Studies on genetic diversity are useful for the description, evaluation and classification of genetic resources for preservation. The results obtained can facilitate strategies for the selection of genotypes that can be used in genetic improvement. In addition...
We present a case study of the relationship between spatial genetic structure (SGS) and age structure in Protium spruceanum (Burseraceae), an insect-pollinated, mass-fruiting, and secondary bird-dispersed tree, as determined through variation in allozyme loci.
The conservation of forests and agronomic species is essential to meet the demands of various sectors.
The LabGeM provides information that can be used as strategies for the maintenance, conservation and improvement of species with economic and ecological interests.
Studies on population genetics developed at LabGeM help quantifying genetic diversity within and between plant populations.
For example, studies to determine seed collection from mature trees to support the recovery of degraded areas, including tree populations that have underwent significant reduction in population size.
Also, we are determining priority populations for conservation so we can characterize divergent genotypes for breeding proposals.
For this, we use DNA molecular markers to distinguish genotypes by analyzing the nucleotide sequences, even allowing paternity testing.
Molecular markers are classified into dominant and codominant. Suggested reading here.
