Portions of this topic have been included in other recent reviews (McDermott et al. 1989; Day, Copeland 1991; Streeter 1991; Gordon 1992). In general, the literature cited here has been limited to papers not cited in those reviews. All of these earlier reviews contain schemes that illustrate processes of transport and metabolism in nodules; although these are very useful in providing a framework for understanding nodule function, they are not reproduced here because of space constraints. Because function is often related to the structure of nodules, the recent summary of nodule anatomy by Brown and Walsh (1994) is also noteworthy. In this report the structure of nodules from 43 species in 31 different genera of legumes is documented in a tabular summary of features and in a helpful selection of micrographs. |
