Resistance of Xanthomonas euvesicatoria strains from Brazilian pepper to copper and zinc sulfates.
Bacterial spot, caused by Xanthomonas spp., is one of the major bacterial diseases in pepper (Capsicum annuum L.). The infection results in reduced crop yield, particularly during periods of high rainfall and temperature, due to the low efficiency of chemical control with copper bactericides. This study evaluated the copper and zinc sulfate sensitivity of 59 pathogenic strains of Xanthomonas eu...
متن کاملInduced resistance against the Asian citrus psyllid, Diaphorina citri, by β-aminobutyric acid in citrus.
β-Aminobutyric acid (BABA) is known to induce resistance to microbial pathogens, nematodes and insects in several host plant/pest systems. The present study was undertaken to determine whether a similar effect of BABA occurred against the Asian citrus psyllid, Diaphorina citri Kuwayama, in citrus. A 25 mM drench application of BABA significantly reduced the number of eggs/plant as compared with...
متن کاملPCR-based assay for the detection of Xanthomonas euvesicatoria causing pepper and tomato bacterial spot.
AIMS To develop a PCR-based assay for Xanthomonas euvesicatoria detection in culture and in planta. METHODS AND RESULTS A fragment of 1600 bp specific for X. euvesicatoria was found by repetitive extragenic palindromic sequence-PCR. Among the primers designed on the basis of the partially sequenced fragment, the primers Xeu2.4 and Xeu2.5 direct amplification of the expected product (208 bp) f...
متن کاملSub-species diversity of Xanthomonas euvesicatoria Bulgarian and Macedonian strains from pepper
Sub-species diversity of pepper populations of Xanthomonas euvesicatoria in Bulgaria and Macedonia in 2012 was the object of this study. Species determination of 44 strains was performed by molecular methods using two pairs of species-specific primers and RFLP (restriction fragment length polymorphism) analysis of the 16S-23S ITS region with HpaII. The populations were characterized by genotypi...
متن کاملDL-β-Aminobutyric Acid-Induced Resistance in Soybean against Aphis glycines Matsumura (Hemiptera: Aphididae)
Priming can improve plant innate capability to deal with the stresses caused by both biotic and abiotic factors. In this study, the effect of DL-β-amino-n-butyric acid (BABA) against Aphis glycines Matsumura, the soybean aphid (SA) was evaluated. We found that 25 mM BABA as a root drench had minimal adverse impact on plant growth and also efficiently protected soybean from SA infestation. In bo...
