Background & Aim: The aim of this study was to assess the antifungal effect of the watercress extract on the growth of Fusarium solani, the causal agent of potato dry rot. Experimental:  This research was done in a completely randomized design with three concentrations and four replicates on potato dextrose agar (PDA) culture medium. Results: Results of this study indicated that all ...

Goal. To evaluate and select potato varieties of domestic selection, resistant against the causative agents cancer — Synchytrium endobioticum (Schilb.) Perc, phomous rot Phoma exigua var. (Desm.), alternariosis Alternaria solani (Ell. & Mart.) alternata (Fries) Keissler. improve promising for introduction in seats these diseases. Methods. Laboratory evaluation on artificial infectious backgroun...

Development of protection tools targeting Dickeya species is an important issue in the potato production. Here, we present the identification and the characterization of novel biocontrol agents. Successive screenings of 10,000 bacterial isolates led us to retain 58 strains that exhibited growth inhibition properties against several Dickeya sp. and/or Pectobacterium sp. pathogens. Most of them b...

Endophytes are microbes and fungi that live inside plant tissues without damaging the host. Herein we examine the dynamic changes in the endophytic bacterial community in potato (Solanum tuberosum) tuber in response to pathogenic infection by Pectobacterium atrosepticum, which causes soft rot in numerous economically important crops. We quantified community changes using both cultivation and ne...

Effluent from electroplating industry involved in copper plating and other metal polishing work contain various heavy metal(Cu, Fe, Ni, Pb, Mn and Zn) which have severe adverse effect on health . The present work analyzes heavy metal present in plating shops for a period of one year. Highest copper metal concentration (27.60mg/L) was observed during post monsoon at site AB-5, least copper metal...

To enhance plant protection against phytopathogens, we constructed a fusion gene (SAP) for the simultaneous production of snakin-1 (SN1) and defensin-1 (PTH1) cysteine-rich antimicrobial proteins originally identified in potato. Prior to in vivo evaluation of antimicrobial activity, SAP produced in Escherichia coli was tested in in vitro against four phytopathogenic microorganisms. SAP exhibite...

In this study, we characterized a putative Flp/Tad pilus-encoding gene cluster, and we examined its regulation at the transcriptional level and its role in the virulence of potato pathogenic enterobacteria of the genus Pectobacterium. The Flp/Tad pilus-encoding gene clusters in Pectobacterium atrosepticum, Pectobacterium wasabiae and Pectobacterium aroidearum were compared to previously charact...
