Phenotypic measures of the strains used in this study.

Foot and root rot severity measured with McKinney index (0–100) a and emergence b tested on durum wheat cv Claudio; number of spikes infected at 14 days above the point of inoculation [38]c ; hydrophobicity of the mycelium measured in seconds needed before absorption of a 20 µ l water dropd; millions of conidia produced in CMC medium inoculated with 103 conidia after 5 days growthe; percentage of germination of conidia after 4 hours on CMf; percentage of germinating conidia at 8 hrs (all mutants showed a delayed germination but no significant difference in the number of germinating conidia was observed)g; DON production in toxin inducing liquid medium corrected for mg of dry weight after 8 days culturingh; polygalacturonase enzyme activity measured with a diffusion assay on agarose gel (“cup plate”); measurements of pectolytic enzyme activity in diameter (mm) corrected by dry fungal biomass (mg)i. * PAll values are followed by SD. Significant differences compared to respective wild type are marked with an asterisk.以麦金尼指数（McKinney index，0–100）a测定硬粒小麦（durum wheat）品种Claudio的根腐与基腐严重度及出苗情况b；接种后14天于接种点上方统计的发病穗数c（参考文献[38]）；菌丝疏水性d：以20 μL水滴被菌丝体吸收所需的时长（秒）表征；以10³个分生孢子接种于羧甲基纤维素（CMC）培养基，培养5天后产生的分生孢子产量（单位：百万）e；分生孢子在CM培养基（CM medium）上培养4小时后的萌发率f；培养8小时后的分生孢子萌发率g（所有突变体均表现出发芽延迟，但萌发孢子总数无显著差异）；于毒素诱导液体培养基中培养8天后的脱氧雪腐镰刀菌烯醇（DON）产量h，结果以每毫克真菌干重校正；采用琼脂糖凝胶扩散法（"cup plate"）测定的多聚半乳糖醛酸酶（polygalacturonase）活性；以菌落直径（mm）表征的果胶酶活性，经真菌干生物量（mg）校正i。* 所有数值均附带标准差（SD）。与对应野生型存在显著差异的结果以星号（*）标记。
