“…Santala et al . () considered that seed potatoes had been the main source of infestation in the island of Lolland in Denmark after large‐scale potato production started there in 2000. Introductions may occur either through seed tubers carrying viruliferous spore balls of S. subterranea which are deposited in soil after planting or by a soil population of S. subterranea acquiring the virus from infected plants, as demonstrated by Arif et al .…”

The importance of the infected seed tuber and soil inoculum in transmitting Potato mop‐top virus to potato plants

Potato mop‐top virus (PMTV), the cause of spraing in potato tubers, is transmitted by Spongospora subterranea, the cause of powdery scab, and by planting infected seed tubers. This study was undertaken to determine the relative importance of these sources of infection in seed potato production in Scotland. The transmission of PMTV from tested seed tubers to daughter plants was examined over 2 years and six cultivars. The development of foliar symptoms varied with year and cultivar. Infection of daughter tubers derived from PMTV‐infected seed tubers was more prevalent on plants affected by foliar symptoms than those without symptoms. The rate of transmission of PMTV from infected seed tubers to daughter tubers ranged from 18 to 54%. Transmission was affected by cultivar and by origin of seed tubers used for a cultivar, but not by a cultivar's sensitivity to PMTV infection. The incidence of PMTV in daughter tubers of cv. Cara grown from seed potatoes from one source (common origin) by more than 25 seed producers was examined over two successive generations. The incidence of PMTV in daughter tubers was not correlated with that in the seed tubers but appeared to be strongly associated with soil inoculum. The incidence of PMTV was correlated with powdery scab in those crops in which both were present. There was some evidence from soil tests conducted in 2006 using a tomato bait plant and real‐time RT‐PCR that planting PMTV‐infected seed potatoes could increase the risk of introducing the virus into land not infested by PMTV.

“…Potato mop-top virus (PMTV) and Beet necrotic yellow vein virus (BNYVV) are transmitted by the plasmodiophorids Spongospora subterranea and Polymyxa betae, respectively. Both of them have recently been introduced into Sweden and are now spreading (Rydén et al 1986;Sandgren 1995;Lennefors et al 2000;Santala et al 2010). The most important factor for this spread is probably the movement of infected plant material and soil, but climate factors may also have been involved.…”

The impact of global warming on plant diseases and insect vectors in Sweden

Cold winters and geographic isolation have hitherto protected the Nordic countries from many plant pathogens and insect pests, leading to a comparatively low input of pesticides. The changing climate is projected to lead to a greater rise in temperature in this region, compared to the global mean. In Scandinavia, a milder and more humid climate implies extended growing seasons and possibilities to introduce new crops, but also opportunities for crop pests and pathogens to thrive in the absence of long cold periods. Increased temperatures, changed precipitation patterns and new cultivation practices may lead to a dramatic change in crop health. Examples of diseases and insect pest problems predicted to increase in incidence and severity due to global warming are discussed.

“…Compared with many other potato-infecting viruses, the genetic diversity of PMTV is low. Recent surveys have revealed a wide distribution of PMTV in the Nordic countries and the USA [2,5,11,22,27] and have made a large number of new isolates available. The aim of this study was to characterize PMTV sequences from Sweden, Denmark and the USA and to use them with sequences available from previous studies to analyse the genetic diversity and evolution of PMTV.…”

Diversity and evolution of potato mop-top virus

et al. 2015

Nearly complete sequences of RNA-CP and 3'-proximal RNA-TGB were determined for 43 samples of potato mop-top virus (PMTV) originating from potato tubers and field soil from Sweden, Denmark and the USA. The results showed limited diversity and no strict geographical grouping, suggesting only a few original introductions of PMTV from the Andes. Two distinguishable types of RNA-CP and RNA-TGB were found in the samples, but no specific combination of them correlated with spraing symptoms in tubers. Lack of positive selection in the coding sequences indicates that there is no specific molecular adaptation of PMTV to new vectors or hosts.
