Introdução: A constipação é uma doença crônica que afeta a população mundial, podendo ser consequência do desequilíbrio da microbiota intestinal, conhecida como disbiose. Nesse contexto, os probióticos vêm sendo utilizados com o objetivo de promover o seu equilíbrio, a fim de mantê-la saudável (eubiose). Objetivo: Avaliar, em um estudo duplo-cego,...
Patent
Full-text available
The present invention relates to methodology and constructs for modifying plant architecture and enhancing plant biomass and/or sucrose yield.
Article
Transposable elements (TEs) are considered to be important components of the maintenance and diversification of genomes. The recent increase in genome sequence data has created an opportunity to evaluate the impact of these active mobile elements on the evolution of plant genomes. Analysis of the sugarcane transcriptome identified 267 clones with s...

The maize Mutator ( Mu) system has been described as the most active and mutagenic plant transposon so far discovered. Mu -like elements (MULEs) are widespread among plants, and many and diverse variants can coexist in a particular genome. The autonomous regulatory element MuDR contains two genes: mudrA encodes the transposase, while the function o...

To contribute to our understanding of the genome complexity of sugarcane, we undertook a large-scale expressed sequence tag (EST) program. More than 260,000 cDNA clones were partially sequenced from 26 standard cDNA libraries generated from different sugarcane tissues. After the processing of the sequences, 237,954 high-quality ESTs were identified...

A large sugarcane EST (expressed sequence tag) project recently gave us access to 261,609 EST sequences from sugarcane, assembled into 81,223 clusters. Among these, we identified 88 resistance gene analogs (RGAs) based on their homology to typical pathogen resistance genes, using a stringent BLAST search with a threshold e-value of e(-50). They inc...

The sugarcane expressed sequence tag (SUCEST) project has produced a large number of cDNA sequences from several plant tissues submitted or not to different conditions of stress. In this paper we report the result of a search for transposable elements (TEs) revealing a surprising amount of expressed TEs homologues. Of the 260,781 sequences grouped...

Retrolycl, a Ty1/copia-like element, was originally isolated from the Lycopersicon peruvianum genome and shown to be present also in other Lycopersicon species. It shares extensive similarities with Tntl, except in its U3 regulatory region. In order to evaluate Retrolycl diversity, we analyzed partial sequences including both coding domains and the...
Article
Retrotransposons are ubiquitous mobile genetic elements that transpose through an RNA intermediate. One of the best known plant retrotransposon, Tnt1, was isolated from tobacco and showed an extensive distribution in the Nicotiana genus. We investigated the presence of related sequences in the Lycopersicon genus, another member of the Solanaceae fa...
