Plants respond to pathogens either by investing more resources into immunity which is costly to development, or by accelerating reproductive processes such as flowering time to ensure reproduction occurs before the plant succumbs to disease. In this study we explored the link between flowering time and pathogen defense using the interaction between Arabidopsis thaliana and the root infecting fu...
Physiological race determination of 143 Fusarium oxysporum f. sp. lycopersici (FOL) isolates collected along 30 years in major tomato‐producing regions Brazil. races were determined via root‐dipping inoculation differential tomato accessions and by the PCR‐based marker system Hirano Arie (2006). According to pathogenicity/virulence assays, five 1, 23 2 115 3 identified. FOL 1 prevailed up early...
بیماری پژمردگی فوزاریومی گوجه فرنگی که عامل آن قارچ fusarium oxysporum f. sp. lycopersici است، یکی از مهمترین بیماریهای خاکزاد این گیاه است . تعداد 150 استرین باکتری از خاک های گردآوری شده از مناطق مختلف ایران به روش تهیه سری رقت (serial dilution) روی محیط کشت hicrome bacillus agar جدا شد. در ارزیابی توان بازدارندگی استرین های باکتریایی به روش کشت متقابل با قارچ بیماری زا، تعداد هشت استرین توان...
This work was aim to evaluate the pathogenicity and level of aggressiveness ten strains Fusarium oxysporum f. sp. elaeidis (Foe) on palm oil seedlings susceptible vascular wilt. For this purpose, radial growth, sporulation morphological characteristics Foe from farm Cameroon Development Corporation (South-west) were studied in vitro. In addition, 500 wilt aged 5 months distributed a randomized ...
The rhizosphere microbial community in a hydroponics system with multiple parallel mineralization (MPM) can potentially suppress root-borne diseases. This study focused on revealing the biological nature of the suppression against Fusarium wilt disease, which is caused by the fungus Fusarium oxysporum, and describing the factors that may influence the fungal pathogen in the MPM system. We demon...
ABSTRACT Development of 108 epidemics of Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceris were studied on cvs. P-2245 and PV-61 in field microplots artificially infested with races 0 and 5 of F. oxysporum f. sp. ciceris in 1986 to 1989. Disease progression data were fitted to the Richards model using nonlinear regression. The shape parameter was influenced primarily by date...
