Species interactions and plant polyploidy.
Polyploidy is a common mode of speciation that can have far-reaching consequences for plant ecology and evolution. Because polyploidy can induce an array of phenotypic changes, there can be cascading effects on interactions with other species. These interactions, in turn, can have reciprocal effects on polyploid plants, potentially impacting their establishment and persistence. Although there i...
متن کاملPlant polyploidy and insect/plant interactions.
We used flow cytometry and extensive geographic surveys of herbivore attack to test whether repeated evolution of autotetraploidy in the perennial herb Heuchera grossulariifolia Rydb. (Saxifragaceae) has created evolutionary barriers to attack by the specialist moth herbivore Greya politella (Prodoxidae). We found that the moth has colonized tetraploid as well as diploid populations, has coloni...
متن کاملPlant polyploidy and the evolutionary ecology of plant/animal interactions
Until recently almost nothing was known about the effects of plant polyploidy on interactions with herbivores and pollinators. Studies of the saxifrage Heuchera grossulariifolia throughout its geographical range in the US northern Rockies have shown that autopolyploidy has probably arisen multiple times within this species since the end of the Pleistocene. Tetraploids from those different origi...
متن کاملPolyploidy: From Evolution to New Plant Development Polyploidy: From Evolution to New Plant Development©
INTRODUCTION Polyploidy is an intriguing phenomenon in plants that has provided an important pathway for evolution and speciation. Although the first polyploid was discovered over a century ago, the genetic and evolutionary implications of polyploidy are still being elucidated (Bennett, 2004; Soltis et al., 2003). On a more practical level, there are many opportunities for utilizing polyploidy ...
متن کاملInteractions among plant species and microorganisms in salt marsh sediments.
The interactions among Spartina patens and sediment microbial populations and the interactions among Phragmites australis and sediment microbial populations were studied at monotypic sites in Piermont Marsh, a salt marsh of the Hudson River north of New York, N.Y., at key times during the growing season. Arbuscular mycorrhizal fungi (AMF) effectively colonized S. patens but not P. australis, an...
