“…Most species of this family, more than 750 species, belong to the genus Silene. [18][19][20] Silene (Caryophyllaceae) is a blooming plant that is mainly spread out in Africa, North America and Eurasia. 18 For both pharmacological and ethnomedicinal studies, Silene is one of the most extensively investigated genera in the Caryophellaceae family.…”

The role of hybrid seed inviability in angiosperm speciation

Understanding which reproductive barriers contribute to speciation is essential to understanding the diversity of life on earth. Several contemporary examples of strong hybrid seed inviability (HSI) between recently diverged species suggest that HSI may play a fundamental role in plant speciation. Yet, a broader synthesis of HSI is needed to clarify its role in diversification. Here, I review the incidence and evolution of HSI. HSI is common and evolves rapidly, suggesting that it may play an important role early in speciation. The developmental mechanisms that underlie HSI involve similar developmental trajectories in endosperm, even between evolutionarily deeply diverged incidents of HSI. HSI is often accompanied by whole-scale gene misexpression in hybrid endosperm, including misexpression of imprinted genes which have a key role in endosperm development. I explore how an evolutionary perspective can clarify the repeated and rapid evolution of HSI. In particular, I evaluate the evidence for conflict between maternal and paternal interests in resource allocation to offspring (i.e. parental conflict). I highlight that parental conflict theory generates explicit predictions regarding the expected hybrid phenotypes and genes responsible for HSI. While much phenotypic evidence supports a role of parental conflict in the evolution of HSI, an understanding of the underlying molecular mechanisms of this barrier is essential to test parental conflict theory. Lastly, I explore what factors may influence the strength of parental conflict in natural plant populations as an explanation for why rates of HSI may differ between plant groups and the consequences of strong HSI in secondary contact.

“…Silene L., which has been an ecologically important plant group since ancient times, is a member of the Caryophyllaceae family (Ferreira et al, 2015). Silene L., one of the largest genera in the world flora, contains approximately 870 plant species (Eggens et al, 2020;Guner et al, 2012;Jafari et al, 2020;Moiloa et al, 2021).…”

Silene compacta Fisch. ex Hornem., which grows naturally, is a plant species with high ornamental plant potential in the Silene L. genus of the Caryophyllaceae family. Vegetative propagation is one of the important ways to preserve naturally growing and cultivated plant species. In this study, the effect of two different cutting areas of the cutting base (above the node-below the node) and five different indole-3-butyric acid (IBA) doses (control, 500, 1000, 2000 and 4000 ppm) on the rooting of stem cuttings taken from individuals of the natural S. compacta species were investigated. IBA was applied to the cuttings’ bases in a commercial rooting powder. Perlite+peat mixture at a ratio of 1:1 (v/v) was used in the rooting medium. Survival rate, rooting percentage, blooming rate, root number, root length, seedling height, seedling stem diameter, side shoot number, shoot length and shoot stem diameter were evaluated. The evaluation was made one month after the start of the experiment. As a result, the highest survival rate in cuttings was obtained from above-node control group (100%) and under-node 2000 ppm IBA (95%) application, and the highest rooting percentage was obtained from under-node 2000 ppm IBA (68%) and above-node control group (65%), respectively. Based on the results, it can be concluded that different cuttings of the cutting base and IBA concentrations have different effects on the rooting success of the S. compacta species with stem cuttings.
