Abstract
When nitrogen fixing legumes are subjected to drought, it is not obvious which function of the stressed plant is actually affecting the nodule. There is a direct correlation between the decreased nodule water potential and the decline of nitrogenase activity (Pankhurst, Sprent, 1975). Recently, the idea that metabolic potential of nodules is reduced during drought has been confirmed (Diaz del Castillo et al., 1994). We have suggested a key role for sucrose synthase in nodules of soybean subjected to drought (González et al., 1995). Our results suggest that this observation can be also assumed for temperate legumes with indeterminate nodules.
