“…Hardarson et al (1993) and Nleya et al (2002) observed substantial variability in SNF among different types of common bean, and Miranda and Bliss (1991) concluded that most common bean landraces have low symbiotic nitrogen fixation (SNF) capacity because of their original domestication as a homegarden crop, which resulted in a low selection pressure for the symbiosis with rhizobia. The nodule proportion of root biomass in genotypes with a BNO phenotype (up to 14%) was higher than those previously reported, which ranged from 0.5 to 8% (DeJong et al 1981;Skøt 1983;Vessey 1992;Martensson and Rydberg 1996;Santalla et al 2001;Laguerre et al 2007). In both the SNO and BNO phenotypes, the relationship between nodule biomass and nodule number that should result from autoregulation of the nodule number was commonly observed.…”

Common bean symbiotic nitrogen fixation provides an ecological and economical alternative to increase bean production but it depends on soil fertility and climate conditions. The objectives of this work were to characterize common bean genotypes for their ability to establish symbiosis under controlled conditions and to study the effect of the environment on the expression of those genotypes. The experiment under controlled conditions was conducted in a greenhouse with 158 genotypes that represented the major dry bean market classes. The field experiment was carried out in six environments with 64 genotypes that were previously selected for their contrasting nodulation ability and/or root development under the controlled conditions experiment. Nodulation, plant, and grain yield data of the bean genotypes were measured in both experiments. There was a significant high variability in plant development responses among the studied genotypes associated with the rhizobial strain inoculated under controlled conditions. Two nodulation phenotypes were observed among the genotypes tested: the big-nodules phenotype (BNO) associated with almost 63% fewer nodules and 58% higher proportion of nodule biomass in the below-ground compartment than the smallnodules phenotype (SNO) with less developed aerial parts. Genotype plus genotype × environment (GGE) biplot model analysis enabled identification of the highest-yielding genotypes for the different environments. The soil chemical factors of these environments were associated with the nodule number or the biomass of the common bean genotypes. Genotypes with a BNO phenotype showed a good plant response, indicating that this phenotype may be more beneficial for plant growth and seed yield in environmental conditions that may limit nodule development. The amplitude of the genotypic variability found in this work confirms the potential for rhizobial symbiosis of adapted bean genotypes, which could constitute a preferential material for initial breeding of symbiotically active lines. The data also indicate the potential of bean breeding to identify environments containing effective strains of rhizobia essential for sustainable agriculture, improving productivity, and maintaining environmental quality.

“…Variations of shoot DM, nodule number and nodule DM with the inoculated Rhizobium strains confirm the observations by Skot (1983) and Hobbs et al (1983) on pea-rhizobia symbiosis. Bacterial partner influence on symbiosis performance was mentioned in several reports; hence, (Aouani et al 1997) grouped rhizobial strains according to their effectiveness on common bean cultivar.…”

The potential of Rhizobium strains for biological control of Orobanche crenata

Orobanche crenata Forsk is a chlorophyll lacking holoparasite that subsists on the roots of plants and causes significant damage to the culture of leguminous plants and, in particular, to peas (Pisum sativum L.). Here, we investigated the potential of Rhizobium strains for biological control of Orobanche crenata using a commercial pea cultivar (Douce de province) and different Rhizobium strains. Firstly, benefit of bacterial inoculation on plant growth and efficiency in N-incorporation were demonstrated with four isolates, P.SOM, P.1001, P.Mat.95 and P.1236. After five Rhizobium strains (three efficient: P.SOM, P.1236, P.Mat.95 and two not efficient: P.OM1.92, P.MleTem.92) were investigated for their ability to control Orobanche crenata using pot and Petri dish experiments. Inoculation of peas with two (P.SOM and P.1236) of the five strains induced a significant decrease in O. crenata seed germination and in the number of tubercles on pea roots. Furthermore, other symptoms, including the non-penetration of the germinated seeds into pea roots followed by radicle browning and death of the parasites, were observed in the presence of these inoculated pea plants. The hypothesis that roots secrete toxic compounds related to Rhizobium inoculation is discussed.

“…1) demonstrated (average of 5 experiments) that the contributions of cultivar genotypes to total variation of shoot mass and N accumulation is higher than the contributions of strain genotypes (30.8-31.6% and 13.4-14.9%, respectively). These results differ from those presented earlier by Erdman and Burton (1939) and Sk~at (1983) who demonstrated that in the 'pea -R. leguminosarum by. viceae' system the plant mass is T h e total input o f partners' genotypes into variation of N a c c u m u l a t i o n is slightly higher than into variation of plant mass, indicating again that the f o r m e r property is more suitable for assessing the symbiotic efficiency of the R. leguminosarum bv, viceae strains than the latter.…”

From an analysis of 481 Rhizobium leguminosarum bv. viceae strains with 7 pea cultivars in pot and field experiments, we demonstrated that effective strains could be isolated from a rich medium-acid grey forest soil of the Or61 area (Central region of the European part of Russia) but not from a poor acid podzolic soil of the St. Petersburg area (North-West Russia). The proportion of the isolates significantly increasing N accumulation in pea plants (10.2%) is higher than that of strains increasing the shoot dry mass (4.6%) in the pot experiments. The mean values of the increase for N accumulation (33.8%) upon inoculation are also higher than for shoot mass (27.0%) in these experiments. N accumulation in the inoculated pea plants in the pot experiments was significantly correlated with seed yield and seed N accumulation in field experiments, while for shoot dry mass these correlations were either weak or not significant. Two-factor analysis of variance demonstrated that the contribution of plant cultivars to the variation of the major symbiotic efficiency parameters is higher (30.8-31.6%) and contributions of cultivar-strain specificity is lower (5.4-8.8%) than the contributions of strain genotypes (13.4-14.9%). We identified an ineffective R. leguminosarum bv. viceae strain 50 which can be used as a tester for assessing the nodulation competitiveness of the effective strains by an indirect method (analysis of dry mass and N accumulation in pea plants inoculated with the mixture of the tested effective strains and the tester strain). The relative competitive ability (RCA) determined by this method was 75.7-82.8% for strain 52 but only 10.5-13.8% for strain 250a; this difference was confirmed by a direct method (use of the streptomycin-resistant mutants). Results of screening of the diverse collection of 53 effective R. leguminosarum bv. viceae strains by the indirect method permits us to divide them into 3 groups (32 high-competitive, 10 medium-competitive and 11 low-competitive strains) but reveals no correlation between the competitiveness and symbiotic efficiency. N accumulation in the pea shoots is demonstrated to be a much more suitable criterion than the shoot mass for selection either of the highly-effective or of highly-competitive (by the indirect estimation) R. leguminosarum by. viceae strains in the pot experiments.
