Gene Mapping and Molecular Marker Development for Controlling Purple-Leaf Trait in Pakchoi (<i>Brassica rapa</i> subsp. <i>chinensis</i> (L.) Hanelt).

ABSTRACT:

Backgrounds

purple pakchoi (Brassica rapa subsp. chinensis (L.) Hanelt) is rich in anthocyanins, which contribute to its significant edible, ornamental, and potential health-promoting value. Fine mapping of the genes responsible for the purple-leaf trait is essential for establishing molecular marker-assisted breeding and facilitating genetic improvement.

Methods

In this study, we used the inbred purple-leaf line 'PQC' and green-leaf line 'HYYTC' as parents to construct a six-generation genetic segregation population. We analyzed the inheritance pattern of the purple-leaf trait and combined Bulked Segregant Analysis Sequencing (BSA-Seq) with penta-primer amplification refractory mutation system (PARMS) to map the causal gene.
