Mexicana; Error bars represent the standard error for each genotypic class. The x-axis shows the introgression segments; the y-axis shows trait means (Wang et al., 2010) 4.3 Modern genetic analysis of teosinte Modern genetic analysis techniques have provided deeper insights into the genetic contributions of teosinte to maize. Single-molecule long-read sequencing has revealed extensive genomic and transcriptomic variation between maize and teosinte, identifying numerous nonredundant transcript isoforms and providing a robust gene classifier for complex genomes (Li et al., 2021). Additionally, association mapping studies have identified significant associations between specific genes and trait variations in teosinte, suggesting new putative causative relationships for domestication traits (Weber et al., 2008). These advanced genetic analyses have furthered our understanding of maize domestication and provided valuable resources for utilizing teosinte germplasm in maize breeding (Huang et al., 2016).
