This list of systems of plant taxonomy presents taxonomic systems used in plant classification. A wiktionary taxonomic system taxonomic system is a coherent whole of alpha taxonomy taxonomic judgments on circumscription taxonomy circumscription and placement of the considered taxa. It is only a system if it is applied to a large group of such taxa for example, all the flowering plants . There are two main criteria for this list. A system must be alpha taxonomy taxonomic , that is deal with a large number of plants, by their botanical name s. Secondly it must be a system, i.e. deal with the relationships of plants. Although thinking about relationships of plants had started much earlier see history of plant systematics , such systems really only came into being in the 19th century, as a result of an ever increasing influx from all over the world of newly discovered plant species. The 18th century saw some early systems, which are perhaps precursors rather than full taxonomic systems. A milestone event was the publication of Species Plantarum by Carolus Linnaeus Linnaeus which serves as the starting point of binomial nomenclature for plants. By its size this would qualify to be on this list, but it does not deal with relationships, beyond assigning plants into genera.

Genetic structure refers to any pattern in the genetics genetic makeup of individuals within a population. In the absence of genetic structure, one can infer little to nothing about the genetic makeup of an individual by studying other members of the population. When genetic structure is present, on the other hand, much can be inferred. In trivial terms, all populations have genetic structure, because all populations can be characterised by their genotype or allele frequencies if only 1 of a large sample of moths drawn from a single population have spotted wings, then it is safe to assume that any unknown individual is unlikely to have spotted wings. A more complicated example arises in dense thicket s of plants, where plants tend to be pollination pollinated by near neighbours, and seed s tend to fall and germination germinate near the maternal plant. In such a scenario, plants tend to be more closely related to nearby plants than they are to distant plants and yet they are more likely to breed with nearby plants than they are with distant plants. Thus an inbreeding cycle is created that perpetuates the pattern of plants being closely related to near neighbours. This is a form of genetic structure because one can infer much about the genetic makeup of any individual plant simply by studying plants in its immediately neighbourhood.

Mutant alleles that are not tagged for rapid cloning are Genetic screen Mapping mutants mapped and cloned by positional cloning .

Genetic redundancy is a term typically used to describe situations where a given biochemical function is redundantly encoded by two or more gene s. In these cases, mutation s or defects in one of these genes will have a smaller effect on the fitness of the organism than expected from the genes function. Characteristic examples of genetic redundancy include Enns, Kanaoka et al. 2005 and Pearce, Senis et al. 2004 . Many more examples are thoroughly discussed in Kafri, Levy & Pilpel. 2006 . The main source of genetic redundancy is the process of gene duplication which generates multiplicity in gene copy number. A second and less frequent source of genetic redundancy are convergent evolution ary processes leading to genes that are close in function but unrelated in sequence Galperin, Walker & Koonin 1998 . Genetic redundancy has classically aroused much debate in the context of evolutionary biology Nowak et al., 1997 Kafri, Springer & Pilpel . 2009 . From an evolutionary standpoint, genes with overlapping functions implies minimal, if any, selective pressure s acting on these genes. One therefore expects that the genes participating in such buffering of mutations will be subject to severe mutational drift diverging their functions and or expression patterns with considerably high rates. Indeed it has been shown that the functional divergence of paralogous pairs in both yeast and human is an extremely rapid process. Taking these notions into account, the very existence of genetic buffering ... concepts.

Smaller genetic distances indicate a close genetic relationship whereas large genetic distances indicate a more distant genetic relationship.

Refimprove date December 2009 Genetic representation is a way of representing solutions individuals in evolutionary computation methods. Genetic representation can encode appearance, behavior, physical qualities of individuals. Designing a good genetic representation that is expressive and evolvable is a hard problem in evolutionary computation. Difference in genetic representations is one of the major criteria drawing a line between known classes of evolutionary computation. Genetic algorithm s use linear binary representations. The most standard one is an array of bit s. Arrays of other types and structures can be used in essentially the same way. The main property that makes these genetic representations convenient is that their parts are easily aligned due to their fixed size. This facilitates simple crossover operation. Variable length representations were also explored in Genetic algorithm s, but crossover implementation is more complex in this case. Evolution strategy uses linear real valued representations, e.g. an array of real values. It uses mostly gaussian mutation and blending averaging crossover. Genetic programming GP pioneered tree like representations and developed genetic operator s suitable for such representations. Tree like representations are used in GP to represent and evolve functional programs with desired properties. ref http www.sover.net nichael nlc publications icga85 index.html Cramer, 1985 ref Human based genetic algorithm HBGA offers a way to avoid solving hard representation problems by outsourcing all genetic operators to outside agents, in this case, humans.
