摘要: Sex expression in gynodioecious plants is often governed by an interaction between maternally inherited cytoplasmic male sterility (CMS) genes and nuclear fertility restorer genes. Previous studies have documented association females molecular markers the genomes natural populations, suggesting that these are associated with different CMS types. We analyzed spatial distributions of mitochondrial chloroplast alleles sexual phenotype individuals within five Alaskan populations Silene acaulis. Within two alleles, but not sex, were clustered at a scale ≤2 m. suggest this pattern generated short‐distance dispersal (and CMS) through seed longer‐distance restorers both pollen seed. also investigated whether sex ratio changed time (across size classes), as might be...
