野生型黑色素，而由儿茶酚和L-3,4-二羟基苯丙氨酸形成的黑色素则有所不同。这表明紫草酮和1,8-二羟基萘而非儿茶酚或L-3,4-二羟基苯丙氨酸是大丽轮枝菌黑色素生物合成的天然中间体。
