| 中文摘要: |
| 格氏梅拉菌Meira geulakonigii最早是在柑桔锈螨病的枯枝中发现的，它是一种担子菌类酵母样无性态真菌，归属于黑粉菌纲外担子菌亚纲。目前仅了解这种真菌在植物中的生长状态，关于它的宿主范围、区域分布和生长特性依然知之甚少。首次从竹子中分离了两株新的Meira geulakonigii菌株（PM1和PM2），并且更深一步地描述了他们的生理特性，尤其着重表述了菌丝体的独特生长现象。与先前报导的两株M. geulakonigii 菌株PFS004和AS004相比较，PM1和PM2在分子系统上与AS004更相近，而生理现象与PFS004更相似。这两株菌株的成功分离可能有助于毛竹中Meira真菌菌丝体形成和功能的进一步研究。 |
| 英文摘要: |
| The genus Meira originally discovered from cadavers of the citrus rust mite contains anamorphic basidiomycetous yeast-like fungi belonging to the Exobasidiomycetidae of the Ustilaginomycetes. Although their endophytic nature in plants is later verified, the host range, regional distribution and growth characteristics of Meira species in plants are still poorly understood. In this study, two new strains (PM1 and PM2) of Meira geulakonigii, the type species of Meira, were isolated from bamboo for the first time. They were physiologically and morphologically characterized and compared with two M. geulakonigii isolates PFS004 and AS004 which were reported previously. Strains PM1 and PM2 exhibited different hypha formation ability. They were closer to AS004 molecular-phylogenetically but closer to PFS004 physiologically. These two isolates are possibly valuable for further studies on hypha formation and functions of Meira species in bamboo. |
