The stingless bee Melipona mandacaia popularly known as mandacaia is endemic to the Caatinga biome, being found in the region of Vale do São Francisco. It is a very important bee for meliponiculture in the municipalities of Petrolina (PE) and Juazeiro (BA), where they are used for honey production. Due to its importance and endemism, the mandaçaia has been the subject of research, mainly due to the fact that there is little information about the species, together with the great demand for the rational creation and commercialization of its products. Profile of compounds by Ultra-Performance Liquid Chromatography coupled with a Diode Array Detector and quadrupole Time of Flight Mass Spectrometry MS/MS) of sixteen Melipona mandacaia honeys from semiarid region of the Northeast of Brazil are presented. The melissopalynological analysis showed one principal pollen types of Mimosa tenuiflora (jurema preta). Mandaçaia monofloral honeys have similar characteristic profile of phenolic compounds. Fifty-three compounds were identified, mainly phenolic derivatives. Forty aglycone flavonoids: 26 flavones/flavonols and 14 flavanones/flavanonols. |

The importance of horizontal gene transfer (HGT) in the evolution and speciation of bacteria has been emphasized; however, most studies have focused on genes clustered in pathogenesis and very few on symbiosis islands. Both soybean (Glycine max [L.] Merrill) and compatible Bradyrhizobium japonicum and Bradyrhizobium elkanii strains are exotic to Brazil and have been massively introduced in the country since the early 1960s, occupying today about 45% of the cropped land. For the past 10 years, our group has obtained several isolates showing high diversity in morphological, physiological, genetic, and symbiotic properties in relation to the putative parental inoculant strains. In this study, parental strains and putative natural variants isolated from field-grown soybean nodules were genetically characterized in relation to conserved genes (by repetitive extragenic palindromic PCR using REP and BOX A1R primers, PCR-restriction fragment length polymorphism, and sequencing of the 16SrRNA genes), nodulation, and N2-fixation genes (PCR-RFLP and sequencing of nodY-nodA, nodC, and nifH genes). Both genetic variability due to adaptation to the stressful environmental conditions of the Brazilian Cerrados and HGT events were confirmed. One strain (S 127) was identified as an indigenous B. elkanii strain that acquired a nodC gene from the inoculant B. japonicum. Another one (CPAC 402) was identified as an indigenous Sinorhizobium (Ensifer) fredii strain that received the whole symbiotic island from the B. japonicum inoculant strain and maintained an extra copy of the original nifH gene. The results highlight the strategies that bacteria may commonly use to obtain ecological advantages, such as the acquisition of genes to establish effective symbioses with an exotic host legume.
