“…4) suggesting that P deficiency indirectly affects subsequent nodule development by restricting metabolite supply from the host plant (Tang et aI., 2001). Thus the exploration of genotypic variability in the responses of the common-bean to P deficiency may allow identification of physiological or biochemical tools for screening tolerant varieties and enable the productivity of this crop to be improved (Krouma et al, 2006). In conclusion, this study identifies the promising accessions PHA-0014, PHA-0053, PHA-0098, PHA-OI87, PHA-0273, PHA-0331, and PMB-0002, which can be used as a source of genetic diversity for breeding programs to improve P use efficiency for SNF in the common-bean.…”

Variation among common-bean accessions (Phaseolus vulgaris L.) from the Iberian Peninsula for N2-dependent growth and phosphorus requirement

et al. 2009

The common-bean often faces phosphorus deficiency in soils where it is grown. Such a deficiency is a major limitation to yield improvement, especially as the common-bean depends upon nitrogen fixation. Screening for symbiotic nitrogen fixation under phosphorus deficiency was performed with 33 common-bean accessions representing the diversity of 15 European market classes from the Iberian Peninsula. These accessions were inoculated with Rhizobium tropici CIAT899 and grown in an aerated nitrogen-free nutrient solution at deficient versus sufficient phosphorous supplies (75 vs. 250 urnol plant" week-I) in a glasshouse. A large variability in N 2-dependent growth under P deficiency was found with most tolerance to P deficiency among late type IV Andean landraces, with the exception of 3 early type I Andean landraces. From this screening four contrasting landraces were selected for their high efficiency in the use of P for their symbiotic N nutrition, and compared with the cultivar Linex in fields of a reference production area over 3 years. The landraces from the Iberian Peninsula expressed a higher growth than the cultivar Linex, although they showed a lower nodulation. We hypothesize that the identified P tolerance among Iberian Peninsula accessions may be useful for improving symbiotic nitrogen fixation in the common-bean when growth is limited by available soil-P and could contribute to sustainable farming systems by reducing farmers' dependence on fertilizers.

“…The legume-rhizobia symbiosis is particularly sensitive to Fe-deficiency (Tang et al 1991). Fe-deficiency limits root nodule bacterial survival and multiplication, as well as host plant growth (O' Hara et al 1998) because Fe involves in the development of nodules and their function (Ragland and Theil 1993;Krouma et al 2006). In particular, Fe is required for some key proteins engaged in N 2 -fixation (nitrogenase, leghemoglobin) and in nitrogen assimilation (glutamate reductase, nitrate reductase) (Vanoni and Curti 2005;Clement et al 2005).…”

Fe modulates Cd-induced oxidative stress and the expression of stress responsive proteins in the nodules of Vigna radiata

The aim of this study was to investigate the protective role of Fe in providing tolerance against Cd-stress in root nodules of Vigna radiata, because Cd may be more deleterious in the absence of Fe. Biochemical, histological and proteomic responses to Cd-exposure (50 lM CdCl 2 ) were examined under Fe-sufficient (?Fe/ ?Cd) or Fe-deficient (-Fe/?Cd) soils by comparing non -Cd exposed control (?Fe/-Cd) plants with additional control of Fe-deficient and non-exposed Cd plants (-Fe/ -Cd). Cd-exposure negatively affected on growth and some physiological parameters of host plant and nodules, and also induced oxidative stress with the decline of antioxidative enzyme activities. The negative effects of Cd-exposure in ?Fe/?Cd plants were much less than those in -Fe/?Cd and -Fe/-Cd ones. When compared with -Fe/Cd and -Fe/-Cd plants, a marked improvement of bacteriod development and cell division was observed and deformation of cell wall remarkably alleviated in the nodules of (?Fe/Cd) plants. Proteomic study revealed that 20 proteins were differentially expressed by Fe/Cd combined treatment. Eleven proteins of interest were identified and classified as precursor for RNA metabolism, storage of seeds, hypothetical proteins, and unknown proteins. These results indicate that Fe plays a pivotal role in alleviating Cd-stress, as evidence by reduction in oxidative damage and protection of cell wall and bacteriods in nodules.

“…Symbiotic nitrogen fixation (SNF) in common bean is considered to be small (Pereira and Bliss 1987) in comparison with other legumes. In some studies carried out on iron requirements of the symbiosis (Krouma and Abdelly 2003;Krouma et al 2006), Fe has received considerable attention due to the dramatic effects observed when nodulated common bean is subjected to low iron availability. This element is frequently one of the most limiting nutrients for plant growth in calcareous soils, and it is estimated that under these condition, soil solution Fe does not cover more than 0.1-10% of the plant's Fe requirement (Mortvedt 1991).…”

“…The legume-rhizobia symbiosis is particularly sensitive to Fe deficiency (Tang et al 1990). The latter can limit root nodule bacterial survival and multiplication, as well as host-plant growth, nodule initiation, development (O'Hara et al 1988;Ragland and Theil 1993) and function (Krouma et al 2006). In particular, Fe is required for some key proteins involved in nitrogen fixation like nitrogenase, nitrogenase reductase and leghaemoglobin (Moran et al 1997), and nitrogen assimilation like glutamate reductase (Vanoni and Curti 2005), nitrate reductase and nitrite reductase (Clément et al 2005).…”

A greenhouse experiment was carried out aiming to study the effect of iron deficiency on nitrogen fixation and ammonium assimilation in common bean nodules. Host-plant and nodule growth, symbiotic nitrogen fixation, glutamine synthetase (GS) and glutamate dehydrogenase (GDH) were analyzed in two common bean varieties subjected to iron deficiency. Results showed that host-plant and nodules growth, nitrogen fixation and GS activity decreased when under Fe-deficiency against an important increase of ammonium accumulation and GDH activity. Tolerant variety Flamingo is clearly less affected by iron deficiency than the sensitive one, Coco blanc. The allocation of iron to nodules and Fe use-efficiency for nodule growth and symbiotic nitrogen fixation were on the basis of the symbiotic performance of Flamingo under iron deprivation. Under Fe-deficiency, GDH take over GS the ammonium assimilation activity, particularly in the tolerant variety. Keywords Common bean . Fe use-efficiency . Glutamate dehydrogenase .
