O. Murillo et Hh. Hattemer, INHERITANCE OF ISOZYME VARIANTS OF ALNUS-ACUMINATA SSP ARGUTA (SCHLECTENDAL) FURLOW, Silvae Genetica, 46(1), 1997, pp. 51-55
Inheritance of isozyme variants of Alnus acuminata ssp. arguta were de
termined on the basis of horizontal starch gel electrophoresis procedu
res. 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 d
etailed electrophoresis procedures as well as the proper inheritance a
nalyses are presented. All 4 polymorphic loci show codominance of gene
action. The electrophoretic patterns suggest a diploid-like behavior
for this allotetraploid tree species.
