Investigations on effect of dry root (<i>F. solani</i> var. <i>coeruleum</i> and <i>F. sulphureum</i>) pathogens on three potato cultivares Azalia, Pola, Odra chemical composition were carried out. Content of total nitrogen and protein, total saccharides, reducting and bisaccharides and vit. C was investigated. Significant decrease of total and protein nitrogen content in potatoes affected by <i>Fusarium</i> in relation to intact tubers was found. Moreover increase of reducting saccharides and bisaccharides in potatoes infected by <i>Fusarium</i> compared with controls was observed. Level of vit. C was decreased in tubers affected by <i>Fusarium</i> in all potato cultivars. In this experiment changes in chemical composition content in potato tubers were connected with a kind of dry rot patogen.

Abstract A description is provided for Fusarium sulphureum[Gibberella cyanogena]. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Solanum tuberosum; also isolated from the following hosts: Arachis, Citrus, Cocos, Cupressus, Elasis, Fragaria, Gleditsia, Hibiscus, various Leguminosae, Lycopersicon, Linus, Phaseolus, Picea, Pinus, Pisum, Solanum, Sorghum, Trifolium, Triticum, Zea and also from animal and poultry feed and from soil. DISEASE: Fusarium sulphureum[Gibberella cyanogena] is often reported under the name Fusarium sambucinum[Gibberella pulicaris] f. 6; economically it is most important as the cause of potato tuber dry rot (54, 536; 56, 3195). GEOGRAPHICAL DISTRIBUTION: Probably world wide. It has been reported on potato tubers from Australia, Canada, Cyprus, East and West Germany, Iran, New Zealand, UK and USA. TRANSMISSION: By soil, water and planting material.

Fusarium oxysporum is the most important pathogen of potatoes which causes post-harvest destructive losses and deteriorates the market value of potato tubers worldwide. Here, F. oxysporum was used as a host pathogen model system and it was revealed that autophagy plays a vital role as a regulator in the morphology, cellular growth, development, as well as the pathogenicity of F. oxysporum. Previous studies based upon identification of the gene responsible for encoding the autophagy pathway components from F. oxysporum have shown putative orthologs of 16 core autophagy related-ATG genes of yeast in the genome database which were autophagy-related and comprised of ubiquitin-like protein atg3. This study elucidates the molecular mechanism of the autophagy-related gene Foatg3 in F. oxysporum. A deletion (∆) mutants of F. oxysporum (Foatg3∆) was generated to evaluate nuclear dynamics. As compared to wild type and Foatg3 overexpression (OE) strains, Foatg3∆ strains failed to show positive MDC (monodansylcadaverine) staining which revealed that Foatg3 is compulsory for autophagy in F. oxysporum. A significant reduction in conidiation and hyphal growth was shown by the Foatg3∆ strains resulting in loss of virulence on potato tubers. The hyphae of Foatg3∆ mutants contained two or more nuclei within one hyphal compartment while wild type hyphae were composed of uninucleate hyphal compartments. Our findings reveal that the vital significance of Foatg3 as a key target in controlling the dry rot disease in root crops and potato tubers at the postharvest stage has immense potential of disease control and yield enhancement.
