Abstract

• To assess the effect of different concentrations of gossypol (0, 2, 4, 10 and 20mgl-1) in combination with NaCl and Na2SO4 (20mScm-1) on the conidial germination and viability of Fusarium oxysporum f.sp. vasinfectum (Fov). A multinomial logistic model was developed to estimate the germination probability of Fov. The inhibitory effect was markedly evident at the two highest concentrations of gossypol; it varied among the isolates tested and with time, and it was attenuated by the presence of sodium salts. The inhibition was temporary as the germination probability increased after 8?h. Fluorescent staining revealed that gossypol either killed the conidia or retarded the elongation of the germ tubes. Fov showed the ability to overcome gossypol inhibition over time, and the inhibitory effect is reduced under saline conditions. Differential responses among Fov isolates to the presence of gossypol suggest that gossypol tolerance is genetically determined in the pathogen. This study suggests that selecting for high plant gossypol cultivars would have minimal effect on the overall Fov resistance of cotton. A new statistical model was developed to explore the statistical significance of plant-pathogen interactions. (literal)
