|a Carbohydrate metabolism and symbiont survival were studied in nodules of soybean (G. max [L.] Merr. cv. Maple Arrow infected with Bradyrhizobium japonicum 61-A-101), induced to senesce simultaneously by application of the photosynthesis inhibitor dichloromethyl urea (DCMU). The plant-borne carbohydrates sucrose and starch started to decline after 2 d and reached background levels after 8 d, in parallel with the decline of nitrogenase. However, the microsymbiont-borne disaccharide trehalose declined only by about 40% and subsequently remained at a constant level of c. 6 mg x g(-1) dry weight up to 14 d, when nodules softened and decayed. The number of re-isolated viable bacteria was not significantly decreased in senescent nodules as compared to control nodules. These results indicate that during terminal senescence of nodules an appreciable part of the bacteria conserve their trehalose pools and survive
