Abstract

SUMMARY: The nodules of yellow lupin plants ( L.) increased logarithmically in wet weight, leghaemoglobin and rhizobial numbers. Bacteroids were isolated from such nodules and the changes in concentration of protein, RNA and DNA per organism were followed as a function of nodule age. Six weeks after emergence, DNA and RNA per organism had fallen to 40% and 13%, respectively, of the values found in the bacteria from 1-week-old nodules. No further changes in RNA and DNA were found after this time. The decreases are discussed with reference to previous reports of loss of nuclear material during bacteroid formation.
