Background The history of the world citrus industry is marked by a series of diseases caused by different etiologic agents. Several of them are characterized as biotrophic pathogens like Xanthomonas citri subsp. citri, three Candidatus Liberibacter spp and Citrus leprosis virus C (CiLV-C). In plant-pathogen interactions, the role of salicylic acid (SA) in activating defense related genes is wel...

CP-99,219 is a trifluoronaphthyridone with significant antibacterial activity that includes the family Enterobacteriaceae (MICs for 90% of the strains tested [MIC90s], < or = 0.015 to 0.5 micrograms/ml), Moraxella catarrhalis, Haemophilus influenzae, and gonococci (MICs, < or = 0.015 micrograms/ml). Legionella spp. were also CP-99,219 susceptible, with MICs of 0.008 to 0.12 micrograms/ml. CP-99...

Secondary metabolite-based chemotaxonomic classification of Streptomyces (8 species, 14 strains) was performed using ultraperformance liquid chromatography-quadrupole-time-offlight- mass spectrometry with multivariate statistical analysis. Most strains were generally well separated by grouping under each species. In particular, S. rimosus was discriminated from t he r emaining s ev en s pecies ...

Transcription activator like effectors (TALEs) are injected via the type III secretion pathway of many plant pathogenic Xanthomonas spp. into plant cells where they contribute to disease or trigger resistance by binding to DNA and turning on TALE-specific host genes. Advances in our understanding of TALEs and their targets have yielded new models for pathogen recognition and defense. Similarly,...

India is one of the leading citrus−producing countries, next to China and Brazil. Despite sizeable production, especially lemons limes, contributes meagerly world’s citrus market. Of various factors responsible for restricted quantum export, canker (Xanthomonas citri pv. citri) serious causes directly impacts appearance fruits. Considering extent damage, present study aimed understand impact Xa...

Here, we report the draft genome sequence of Xanthomonas campestris LMG 8031, for which nearly no genetic information is available, despite its good xanthan-producing properties. We performed an Illumina-based sequencing approach of LMG 8031. The genome revealed a 5.0-Mb chromosome having 4,434 coding sequences and a G+C content of 65%.

Citrus canker is a citrus disease species that created by the bacterium Xanthomonas citri subsp.citri. Many citrus, such as oranges, lime, and grapefruit are affected by the infectious bacteria and stems, leaves and fruits are experiencing loss. In this experiment antibacterial effects of five kinds of antibiotics including ampicillin, kanamycin, chloramphenicol, penicillin, streptomycin, Crono...
