In Sweden’s Norway spruce (Picea abies), genome-wide coding variants show latitudinal clines in defence and flowering genes, with steepest missense SNP shifts in RPL18C and LAF3.
- Why it matters: Local adaptation in plants is shaped by environmental cues, but it is unclear how defence and reproductive pathways vary across latitude when population structure is weak.
- What they did: Using an exome capture dataset, the study tested coding-region missense SNP allele frequencies across a latitudinal gradient and identified clines in RPL18C, LAF3, ZDP, and flowering genes including BAM1, VRN1, FCA, and TFL1.
- The result: The observed clines in these loci provide evidence for local adaptation across Swedish Norway spruce populations and suggest these variants may underlie differential defence and flowering under local climate and light conditions.
