Plants require an internal conducting network to transport food and water around their bodies. This conducting network is termed vasculature and consists of two tissues; water conducting xylem and food conducting phloem. The acquisition of these tissues during plant evolution was key for the origin of trees and crops from tiny moss-like ancestors. Despite the importance of the phloem for transporting sugars as well as a diversity of other compounds and signalling molecules throughout plants we know almost nothing about its evolution or how it responds to climate change. The aim for this project is to study the evolution of the phloem over its 400 million year history and to answer key evolution questions such as: (i) when did the phloem originate, (ii) how has its structure, function and genetic toolkit evolved over the past 400 million years, (iii) how has phloem evolution been driven by climate change?

植物需要一个内部的传导网络在它们的身体周围输送食物和水。这个传导网络被称为脉管系统，由两个组织组成；水传导木质部，食物传导韧皮部。在植物进化过程中获得这些组织是树木和作物从微小的苔藓状祖先起源的关键。尽管韧皮部在整个植物中运输糖以及各种其他化合物和信号分子方面很重要，但我们对它的进化或它对气候变化的反应几乎一无所知。该项目的目的是研究韧皮部在其4亿年历史中的进化，并回答关键的进化问题，如：(i)韧皮部何时起源；（ii）在过去4亿年中，韧皮部的结构、功能和遗传工具是如何进化的；（iii）韧皮部的进化是如何受到气候变化的驱动的？
