Abstract

The ubiquitous distribution of Nigrospora fungi in the mycobiota of cereal grain in Russia has been established. Fourteen Nigrospora strains using phylogenetic analysis of ITS, tub, and TEF loci were identified as N. gorlenkoana, first detected in Russia. Morphological characteristics of N. gorlenkoana strains were analyzed on various nutrient media. A wide temperature range of 15–25°C was optimal for the N. gorlenkoana growth. This observation causes the widespread occurrence of N. gorlenkoana in nature. The pathogenicity of N. gorlenkoana strains to cereal crops was shown. The fungal strains reduced length of wheat and barley seedlings on average 48 and 39% compared to the control, respectively.

Nigrospora gorlenkoana Novobr 的生理生化特性。发生在谷物上

摘要

黑孢子真菌在俄罗斯谷物真菌群中的普遍分布已经确定。通过对 ITS、tub和TEF位点进行系统发育分析， 14 个黑孢菌株被鉴定为N. gorlenkoana，首次在俄罗斯发现。对不同营养培养基上的N. gorlenkoana菌株的形态特征进行了分析。15–25°C 的宽温度范围最适合N. gorlenkoana 的生长。这一观察结果导致戈尔伦科阿纳猪笼草在自然界中广泛存在。N. gorlenkoana的致病性显示了谷类作物的菌株。与对照相比，真菌菌株使小麦和大麦幼苗的长度平均分别减少了 48% 和 39%。
