Knowledge of genetic diversity among genotypes and relationships among elite lines is of great importance for the development of breeding programs. Therefore, the objective of this study was to evaluate genetic variability based on the morphoagronomic and molecular characterization of 18 elite popcorn (Zea mays var. everta) lines to be used by Universidade Estadual ..

In this study, we analyzed dominant molecular markers to estimate the genetic divergence of 26 popcorn genotypes and evaluate whether using various dissimilarity coefficients with these dominant markers influences the results of cluster analysis. Fifteen random amplification of polymorphic DNA primers produced 157 amplified fragments, of which 65 were monomorphic and 92 were polymorphic. To cal.. Read More»

Because of human population growth, increased food production and alternatives to conventional methods of biocontrol and development of plants such as the use of endophytic bacteria and fungi are required. One of the methods used to study microorganism diversity is sequencing of the 16S rRNA gene, which has several advantages, including universality, size, and availability of databases for comp..

The purpose of this study was to analyze the genetic diversity of 15 sugary-1 sweet corn lines by microsatellite markers. One hundred pairs of simple sequence repeat primers that were mapped for field corn were tested. Of these primers, 15% were polymorphic, and all were selected for the evaluation. These primers identified a total of 39 alleles among the 15 loci that were evaluated... Read More»

Genetic diversity and structure were analyzed in 10 accessions belonging to Banco Ativo de Germoplasma de Capsicum located at Federal University of Piauí in northwestern Brazil that receives pepper samples grown in community gardens in various regions and Brazilian states. Selections were made from seeds of C. chinense (4 accessions), C. annuum (5 accessions), and C. baccatum (1 accessio.. Read More»

This study used esterases and ribosomal DNA (rDNA) markers to determine endophytic variability in order to better understand endophyte-host interactions. Polyacrylamide gel electrophoresis and esterase isoenzymes (EST; EC 3.1.1.3), with a-naphthyl acetate and β-naphthyl acetate as substrates, were used to assess relationships among endophytes. ITS1-5.8S-ITS2 sequencing data were used as rD.. Read More»

The Meliponinae are important pollinators of plant species, and one of the most managed species is Tetragonisca angustula. Initially, two subspecies were identified in T. angustula: T. angustula angustula and T. angustula fiebrigi. Subsequently, T. a. fiebrigi was considered a species, based on the coloration of its mesepisternum. The objective of the present study was to obtain genetic markers.. Read More»

The heterokaryotic and vegetative diploid phases of Colletotrichum lindemuthianum are described using nutritional and biochemical markers. Nitrate non-utilizing mutants (nit), derived from R2047, R89, R73, R65, and R23 isolates, were paired in all possible combinations to obtain heterokaryons. Although pairings R2047/R89, R2047/R73, R65/R73, and R73/R23 showed compl.. Read More»

We analyzed 80 plants of the sugarcane (Saccharum spp) variety ‘RB867515’ in order to investigate its diversity and genetic structure at the molecular level. Four simple sequence repeat (SSR) loci (UGSM51, SMC1237, SEGMS1069, and UGSM38) and five expressed sequence tag (EST)-SSR loci (ESTA68, ESTB92, ESTB145, ESTC66, and ESTC84) were used as molecular ma..

Random amplified polymorphic DNA (RAPD) markers were used to detect polymorphism and to examine relationships among four table grape clones from northwestern Paraná, in southern Brazil. The 10 primers used for RAPD fingerprints generated 126 reproducible fragments, of which 63, 68, 76, and 72 were polymorphic in cultivars Italia, Rubi, Benitaka, and Brasil, r.. Read More»
