Water deficiency compromises plant performance and yield in many habitats and in
agriculture. In addition to survival of the acute drought stress period which depends on plant …

At a whole plant level the effects of drought is usually perceived as a decrease in growth and
photosynthetic carbon assimilation. That is why this review is focused mainly on recent …

Biological N2 fixation represents the major source of N input in agricultural soils including
those in arid regions. The major N2-fixing systems are the symbiotic systems, which can play …

Legumes are well recognized for their nutritional and health benefits as well as for their
impact in the sustainability of agricultural systems. The threatening scenario imposed by …

Members of the plant family Leguminosae (Fabaceae) are unique in that they have evolved
a symbiotic relationship with rhizobia (a group of soil bacteria that can fix atmospheric …

In this paper we review both the methods for estimating N2 fixation and the quantity of N2
fixed by annual crop legumes. Available data on the N difference method for estimating N2 …

In natural and agroecosystems, plants are continuously exposed to several environmental
stress factors. Besides having evolved several indigenous tolerance mechanisms, proper …

Despite its relevance, protein regulation, metabolic adjustment, and the physiological status
of plants under drought is not well understood in relation to the role of nitrogen fixation in …

ABSTRACTDrought stress, one of the most common environmental limitations affecting
growth and productivity of plants, causes many metabolic, mechanic and oxidative changes …

A greenhouse experiment was conducted to assess the effect of water stress on growth and
metabolic changes in nodules and other plant parts of two leguminous species, Phaseolus …
