==Host location==
A report published in ''Science'' in 2006 demonstrated that dodder use airborne [[volatile organic compound]] cues to locate their host plants. Seedlings of ''[[Cuscuta pentagona|C. pentagona]]'' exhibit positive growth responses to volatiles released by tomato and other species of host plants. When given a choice between volatiles released by the preferred host tomato and the non-host wheat, the parasite grew toward the former. Further experiments demonstrated attraction to a number of individual compounds released by host plants and repellence by one compound released by wheat. These results do not rule out the possibility that other cues, such as light, may also play a role in host location.<ref name="Parasitic Weed Seems to Smell Its Prey">{{cite news|url=http://www.physorg.com/news78763233.html|archive-url=https://archive.today/20130131061946/http://www.physorg.com/news78763233.html|url-status=dead|archive-date=2013-01-31|title=Parasitic Weed Seems to Smell Its Prey|access-date=2010-06-22|agency=Associated Press|year=2006}}</ref><ref>{{cite web|url=http://content.yudu.com/Library/A1og25/PlantsADifferentPers/resources/73.htm |title=Plants: A Different Perspective |publisher=Content.yudu.com |access-date=2012-11-17}}</ref>
