List of silver birch and hybrid aspen stress response genes used in the study.

Primer sequences are provided alongside the corresponding gene ID from TAIR, CoGe, PlantGenIE databases. Amplification factor was calculated based on 10-fold template DNA dilution series ranging from 100ag to 1ng and displayed for all genes used in Fig 1. Genes that did not display a specific single band in the electrophoresis and did not produce consistent melting curves (S3 Fig), the amplification factor was not calculated. (XLSX)
