Sporisorium scitamineum is a biotrophic fungus responsible for the sugarcane smut, worldwide spread disease. This study provides complete sequence of individual chromosomes S. from telomere to achieved by combination PacBio long reads and Illumina short data, as well draft second fungal strain. Comparative analysis previous available sequences another strain detected few polymorphisms among three genomes. The novel described herein allowed us identify annotate extended subtelomeric regions,...
The Cylindrospermopsis raciborskii population from Brazilian freshwater is known to produce saxitoxin derivatives (STX), while cylindrospermopsin (CYN), which commonly detected in isolates Australia and Asia continents, has thus far not been South American strains. However, during the investigation for presence of cyrA, cyrB, cyrC cyrJ CYN synthetase genes genomes four laboratory-cultured C. strains, almost complete cyrA gene sequences were obtained all cyrB fragments observed two These...
The purpose of this work was to study a rapid yeast DNA extraction by boiling and freeze-thawing processes without using chemical reagents or any purification procedures, obtain high grade PCR-product. A specific fragment the 18S region Dekkera bruxellensis Saccharomyces cerevisiae chosen. described protocols generated PCR-grade product preparations could be used process many samples. amplification fragments observed after 30 35 cycles. These kind reagents, especial water, procedures proved...
Sugarcane smut disease is caused by the biotrophic fungus Sporisorium scitamineum. The characterized development of a whip-like structure from primary meristems, where billions teliospores are produced. also causes tillering and low sucrose high fiber contents, reducing cane productivity. We investigated biological events contributing to symptoms in intermediate-resistant sugarcane genotype examining transcriptional profiles (RNAseq) shortly after inoculating plants immediately whip...
Sugarcane smut disease, caused by the biotrophic fungus Sporisorium scitamineum, is characterized development of a whip-like structure from plant meristem. The disease causes negative effects on sucrose accumulation, fiber content and juice quality. aim this study was to exam whether transcriptomic changes already described during infection sugarcane S. scitamineum result in at metabolomic level. To address question, an analysis conducted initial stage interaction through progression...
Cylindrospermopsis raciborskii is a freshwater cyanobacterial species with increasing bloom reports worldwide that are likely due to factors related climate change. In addition the deleterious effects of blooms on aquatic ecosystems, majority ecotypes can synthesize toxic secondary metabolites causing public health issues. To overcome harmful C. blooms, it important advance knowledge diversity, genetic variation, and evolutionary processes within populations. An efficient approach exploring...
Alternative splicing (AS) promotes transcriptome and proteome diversity during growth, development, stress responses in eukaryotes. Genome-wide studies of AS sugarcane (Saccharum spp.) are lacking, mainly due to the absence a high-quality sequenced reference genome, sugarcane's large, complex variable chromosome numbers polyploidy cultivars. Here, we analyzed changes isoform-level landscape infection with smut fungus (Sporisorium scitamineum) using hybrid approach involving Sorghum bicolor...
Sporisorium scitamineum is a biotrophic fungus causing sugarcane smut disease. In this study, we set up pipeline and used genomic dual transcriptomic data previously obtained by our group to identify candidate effectors of S. their expression profiles in infected smut-resistant susceptible plants. The profile different genes after infection contrasting genotypes assessed RT-qPCR depended on the plant disease progression. Three effector expressed earlier only resistant plants, four both...
Microcystis aeruginosa strain SPC777 is an important toxin-producing cyanobacterium, isolated from a water bloom of the Billings reservoir (São Paulo State, Brazil). Here, we report draft genome sequence and initial findings preliminary analysis SPC777, including several gene clusters involved in nonribosomal ribosomal synthesis secondary metabolites.
O recente interesse pelo consumo de amoras-pretas ( Rubus spp .) associado a adaptacao da cultura algumas regioes do pais, tem proporcionado ampliacao area producao fruto, principalmente no Estado Rio Grande Sul e em outras com condicoes climaticas semelhantes. Os frutos, coloracao negra sabor acido doce-acido, sao ricos compostos nutraceuticos , podendo ser destinados tanto ao in natura quanto processo industrial, como o preparo suco, polpa, geleia doces. Quando necessitam, entanto,...

The indiscriminate use of pesticides on grape crops is harmful for consumers´ healthin “in natura” consumption and in the ingestion wine juice. During winemaking, a rapid efficient fermentation stage critical to avoid proliferation contaminating microorganisms guarantee product´s quality. Polymerase chain reaction (PCR) has advantage detecting these contaminants early stages fermentation. However,this enzymatic may also be susceptible specific problems, reducing its efficiency. Agricultural...
The aim of this work was to study the production functional protein in yeast culture. cells Saccharomyces cerevisiae Embrapa 1B (K+R+) killed a strain 26B (K-R-)in grape must and YEPD media. lethal effect toxin-containing supernatant aeration upon killer correlation between products anaerobic metabolism toxin formation were evaluated. results showed that at low sugar concentration, Sacch. only produced under conditions . system be regulated by Pasteur Crabtree effects. As soon as ethanol...
Abstract Background The white-eared opossum ( Didelphis albiventris ) is widely distributed throughout Brazil and South America. It has been used as an animal model for studying different scientific questions ranging from the restoration of degraded green areas to medical aspects Chagas disease, leishmaniasis resistance against snake venom. As a marsupial, D. can also contribute understanding molecular mechanisms that govern stages organogenesis. Opossum joeys are born after only 13 days,...
