关键词： conservation   flower-visitors   native bees   Nebraska sandhills   Penstemon   pollination   rare plant  

摘要： We studied the breeding system and pollinators of Nebraska populations of the endangered plant Blowout penstemon, Penstemon haydenii. This species appears to be one of the few known self-incompatible species of Penstemon: few self-pollinated flowers set fruit and few of these produced seeds. We found no indication that sexual reproduction was limited by inadequate pollination or resources. Pollinators were several species of native bees which varied from population to population and from year to year;there did not appear to be a consistent P. haydenii pollinator fauna. Flowers were pollinated mainly by large apid bees in the genera Habropoda and Bombus, by (mostly) smaller halictid bees, and by intermediate sized megachilid bees, particularly in the genus Osmia. One frequent flower-visitor, the presumed Penstemon specialist, Hoplitis pilosifrons (Megachilidae), may be more of a pollen-parasite than a pollinator because it commonly collected pollen into the scopa but carried very little pollen on other body parts. Management plans for conservation of Penstemon haydenii need to recognize its need for pollinators, and that the health of pollinator populations may be site-specific.

关键词： .Databases   developmental stages   Ontologies   Vocabularies  

摘要： Plant growth stages are identified as distinct morphological landmarks in a continuous developmental process. The terms describing these developmental stages record the morphological appearance of the plant at a specific point in its life cycle. The widely differing morphology of plant species consequently gave rise to heterogeneous vocabularies describing growth and development. Each species or family specific community developed distinct terminologies for describing whole-plant growth stages. This semantic heterogeneity made it impossible to use growth stage description contained within plant biology databases to make meaningful computational comparisons. The Plant Ontology Consortium (http://***) was founded to develop standard ontologies describing plant anatomical as well as growth and developmental stages that can be used for annotation of gene expression patterns and phenotypes of all flowering plants. In this article, we describe the development of a generic whole-plant growth stage ontology that describes the spatiotemporal stages of plant growth as a set of landmark events that progress from germination to senescence. This ontology represents a synthesis and integration of terms and concepts from a variety of species-specific vocabularies previously used for describing phenotypes and genomic information. It provides a common platform for annotating gene function and gene expression in relation to the developmental trajectory of a plant described at the organismal level. As proof of concept the Plant Ontology Consortium used the plant ontology growth stage ontology to annotate genes and phenotypes in plants with initial emphasis on those represented in The Arabidopsis Information Resource, Gramene database, and MaizeGDB.
