BLAST; Eucalyptus; Guava; SNPs transferability

Genome mapping is a simplified representation of molecular markers or nucleotide sequences in chromosomes; developing accurate and dense maps is crucial for marker-assisted selection. We developed and compared genetic linkage maps obtained using JoinMap 4.0 and GACD with a physical map obtained using BLAST analysis based on Eucalyptus SNPs transferred to ... more

BLAST; DNA sequence quality; PHRED; Quality window; SAGE

When analyzing sequencing reads, it is important to distinguish between putative correct and wrong bases. An open question is how a PHRED quality value is capable of identifying the miscalled bases and if there is a quality cutoff that allows mapping of most errors. Considering the fact that a low quality value does not necessarily indicate a miscalled position, we decided to ... more

BLAST; Databases; Driver

There are many bioinformatics tools that deal with input/output (I/O) issues by using filing systems from the most common operating systems, such as Linux or MS Windows. However, as data volumes increase, there is a need for more efficient disk access, ad hoc memory management and specific page-replacement policies. We propose a device driver that can be used by multiple ... more

Annotation; BLAST; Expressed sequence tags; KEGG Orthology; orthologs

The KEGG Orthology (KO) database was tested as a source for automated annotation of expressed sequence tags (ESTs). We used a control experiment where every EST was assigned to its cognate protein, and an annotation experiment where the ESTs were annotated by proteins from other organisms. Analyzing the results, we could assign classes to the annotation: correct, changed and speculated. The ... more

BLAST; Conservation measures; nrDNA; Rare species

The rare and endangered plants of any country are important genetic resources that often require urgent conservation measures. Assessment of phylogenetic relationships and evaluation of genetic diversity is very important prior to implementation of conservation strategies for saving rare and endangered plant species. We used internal transcribed spacer sequences of nuclear ribosomal DNA ... more

BLAST; Blast resistance; QTL mapping; Recombinant inbred lines; Rice

Bodao, a japonica landrace from the Taihu Lake region of China, is highly resistant to most Chinese isolates of Magnaporthe oryzea, a form of rice blast. To effectively dissect the influence of genetics on this blast resistance, a population of 155 recombinant inbred lines (F2:8) derived from a cross of Bodao x Suyunuo was inoculated with 12 blast isolates. ... more

BLAST; Chloroplast loci; DNA barcoding; Nuclear DNA marker

Genuine medicinal plant materials are very important for potential crude drug production, which can be used to cure many human diseases. DNA barcoding of medicinal plants is an effective way to identify adulterated or contaminated market materials, but it can be quite challenging to generate barcodes and analyze the data to determine discrimination power. The molecular phylogeny of a ... more

Anacardium occidentale; BLAST; Cashew; DNA fingerprinting; ITS region; PCR; extraction DNA

This study performed a genetic study of several canopies of Anacardium occidentale L. specimen called "Cashew King" (Cajueiro da Praia-PI, Brazil) in order to assess whether all canopies belong to the same plant. Leaves were collected from  different distant points, and preserved for analysis of DNA. The analysis was made from automated sequencing by capillary ... more

The family Myrtaceae is widespread in the Atlantic Forest and is well-represented in the Espírito Santo State in Brazil. In the genus Psidium of this family, guava (Psidium guajava L.) is the most economically important species. Guava is widely cultivated in tropical and subtropical countries; however, the widespread cultivation of only a small number of guava tree ... more

AFLP; Argopecten; Heterosis; Hybrid; SSR

Argopecten purpuratus and Argopecten irradians irradi­ans hybridization was successfully performed and the hybrid offspring displayed apparent heterosis in growth traits. To better understand the genetic basis of heterosis, the genomic composition and genetic varia­tion of the hybrids were analyzed with amplified fragment length poly­morphism (AFLP) and simple sequence repeat (SSR) ... more
