Ceratocystis fimbriata Ellis & Halsted recently was recorded causing seed and seedling blight on Carapa guianensis Aubl. (andiroba), a tree species native to the Amazon Rainforest and prized for its valuable timber and medicinal seed oil. C. fimbriata more commonly causes wilt type diseases in woody hosts, especially on non-native host trees. However, on andiroba the disease occurs on seedlings and seeds, affecting the species regeneration. We studied 73 isolates of C. fimbriata on andiroba from three regions of the Amazon Basin to see if they represented natural or introduced populations. Analysis of ITS rDNA sequences and phylogenetic analysis of mating type genes revealed new haplotypes of C. fimbriata from the Latin American Clade that were closely... |

Sete variedades de milho-doce sugary - (su1) originaram 21 hibridos F1's e respectivos reciprocos que, juntamente com os progenitores e duas testemunhas, foram avaliados, num delineamento em latice triplo 7x7, em Visconde de Rio Branco (MG), no ano agricola 92/93. Avaliaram-se, 25 dias apos o florescimento feminino, os seguintes caracteres: numero de espigas comerciais, peso das espigas comerciais despalhadas, comprimento da espiga, numero de fileiras de graos/espiga, umidade das sementes F2's, acucares soluveis redutores e totais das sementes F1's e F2's. Utilizou-se o metodo de analise dialelica de GARDNER e EBERHART (1966), modificado por ALVES e CRUZ (1995) para esses caracteres, com o objetivo de avaliar as variedades de milho-doce (su1) per se e em... |

The objective of this work was to evaluate the possibility of obtaining recombinant inbred wheat lines more resistant to preharvest sprouting, independently of colour genes, in three red-grained Brazilian wheat populations. The results showed statistical significance among lines within all populations, which presented a normal distribution and transgressive segregation for preharvest sprouting. The normal distribution of the lines from all red-grained populations suggests that sprouting, excluding the genes expressing seed coat pigmentation, is, probably, controlled by many genes. These findings also indicate that it may be possible to improve resistance to preharvest sprouting, independently of the colour genes. |

ABSTRACT. The genus Passiflora L. is the most representative of Passifloraceae, with over 500 known species, among which 150-200 originated from Brazil. In addition to the great commercial importance of this genus for the fruit market, many of the species have exotic flowers with a huge diversity of colors and can thereby be exploited as ornamental plants. This study was aimed at investigating the transferability of microsatellite primers in wild Passiflora species (P. cacao, P. cincinnata, P. glandulosa, P. gibertii, and P. mucronata) and characterizing 29 P. alata accessions using microsatellite primers that were previously developed in a library enriched with microsatellites from P. edulis f. flavicarpa for P. alata. The interspecies cross-amplification... |

Risks of population extinction have been estimated using a variety of methods incorporating information from different spatial and temporal scales. We briefly consider how several broad classes of extinction risk assessments, including population viability analysis, incidence functions, and ranking methods integrate information on different temporal and spatial scales. In many circumstances, data from surveys of neutral genetic variability within, and among, populations can provide information useful for assessing extinction risk. Patterns of genetic variability resulting from past and present ecological and demographic events, can indicate risks of extinction that are otherwise difficult to infer from ecological and demographic analyses alone. We provide... |
