Editing Root (section)

===Definition===
In its simplest form, the term root system architecture (RSA) refers to the spatial configuration of a plant's root system. This system can be extremely complex and is dependent upon multiple factors such as the species of the plant itself, the composition of the soil and the availability of nutrients.<ref>{{cite journal| vauthors = Malamy JE |title=Intrinsic and environmental response pathways that regulate root system architecture |journal=Plant, Cell & Environment |year=2005|volume=28|issue=1 |pages=67–77 |doi=10.1111/j.1365-3040.2005.01306.x|pmid=16021787 |doi-access=free |bibcode=2005PCEnv..28...67M }}</ref> Root architecture plays the important role of providing a secure supply of nutrients and water as well as anchorage and support.

The configuration of root systems serves to structurally support the plant, compete with other plants and for uptake of nutrients from the soil.<ref name=":0">{{cite journal | vauthors = Caldwell MM, Dawson TE, Richards JH | title = Hydraulic lift: consequences of water efflux from the roots of plants | journal = Oecologia | volume = 113 | issue = 2 | pages = 151–161 | date = January 1998 | pmid = 28308192 | doi = 10.1007/s004420050363 | bibcode = 1998Oecol.113..151C }}</ref> Roots grow to specific conditions, which, if changed, can impede a plant's growth. For example, a root system that has developed in dry soil may not be as efficient in flooded soil, yet plants are able to adapt to other changes in the environment, such as seasonal changes.<ref name=":0" />
