Inbreeding is also used to reveal deleterious recessive alleles, which can then be eliminated through assortative breeding or through culling. In plant breeding, inbred lines are used as stocks for the creation of hybrid lines to make use of the effects of heterosis. Inbreeding in plants also occurs naturally in the form of self-pollination.
Their model predicted that most plants would either be outcrossing or selfing. [12] The observation of large numbers of species with mixed mating contradicted this idea, and motivated others to develop models to explain the prevalence of mixed mating systems including ideas such as selective interference and pollen discounting.

Crown gall disease caused by Agrobacterium. Most bacteria associated with plants are saprotrophic and do no harm to the plant itself. However, a small number, around 100 known species, cause disease, especially in subtropical and tropical regions of the world. [15] [page needed] Most plant pathogenic bacteria are bacilli.
Plant disease triangle. Epidemiology is the study of factors affecting the outbreak and spread of infectious diseases. [10] A disease triangle describes the basic factors required for plant diseases. These are the host plant, the pathogen, and the environment. Any one of these can be modified to control a disease. [11]

Thus outbred strains of most laboratory animals are also available, where an outbred strain is a strain of an organism that is effectively wildtype in nature, where there is as little inbreeding as possible. [2] Certain plants including the genetic model organism Arabidopsis thaliana naturally self-pollinate, which makes it quite easy to create ...
Close inbreeding reduces fitness through inbreeding depression, but some inbreeding brings benefits. [19] [20] Indeed, inbreeding "increases the speed of selection of beneficial recessive and co-dominant alleles, e.g. those that protect against diseases." [21]
