Stem or black rust of wheat, caused by Puccinia graminis Pers. f. sp. tritici Eriks. and Henn (Pgt), was the most feared and devastating disease of wheat at one time worldwide. The fear from stem rust was understandable because an apparently healthy looking crop about 3 weeks prior to harvest could reduce to a black tangle of broken stems and shriveled grain by harvest. The disease has been co...
Distribution and Characterization of AKT Homologs in the Tangerine Pathotype of Alternaria alternata
One of the most important diseases pea is caused by Pea seed-borne mosaic virus (PSbMV), which has a relatively wide host range. Since there are few varieties with resistance against virus, and spraying insecticides not very effective, determination disease pathogen in seeds important. Inoculum prepared from showing typical symptoms mild on Chenopodium amaranticolor C. quinoa , but several chlo...
The Gram-negative bacterial genus Xanthomonas includes numerous infra-specific taxa known as pathovars, which are defined primarily on host range and disease symptoms. With the advent of molecular sequence data, many pathovars have been transferred from X. campestris into other species to better harmonise taxonomy phylogeny. We performed whole-genome shotgun sequencing pathotype strains followi...
IbeA (invasion of brain endothelium), which is located on a genomic island termed GimA, is involved in the pathogenesis of several extraintestinal pathogenic E. coli (ExPEC) pathotypes, including newborn meningitic E. coli (NMEC) and avian pathogenic E. coli (APEC). To unravel the phylogeny of GimA and to investigate its island character, the putative insertion locus of GimA was determined via ...
Lineages of hypervirulent Aeromonas hydrophila (vAh) are the cause of persistent outbreaks of motile Aeromonas septicemia in warm-water fishes worldwide. Over the last decade, this virulent lineage of A. hydrophila has resulted in annual losses of millions of tons of farmed carp and catfish in the People's Republic of China and the United States (US). Multiple lines of evidence indicate US catf...
