Lysobacter antibioticus 13-6, isolated from the roots of Chinese cabbage, effectively controls the pathogens Plasmodiophora brassicae, Xanthomonas oryzae pv. oryzicola, X. oryzae pv. oryzae, Xanthomonas axonopodis pv. dieffenbachiae, and Pseudomonas syringae pv. tabaci. We report the first draft genome sequence of the L. antibioticus species in China.

Flight direction is a major component of an animal's migratory success. However, few studies have focused on variation in flight direction both between and within individuals, which is likely to be correlated with other traits implied in migration processes. We report patterns of intra- and inter-individual variation in flight direction in the large white butterfly Pieris brassicae. The presenc...

The cultivation of cruciferous crops is threatened by extensive yield losses caused the soil-borne pathogen Plasmodiophora brassicae Woronin, 1877. objective study was to assess potential bacterial product BactoMix 5 for control clubroot on a naturally infested soil in growth chamber trials using P. brassicae-specific qPCR methodology. results did not show significant decrease nor reduction dis...

Plants release volatiles induced by herbivore feeding that may affect the diversity and composition of plant-associated arthropod communities. However, the specificity and role of plant volatiles induced during the early phase of attack, i.e. egg deposition by herbivorous insects, and their consequences on insects of different trophic levels remain poorly explored. In olfactometer and wind tunn...

Plasmodiophora brassicae causes clubroot, a major disease of Brassica oil and vegetable crops worldwide. P. brassicae is a Plasmodiophorid, obligate biotrophic protist in the eukaryotic kingdom of Rhizaria. Here we present the 25.5 Mb genome draft of P. brassicae, developmental stage-specific transcriptomes and a transcriptome of Spongospora subterranea, the Plasmodiophorid causing powdery scab...

Mitogen-activated protein kinase (MAPK or MPK) cascades play key roles in responses to various biotic stresses, as well as in plant growth and development. However, the responses of MPK and MPK kinase (MKK) in Chinese cabbage (Brassica rapa ssp. pekinensis) to Plasmodiophora brassicae, a causal agent of clubroot disease in Brassica crops, are still not clear. In the present study, a total of 11...

The hypertrophy and hyperplasia of infected roots into clubs are the intrinsic characteristics of clubroot, one of the economically most important diseases in Brassica crops worldwide. Polyamines, arginine (Arg)-derived metabolites, have long been recognized as cell proliferation and differentiation regulators in plants and consequently are suitable candidates for potential gall development fac...
