生物学入门课程的宗旨之一是学习任何单位的形式或结构如何决定其功能，而形式和功能长期以来一直被用来理解整个自然世界的模式（Grew，1682；Wainwright，1988；D ıaz 等，2016）。形态预测植物细胞和器官水平的功能；例如，木质部细胞直径和凹坑孔径是茎木质部水力传导和栓塞脆弱性的重要指标（Pittermann＆Sperry，2005）。此外，理论处理和实验证据均表明根部水力功能与叶功能耦合（Cruiziat 等，2002；Domec 等，2009），但很少有研究调查根的解剖结构和形态如何影响叶功能。在本期《新植物学家》中，周等人。 （2021 年；第 1481-1491 页）提出了长期降水实验的结果，表明根部形态可以预测叶子的生理学。这项研究强调，一个器官的形式可以对整个生物体的功能产生影响，为研究形式与功能关系提供了独特的视角。
One of the tenets of introductory biology courses is learning how the form or structure of any unit determines its function, and that form and function has long been used to understand patterns throughout the natural world (Grew, 1682; Wainwright, 1988; D ıaz et al., 2016). Form predicts function at the cellular and organ level in plants; for instance, xylem cell diameter and pit pore size are great indicators of stem xylem hydraulic conductance and vulnerability to embolism (Pittermann & Sperry, 2005). Additionally, both theoretical treatments and experimental evidence indicate that root hydraulic function is coupled to leaf function (Cruiziat et al., 2002; Domec et al., 2009) but few studies have investigated how the anatomy and morphology of the roots may influence leaf function. In this issue of New Phytologist, Zhou et al. (2021; pp. 1481–1491) present results from a long-term precipitation experiment, showing that root form predicted leaf physiology. This study highlights that the form of one organ can have effects on function across the entire organism, providing a unique perspective in the study of form–function relationships.
