|a Polygalacturonase (PG), which digests the pectin of plant cell walls, contributes to pathogenicity of fungi in plants. To explore the role of PG in pathogenicity of the fungal cotton pathogens Verticillium dahliae and Fusarium oxysporum f. sp. vasinfectum, VDPG1 and FOVPG1 were cloned and their expression in different cotton (Gossypium hirsutum) cultivars and media was analyzed. VDPG1 and FOVPG1 were strongly upregulated during infection. Purified VDPG1 and FOVPG1 play important roles in the symptom development of both resistant and susceptible cotton. Moreover, after inoculation with purified PGs, the hydroxyproline content of the cell walls increased in cotton seedlings, with resistant cultivar seedlings showing significantly higher hydroxyproline content than seedlings of the susceptible cultivar. PG gene expression analysis in different media showed that both PG genes were induced in pectin medium but not in glucose medium. This study highlighted the role of VDPG1 and FOVPG1 in pathogenicity and virulence, which were detected in fungus-inoculated cotton, suggesting that PGs play an important role in the pathogenicity of V. dahliae and F. oxysporum f. sp. vasinfectum
