Data from: Genome-wide exon-capture approach identifies genetic variants of Norway spruce genes associated with susceptibility to Heterobasidion parviporum infection

Root and butt rot caused by members of the Heterobasidion annosum species
complex is the most economically important disease of conifer trees in
boreal forests. Wood decay in the infected trees dramatically decreases
their value and causes considerable losses to forest owners. Trees vary in
their susceptibility to Heterobasidion infection, but the genetic
determinants underlying the variation in the susceptibility are not
well-understood. We performed the identification of Norway spruce genes
associated with the resistance to Heterobasidion parviporum infection
using genome-wide exon-capture approach. Sixty-four clonal Norway spruce
lines were phenotyped, and their responses to H. parviporum inoculation
were determined by lesion length measurements. Afterwards, the spruce
lines were genotyped by targeted resequencing and identification of
genetic variants (SNPs). Genome-wide association analysis identified 10
SNPs located within 8 genes as significantly associated with the larger
necrotic lesions in response to H. parviporum inoculation. The genetic
variants identified in our analysis are potential marker candidates for
future screening programs aiming at the differentiation of
disease-susceptible and resistant trees.
