Identification of potato varieties suitable for cold storage and reconditioning: A safer alternative to anti-sprouting chemicals for potato sprouting control.

Low temperature storage as an alternative to anti-sprouting chemicals in potato storage may induce reducing sugars (RS) accumulation (i.e. glucose and fructose) in potato tubers.

Increase of Glycoalkaloid Content in Potato Tubers by Greening as a Method to Reduce the Spread of and spp. in Seed Production Systems.

and species are the causal agents of blackleg and soft rot diseases. This article explores the possibility of using the glycoalkaloids (GAs) naturally produced by the potato tuber after the greening process as a blackleg control method. We first tested the effect of GAs extracted from four potato cultivars on the growth and viability of one and one strain in growth media.

Pathogenicity and Relative Abundance of and Species in Switzerland: An Epidemiological Dichotomy.

and species are the causal agents of blackleg and soft rot diseases in potatoes. The main pathogenic species identified so far on potatoes are , , , , , and . Ten years ago, the most prevalent Soft Rot Pectobacteriaceae in Europe were the species, and , with some variations among countries.

Large-Scale RT-qPCR Diagnostics for Seed Potato Certification.

Unlabelled: Every year, Agroscope examines nearly 300,000 tubers for the presence of viruses, as regulated for the certification of seed potatoes intended for Swiss growers. Since 2016, this examination has been performed via RT-qPCR on dormant tubers directly after harvest. This method offers fast results and eliminates the need for the use of Rindite, which is a toxic and polluting gaseous compound previously used in Switzerland to break the dormancy of seed tubers.

Incomplete Infection of Secondarily Infected Potato Plants - an Environment Dependent Underestimated Mechanism in Plant Virology.

The common assumption in potato virus epidemiology is that all daughter tubers produced by plants coming from infected mother tubers (secondary infection) will become infected via systemic translocation of the virus during growth. We hypothesize that depending on the prevalent environmental conditions, only a portion of the daughter tubers of a plant that is secondarily infected by viruses may become infected. To test this hypothesis experimental data from standardized field experiments were produced in three contrasting environments at 112, 3280, and 4000 m a.

Changes in oxylipin synthesis after Phytophthora infestans infection of potato leaves do not correlate with resistance.

Oxylipins constitute a class of molecules notably involved in host-pathogen interactions. In the potato-Phytophthora infestans (Mont.) De Barry (P.
