Association genetics, geography, and ecophysiology link stomatal patterning in Populus trichocarpa with carbon gain and disease resistance trade-offs

Popis výsledku v původním jazyce

Stomata are essential for diffusive entry of gases to support photosynthesis, but may also expose internal leaf tissues to pathogens. To uncover trade-offs in range-wide adaptation relating to stomatal traits, we investigated the underlying genetics of stomatal traits and linked variability in these traits with geoclimate, ecophysiology, condensed foliar tannins, and pathogen susceptibility in black cottonwood (Populus trichocarpa). Upper (adaxial) and lower (abaxial) leaf stomatal traits were measuredfrom 454 accessions collected throughout much of the species range. We calculated broad-sense heritability (H2) of stomatal traits and using SNP data from a 34K Populus SNP array, performed a genome-wide association (GWAS) to uncover genes underlying stomatal trait variation. H2 values for stomatal traits were moderate (average=0.33). GWAS identified genes associated primarily to adaxial stomata, including polarity genes (PHABULOSA), stomatal development genes (BRASSINOSTEROID-INSENSITIV
