Chickpea rhizobia symbiosis genes are highly conserved across multiple Mesorhiz...
Laranjo, Marta; Alexandre, Ana; Rivas, Raul; Velázquez, Encarna; Young, J. Peter W.; Oliveira, SolangeABSTRACT Chickpea has been considered as a restrictive host for nodulation by rhizobia. However, recent studies have reported that several Mesorhizobium species may effectively nodulate chickpea. With the purpose of investigating the evolutionary relationships between these different species with the ability of nodulating the same host, we analysed 21 Portuguese chickpea rhizobial isolates. Symbiosis genes nifH...
Strains of Mesorhizobium amorphae and M. tianshanense carrying symbiotic genes ...
Rivas, Raul; Laranjo, Marta; Mateos, Pedro; Oliveira, Solange; Martínez-Molina, Eustoquio; Velázquez, EncarnaAims: To identify several strains of Mesorhizobium amorphae and Mesorhizobium tianshanense nodulating Cicer arietinum in Spain and Portugal, and to study the symbiotic genes carried by these strains. Methods and Results: The sequences of 16S-23S intergenic spacer (ITS), 16S rRNA gene and symbiotic genes nodC and nifH were analysed. According to their 16S rRNA gene and ITS sequences, the strains from this study ...
