The correct name for an Aquilegia (Ranunculaceae) hybrid of the parentage Aquilegiaflavescens × A.formosa.

ABSTRACT: Aquilegia×miniana (J.F.Macbr. & Payson) Cronk, hybr. & stat. nov. is the correct name for the hybrid Aquilegiaflavescens S.Watson × A.formosaFisch. & DC.var.formosa. In 1916 Payson and Macbride, while exploring the mountains of Idaho, found populations of Aquilegia that were pink in flower colour and appeared intermediate between the yellow-flowered A.flavescens and red-flowered A.formosa. They named these plants A.flavescensvar.miniana J.F.Macbr. & Payson. There has been uncertainty over whether their type collections (in GH, RM, MO, US, E, CM, CAS, NY) do indeed represent hybrids or pink-flowered morphs of A.flavescens. Using a Wells diagram, the holotype (in the Gray Herbarium of Harvard University) is shown to be intermediate, allowing its identification as a clear hybrid. However, some of the isotype material is indistinguishable from A.flavescens. The holotype matches material from British Columbia that has been determined to be of hybrid origin using molecular and morphological data. A.flavescensvar.miniana J.F.Macbr. & Payson is, therefore, an available name for the hybrid, which is here raised to the status of hybrid binomial.

Project description:BackgroundThe lower eudicot genus Aquilegia, commonly known as columbine, is currently the subject of extensive genetic and genomic research aimed at developing this taxon as a new model for the study of ecology and evolution. The ability to perform functional genetic analyses is a critical component of this development process and ultimately has the potential to provide insight into the genetic basis for the evolution of a wide array of traits that differentiate flowering plants. Aquilegia is of particular interest due to both its recent evolutionary history, which involves a rapid adaptive radiation, and its intermediate phylogenetic position between core eudicot (e.g., Arabidopsis) and grass (e.g., Oryza) model species.ResultsHere we demonstrate the effective use of a reverse genetic technique, virus-induced gene silencing (VIGS), to study gene function in this emerging model plant. Using Agrobacterium mediated transfer of tobacco rattle virus (TRV) based vectors, we induce silencing of PHYTOENE DESATURASE (AqPDS) in Aquilegia vulgaris seedlings, and ANTHOCYANIDIN SYNTHASE (AqANS) and the B-class floral organ identity gene PISTILLATA in A. vulgaris flowers. For all of these genes, silencing phenotypes are associated with consistent reduction in endogenous transcript levels. In addition, we show that silencing of AqANS has no effect on overall floral morphology and is therefore a suitable marker for the identification of silenced flowers in dual-locus silencing experiments.ConclusionOur results show that TRV-VIGS in Aquilegia vulgaris allows data to be rapidly obtained and can be reproduced with effective survival and silencing rates. Furthermore, this method can successfully be used to evaluate the function of early-acting developmental genes. In the future, data derived from VIGS analyses will be combined with large-scale sequencing and microarray experiments already underway in order to address both recent and ancient evolutionary questions.
