Aggressiveness Variation in Czech Isolates of Erysiphe cichoracearum Pathotype AB1B2CCm
Introduction. Erysiphe cichoracearum /Ec/ is the predominating powdery mildew species on cucurbits in the Czech Republic (5). Its occurrence and spreading on cucurbits can be influenced not only by virulence, but also by aggressiveness of isolates within natural pathogen populations. Both forms of pathogenicity have an impact on plant cultivation and protection and should be considered in resis...
متن کاملOverexpression of a New Chitinase Gene EuCHIT2 Enhances Resistance to Erysiphe cichoracearum DC. in Tobacco Plants
In this study, we cloned a new chitinase gene, EuCHIT2, from Eucommia ulmoides Oliver (E. ulmoides) using rapid amplification of cDNA ends (RACE) technology and constructed an overexpression vector, pSH-35S-EuCHIT2, to introduce it into tobacco (Nicotiana tabacum cv. Xanthi). Resistance to Erysiphe cichoracearum de Candolle (E.cichoracearum DC) and molecular mechanisms in the transgenic tobacco...
متن کاملSubcellular Distribution of Glutathione Precursors in Arabidopsis thaliana
Glutathione is an important antioxidant and has many important functions in plant development, growth and defense. Glutathione synthesis and degradation is highly compartment-specific and relies on the subcellular availability of its precursors, cysteine, glutamate, glycine and γ-glutamylcysteine especially in plastids and the cytosol which are considered as the main centers for glutathione syn...
متن کاملDifferential responses of G-protein Arabidopsis thaliana mutants to ozone
• Ground-level ozone (O 3 ) curtails agricultural production in many regions worldwide. However, the etiology of O 3 toxicity remains unclear. Activated oxygen species appear to inflict biochemical lesions and propagate defense responses that compound plant injury. Because some plant defense responses involve membranedelimited GTPases (G proteins), we evaluated the O 3 sensitivity of Arabidopsi...
متن کاملAcclimation responses of Arabidopsis thaliana to sustained phosphite treatments
Phosphite (H₂PO⁻₃) induces a range of physiological and developmental responses in plants by disturbing the homeostasis of the macronutrient phosphate. Because of its close structural resemblance to phosphate, phosphite impairs the sensing, membrane transport, and subcellular compartmentation of phosphate. In addition, phosphite induces plant defence responses by an as yet unknown mode of actio...
