Murillo, O. | Hattemer, H.H.
Inheritance of isozyme variants of Alnus acuminata ssp. arguta were determined on the basis of horizontal starch gel electrophoresis procedures. Vegetative tissues from both sexually mature trees and seedlings were utilized, in order to properly assess the mode of inheritance for each of the proposed gene markers. A total of 10 isozyme systems were satisfactorily resolved. The observed variant types in zymograms are shown for each of 4 polymorphic loci (Pgi-E, Pgm-A, Mnr-A, Idh-A), as well as for the other 19 presumably monomorphic loci. The results are discussed in relation to those reported for other Alnus species. The detailed electrophoresis procedures as well as the proper inheritance analyses are presented. All 4 polymorphic loci show codominance of gene action. The electrophoretic patterns suggest a diploid-like behavior for this allotetraploid tree species.
