A full-length cDNA clone encoding cytosolic glutamine synthetase (GS), expressed in roots and root nodules of soybean, was isolated by direct complementation of an Escherichia coli gln A- mutant. This sequence is induced in roots by the availability of ammonia. A 3.5-kilobase promoter fragment of a genomic clone (lambda GS15) corresponding to this cDNA was isolated and fused with a reporter [be...

The objective of this research was to identify the existence root exudation organic acid in Lotus corniculatus germplasms subjected toxic aluminum (Al) levels and investigate effect mechanism on Al content tissue morphological parameters plant development. Two experiments were performed nutrient solution evaluate accumulation acids, using cultivars INIA Draco São Gabriel genotypes UFRGS UF-T2. ...

Strain S658(T) was isolated from a Lotus corniculatus nodule in a soil sample obtained in Uruguay. Phylogenetic analysis of the 16S rRNA gene and atpD gene showed that this strain clustered within the genus Phyllobacterium. The closest related species was, in both cases, Phyllobacterium trifolii PETP02(T) with 99.8 % sequence similarity in the 16S rRNA gene and 96.1 % in the atpD gene. The 16S ...

The aim of this study was to determine the nutritive value of some legume species in salt-affected soils of South-East Anatolian region using chemical composition and in vitro gas production kinetics. In this study, Lotus corniculatus, Trifolium alexandrinum, Medicago sativa were sown and tested in four different locations. A 3 by 4 factorial design with 3 legume species and 4 salt levels (non ...
