In this study, ITS–rDNA region was used to identify some anamorphic powdery mildews in Guilan province. According to the results, Erysiphe species on Vicia faba and Sesbania punicea showed 100% similarity to each other, however, without ITS sequence of holotype of E. sesbaniae it is impossible to make conclusion whether Vicia faba powdery mildew fungus actually belongs to E. sesbaniae or E. tri...
A recent survey of the entomofauna Davis Mountains in state Texas has revealed four new species genus Phytocoris Fallén (Miridae, Mirinae, Mirini): mcivor sp. nov. and schmitzi found on Quercus grisea Liebmann, marqua rileyi attracted to lights. Descriptions, habitus, genitalic images for are included herein. Further, habitus photographs known from county aid identification.
Novel species of fungi described in this study include those from various countries as follows: Australia: Apiognomonia lasiopetali on Lasiopetalum sp., Blastacervulus eucalyptorum on Eucalyptus adesmophloia, Bullanockia australis (incl. Bullanockia gen. nov.) on Kingia australis, Caliciopsis eucalypti on Eucalyptus marginata, Celerioriella petrophiles on Petrophile teretifolia, Coleophoma xant...
Mutation-induced recessive alleles (mlo) of the barley Mlo locus confer a leaf lesion phenotype and broad spectrum resistance to the fungal pathogen, Erysiphe graminis f. sp. hordei. The gene has been isolated using a positional cloning approach. Analysis of 11 mutagen-induced mlo alleles revealed mutations leading in each case to alterations of the deduced Mlo wild-type amino acid sequence. Su...
* This study targeted the fungal communities in the phyllosphere of Quercus macrocarpa and compared the fungal species richness, diversity and community composition among trees located within and outside a small urban center using recently developed 454 sequencing and DNA tagging. * The results indicate that the fungal phyllosphere communities are extremely diverse and strongly dominated by asc...
There are many naturally occurring variants at the Ml-a locus in barley that confer resistance to the powdery mildew fungus Erysiphe graminis f. sp. hordei. Since the Ml-a locus is bracketed by Hor-1 and Hor-2, genes that encode storage proteins in the endosperm, the Ml-a locus is amenable to fine structure analysis. Rare susceptible recombinants, as judged by exchange of flanking markers, were...
