“…The concentration and purity of DNA extracts were measured with a NanoDrop OD2000C (Thermo Electron Corporation, USA). Since recA gene has been evidenced as an excellent molecular marker for differentiating haplotypes in rhizobial populations (Vinuesa et al 2005), and its sequence analysis has been widely used alone (Li et al 2022) or together with other housekeeping genes (Sijilmassi et al 2021) to screen the species a liation of rhizobial strains, recA sequence analysis was performed at rst to grouping the isolates into haplotypes (Li et al 2022). For this analysis, the DNA extract was used as templates for PCR ampli cation of the recA genes with the primer pair of recA41F/recA640R and the described PCR protocol (Vinuesa et al 2005).…”

As a legume crop widely cultured in the world, faba bean (Vicia faba L.) plants form root nodules with diverse Rhizobium species in different regions. But the symbionts associated with this plant in Mexico has not been studied although it has been cultured for more than 500 years in the country. To investigate the diversity and species-symbiovar affiliations of rhizobia associated with faba bean in Mexico, we isolated the rhizobia of this plant grown in Mexico. Based upon the analysis of recA gene phylogeny, two genotypes were distinguished among a total of 35 isolates, and they were identified as Rhizobium hidalgonense and Rhizobium redzepovicii, respectively, by the whole genomic sequence analysis. Both the species harbored identical nod gene cluster and the same phylogenetic positions of nodC and nifH. So, all of them were identified into the symbiovar viciae. R. hidalgonense was only isolated from slightly acid soil and R. redzepvicii was found in acid and neutral soils in this study. The community composition of rhizobia associated with faba bean in Mexico was unique since these two Rhizobium species previously reported as symbionts of common bean. As conclusion, faba bean rhizobia in Mexico formed novel symbiovar, sv. viciae, in species R. hidalgonense and R. redzepovicii. These results added novel evidence about the co-evolution, diversification and biogeographic patterns of rhizobia in association with their host legumes in distinct geographic regions.

“…To assess the competitive ability of S. obtusifolia and its sensitivity to water deficit in a controlled environment, three palatable species including Chamaecrista mimosoides L. (an annual legume), Andropogon gayanus Kunth (perennial grass) and Pennisetum pedicellatum Trin (annual grass) were used each in a mixture with S. obtusifolia in a greenhouse experiment under water deficit conditions. Chamaecrista mimosoides L. is a prostrate leguminous herb in open grasslands along roads and paths (Bargali and Bargali 2016;Li et al 2022). It is an erect annual herb up to a meter long, sometimes woody at the base with many slender, pubescent branches.…”

Assessing the competitive ability of the invader Senna obtusifolia with coexisting natives species under different water stress regimes

Invasive species tend to pose a threat to ecosystem biodiversity, functioning, and ecosystem service provision. This study was conducted in Burkina Faso to assess the competitiveness of an invasive species Senna obtusifolia that is a less palatable legume plant in West African Sahelian rangelands. To address the research hypothesis that the recurrent drought in the Sahel results in S. obtusifolia being more competitive in the land invasion, we conducted an interspecific competition involving S. obtusifolia and 3 herbaceous species (Andropogon gayanus, Chamaecrista mimosoides, and Pennisetum pedicellatum) in a greenhouse experiment under four water stress regimes using a replacement series design. The height and biomass of each species were measured throughout four months experiment. In the severe water regime, S. obtusifolia was the most sensitive to water deficit while the 3 other species were found to be resistant. In addition, in all water regimes, the aggressivity index revealed that S. obtusifolia was less competitive than the grass species A. gayanus and P. pedicellatum. Further, the study discovered that drought in the Sahel made S. obtusifolia more vulnerable than the other species. Hence the invasion of Sahelian rangelands by S. obtusifolia could be favored by overgrazing that reduces fodder species' dominance and competitiveness. Good management of sahelian rangelands by controlling grazing could help to reduce S. obtusifolia invasion and provide more fodder for livestock.
