AIMS To investigate the aetiology of seed and boll rot of cotton grown in South Carolina (SC). METHODS AND RESULTS Bacteria were isolated from diseased locules of cotton bolls collected in a field in SC, USA and tested for the ability to cause comparable disease symptoms in greenhouse grown cotton fruit. Spontaneously generated rifampicin-resistant (Rif(r)) mutants of the isolates were used i...

Bacterial antagonists are effective as an alternative to synthetic bactericides in the control of potato soft rot. The use bioagents reduces application bactericides, which harmful humans and environment. However, mechanisms some bioagents, such fungi bacteria, not yet understood. This paper reviews current situation rot, biological controls, antagonistic their mechanisms, strategies future dir...

The sheath rot rice disease is known to be associated Pseudomonas fuscovaginae and a recent study on the symptomatic of revealed that this bacterial pathogen abundant in highland ecology cultivation Burundi. From asymptomatic samples rice, collection isolates culturable microbiome have been carried out. A comparison between total was made. Phenotypic assays vitro were performed after identifica...

Among the most devastating bacterial diseases of plants, soft rot provoked by Dickeya spp. cause crop yield losses on a large range of species with potato being the most economically important. The use of antibiotics being prohibited in most countries in the field, identifying tolerance genes is expected to be one of the most effective alternate disease control approaches. A prerequisite for th...

O'Bannon and Taylor reported that carrot disks on 1% agar were suitable for culturing Pratylenchus brachyurus (4). We found that they are suitable also for Pratylenchus vulnus, and easier to prepare than the alfalfa tissue we have used in the past (3). Our observations on carrot disks during the last 3 years may be useful to others. Initially, many of the carrot disks rotted, and a variety of s...

Klebsiella pneumoniae (associated with bacterial pneumonia) was previously isolated from Nezara viridula, a significant vector of cotton boll-rot pathogens. We provide the first annotated genome sequence of the cotton opportunistic strain K. pneumoniae 5-1. This data provides guidance to study the bases of cotton pathogenesis by bacteria associated with vectors.

Dickeya zeae is an emerging rice (Oryza sativa) pathogen causing bacterial foot rot. Related pathogens affect maize (Zea mays) and potato (Solanum tuberosum) and a variety of important ornamental and floral plants. Here, we present the draft genome sequence of D. zeae DZ2Q, an isolate obtained from rice grown in Italy.

Ralstonia solanacearum is a globally distributed plant pathogen that causes bacterial wilt diseases of many crop hosts, threatening both sustenance farming and industrial agriculture. Here, we present closed genome sequences for the R. solanacearum type strain, K60, and the cool-tolerant potato brown rot strain R. solanacearum UW551, a highly regulated U.S. select agent pathogen.
