Genomics of resistance in Norway spruce to Heterobasidion annosum s.s.and Heterobasidion parviporum

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.

FIGURE 3. Chronogram and estimated divergence times of Heterobasidion spp. generated from molecular clock analysis using the RPB1-RPB2 data. Chronogram obtained using the Heterobasidion divergence time of 19.72 Mya (Chen et al. 2015) as the calibration point is shown. The calibration point and objects of this study are marked in the chronogram. The geological time scale is in millions of years ago (Mya). Divergence times of H. amyloideopsis highlighted in bold.
