These results corresponded to a higher lignin content measured by the Klason method and stem strength and a lower lodging index in H4564 than in C6001 at the heading and milky stages. Therefore, the TaCM mRNA levels, protein levels, and enzyme activity in developing wheat stems were associated with stem strength and lodging index in these two wheat cultivars.

马庆虎研究组分离了在小麦茎秆中高度表达的木质素合成关键酶基因-咖啡酸甲基转移酶基因，通过生化和转基因分析证明COMT 在控制松柏醇型木质素上发挥着重要作用，COMT基因的表达在抗倒伏小麦生长发育后期明显高于易倒伏品种，这种基因的高表达进一步促进了COMT酶蛋白和酶活力的提高，并增强了木质素的合成。
