摘要:
The Landsberg erecta x Columbia recombinant inbred lines (RILs) of Arabidopsis have been used in order to identify and localize chromosome regions involved in the genetic control of the in vitro regeneration ability. Callus morphology (CM) and shoot regeneration (SR) traits have been considered for both leaf and root explants. The MAPMAKER analysis of leaf culture data has revealed at least one chromosome region involved with CM and several with SR, the 29-30 region of chromosome 1 being common for the two traits. Root explants did not segregate for CM but several QTLs have been detected for SR. The chromosome regions involved with leaf culture regeneration seem to be different from those of root cultures, although the regeneration of abnormal shoots in leaf explants share two chromosome regions with the regeneration of normal shoots in root cultures.
