====== Strawberry (//Fragaria vesca//, //F. ananassa//) ====== Author: [[https://www.researchgate.net/profile/Inga_Morocko-Bicevska2|Inga Moročko-Bičevska]] ([[https://www.researchgate.net/profile/Joel_Pothier2|Joël F.

Introgression of the trait into commercial quality perennial-type germplasm was initiated by Roach //et al.// (2016). Resistance detected in two wild accessions US4808 and US4809 was found to be highly heritable and controlled by a major locus //FaRXf1// on linkage group 6D (Roach //et al.//, 2016). Annotation of the //FaRXf1// region in //F. vesca// genome revealed the presence of several resistance-associated genes, including nucleotide-binding leucine-rich
repeat (NB-LRRs), zinc finger and serine/threonine-protein
kinase genes (Roach //et al.//, 2016). Allelic diversity at the //FaRXf1// locus is unknown. ---- ===== Pathogen: //Xanthomonas arboricola// pv. //fragariae// ===== ==== Resistance gene: **none** ==== === Synonyms === //NA// === Source === //NA// === Status (identified, mapped, cloned, sequenced) === //NA// === Molecular markers === //NA// === Brief description === //NA// ---- ===== References ===== Hartung JS, Gouin CC, Lewers KS, Maas JL, Hokanson S (2003).
