Project description:Gene expression profiling of upland cotton line Im216 to inoculation with Xanthomonas campestris pv. malvacearum race 1. Fifth or sixth leaves of the bacterial blight-resistant cotton line Im216, which had been grown in a plant growth chamber, were infiltrated with a suspension of about 5x10^6 colony-forming units ml^-1 of Xanthomonas campestris pv. malvacearum race 1 in sterile saturated CaCO3 solution or were not inoculated (control). Keywords: Time-course
Project description:We performed a transcriptomic analysis of the necrotrophic bacteria Xanthomonas campestris pv. campestris exposed to two different isothiocyanates (allyl-isothiocyanate and indol-3-carbinol), searching for mechanisms of adaptation and detoxification of these chemicals.
Project description:Black rot, caused by Xanthomonas campestris pv. campestris (Xcc) is one of the most devastating diseases of cruciferous crops worldwide. The pathogen infects and multiplies in plant vascular tissues and, as the disease progresses, the veins of infected tissues turn black and characteristic V-shaped lesions appear along the margins of leaves.The aim of this work is to identify differentially expressed genes from Brassica oleracea during early infection by Xcc, in an attempt to identify proteins related to resistance. Cabbge seedlings were inoculated with Xanthomonas campestris pv campestris (Xcc) suspension and cabbage gene expression at 6h., 24h. And 48h. After inoculation was assessed with help of Brassica 95k EST microarray chip.
Project description:Purpose -Comparison of proteome incubated in different media (rich and minimal media) -Three Xanthomonas species were used (Xanthomonas oryzae pv. oryaze, X. campestris pv. vesicatoria, and X. axonopodis pv. glycines. -Shotgun proteomic was used
Project description:Xylem sap of young cabbage plantlets was recovered from root pressure exudation and used as a growth medium for the vascular pathogen Xanthomonas campestris pv campestris, the causative agent of the black rot of Brassicaceae.
Project description:Plant pathogenic bacteria disseminate and survive through transmission to and by seeds of hosts and non-hosts plants. To investigate the interaction between xanthomonads and developing seeds of Medicago truncatula, plants at the flower bud stage were spray inoculated until runoff with xanthomonads suspensions. Using the Medicago NimbleGen chip, a transcriptomic analysis was performed on seeds to characterize the molecular dialogue between Xanthomonas campestris pv. campestris in an incompatible situation with M. truncatula seeds and Xanthomonas alfalfae pv. alfalfae in a compatible situation at two developmental time points (16 and 32 days atfter pollination (DAP).
Project description:Brassica nigra plants, a Brassicaceae close to Arabidopsis thaliana, was used for combined stresses experiments. In this study, we performed a whole-genome microarray analysis on five-week-old plants and compared untreated plants and plants treated different single or dual stresses: the larvae Pieris brassicae, egg extract of Pieris brassicae, the bacterial Xanthomonas campestris pv. raphani, the aphid Brevicoryne brassicae or by combined stresses eggs of P. brassicae / P. brassicae, X. campestris / P. brassicae, B. brassicae / P. brassicae.
Project description:Plant pathogenic bacteria disseminate and survive through transmission to and by seeds of hosts and non-hosts plants. To investigate the interaction between xanthomonads and developing seeds of Medicago truncatula, plants at the M-oM-,M-^Bower bud stage were spray inoculated until runoff with xanthomonads suspensions. Using the Medicago NimbleGen chip, a transcriptomic analysis was performed on seeds to characterize the molecular dialogue between Xanthomonas campestris pv. campestris in an incompatible situation with M. truncatula seeds and Xanthomonas alfalfae pv. alfalfae in a compatible situation at two developmental time points (16 and 32 days atfter pollination (DAP). Six-condition experiment, 16dap_Mock versus 16dap_Xaa, 16dap_Mock versus 16dap_Xcc, 32dap_Mock versus 32dap_Xaa, 32dap_Mock versus 32dap_Xcc. Biological replicates: 6 controls (16dap_Mock, 32dap_Mock), 12 treatments (16dap_Xaa, 16dap_Xcc, 32dap_Xaa, 32dap_Xcc), independently grown and harvested. One replicate per array.
