CpDll, encoding an HD-Zip I transcription factor, positively regulates formation of deeply lobed leaf shape in zucchini, Cucurbita pepo, which is associated with sequence variation in its promoter region. Leaf shape is an important horticultural trait in zucchini (Cucurbita pepo L.). Deeply lobed leaves have potential advantages for high-density planting and hybrid production. However, little is known about the molecular basis of deeply lobed leaf formation in this important vegetable crop. Here, we conducted QTL analysis and fine mapping of the deeply lobed leaf (CpDll) locus using recombinant inbred lines and large F
