Evolution by individuals, plant-herbivore interactions, and mosaics of genetic variability: The adaptive significance of somatic mutations in plants

Abstract: Differences in the pattern of organization of organisms may lead to different patterns of evolution, genetics and ecology, Plants and animals differ in their fundamental patterns of organization. Plants consist of a series of repeating units that compete with one another, while animals consist of mutually interdependent systems that cannot compete. As a result, plants may be able to take advantage of somatic mutations in ways that are not available to animals. Somatic mutations arising in plants can be inherit… Show more

“…The occurrence of this variation is in itself interesting as it attests to the potential of C. novaezelandiae clones to accumulate genetic variation that is independent of any sexual or psuedo-sexual process. Mutational divergence of clones has been reported for a variety of clonal organisms (Suomalainen et a!., 1976;Whitham & Slobodchikoff, 1981;Stoddart, 1983a;Hughes, 1989). Such divergence can be of adaptive significance (Whitman & Sbbodchikoff, 1981;Hughes, 1989).…”

“…There is evidence for the occurrence of somatic mutations in plants (Whitham and Slobodchikoff, 1981;Antolin and Strobeck, 1985;Schaal, 1987;Klekowski, 1988;Gill et al, 1995;Kovalchuk et al, 2000b). Withinindividual variation for polygenic and cytogenetic traits has been documented by several authors (Lewis et al, 1971;Klekowski, 1988;Klekowski and Godfrey, 1989).…”

“…If errors of DNA replication accompany mitosis and are not selectively removed during vegetative growth of the plant (eg, by cell lineage sorting), they can be passed on to the gametes (Klekowski, 1988). It has been argued that somatic mutation may play an important role in producing adaptive variability among plant shoots (Whitham and Slobodchikoff, 1981;Antolin and Strobeck, 1985;Walbot, 1996), in allele frequency change within populations (Orive, 2001), and in life-history patterns of inbreeding depression and mating system evolution (Morgan, 2001). If somatic mutations are passed on to gametes this may result in genomic mutation rates that are higher in plants than in animals, especially in long-lived plants where there may be many somatic cell divisions prior to gamete production (Klekowski and Godfrey, 1989).…”

“…In general there are two views concerning the importance of somatic mutation in long-lived plants. One view stresses the positive aspects of mutation in the formation of plants that are chimeras where portions of such plants, because of their new genotypes, may have enhanced survivorship in variable biotic or abiotic environments (Whitham and Slobodchikoff, 1981;Buss, 1983;Gill and Halverson, 1984;Silander, 1985). The other view, while noting that occasional adaptive somatic mutations may occur, emphasizes mutational load and the negative aspects of genotype deterioration as the most important consequences of somatic mutation in long-lived plants (Klekowski, in press;Klekowski, 1988).…”
