INVASIVE NEUTERING. "Long-distance dispersal of only one mating type to a region, especially in invasive species, may disable sexual systems, resulting in sterility." http://www.pnas.org/content/112/29/8859.full View in LinkedIn

SEEDS AND STERILITY. "Very low seed production and even complete sterility are common features of clonal plant populations. Sterility can be caused by a variety of environmental and genetic factors influencing various stages in the process of sexual reproduction." http://www.pnas.org/content/112/29/8859.full View in LinkedIn

SEX RATIOS. Populations usually strive to generate equal numbers of each sex, but extreme deviations from this condition do occur quite frequently. Read this fascinating article about these deviations from the assumed norm. https://lnkd.in/e2CjiWF View in LinkedIn

IMPACT. "The widespread occurrence in dioecious species of both sexual and clonal reproduction provides an opportunity to investigate how these two reproductive modes interact to influence sex ratios and fitness in plant populations." http://www.pnas.org/content/112/29/8859.full View in LinkedIn

LABILE AND UNCONSTRAINED. "The occurrence of different mechanisms of clonal reproduction among related species suggests that clonal strategies are relatively labile and that their evolution is not strongly constrained." http://www.pnas.org/content/112/29/8859.full View in LinkedIn

FREQUENCY. “There are 15 600 dioecious angiosperms in 987 genera and 175 families, or 5–6% of the total species (7% of genera, 43% of families), with somewhere between 871 to 5000 independent origins of dioecy. Some 43% of all dioecious angiosperms are in just 34 entirely dioecious clades, arguing against a consistent negative influence of dioecy on diversification.” https://lnkd.in/dUmPa47 View in LinkedIn

IN PROCESS. "Although it has a complex inheritance, genes controlling apomictic reproduction are being identified. Transfer of apomixis to crop species through wide crosses has not been successful so far, but transgenic technology offers a more powerful way to introgress apomixis into crop species." https://lnkd.in/dTm5T5f View in LinkedIn

"APOMIXIS is the clonal production of a plant through seed. It is a naturally occurring trait that has been studied for many years but the tools necessary to dissect it at the molecular level have been available only recently." https://lnkd.in/dXcGB3t View in LinkedIn

DATA SUPPLIED. "Here, we show that the phenotypes of Hieracium pilosella hybrids can be fixed across generations by apomixis." http://www.sciencedirect.com/science/article/pii/S0960982215015766 View in LinkedIn

TO BE DETERMINED. "Phenotypic plasticity may not be the only mechanism enabling clonal invaders to colonize widely, and the role of somatic mutations and epigenetic variation would be worth investigating in the future." http://www.pnas.org/content/112/29/8859.full View in LinkedIn
