A chromosome-scale spinach genome reveals key circadian and floral initiation gene networks linked to bolting time.
- Why it matters: Understanding the genetic basis of bolting in spinach is essential for improving yield stability, but the photoperiod-dependent flowering pathway remains poorly characterized.
- What they did: Researchers generated a high-quality reference genome for an early-bolting spinach line and integrated QTL mapping, sequence variation, and co-expression analysis to identify candidate genes and modules.
- The result: The study identified candidate loci and modules, including a circadian-associated module with SoLNK1/2 and others, providing a framework for dissecting gene networks controlling bolting in spinach.
