Abstract

In this study DNA sequence data was used to characterize 290 Fusarium strains isolated during a survey of root colonizing endophytic fungi of agricultural and nonagricultural plants in Northern Kazakhstan. The Fusarium collection was screened for species identity using partial translation elongation factor 1-α ( TEF1 ) gene sequences. Altogether , 16 different Fusarium species were identified , including eight known and four novel species, and the discovery of the phylogenetically divergent F. steppicola lineage. Isolates of the four putatively novel fusaria were further analyzed phylogenetically with a multilocus dataset comprising partial sequence of TEF1 , RNA polymerase II largest ( RPB1 ) and second-largest ( RPB2 ) subunits, and calmodulin ( CaM ) to assess their genealogical exclusivity. Based on the molecular phylogenetic and comprehensive morphological analyses, four new species are formally described herein : F. campestre , F. kazakhstanicum , F. rhizicola and F. steppicola .
