P.17 left column: "The current prosperous biosphere that exists on land started with colonization of the land by early plants in the mid-Paleozoic era, between ~480 and 360 million years ago. After early diversification, these land plants developed long-distance transport systems for efficient conduction of water and carbohydrates. The constituent elements of these systems are water-conducting cells (WCCs), which conduct water and nutrients, and food-conducting cells (FCCs), which conduct carbohydrates and amino acids (Ligrone et al., 2012, Lucas et al., 2013, Raven, 2003, van Bel, 2003)." |
