Resistance in Lycopersicon esculentum Intraspecific Crosses to Race T1 Strains of Xanthomonas campestris pv. vesicatoria Causing Bacterial Spot of Tomato.
ABSTRACT We used molecular markers to identify quantitative trait loci (QTL) that confer resistance in the field to Xanthomonas campestris pv. vesicatoria race T1, a causal agent of bacterial spot of tomato. An F(2) population derived from a cross between Hawaii 7998 (H 7998) and an elite breeding line, Ohio 88119, was used for the initial identification of an association between molecular mark...
متن کاملfirst report of cladosporium sphaerospermum causing leaf spot disease of aloe vera in india
this paper deals with the study of a leaf spot disease observed on aloe vera leaves in various nurseries and botanical gardens during the routine surveys of two consecutive years of 2010 and 2011. the symptoms appeared in the form of circular to oval, brown to black, sunken spots on abaxial surface of leaves. the disease was observed only in january to february during the survey. colonieson pda...
متن کاملBiological role of xanthomonadin pigments in Xanthomonas campestris pv. campestris.
Previous studies have indicated that the yellow pigments (xanthomonadins) produced by phytopathogenic Xanthomonas bacteria are unimportant during pathogenesis but may be important for protection against photobiological damage. We used a Xanthomonas campestris pv. campestris parent strain, single-site transposon insertion mutant strains, and chromosomally restored mutant strains to define the bi...
متن کاملGenome Sequence of Xanthomonas campestris pv. campestris Strain Xca5
An annotated high-quality draft genome sequence for Xanthomonas campestris pv. campestris race 1 strain Xca5 (originally described as X. campestris pv. armoraciae), the causal agent of black rot on Brassicaceae plants, has been determined. This genome sequence is a valuable resource for comparative genomics within the campestris pathovar.
متن کاملDevelopment of a Model to Predict the Primary Infection Date of Bacterial Spot (Xanthomonas campestris pv. vesicatoria) on Hot Pepper
A population model of bacterial spot caused by Xanthomonas campestris pv. vesicatoria on hot pepper was developed to predict the primary disease infection date. The model estimated the pathogen population on the surface and within the leaf of the host based on the wetness period and temperature. For successful infection, at least 5,000 cells/ml of the bacterial population were required. Also, w...
