The 5S ribosomal RNA (rRNA) genes in eukaryotes may occur either interspersed with the other rRNA genes in the ribosomal DNA (rDNA) repeat, or in separate tandem arrays, or dispersed throughout the genome. In Pythium species and in several related Oomycetes, polymerase chain reaction (PCR) amplification of the nontranscribed spacer (NTS) region with one primer specific for the 5S gene revealed,...

Phragmites australis (Cav.) Trin. ex Steud. die-back is a widely-studied phenomenon that was first discovered in northern Europe and that, until recently, was almost unknown in the Mediterranean basin. It has been described as a complex syndrome affecting reed populations leading to their retreat and decline, with significant impacts on valuable ecosystem services. Among the factors that cause ...

In this study, we present the draft genome sequence of the bacterial strain Pseudomonas chlororaphis PCL1601. This bacterium was isolated from the rhizosphere of healthy avocado trees and displayed antagonistic and biological control activities against different soilborne phytopathogenic fungi and oomycetes.

Serratia marcescens MSU97 was isolated from the Guayana region of Venezuela due to its ability to suppress plant-pathogenic oomycetes. Here, we report the genome sequence of MSU97, which produces various antibiotics, including the bacterial acetyl-coenzyme A (acetyl-CoA) carboxylase inhibitor andrimid, the chlorinated macrolide oocydin A, and the red linear tripyrrole antibiotic prodigiosin.

Brown algae are the predominant primary producers in coastal habitats, and like land plants are subject to disease and parasitism. Eurychasma dicksonii is an abundant, and probably cosmopolitan, obligate biotrophic oomycete pathogen of marine brown algae. Oomycetes (or water moulds) are pathogenic or saprophytic non-photosynthetic Stramenopiles, mostly known for causing devastating agricultural...

ABSTRACT The scientific community has made a persuasive case to increase funding for genomic sequencing of microbial plant pathogens, and a number of objective criteria were developed to guide the selection of sequencing targets. However, this task still is complicated for fungi and Oomycetes, which are extremely diverse evolutionarily. Lack of a definite target number of organisms to be sequen...

Potato pectin falls to Phytophthora infestans is a plant oomycete pathogen that drove the potato famines of 1800s and continues afflict fields today. The polysaccharide makes up about third cell wall in potatoes. Sabbadin et al . identified family lytic monooxygenases (LMPOs) cleave are upregulated P. during infection. Silencing relevant LMPO gene successfully inhibited infections. These findin...
