Dickeya and Pectobacterium spp. both cause blackleg soft rot of potato, which can be a yield-reducing factor to potato production. The purpose this study was examine the interaction between these two bacterial genera causing infection, subsequent disease development yield responses under field conditions. Analysis 883 samples collected in Northeastern USA using polymerase chain reaction determined that dianthicola P. parmentieri were found 38.1% 53.3% all samples, respectively, 20.6%...
Abstract Background Andrimid is reported to be a novel kind of polyketide-nonribosomal peptide hybrid product (PK-NRPs) that inhibits fatty acid biosynthesis in bacteria. Considering its great potential biomedicine and biofarming, intensive studies have been conducted increase the production andrimid overcome excessive costs chemosynthesis. In screening for species with broad-spectrum antibacterial activity, we detected fermentation products Erwinia persicina BST187. To production, BST187...
persicina is a gram-negative bacterium that causes diseases in plants. Recently, E. BST187 was shown to exhibit broad-spectrum antibacterial activity due its inhibitory effects on bacterial acetyl-CoA carboxylase, demonstrating promising potential as biological control agent. However, the lack of suitable genetic manipulation techniques limits exploitation and industrial application. Here, we developed an efficient transformation system for persicina. Using pET28a starting vector, expression...
Verticillium dahliae causes wilt, resulting in significant losses to potato production. Benzovindiflupyr, a succinate dehydrogenase inhibitor, effectively controls V. dahliae. However, frequent applications of the chemical may expedite development fungicide resistance pathogen population. To evaluate risk benzovindiflupyr resistance, 38 strains were obtained from diseased potatoes Maine. The sensitivity field population was determined based on effective concentration for 50% inhibition...

An outbreak of blackleg and soft rot potato, caused primarily by the bacterial pathogen Dickeya dianthicola, has resulted in significant economic losses northeastern United States since 2015. The spread this seedborne disease is highly associated with seed distribution; therefore, likely tubers. To describe epidemic track inoculum origins, a total 1,183 potato samples were collected from 11 states 2015 to 2019. Of these samples, 39.8% tested positive for D. dianthicola. Seventeen isolates...
Dickeya dianthicola has caused an outbreak of blackleg and soft rot potato in the eastern half United States since 2015. To investigate genetic diversity pathogen, a comparative analysis was conducted on genomes D. strains. Whole 16 strains from were assembled compared with previously sequenced isolated or carnation. Among 32 strains, eight distinct clades distinguished based phylogenomic analysis. The grouped into three clades, majority clade I. Clade I unique homogeneous, suggesting recent...
Pink rot (Phytophthora erythroseptica) of potato is a major concern in many production regions. The pathogen produces zoospores that serve as primary inoculum for infection. To understand how the pink incidence related to population, qualitative, and quantitative chemical analyses were conducted. It was demonstrated P. erythroseptica required minimal population 103 zoospores/ml (threshold) initiating germination subsequent infection; percentage zoosporic positively correlated with density...
High bicarbonate levels and low temperature may have an impact on microalgae cultivation. However, changes in cellular composition response to the combination of above stresses are still poorly understood. In this study, combined effects biochemical alkaliphilic Dunaliella salina HTBS were investigated. Comparing control condition 25°C without bicarbonate, cell density was increased from 0.69 1.18 treatment 0.15 M (16 °C) while lipid\protein\carbohydrate contents 34.71% 43.94%, 22.44%...
Dickeya dianthicola (Samson) is an important pathogen causing blackleg disease of potato. Previous work suggested that insects might vector species Pectobacteriaceae between plants but no conclusive has confirmed this. Green peach aphids (Myzus persicae Sulzer) and Colorado potato beetles (Leptinotarsa decemlineata Say) are aggressive pests related to known vectors several bacteria other than D. dianthicola. This study sought determine whether these for infection. Neither insect showed...
Light is very important for photosynthesis in plants. However, excess light can result photodamage to the photosynthetic apparatus. Via nonphotochemical quenching (NPQ), oxidative stress caused by energy be counteracted photoprotective mechanisms that evolve photosynthetic/oxygenic organisms. Energy-dependent (qE), as major NPQ component, relies on accumulation of specific proteins are termed light-harvesting complex stress-related (LHCSR) microalgae and mosses. LHCSRs have been reported...
