| Mycosphaerella fijiensis is a ascomycete that causes Black Sigatoka in bananas. Recently, the M. fijiensis genome was sequenced. Repetitive sequences are ubiquitous components of fungal genomes. In most genomic analyses, repetitive sequences are associated withtransposable elements (TEs). TEs are dispersed repetitive DNA sequences found in a host genome. These elements have the ability to move from one location to another within the genome, and their insertion can cause a wide spectrum of mutations in their hosts. Some of the deleterious effects of TEs may be due to ectopic recombination among TEs of the same family. In addition, some transposons are physically linked to genes and can control their expression. To prevent possible damage caused by the... |

| Linkage grouping and ordering AFLP markers analyses were performed for two different F2 populations of carrot (Daucus carota L.). Included were 277 and 242 dominant AFLP markers and 10 and 8 co-dominant markers assigned to the nine linkage groups of Brasilia x HCM and B493 x QAL F2 populations, respectively. The overall marker datasets, includjng repulsion and coupling phases, were consistently assigned to the nine linkage groups at LOD scores ranging from 3.5 to 5.0 in both F2 populations. Linkage grouping performed with only markers linked in coupling phase showed the nine linkage groups at LOD scores ranging from 3.0 to 7.5, 3.0 to 5.5, 3.5 to 5.0 and 2.5 to 8.5 in the Brasilia-, HCM-, B493- and QAL- coupling F2 population, respectively. The average... |

| Os genes, unidades biologicas que determinam as caracteristicas de um organismo, estao contidos em moleculas de DNA presentes no nucleo das celulas. Portanto, o estudo do DNA e de fundamental importancia para o entendimento de como as caracteristicas de um organismo sao formadas. Com o grande avanco alcancado pelas tecnicas de Biologia molecular nas ultimas decadas, hoje, somos capazes de isolar e sequenciar moleculas de DNA de maneira rotineira. A partir da otimizacao das tecnicas de sequenciamento, surgiram programas com o objetivo de sequenciar genomas inteiros. atualmente, estao depositados em bancos de dados mais de 3 milhoes de sequencias de DNA e, grande parte delas ainda nao tem sua funcao conhecida. O processo de caracterizacao da funcao genica... |

| Coffea canephora, (Robusta), provides 33% of worldwide coffee production, 80% and 22% of Ugandan and Brazilian coffee production, respectively. Abiotic stress such as temperature variations or drought periods, aggravated by climate changes, are factors that affect this production. This sensitivity threatens both the steady supply of quality coffees and the livelihood of millions of people producing coffee. The natural genetic diversity of C. canephora offer a potential for detecting new genetic variants related to drought adaptation. In particular, modifications occurring in genes related to abiotic stress tolerance make these genes candidate for breeding programs in order to enhance the resilience to climate change. |

| The basidiomycetes Moniliophthora roreri and Moniliophthora perniciosa are the etiologic agents of the two most devastating diseases in cacao (Theobroma cacao ): frosty pod rot and the witches? broom, respectively. The species are very closely related and even hybrid cells have been previously obtained. In cacao, both species infect pods, causing necrosis, and M. perniciosa is also able to invade other tissues causing changes in plant metabolisms, such as hyperplasia and hypertrophy. In order to understand the molecular basis of these organisms, we sequenced the genome of these two species. We also obtained transcriptomic data (RNA-seq) in several different conditions including the interaction between cacao and both pathogens. This work reports a pipeline... |
