Abstract

Recent advances have defined some of the components of photoperiodic
signalling that lead to tuberization in potato including orthologues of FLOWERING LOCUS T (StSP6A) and CYCLING DOF FACTOR (StCDF1). The aim of the current study is to investigate the molecular basis of permissive tuber initiation under long days in Solanum tuberosum Neo-Tuberosum by comparative analysis with an obligate short-day S.?tuberosum
ssp. Andigena accession. We show that the Neo-Tuberosum accession, but
not the Andigena, contains alleles that encode StCDF1 proteins modified
in the C-terminal region, likely to evade long day inhibition of StSP6A expression. We also identify an allele of StSP6A
from the Neo-Tuberosum accession, absent in the Andigena, which is
expressed under long days. Other leaf transcripts and metabolites that
show different abundances in tuberizing and non-tuberizing samples were
identified adding detail to tuberization-associated processes. Overall,
the data presented in this study highlight the subtle interplay between
components of the clock-CONSTANS-StSP6A axis which collectively may
interact to fine-tune the timing of tuberization.
