在产孢期，佛罗里达侧耳的漆酶活性下降到最低水平，但同工酶的数量增加。内源性漆酶底物特别是在孢子柄的鳃结构中被检测到，在体外实验中它竞争性地抑制了该酶对愈创木酚的氧化。鳃结构中漆酶底物的出现可能与产孢子现象有关。
During sporulation, laccase activity of Pleurotus florida decreased to a minimum level in spite of increase in the number of isozymes. An endogenous laccase substrate was detected especially in the gill structure of the sporophore, which competitively inhibited oxidation of guaiacol by the enzyme during in vitro assay. Appearance of the laccase substrate in the gill structure may be linked with the sporulation phenomenon.
