The Cellobiose Sensor CebR Is the Gatekeeper of Streptomyces scabies Pathogenicity
UNLABELLED A relatively small number of species in the large genus Streptomyces are pathogenic; the best characterized of these is Streptomyces scabies. The pathogenicity of S. scabies strains is dependent on the production of the nitrated diketopiperazine thaxtomin A, which is a potent plant cellulose synthesis inhibitor. Much is known about the genetic loci associated with plant virulence; ho...
متن کاملThe CebE/MsiK Transporter is a Doorway to the Cello-oligosaccharide-mediated Induction of Streptomyces scabies Pathogenicity
Streptomyces scabies is an economically important plant pathogen well-known for damaging root and tuber crops by causing scab lesions. Thaxtomin A is the main causative agent responsible for the pathogenicity of S. scabies and cello-oligosaccharides are environmental triggers that induce the production of this phytotoxin. How cello-oligosaccharides are sensed or transported in order to induce t...
متن کاملGlobal effects of virulence gene regulators in a Bacillus anthracis strain with both virulence plasmids.
Control of anthrax toxin and capsule synthesis, the two major virulence factors of Bacillus anthracis, has been associated with two regulatory genes, atxA and acpA, located on virulence plasmids pXO1 and pXO2, respectively. We used transcriptional profiling to determine whether atxA and/or acpA control genes other than those already described and to investigate functional similarities of the re...
متن کاملRegulation of Coronafacoyl Phytotoxin Production by the PAS-LuxR Family Regulator CfaR in the Common Scab Pathogen Streptomyces scabies
Potato common scab is an economically important crop disease that is characterized by the formation of superficial, raised or pitted lesions on the potato tuber surface. The most widely distributed causative agent of the disease is Streptomyces scabies, which produces the phytotoxic secondary metabolite thaxtomin A that serves as a key virulence factor for the organism. Recently, it was demonst...
متن کاملDiversity of Streptomyces strains causing potato scab disease in Hamedan province and their thaxtomin production potential
Hamedan province is one of the main potato growing areas in Iran. Potaoto scab disease caused by Streptomyces spp. is one of the prevalent and important diseases of potato in this provice. Potato tubers with symptoms of scab diseases including raised and deep or shallow pitted lesion were collected from potato growing area in this region. A total of 20 and 25 strains of Streptomyces were isolat...
