Sporophytic self-incompatibility in Senecio squalidus L (Asteraceae)--the search for S.
Hiscock SJ, McInnis SM, Tabah DA, Henderson CA, Brennan AC. Hiscock SJ, et al. J Exp Bot. 2003 Jan;54(380):169-74. doi: 10.1093/jxb/erg005. J Exp Bot. 2003. PMID: 12456767 Review.
Senecio squalidus (Oxford Ragwort) is being used as a model species to study the genetics and molecular genetics of self-incompatibility (SI) in the Asteraceae. ...Together these data suggest that SSP is a strong candidate for a Senecio S-gene....

Pollen-pistil interactions and self-incompatibility in the Asteraceae: new insights from studies of Senecio squalidus (Oxford ragwort).
Allen AM, Thorogood CJ, Hegarty MJ, Lexer C, Hiscock SJ. Allen AM, et al. Ann Bot. 2011 Sep;108(4):687-98. doi: 10.1093/aob/mcr147. Epub 2011 Jul 12. Ann Bot. 2011. PMID: 21752792 Free PMC article. Review.
Early structural and cytological studies in these two families suggested that pollen-pistil interactions and SSI were similar, if not the same. Recent cellular and molecular studies in Senecio squalidus (Oxford ragwort) have challenged this belief by revealing that …

Rapid homoploid hybrid speciation in British gardens: The origin of Oxford ragwort (Senecio squalidus).
Nevado B, Harris SA, Beaumont MA, Hiscock SJ. Nevado B, et al. Mol Ecol. 2020 Nov;29(21):4221-4233. doi: 10.1111/mec.15630. Epub 2020 Sep 26. Mol Ecol. 2020. PMID: 32911573
In this work we analyse genome-wide polymorphism data obtained by transcriptome sequencing of the British hybrid species Oxford ragwort (Senecio squalidus, Asteraceae), its two Italian parental species (S. aethnensis and S. chrysanthemifolius) and their naturally oc …

Genetic control of self-incompatibility in Senecio squalidus L. (Asteraceae): a successful colonizing species.
Hiscock SJ. Hiscock SJ. Heredity (Edinb). 2000 Jul;85 ( Pt 1):10-9. doi: 10.1046/j.1365-2540.2000.00692.x. Heredity (Edinb). 2000. PMID: 10971686
Senecio squalidus (Oxford ragwort) is a well-known introduction to the British flora that has proved to be an extremely successful colonist over the last 150 years. Unusually for a colonizing species, S. squalidus is self-incompatible (SI). Being a member of …

Sporophytic self-incompatibility in Senecio squalidus (Asteraceae): S allele dominance interactions and modifiers of cross-compatibility and selfing rates.
Brennan AC, Tabah DA, Harris SA, Hiscock SJ. Brennan AC, et al. Heredity (Edinb). 2011 Jan;106(1):113-23. doi: 10.1038/hdy.2010.29. Epub 2010 Apr 7. Heredity (Edinb). 2011. PMID: 20372180 Free PMC article.
This allows complex patterns of independent S allele dominance interactions in male (pollen) and female (pistil) reproductive tissues. Senecio squalidus is a useful model for studying the genetic regulation and evolution of SSI because of its population history as a …

Population genetics of sporophytic self-incompatibility in Senecio squalidus L. (Asteraceae) II: a spatial autocorrelation approach to determining mating behaviour in the presence of low S allele diversity.
Brennan AC, Harris SA, Hiscock SJ. Brennan AC, et al. Heredity (Edinb). 2003 Nov;91(5):502-9. doi: 10.1038/sj.hdy.6800315. Heredity (Edinb). 2003. PMID: 14576744
We recently estimated that as few as six S alleles represent the extent of S locus diversity in a British population of the self-incompatible (SI) coloniser Senecio squalidus (Oxford Ragwort). Despite the predicted constraints to mating imposed by such a low number …

To quantify and qualify divergence associated with recent homoploid hybrid speciation, we compared quantitative trait (QT) and molecular genetic variation between the homoploid hybrid species Senecio squalidus and its parental species, S. aethnensis and S. chrysanth …

Recent, allopatric, homoploid hybrid speciation: the origin of Senecio squalidus (Asteraceae) in the British Isles from a hybrid zone on Mount Etna, Sicily.
James JK, Abbott RJ. James JK, et al. Evolution. 2005 Dec;59(12):2533-47. Evolution. 2005. PMID: 16526502
Here we present evidence for the recent origin (within the past 300 years) of a new homoploid hybrid species, Senecio squalidus (Asteraceae), in the British Isles, following long-distance dispersal of hybrid material from a hybrid zone between S. aethnensis and S. c …
