“…1 Different methods of multivariate analysis use morphological variations of plants in estimation of genetic divergence, and among them are clustering methods. The use of multivariate techniques allows evaluation of genetic material from a set of characteristics considering the importance of each variable in the total variation (COSTA et al, 2016;MENEGATTI et al, 2017). Thus, knowledge about similarity and dissimilarity may contribute to the rational planning of genetic breeding programs and optimization of the management of the preserved germplasm, which contributed to the knowledge of the phenotypic variation and divergence patterns of the species (FIGÁS et al, 2018).…”

Morphological Characterization and Genetic Diversity in Ornamental Specimens of the Genus Sansevieria

et al. 2020

The aim of this study was to characterize and estimate genetic divergence among twelve specimens of the Sansevieria genus from the collection of the Universidade Federal do Piauí (UFPI). A completely randomized experimental design was used with three replicates, and the plot consisted of four plants. In morphological characterization, qualitative and quantitative descriptors of leaves were evaluated. Genetic divergence among the specimens was determined by the Tocher clustering method and the hierarchical UPGMA. There is genetic variation among specimens evaluated, which was also expressed by the variability of colors, shapes, and sizes of the leaves. The Tocher clustering method and the hierarchical UPGMA were effective in differentiation of the specimens from multi-categorical qualitative descriptors, as the Tocher method grouped the accessions in two groups and the UPGMA in seven different groups. We highlight the accessions SSV 09 and SSV 10 as exhibiting the highest mean values in weekly leaf growth and in leaf height, important characteristics for local sale and for export.

“…In studying the genetic structure of Casearia grandiflora in conserved and disturbed populations, there was observed moderate divergence between populations (F ST = 0.14) and higher proportion of genetic diversity (85 %) was distributed within populations, which were not structured. In addition, less urbanized populations had greater genetic diversity, confirming the effectiveness of protected areas in genetic diversity conservation (Costa et al 2017).…”

Microsatellites are important for forest genetic resources conservation in Brazilian biomes

et al. 2023

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.

“…In Brazil, the genetic characterisation of seed source populations of native trees is routinely performed using genetic markers, such as morphological (COSTA et al, 2016;ROVERI NETO;PAULA, 2017;CORREIA et al, 2019;FELIX et al, 2020) and/or DNA (or molecular) analysis. Commonly used markers are Random Amplified Polymorphic DNA (RAPD) (RABBANI; SILVA-MANN;FERREIRA, 2012;BELARMINO et al, 2017;ALMEIDA NETO et al, 2019) and Inter Simple Sequence Repeats (ISSR) (DUARTE;VIEIRA, 2018;SILVA JÚNIOR et al, 2017).…”

SEED QUALITY AND GENETIC DIVERSITY OF A CULTIVATED POPULATION OF Mimosa caesalpiniifolia BENTH

et al. 2020

Mimosa caesalpiniifolia Benth. (Fabaceae) is a native tree of the dry tropical forests of northeastern Brazil and can be exploited for logging and reforestation purposes. This study evaluated the physiological quality of seeds and the genetic diversity of a cultivated population of M. caesalpiniifolia, against the background of potential commercial seed production. Nine trees were used in the study. The quality of their seeds was evaluated by germination and vigour tests, and their genetic diversity was accessed using Inter Simple Sequence Repeat (ISSR). The studied tree group presents a moderate genetic diversity and produces seeds with high physiological quality, but with subtle vigour differences, which can be detected by electrical conductivity and potassium leaching tests. Our results suggest that these trees are potentially suitable for commercial seed production.
