A method to establish an "immortalized F 2 " sporophyte population in the economic brown alga Undaria pinnatifida (Laminariales: Alariaceae)
Studies of quantitative trait loci based on genetic linkage maps require the establishment of a mapping population. Permanent mapping populations are more ideal than temporary ones because they can be used repeatedly. However, there has been no reported permanent sporophyte population of economicall...

description | Studies of quantitative trait loci based on genetic linkage maps require the establishment of a mapping population. Permanent mapping populations are more ideal than temporary ones because they can be used repeatedly. However, there has been no reported permanent sporophyte population of economically important kelp species. Based on the characteristics of the kelp life cycle, we proposed a method to establish, and then constructed experimentally, an "immortalized F
" (IF
) population of Undaria pinnatifida. Doubled-haploid "female" and "male" sporophytes were obtained through the parthenogenesis of a female gametophyte clone and the selfing of a "monoicous" gametophyte clone (originally male), respectively, and they were used as the parents. The F
hybrid line was generated by crossing the female and male gametophytes derived from the respective female and male parents. Full-sibling F
gametophyte clones, consisting of 260 females and 260 males, were established from an F
hybrid sporophyte. Thirty-five females and 35 males were randomly selected and paired to give rise to an IF
population containing 35 crossing lines. A parentage analysis using 10 microsatellite markers confirmed the accuracy of the IF
population and indicated the feasibility of this method. This proposed method may be adapted for use in other kelp species, and thus, it will be useful for genetic studies of kelp. |
