“…In these phylogenies, I. vera isolates clustered into three phylogenetic groups; some had gene sequences that resembled those previously reported from Los Tuxtlas soils [41] in South of Veracruz. Some isolates related to CCGUVB1N3 were close to BRUESC1066 from Inga ingoides isolated in Brazil [39]. Isolates related to CCGUVB23 had identical glnII and 16S rRNA sequences to TUX-10, which was close to BRUESC644 from Brazil.…”

“…Isolates related to CCGUVB23 had identical glnII and 16S rRNA sequences to TUX-10, which was close to BRUESC644 from Brazil. CCGUVB14 and CCGUVB4N were related to isolates from diverse plants as well as some others isolated from diverse Inga species, such as TUX-15, BRUESC1084 and BRUESC441 [39]. Isolate CCGB01 was close to isolate CCGB20 and TUX-7 and CCGB12 was closer to TUX-4; TUX strains were isolated from Los Tuxtlas soils in Veracruz [41].…”

“…Recently, many new Bradyrhizobium species and lineages have been described [34][35][36][37][38] and reviewed in [33]. Lysiloma isolates have not been studied, but Inga nodule bacteria from Brazil have been reported, revealing diverse symbionts [39], and Bradyrhizobium ingae was proposed for Inga laurina symbionts [40]. Previously, we studied nodule bacteria from soils with different agricultural use in Los Tuxtlas rain forest in Mexico and found several novel bradyrhizobial lineages, some capable of nodulating a native legume-tree Inga sp.…”

“…Inga plants are fast growing, improve soil fertility and tolerate acid soils. Inga is nodulated by Bradyrhizobium [39,40,48,49], especially in its main center of diversification in Brazil. It was the aim of this work to study Bradyrhizobium symbionts isolated from Lysiloma sp.…”

We identified diverse bradyrhizobia having distinct ERIC-PCR genomic fingerprints from native American trees Inga vera and Lysiloma spp. In addition, two nodule isolates recovered from Lysiloma divaricatum seedlings inoculated with soil from the tropical house of a UK botanical garden were also identified as Bradyrhizobium. Genomes were obtained (with sizes around 9 Mb each) from nine Inga and Lysiloma bradyrhizobial isolates; plasmids were detected in two of the Inga strains analyzed. Average Nucleotide Identity of whole genomes revealed five novel Bradyrhizobium genomospecies from Mexican trees, while the UK isolates were identified as Bradyrhizobium cajani and Bradyrhizobium brasilense. Inga vera and Lysiloma isolates, despite their genetic distances and different hosts, shared a common set of nod genes that suggested that I. vera and Lysiloma bradyrhizobia produce fucosylated, methylated and carbamylated lipochitooligosaccharides. Uptake hydrogenase hup, hyp and secretion system genes were found in some of the isolates. Lysiloma strains were found to be ineffective on I. vera. Some of the isolates may be used as plant inoculants.

The radiation of nodulated Chamaecrista species from the rainforest into more diverse habitats has been accompanied by a reduction in growth form and a shift from fixation threads to symbiosomes

All non-mimosoid nodulated genera in the legume subfamily Caesalpinioideae confine their rhizobial symbionts within cell wall-bound “fixation threads” (FTs). The exception is the large genus Chamaecrista in which shrubs and subshrubs house their rhizobial bacteroids more intimately within symbiosomes, whereas large trees have FTs. This study aimed to unravel the evolutionary relationships between Chamaecrista growth habit, habitat, nodule bacteroid type, and rhizobial genotype. The growth habit, bacteroid anatomy, and rhizobial symbionts of 30 nodulated Chamaecrista species native to different biomes in the Brazilian state of Bahia, a major centre of diversity for the genus, was plotted onto an ITS-TrnL-F-derived phylogeny of Chamaecrista. The bacteroids from most of the Chamaecrista species examined were enclosed in symbiosomes (SYM-type nodules), but those in arborescent species in the section Apoucouita, at the base of the genus, were enclosed in cell wall material containing homogalacturonan (HG) and cellulose (FT-type nodules). Most symbionts were Bradyrhizobium genotypes grouped according to the growth habits of their hosts, but the tree, C. eitenorum, was nodulated by Paraburkholderia. Chamaecrista has a range of growth habits that allow it to occupy several different biomes and to co-evolve with a wide range of (mainly) bradyrhizobial symbionts. FTs represent a less intimate symbiosis linked with nodulation losses, so the evolution of SYM-type nodules by most Chamaecrista species may have (a) aided the genus-wide retention of nodulation, and (b) assisted in its rapid speciation and radiation out of the rainforest into more diverse and challenging habitats.
