The continuing relevance of “older” mycorrhiza literature: insights from the work of John Laker Harley (1911–1990)
To new generations of scientists beginning their careers in research, we strongly recommend the practice of reading older literature. To illustrate the value of doing so, we highlight six insights of one of the most influential mycorrhiza researchers of the twentieth century, Jack Harley. These insights concerning mycotrophy, the new niche, the sheath, C cycling, N cycling, and mutualism were published prior to 1975 and so may have escaped the notice of many, but they laid the groundwork for some of the most important research of today.
