Fine Mapping to Identify the Functional Genetic Locus for Red Coloration in Pyropia yezoensis Thallus.

ABSTRACT: Pyropia yezoensis, commonly known as "Nori" or "Laver" is an economically important marine crop. In natural or selected populations of P. yezoensis, coloration mutants are frequently observed. Various coloration mutants are excellent materials for genetic research and study photosynthesis. However, the candidate gene controlling the Pyropia coloration phenotype remains unclear to date. QTL-seq, in combination with kompetitive allele-specific PCR (KASP) and RNA-seq, can be generally applied to population genomics studies to rapidly identify genes that are responsible for phenotypes showing extremely opposite traits. Through cross experiments between the wild line RZ and red-mutant HT, offsprings with 1-4 sectors chimeric blade were generated. Statistical analyses reveal
