- Title
Plant Evolution Timeline.
- Abstract
The article reports that scientists at the University of British Columbia and Standford University have found lignin in marine algae. Lead scientists Patrick Martone and colleagues used powerful chemical and microscopic anatomy techniques to identify and localize lignin within cell walls of a red algae. According to Martone, lignin evolved after plants took to land as a mechanical adaptation for stabilizing upright growth and transporting water from the root. Thus, the finding provides a news perspective on the early evolution of lignified support tissues.
