Can obligate apomixis and more stable reproductive assurance explain the distributional successes of asexual triploids in Hieracium alpinum (Asteraceae)?
Mráz P, Zdvořák P, Hartmann M, Štefánek M, Chrtek J. Mráz P, et al. Plant Biol (Stuttg). 2019 Mar;21(2):227-236. doi: 10.1111/plb.12930. Epub 2018 Dec 11. Plant Biol (Stuttg). 2019. PMID: 30369009
We assessed the level of sexual versus apomictic reproduction in diploid and triploid plants of Hieracium alpinum across its distributional range using flow cytometric analyses of seeds, and compared the level of potential and realized seed set, i.e. reproductive as …

Integument cell gelatinisation-the fate of the integumentary cells in Hieracium and Pilosella (Asteraceae).
Płachno BJ, Świątek P, Kozieradzka-Kiszkurno M, Szeląg Z, Stolarczyk P. Płachno BJ, et al. Protoplasma. 2017 Nov;254(6):2287-2294. doi: 10.1007/s00709-017-1120-1. Epub 2017 May 15. Protoplasma. 2017. PMID: 28508157 Free PMC article.
Members of the genera Hieracium and Pilosella are model plants that are used to study the mechanisms of apomixis. ...The main aim of our paper was to investigate the changes in the integument cells at the ultrastructural level in Pilosella officinarum and Hieracium …

Greater reproductive assurance of asexual plant compared with sexual relative in a low-density sympatric population: Experimental evidence for pollen limitation.
Mráz P, Mrázová V. Mráz P, et al. J Evol Biol. 2021 Sep;34(9):1503-1509. doi: 10.1111/jeb.13910. Epub 2021 Aug 12. J Evol Biol. 2021. PMID: 34331325 Free article.
Here, we compared the level and stability of reproductive assurance between sexual self-incompatible and asexual autonomously apomictic plants of Hieracium alpinum (Asteraceae) cultivated in a sympatric low-density population with two levels of spatial clumping of s …
