The objective of this study was to evaluate the efficiency of nodulation and N2 fixation of strains Bradyrhizobium recommended for cowpea and soybean when used as inoculants for mung bean in comparison with Bradyrhizobium isolates obtained from mung bean nodules. Although mung bean is considered a promiscuous legume, these results suggest the existence of symbiotic incompatibility with some Bradyrhizobium strains. The efficiency of the elite SEMIA 587 (B. elkanii) and UFLA 3?84 (B. viridifuturi) strains in terms of increased nodulation and plant growth was similar to those of Bradyrhizobium strains isolated from mung bean nodules and, therefore, should be evaluated under field conditions to verify their contribution to biological nitrogen fixation in mung bean. |

The oesophageal glands of earthworms are commonly referred as calciferous glands and they
are present in all species of the family Lumbricidae. Most studies have mainly focused on the
well-known Lumbricus terrestris, however many structural aspects are still unknown for the
majority of the species included in the family and the significance of their secretions remains
uncertain. In this study we provide new insights into the morphology and ultraestructure of several
earthworm species belonging to three genera (Allolobophora, Dendrobaena and Octolasion)
collected from different locations in Europe. Earthworms were hand-sorted in the field and taken
back to the laboratory for removal of the glands by dissection. The morphological studies of the
mineral phases involved in the calcareous secretions were analysed by field emission scanning
electron microscopy (FE-SEM) of the air dried frozen sections. Results showed that the anatomy
of the glands of these three genera falls into three types: (i) pouches and oesophageal
enlargements present (Octolasion), pouches present but no enlargements (Allolobophora),
pouches absent but enlargements present (Dendrobaena). Calcium secretion usually appears
initially to be a ?milky fluid? and in those species with pouches the calcium carbonate crystals
aggregate resulting in bigger concretions of different sizes. The morphological characterisation
of the mineral secreetion using FE-SEM showed that the glandular segments contained
spherulites usually packing the interlamellae spaces. These spherulithic deposits mainly consisted
of ovoid to spherical particles varying in size. In contrast, all the morphologies detected in the
solid concretions stored in the pouches could be classified into spherulithic, mulberry-like
aggregates and rhombohedral crystals. Coalescence between two or more spheres was
occasionally observed leading to the formation of larger aggregates, and possibly to the ultimate
formation of rhombohedral calcite crystals. These results evidence that the differences in the
anatomy of the gland determine the morphology of the calcareous secretion among different
species. MenosThe oesophageal glands of earthworms are commonly referred as calciferous glands and they
