During surveys in cowpea fields of Marand County, East Azerbaijan province, Iran, in the summer of 2013, a suspected bacterial disease was observed on cowpea leaves as tan spots and interveinal necrotic lesions surrounded by chlorotic margins. The disease was of high incidence where some fields had been fully destroyed and severity of the disease in some fields had reached up to 70%. Gram‐positive, yellow‐pigmented, coryneform bacteria were isolated from infected leaves. Pathogenicity of isolates was confirmed on 20‐day‐old cowpea (cv. Khoy) plants, and they were identified as Curtobacterium flaccumfaciens pv. flaccumfaciens based on biochemical test results confirmed using specific PCR primers. This is the first report of C. flaccumfaciens pv. flaccumfaciens, the causal agent of cowpea bacterial wilt in Iran.

“…The best-studied pathovar, C. flaccumfaciens pv. flaccumfaciens , is the causal agent of bacterial wilt in dry beans worldwide with reports on five continents (Wood and Easdown, 1990; Harveson et al, 2006; EPPO, 2011; Soares et al, 2013; Osdaghi et al, 2015a). The disease harbors a high degree of genetic and phenotypic diversity (Hedges, 1926; Conner et al, 2008) even within a single host (Agarkova et al, 2012).…”

Evidence for Ecological Flexibility in the Cosmopolitan Genus Curtobacterium

et al. 2016

Assigning ecological roles to bacterial taxa remains imperative to understanding how microbial communities will respond to changing environmental conditions. Here we analyze the genus Curtobacterium, as it was found to be the most abundant taxon in a leaf litter community in southern California. Traditional characterization of this taxon predominantly associates it as the causal pathogen in the agricultural crops of dry beans. Therefore, we sought to investigate whether the abundance of this genus was because of its role as a plant pathogen or another ecological role. By collating >24,000 16S rRNA sequences with 120 genomes across the Microbacteriaceae family, we show that Curtobacterium has a global distribution with a predominant presence in soil ecosystems. Moreover, this genus harbors a high diversity of genomic potential for the degradation of carbohydrates, specifically with regards to structural polysaccharides. We conclude that Curtobacterium may be responsible for the degradation of organic matter within litter communities.

A new orange variant of Curtobacterium flaccumfaciens pv. flaccumfaciens was isolated from seeds of common bean cv. Daneshkadeh and Dehghan stored in the seed banks in Khomein Bean Research Station, and field plants (cv. Local Khomein) in Arak, Iran. The pathogenicity of the isolates was confirmed on 5‐ to 7‐day‐old seedlings of cv. Daneshkadeh. Marginal necrosis and interveinal chlorosis on first trifoliate leaves were observed 10–15 days after inoculation. Amplification of 306 bp fragment of orange‐pigmented strains using CffFOR2‐ and CffREV4‐specific prime pair characterized them as C. flaccumfaciens pv. flaccumfaciens. Although the yellow‐pigmented variant of the causal agent was previously reported on cowpea, this is the first report of orange variant of C. flaccumfaciens pv. flaccumfaciens causing bacterial wilt on common bean in Iran.
