| a morphologically ill-founded powdery mildew species, pleochaeta indica, is recognized as a phylogenetic species based on the analysis of the nuclear ribosomal dna sequences. | morphological characteristics of a powdery mildew fungus found on celtis australis in the indian himalayas coincided with those of pleochaeta indica, described from this tree species in india, as well with those of p. shiraiana, known to infect c. australis and other plant species in asia. this suggested that the original description of p. indica based on morphological patterns was not well founded and this taxon could be reduced to synonymy with p. shiraiana. however, phylogenetic analyses of t ... | 2006 | 17070029 |
