Whole-genome resequencing of 198 Citrus reticulata accessions for polymethoxylated flavone biosynthesis study
This project investigates the genetic architecture of polymethoxylated flavones (PMFs) biosynthesis in mandarin (Citrus reticulata) through population genomics and multi-omics integration. We collected 198 C. reticulata accessions exhibiting natural variation in PMFs content. Whole-genome resequencing was performed to characterize genetic diversity and explore the relationship between pummelo (C. maxima) genome introgression proportions and PMFs accumulation patterns. Follow-up GWAS analysis integrated with RNA-seq aims to identify candidate genes related to PMFs biosynthesis and determine genetic factors underlying natural metabolic variation in citrus populations.
