==Description==
Line 37 ⟶ 39:
==Distribution==
It can be found growing in a variety of habitats including woodlands,
It is a constituent of wet habitats such as marshy grasslands. Some of its species{{Clarify|date=December 2023|reason=The article is about a species, not a genus}}have adapted to contaminated conditions and can cope with heavy metals. It can exist up to {{convert|2500|ft}}.<ref>{{cite book |author =C. E. Hubbard |author-link =Charles Edward Hubbard |year=1978 |title=Grasses |publisher=[[Penguin Books]] |isbn=9780140132274}}</ref>
==Cultivation==
It is the most commonly used species of ''[[Agrostis]]''.<ref>{{cite web|url=http://delta-intkey.com/grass/www/agrostis.htm |title=The grass genera of the world: descriptions, illustrations, identification, and information retrieval; including synonyms, morphology, anatomy, physiology, phytochemistry, cytology, classification, pathogens, world and local distribution, and references |
It is used for [[lawn|turf]] in gardens and landscapes, particularly on golf courses.<ref name= feis/> Many of the putting greens as well as an increasing number of fairways in the northern USA are creeping bentgrass.
==Transgenic varieties==
Early work in creeping bentgrass transgenics looked at glyphosate-resistance. However, due to easy wind pollination, seeds were dispersed into the environment. A 2004 gene flow study (with scientific sampling methods) documents gene flow on a landscape level, with a maximum at {{convert|21|km}} and {{convert|14|km|abbr=on}} (respectively) in ''sentinel'' and ''resident plants'' observed by scientist, located in primarily nonagronomic places such as irrigation ditches.<ref name=AStolonifPollens2004>{{cite journal|author=Lidia S.

Other work in transgenic bentgrass looks into salinity tolerance. The improved performance of the transgenic plants was associated with higher relative water content, higher sodium uptake and lower solute leakage in leaf tissues, with higher concentrations of Na+, K+, Cl- and total phosphorus in root tissues, and with higher auxin accumulation rate in the root tissue. This transgenic plant can survive in the presence of 1.7% sodium chloride (half seawater salinity concentration), while the non transgenic line and wild type plants cannot.<ref>ZHIGANG LI, Christian M.
