A research team investigated 71 citrus accessions and varieties using over 56,000 single nucleotide polymorphisms (SNPs) and 37 leaf reflectance parameters to study photosynthesis-related traits. They identified four distinct clusters of interrelated traits and found 125 genomic loci and 189 genes associated with these traits. This research provides valuable insights into the genetic and physiological mechanisms of photosynthesis, potentially leading to improved breeding and orchard management for enhanced fruit production and tree health.
