The genetics of glutamate oxaloacetate transaminase (GOT) in Pinus merkusii Jungh. et de Vriese
Siregar IZ, Yunanto T. (2010).Â The genetics of glutamate oxaloacetate transaminase (GOT) in Pinus merkusii Jungh. et de Vriese.Â Biodiversitas 11: 5-8. Inheritance and linkage analysis of glutamate oxalacetate transaminase (GOT) in P. merkusii were performedÂ using megagametophyte tissues of single tree seed-lots. One monomorphic locus (GOT-A)Â and three polymorphic loci (GOT-B,GOT-C and GOT-D) were identified, based on the allelic 1: 1 segregation of putatively heterozygous trees. Linkage analysis revealed that GOTCÂ andÂ GOT-DÂ wereÂ closelyÂ linkedÂ lociÂ withÂ anÂ averageÂ recombinationÂ rate (R) of about 5%. This result which is in contrast to the GOT genetics in other pine species was discussed with regard to the probably occurring gene duplication of one GOT locus.
