ABSTRACT: The aim of this study was to estimate the genetic divergence of twelve maize hybrids grown in Cerrado-Pantanal ecotone, based on nine agronomic traits and using the Ward-MLM procedure. The experiment was installed at Universidade Estadual de Mato Grosso do Sul, Aquidauana Unit, in a randomized blocks design with four replications. The following traits were measured: plant height, ear insertion height, ear diameter, ear length, stem diameter, number of kernels per rows, number of rows per ear, weight of hundred grains and grain yield. The significance of the nine traits was analyzed by F test at 5% probability. Data were simultaneously analyzed using the Ward-MLM to compose the hybrids groups through the cluster. There was genetic variability among the maize hybrids assessed. Hybrids with high heterotic effect can be obtained by crossing individuals of the group II with group III. RESUMO: O objetivo deste trabalho foi estimar a divergência genética usando o procedimento Ward-MLM em 20 híbridos de milho cultivados no ecótono Cerrado-Pantanal baseada em nove caracteres agronômicos. O experimento foi instalado na Universidade Estadual de Mato Grosso do Sul, Unidade de Aquidauana Unit, em um delineamento de blocos casualizados com quatro repetições. Mensuraram-se os seguintes caracteres: altura de plantas; altura de inserção da primeira espiga; diâmetro da espiga; diâmetro do colmo; número de grãos por fileira; número de fileiras por espiga; peso de 100 grãos; e produtividade. A significância dos nove caracteres foi analisada pelo teste F a 5% de probabilidade. Os dados foram analisados simultaneamente usando o procedimento Ward-MLM para compor os grupos de híbridos por meio da análise de agrupamento. Existe variabilidade genética entre os híbridos de milho avaliados. Híbridos com alto efeito heterótico podem ser obtidos do cruzamento ente indivíduos contidos no grupo I com os do grupo II.

Abstract: Microorganisms dominate most of Antarctic ecosystems and play a crucial role in their functioning. They are called extremophilic microorganisms with unique and versatile metabolic properties with possible biotechnological applications in several areas. The aim of the present study was to identify psychrotolerant microorganisms from Antarctic continent samples and to screen them for antimicrobial effects. Phylogenetic analyses revealed that most isolates were closely related to recognized species, including those recovered previously from Antarctica, which belonged to the major phyla Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria (classes Alpha, Beta, and Gammaproteobacteria). A total of 326 bacterial isolates, distributed in 39 different genera, were recovered and identified based on sequencing of the 16S rRNA gene. The main representative genera were Arthrobacter, Psychrobacter, Pseudoalteromonas, and Rhodococcus. Antimicrobial screening revealed fifteen isolates capable of inhibiting growth of at least one of the indicator strains: Escherichia coli, Micrococcus luteus, Staphylococcus aureus, Bacillus subtilis, and Candida albicans. One psychrotolerant bacterium, Pseudomonas sp. isolate 99, showed a broad antimicrobial range, in addition to antiproliferative and antiparasitic activity. Overall, the small number of antibiotic-producing isolates obtained and the weakness of their inhibition halos corroborated previous findings suggesting that cold-loving bacteria from Antarctica are not as good as their relatives from mesophilic environments for antimicrobial prospecting. Nonetheless, antiproliferative and antiparasitic results observed are promising and suggest that there is an untapped wealth in Antarctic environments for bioprospecting compounds with pharmaceutical potential application.
