Targeted mutations of BnPAP2 lead to a yellow seed coat in Brassica napus L.
Published 2024-02-01Get full textThe yellow seed trait is preferred by breeders for its potential to improve the seed quality and commercial value of Brassica napus. In the present study, we produced yellow seed mutants using a CRISPR/Cas9 system when the two BnPAP2 homologs were knocked out. Histochemical staining of the seed coat...
