Metabolic and transcriptomic responses of leaves from European potato reference cultivars with differential tolerance to long-term drought

ABSTRACT: Systems responses of mature leaves from 4 reference cultivars of a larger collection of European potato cultivars (Solanum tuberosum L.) are investigated by metabolome profiling and RNA-Sequencing. The chosen reference cultivars, Milva, Alegria, Desiree, and Saturna, vary in ascending order in regard to drought tolerance. Systems analyses are based on 3 independent field trials and 3 paralleled greenhouse trials. Robust responses across all cultivars and conditions to natural seasonal drought stress comprise proline, raffinose, galactinol, arabitol, arabinonic acid, chlorogenic acid, and 102 transcripts which consist to a high proportion of heat shock proteins and genes with signaling or regulatory functions, such as a homolog of abscisic acid receptor PYL4. Constitutive differences of the
