Background: Plants develop sustainable defence responses to pathogen attacks through resistance (R) genes contributing to effector-triggered immunity (ETI). TIR-NB-LRR genes (TNL genes) constitute a major family of ETI R genes in dicots. The putative functions or roles of the TIR, NB and LRR domains of the proteins they encode (TNLs) are well...

Plants trigger appropriate defense responses, notably, through intracellular nucleotide-binding (NB) and leucine-rich repeat (LRR)-containing receptors (NLRs) that detect secreted pathogen effector proteins. In NLR resistance genes, the toll/interleukin-1 receptor (TIR)-NB-LRR proteins (TNLs) are an important subfamily, out of which...

Root-knot nematodes (RKN; Meloidogyne spp.) are predominant polyphagous pests of crops in the Central Valley of Chile. Twenty RKN populations from this region were collected from diverse crops and subsequently identified with both sequence-characterized amplified region and isoenzyme markers. Populations included three RKN species: Meloidogyne...

Advances in pyramiding resistance genes to root-knot nematodes in Prunus rootstocks. 9. International Peach symposiumHS

The ectoparasitic dagger nematodes Xiphinema index and Xiphinema diversicaudatum, often at low numbers in the soil, are vectors of grapevine nepoviruses, which cause huge agronomical problems for the vineyard industry. This study reports a method, based on real-time PCR, for the specific detection of these species and of the closely related...

The ectoparasitic dagger nematode, Xiphinema index, transmits Grapevine fanleaf virus (GFLV), which is responsible for a progressive degeneration of grapevines occurring across the world's vineyards. Since 2000, new data on the biology and ecology of the vector nematode and on the virus-nematode and plant-nematode interactions have contributed...
