Outline of Final Research Achievements |
Osmunda lancea has morphological adaptations that allow it to grow along streams where it is frequently submerged. One such adaptation is stenophylly. Another adaptation is their short sterile fronds with thick petioles. Although these morphological traits were segregated in doubled haploids and F2 hybrids that originated from a putative F1 hybrid between O. lancea and O. japonica, they are strongly correlated. Map-based analysis using doubled haploids and F2 hybrids revealed a locus on linkage group 10 that appeared to be associated with the angle of the pinna base. It was also suggested that several other genes affecting stenophylly were present on other linkage groups, accounting for the phenotypic correlation observed between adaptive traits.
