Physiological and dynamic transcriptome analysis of two potato varieties reveal response of lignin and MAPK signal to dry rot caused by Fusarium sulphureum

Investigations on effect of dry root (F. solani var. coeruleum and F. sulphureum) 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 Fusarium in relation to intact tubers was found. Moreover increase of reducting saccharides and bisaccharides in potatoes infected by Fusarium compared with controls was observed. Level of vit. C was decreased in tubers affected by Fusarium in all potato cultivars. In this experiment changes in chemical composition content in potato tubers were connected with a kind of dry rot patogen.

Susceptibility And Resistance

The tuber nematode Ditylenchus destructor is the causative agent of ditylenchiasis, or dry rot of potatoes, and causes significant damage to the crop both during the growing season and during storage. Methods for evaluating potato varieties for resistance to tuberous nematode in laboratory conditions have been developed to reduce the search term for a source or donor of nematode resistance. Methods for obtaining a suspension of a tuber nematode, methods of inoculation of tubers, a method for assessing potato varieties for susceptibility and resistance to the tuberous nematode Ditylenchus destructor are presented. Infection of tubers is carried out by introducing a suspension of nematodes into the wounds inflicted on the potato tubers. 6 methods were tested. The best infection and reproduction of nematodes occurred when nematodes were introduced into the “lattice”, “holes”, “pyramids”. Depending on the value of the average score of the lesion by ditylenchiasis and reproduction by the tuber nematode, the varieties are divided into 5 groups: highly resistant (average score 0), resistant (0.1–1), moderately resistant (1.1–3), susceptible (3.1–4), highly susceptible (4.1–5).

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.
