Comparative transcriptome analysis of genes related to tuberization in late and early maturing potato (Solanum tuberosum) cultivars.

ABSTRACT: Potato maturity is a complex and vital agronomic trait directly impacting yield, quality, and economic value. Despite its importance, the molecular regulatory networks governing potato maturity remain largely unexplored. In this study, the factors underlying maturity differences between early-maturing (KX23) and late-maturing (DN310) tetraploid potato cultivars were investigated for the first time under field conditions. Tuber yields, starch content, flowering time, maturity and the number of morphologically modified stolons and initiated tubers were measured, revealing that maturity differences between KX23 and DN310 are linked to the timing of tuberization processes. To explore the molecular basis of these differences, RNA-seq analysis was performed on hooked stolons, swollen stolons, an
