Vicariance patterns in the Mediterranean Sea: east–west cleavage and low dispersal in the endemic seagrass Posidonia oceanica (2007, background): “Detection of individuality in clonal plants can be biased by somatic mutations (Klekowski, 1997, 2003), particularly when individuals are longlived, as in the case of P. oceanica where clones date back millennia (Marbà & Duarte, 1998; Hemminga & Duarte, 2000).”
Bud banks and their role in vegetative regeneration – A literature review and proposal for simple classification and assessment (2007, background): “In contrast, all buds developed on a plant are almost always genetically uniform (with the exception of periclinal chimeras and somatic mutants; see Klekowski, 2003), but they may differ in other characteristics.”
Rapid changes in clonal lines: the death of a 'sacred cow' (2003, background): “…generation, sometimes up to 10-2, whilst even the control region of insect mitochondrial DNA can mutate at around 10-4 per gene per generation (Lushai, Loxdale & Maclean, 2000 and Lushai & Loxdale, 2002 discuss mutation rates in a variety of living organisms; see also Klekowski, 2003, this issue).”
Death without sex—the ‘problem of the small’ and selection for reproductive economy in flowering plants (2008, background): “In this way then, a major fitness advantage through extended longevity is conferred regardless of whether the entire zygote product (clone or genet) eventually expires due to ‘mutational meltdown’ (Klekowski 2003).”
Standardizing methods to address clonality in population studies (2007, background): “Indeed, the assignment of genetic identity of clones has recently been questioned (Klekowski 2003).”
The Patterns and Causes of Variation in Plant Nucleotide Substitution Rates (2011, background): “For example, broadly expressed genes must function in different biochemical environments; therefore, they may be able to tolerate fewer mutations (Kuma et al. 1995, Duret & Mouchiroud 2000).”
The Evolutionary Maintenance of Sexual Reproduction: Evidence from the Ecological Distribution of Asexual Reproduction in Clonal Plants (2008, background): “A source of bias that could inflate G/N and other estimates of clonal diversity is somatic mutation (Klekowski 2003).”
