A telomere-to-telomere gapless genome reveals SlPRR1 control of circadian rhythm and photoperiodic flowering in tomato.

ABSTRACT: Cultivated tomato (Solanum lycopersicum) is a major vegetable crop of high economic value that serves as an important model for studying flowering time in day-neutral plants. A complete, continuous, and gapless genome of cultivated tomato is essential for genetic research and breeding programs. Here, we report the construction of a telomere-to-telomere (T2T) gap-free genome of S. lycopersicum cv. VF36 using a combination of sequencing technologies. The 815.27-Mb T2T "VF36" genome contained 600.23 Mb of transposable elements. Through comparative genomics and phylogenetic analysis, we identified structural variations between the "VF36" and "Heinz 1706" genomes and found no evidence of a recent species-specific whole-genome duplication in the "VF36" tomato. Furthermore, a core circadian oscil
