Popis: | A novel yeast-like species was isolated from the rhizosphere of tobacco root collected in Guizhou province, China. Sequence analysis of the large subunit (LSU) rDNA gene indicates that the isolate represents a novel species and most closely related to Meira siamensis. The phylogenetic analysis based on the Internal Transcribed Spacer (ITS) rDNA gene also confirmed the placement of the novel species within Meira. However, the novel species differs from M. siamensis by 9.1% bp difference in the LSU rDNA sequence region and also in terms of physiological characteristics as compared to other species. This species is proposed as M. nicotianae sp. nov. Co-incubation of M. nicotianae strain CY-1 and tobacco plantlets demonstrates that this fungal strain can promote growth of tobacco plant. Scanning electron micrographs and other morphological illustrations along with phylogenies are presented in this paper. |
