1. Genetic diversity among Brazilian okra landraces detected by morphoagronomic and molecular descriptors
ABSTRACT. The conservation of okra landraces [Abelmoschus esculentus (L.) Moench] in gene banks is essential for the success of their use in breeding programmes. This study evaluated the genetic diversity among okra landraces in Brazil based on morphoagronomic descriptors and AFLP markers. We studied 30 accessions of the vegetable gene bank of the Universida

2. AVANÇOS RECENTES EM BIOSSÍNTESE COMBINATÓRIA DE POLICETÍDEOS: PERSPECTIVAS E DESAFIOS
Natural products continue to inspire scientists on the search for biological active structures. Recent advances in synthetic biology allow modifying genes to extend structural diversity present on natural products by changing important functional groups guided through genetic information. In this context, polyketides synthases (PKS) represent a class of enzy

3. Comet and cytogenetic tests as tools for evaluating genomic instability in seeds of Oryza sativa L. and Phaseolus vulgaris L. from gene banks
Abstract This study aimed to assess the feasibility of comet and cytogenetic tests as tools for evaluating genomic instability in seeds of Oryza sativa L. (rice) and Phaseolus vulgaris (beans) L. from gene banks. Rice and beans were exposed to methyl methanesulfonate (MMS) as a reference DNA damaging agent. Seeds of two accessions of rice and beans were obta

4. Internal control for real-time polymerase chain reaction based on MS2 bacteriophage for RNA viruses diagnostics
BACKGROUND Real-time reverse transcription polymerase chain reaction (RT-PCR) is routinely used to detect viral infections. In Brazil, it is mandatory the use of nucleic acid tests to detect hepatitis C virus (HCV), hepatitis B virus and human immunodeficiency virus in blood banks because of the immunological window. The use of an internal control (IC) is

5. Molecular characterization of microbial contaminants isolated from Umbilical Cord Blood Units for transplant
ABSTRACT Disposal of Umbilical Cord Blood Units due to microbial contamination is a major problem in Cord Blood Banks worldwide as it reduces the number of units available for transplantation. Additionally, economic losses are generated as result of resources and infrastructure used to obtain such units. Umbilical Cord Blood Units that showed initial microbi

6. Impact of a confirmatory RhD test on the correct serologic typing of blood donors
BACKGROUND: The RHD gene is highly polymorphic, which results in a large number of RhD variant phenotypes. Discrepancies in RhD typing are still a problem in blood banks and increase the risk of alloimmunization. In this study, the RhD typing strategy at a blood bank in Brazil was evaluated.METHODS: One-hundred and fifty-two samples typed as RhD negative and

12. Extracting samples of high diversity from thematic collections of large gene banks using a genetic-distance based approach.
Background Breeding programs are usually reluctant to evaluate and use germplasm accessions other than the elite materials belonging to their advanced populations. The concept of core collections has been proposed to facilitate the access of potential users to samples of small sizes, representative of the genetic variability contained within the gene pool of
