A longitudinal comparison of 305 toluene diisocyanate (TDI) and 581 hydrocarbons workers employed at a Texas chemical manufacturing facility from 1971 through 1997 tested whether workplace exposure to TDI was associated with changes in any of the respiratory measures collected by the company's health surveillance program. Mean TDI exposures measured 96.9(More)
Brassica carinata (bbcc) was resynthesized by protoplast fusion betweenB. nigra (bb) andB. oleracea (cc). In two fusion experiments 64 hybrid plants were obtained and identified to be true hybrids by isoenzyme analysis, nuclear DNA content, chromosome number, and intermediate morphology. Of these plants 56% were normal amphidiploids with 2n=34 chromosomes(More)
Prunus salicina is one of the most economically important stone fruits. However, there is scarce genetic information available, which makes it difficult to implement marker-assisted selection (MAS) in genetic improvement programs. Recently, next-generation sequencing has greatly enhanced breeding program strategies, generating information associated with(More)
When trying to discover knowledge on a collection of data, one of the first arising tasks is to identify groups of similar objects, that is, to carry out cluster analisys for obtaining data partitions. There are several clustering methods that can be used for cluster analisys. Yet, for a given data set, each clustering metod may identify groups whose member(More)
The potential impact of genetically modified (GM) crops on biodiversity is one of the main concerns in an environmental risk assessment (ERA). The likelihood of outcrossing and pollen-mediated gene flow from GM crops and non-GM crops are explained by the same principles and depend primarily on the biology of the species. We conducted a national-scale study(More)
Transcription factors R2R3MYB family have been associated with the control of secondary metabolites, development of structures, cold tolerance and response to biotic and abiotic stress, among others. In recent years, genomes of Rosaceae botanical family are available. Although this information has been used to study the karyotype evolution of these species(More)
Japanese plum (Prunus salicina L.) is a fruit tree of the Rosaceae family, which is an economically important stone fruit around the world. Currently, Japanese plum breeding programs combine traditional breeding and plant physiology strategies with genetic and genomic analysis. In order to understand the flavonoid pathway regulation and to develop molecular(More)
A national-scale study of outcrossing potential within Chilean vascular flora was conducted using an upgraded algorithm, which adds parameters such as pollinator agents, climate, and geographic conditions. Datasets were organized and linked in a Web platform (, in which the development of a total outcrossing potential (TOP) predictor was(More)
Flavonoids are responsible of different fruit sensorial properties. In Japanese plum (Prunus salicina L.) these compounds are variable in both type and quantity during the different stages of fruit growth and maturation. Here we present the first study which determines the expression profile of structural genes of the flavonoid pathway and accumulation(More)
