The Genus Antirrhinum (Snapdragon): A Flowering Plant Model …
Whereas cultivated A. majus and some wild species (e.g., Antirrhinum valentinum, Antirrhinum subbaeticum, and Antirrhinum siculum) are self-fertile, the majority of Antirrhinum species show gametophytic self-incompatibility that is determined by a single, complex S locus.
A phylogeny of Antirrhinum reveals parallel evolution of alpine ...
2021年6月25日 · The genus Antirrhinum is separated into three morphological subsections (Rothmaler, 1956), with species from the two largest subsections, Kickxiella and Antirrhinum, showing suites of traits adaptive to contrasting environments.
An everlasting pioneer: the story of Antirrhinum research
2003年8月1日 · We ask what made Antirrhinum attractive to the earliest students of variation and inheritance, and how its use led to landmark advances in plant genetics and to our present understanding of plant...
The Antirrhinum genus used to be a classic model for flowering plants before the epoch of Arabidopsis. In fact, its history of being a research workhorse is very long, tracing back to the...

Low Levels of Allozyme Variability in the Threatened Species
2004年10月11日 · Antirrhinum subbaeticum, with only four populations and an overall total population lower than 500 individuals (Jiménez et al., 2002), is considered as endangered. Antirrhinum pertegasii, with no more than 10 populations and an overall total population estimated as less than 200 individuals (VV.AA., 2000), is considered as vulnerable.
