“…The coancestry coefficient was 0.180, similar to the expected for half-sib progenies (0.125). Based on these results, the authors estimated that 62 adult trees are needed for seed collection for short-term conservation (Francisco et al 2018).…”

Microsatellites are short sequence repeats that make up the genomes of eukaryotes and prokaryotes. They are of great importance as DNA markers for studies in several fields of genetics. In the present review, we searched for studies published in the five years period of 2017 to 2021 regarding the use of microsatellites in studies with forest tree species from the Brazilian biomes, in order to examine the importance of these markers for forest resources conservation. We searched scientific papers in journals indexed on the Scopus and Web of Science databases. There were found 38 peer reviewed articles that used microsatellites in the Brazilian biomes. The Atlantic Forest was the biome with more studies (35.9 %) and most of the studies were published in 2018 (34.2 %). In addition, most of the studied species belonged to the Fabaceae family (34.2 %). The conclusions and recommendations made in these studies ratify the great contribution of microsatellite markers in the conservation of native forest species in Brazilian biomes.

“…Unlike the present study, Butcher et al (2005) obtained outcrossing rates of 𝑡 𝑚 < 0.7 and did not detect evidence of selfing for E. benthamii. However, variations in the mating system pattern of a species can be explained by environmental and genetic factors (Francisco et al, 2018), with different individuals, populations, and even reproductive events showing variations in rates of selfing (Tambarussi et al, 2016;Tambarussi et al, 2017).…”

Eucalyptus benthamii is an important species used in monoclonal and hybrid forest plantations around the world. Few natural populations of the species remain, and as such it has been placed on the list of endangered species. We sampled 111 seeds of Eucalyptus benthamii from nine progenies across two provenances (Candói - two progenies; Vale do Corisco - seven progenies). Samples were genotyped using 19 microsatellite loci. A high number of alleles (from 80 to 114) were found in the studied progenies.

Better-informed mangrove conservation and management practices are needed as the ecosystem services provided by these intertidal forests continue to be threatened by increasing anthropogenic pressures and climate change. Multiple layers of knowledge are required to achieve this goal, including insights into population genetics of mangrove species. Understanding the importance of population-genetic insights to conservation, multiple research groups have developed microsatellite loci for the widespread, neotropical red mangrove, Rhizophora mangle. However, although a wealth of genetic markers exist, empirical research is limited in the number of these loci employed. Here, we designed two multiplex PCR panels that combine seven novel loci developed for this work and eight previously-developed loci from three research groups to generate 15-locus genotypes, more than twice the average number of loci used in previous research, in only two PCR. We demonstrated utility in R. mangle from four sites across ~ 2500 km near this species' northern latitudinal limits, and that these multiplex panels were better able to delineate populations than data subsets with numbers of loci comparable to previous research. We focus our discussion on how this tool is a more-informative, efficient (both in terms of time and resources), and easily-modifiable alternative to address many pressing conservation and management issues, such as the generation of baseline genetic data for areas not yet studied, better defining management units, and monitoring genetic effects of restoration projects. We also provide a quick protocol that outlines each step in this procedure to facilitate the use of this tool by others.
