“…Temperature is well known to affect symptom expression and viral movement in pathosystems such as Cucumber green mottle mosaic virus (CGMMV) on cucumber (Moreno et al 2004) and melon (Sugiyama et al 2006), Cucumber mosaic virus (CMV) on melon (Takada 1979), Melon necrotic spot virus (MNSV) on melon (Kido et al 2008;Mallor et al 2003), and Tomato spotted wilt virus (TSWV), a member of the genus Tospovirus, on Capsicum chinense (Soler et al 1998) and peanut (Arachis hypogaea) (Mandal et al 2002). Because cucumber is cultivated at various temperatures for year-round production in Japan, we need to confirm whether resistance to MYSV on cucumber accessions is affected by temperature.…”

Melon yellow spot virus (MYSV), a member of the genus Tospovirus, is a devastating thrips-transmitted virus of cucurbits in Japan. Recently, we reported that cucumber accessions originating from South Asia, in particular Southeast Asia, had moderate resistance to MYSV. Here, we investigated the effect of three temperatures (20°C, 25°C, and 30°C) on symptom expression and viral spread of MYSV in plants of resistant cucumber accessions. No systemic infection developed in resistant cucumber plants after inoculation with melon isolate MYSV-S at low temperature (20°C); viral spread of MYSV-S and cucumber isolate MYSV-FuCu05P in inoculated cotyledons was suppressed. In contrast, higher incubation temperatures (25°C and 30°C) facilitated viral spread in inoculated cotyledons and systemic infection of MYSV-S. These data suggest that the resistance to MYSV of resistant cucumber accessions is temperature dependent.

“…En el experimento 2, se observó una mayor mortalidad en el tratamiento con el portainjertos de "Robusta", así como un incremento en la severidad de los síntomas del MNSV, con respecto al Experimento 1. Kido et al (2008) indican que los síntomas del MNSV aumentan cuando la temperatura es inferior a 20 °C, y la propagación viral y diseminación incrementan a temperaturas superiores a 25 °C.…”

ResumenMéxico es uno de los principales productores de sandía a nivel mundial. Pero la presencia de patógenos del suelo como nematodos, Fusarium oxysporum f. sp. niveum y el virus de la mancha necrótica del melón (MNSV) representan un serio problema para los productores. El uso de plantas injertadas es una buena alternativa para hacer frente a estos problemas, ayudando a incrementar el rendimiento y calidad en sandía. Los portainjertos de sandía silvestre (Citrullus lanatus var. citroides) han demostrado ser eficaces para el control de la mayoría de las enfermedades que se transmiten a través del suelo, además de tener alta resistencia a nematodos; no obstante, no se tiene registro sobre su resistencia al MNSV. Se realizaron dos experimentos para evaluar la resistencia al MNSV de portainjertos para sandía. En el experimento 1 se evaluaron los portainjertos de híbridos interespecíficos "RS-841" "Ercole" (Cucurbita maxima×Cucurbita moschata) y de sandía silvestre los portainjertos "Robusta", "RS0272" y "RS1833". En el experimento 2 se evaluaron los portainjertos "RS-841", "Ercole" y "Robusta". En ambos casos en suelos infestados con MNSV. Los portainjertos de sandía silvestre fueron altamente susceptibles al MNSV, en cambio los híbridos interespecíficos mostraron resistencia a esta enfermedad. El portainjertos "RS-841" fue el que produjo los frutos de mejor calidad. El rendimiento fue inferior con diferencia significativa cuando se utilizaron los portainjertos de sandía silvestre.

Thus, if tests for resistance are carried out under conditions that significantly differ from those that prevail in commercial fields, resistance assessments may be of little relevance.…”

Plant viruses are important agricultural pathogens, and are responsible for a significant number of commercially relevant plant diseases. There are very few efficient control measures for viral diseases, but the use of genetic resistance appears to be the most promising strategy, often conferring effective protection without additional costs or labour during the growing season, and without damaging the environment. Sources of virus resistance have been identified for most crop species, and many resistant cultivars are already commercially available and of widespread cultivation; however, much remains to be learned about genetic resistance. This review article considers three main aspects that require intense investigation. First, we review the identification of sources of resistance and how plant breeders and pathologists have focused on aspects of the breeding process particularly relevant to viruses, such as germplasm screening and the dissection of resistance phenotypes. Second, we review how molecular mechanisms controlling resistance have been unravelled, looking at case studies where resistance mechanisms are now understood in detail for each stage of the infection cycle. Third, we turn to the durability of resistance in a global context, examining factors that influence durability and how this can be predicted. We conclude with a short discussion of the technological and scientific opportunities provided by recent advances in the field.
