初步遗传分析表明，该突变性状相对于受体亲本莆大麦2号的二棱为隐性，是穗棱型变异的一种，受一隐性基因prb控制。

Null mutant Δmnh6 produced appeared offwhite hyphae, showed reduction in growth, conidiation and appressorium formation, and also showed reduction in appressorium turgor pressure. And the hyphae were more readily wettable by a solution containing SDS and EDTA and more easily digested by fungal cell-wall-digesting enzymes. The appressoria produced by Δmnh6 mutants showed diminished host penetration and the infectious hyphae of Δmnh6 mutants showed reduced in planta growth. Targeted deletion of mnh6 resulted in the greatly reduced virulence capacity to barley and rice CO39 in infection assays.

突变子Δmnh6的菌落形态不同于野生型GUY11，菌落呈灰白色，菌丝稀疏，生长速度变慢，产孢菌丝细胞壁的溶剂疏水性消失，菌丝细胞壁容易被细胞壁降解酶降解，产孢减少，孢子形态变得细长，孢子的附着胞形成率降低，附着胞的膨压降低，附着胞对寄主植物表面的穿透能力减弱，侵入后生长速度减慢，喷雾接种后对大麦和水稻CO39的致病性消失。mnh6基因重新引入Δmnh6后，突变子的表型恢复。
