Asymmetric introgressive hybridization among Louisiana iris species. Genes, 1(1), pp. 9-22.2073-4425https://hdl.handle.net/10877/13793In this review, we discuss findings from studies carried out over the past 20+ years that document the occurrence of asymmetric introgressive hybridization in a plant clade. In particular, analyses of natural and experimental hybridization have demonstrated the consistent introgression of genes from Iris fulva into both Iris brevicaulis and Iris hexagona. Furthermore, our analyses have detected certain prezygotic and postzygotic barriers to reproduction that appear to contribute to the asymmetric introgression. Finally, our studies have determined that a portion of the genes transferred apparently affects adaptive traits.Text14 pages1 file (.pdf)enasymmetric introgressive hybridizationLouisiana irisessegregation distortionnatural hybrid zonesBiologyArticle© 2010 The Authors.https://doi.org/10.3390/genes1010009This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.
