选项分析：

A选项：Correct. 本选项在语法和逻辑上均是正确的。

B选项：介词短语as being major importance需改为不定式短语to be of major importance。这点考查了不定式和ing的区别。用之于本题，由于变化部分是宾语部分，所以我们应根据其主句谓语动词的约束力来判断。显然地，acknowledge是看法类动词，且是被动语态，宾语部分需用不定式短语。

C选项：句首的after long years of indifferent reception by the scientific community（被科学团体所不接受的）修饰的是划线部分的主语。在逻辑上，能被科学团体所不接受的只能是某种工作（Barbara McClintock‘s subtle work），不能是it。

D选项：能被科学团体所不接受的只能是某种工作（Barbara McClintock‘s subtle work），而不能重要性（importance）。

E选项：本选项错误同(D)。
