Source – Bioengineer.org Discovery of Early Protein Evolution Scientists from the U.S. Department of Energy’s Brookhaven National Laboratory have discovered that a crucial protein for lignin synthesis in plants evolved much earlier than previously believed. This research delved into the origins and evolution of the biochemical processes that create lignin, a vital component of plant cell walls with significant implications for the clean energy sector. When the first land plants emerged from aquatic environments, they needed to adapt for survival. According to Chang-Jun Liu, a senior scientist in Brookhaven’s Biology Department, the development of lignin was a pivotal evolutionary event, providing structural support crucial for terrestrial plant survival. Understanding how plants developed these protective mechanisms is essential as they face challenges from climate change. Lignin, a tough plant material, can be processed into valuable bioproducts and serves as the only renewable sourc...
