A 125-member library of synthetic linear undecapeptides was prepared based on a previously described peptide H-K(1)KLFKKILKF(10)L-NH(2) (BP76) that inhibited in vitro growth of the plant pathogenic bacteria Erwinia amylovora, Xanthomonas axonopodis pv. vesicatoria, and Pseudomonas syringae pv. syringae at low micromolar concentrations. Peptides were designed using a combinatorial chemistry appr...

In this study, we used real-time quantitative PCR (RT-qPCR) to evaluate the expression of 32 genes of Xanthomonas axonopodis pv. citri related to pathogenicity and virulence that are also involved in copper detoxification. Nearly all of the genes were up-regulated, including copA and copB. Two genes homologous to members of the type II secretion system (xcsH and xcsC) and two involved in the de...

Amplified fragment length polymorphism (AFLP) was used to analyze the genetic diversity of 14 strains of Xanthomonas arboricola pv. pruni and seven strains of X. axonopodis pv. phaseoli, which are used in xanthan production studies. Relationships identified by the AFLP profiles were assessed for xanthan production capacity, geographical location and host plant. Strains were isolated from 10 dif...

Bu çalışmada, 2017 yılında Iğdır ilinde domateste verim ve kalite kaybına neden olan bakteriyel hastalık etmenleri araştırılmıştır. amaçla üretiminin yoğun olarak yapıldığı Aralık, Karakoyun, Tuzluca, Kasımcan, Oba Melekli ilçelerinde sürvey yapılarak hastalıklı bitki örnekleri toplanmıştır. İzolasyon çalışması sonucunda 98 bakteri straini elde edilmiştir. Strainlerin King B besiyerinde fluores...

Clusterbean [Cyamopsis tetragonaloba (L.) Taub is an arid and semi-arid legume crop belonging to the family leguminaceae. It a drought enduring leguminous because of its profound tap rooting system has high capability get well from water stress. Total fifty-nine varieties/genotypes clusterbean were screened under artificial Inoculation field conditions at College Research Farm, Agriculture, Bik...

Plants protect themselves from diverse potential pathogens by induction of the immune systems such as systemic acquired resistance (SAR). Most bacterial plant pathogens thrive in the intercellular space (apoplast) of plant tissues and cause symptoms. The apoplastic leaf exudate (LE) is believed to contain nutrients to provide food resource for phytopathogenic bacteria to survive and to bring ha...

A library of 66 cyclic decapeptides incorporating a Trp residue was synthesized on solid phase and screened against the phytopathogenic bacteria Pseudomonas syringae pv. syringae, Xanthomonas axonopodis pv. vesicatoria, and Erwinia amylovora. The hemolytic activity of these peptides was also evaluated. The results obtained were compared with those of a collection of Phe analogues previously rep...
