General Rules for Abbreviations
In the text, authors may use, without definition, abbreviations for units of measurement and the abbreviations in this list. Other abbreviations should be written out the first time and abbreviated thereafter. For example, "Leaf xylem pressure potentials (XPP) were measured. . ." In the title and abstract, words should be spelled out, except for common abbreviations such as DNA.
