The intramolecular proton transfers of phenol hydroxyl group to quinonoid carbonyl in Elsinochrome A are very sensitive for the change of molecular structure.

痂囊腔菌素A的酚羟基与醌羰基之间的分子内质子传递对其的结构变化最为敏感。7。

The results showed that the conidia of the RNAi transformant accumulated more trehalose, lost viability more slowly during prolonged storage and showed reduced heat shock sensitivity than the wild type, and the overexpression transformant has reverse results. These results indicate that neutral trehalase in M.anisopliae control trehalose concentration via degradation of trehalose, and indirectly influnce the viability of conidia during prolonged storage and the resistance to heat stress.

以上研究结果表明，金龟子绿僵菌CQMa102孢子体内海藻糖是由中性海藻糖酶降解的，海藻糖含量与耐储性和耐热性具有正相关性，中性海藻糖酶在虫生真菌金龟子绿僵菌孢子中的生理功能是通过降解分子内海藻糖调控海藻糖含量，从而影响其对不良环境的抗性，如储藏性、耐热性。
