Abstract
Casuarina equisetifolia L. (Casuarinaceae), an actinorhizal plant, exhibits mutualistic symbiosis with Frankia and promotes nitrogen fixation in root nodules. While the exchange of metabolites between host plant and microsymbiont is well understood in legume symbioses, the situation in the symbiosis between nitrogen-fixing Frankia and actinorhizal plants is less clear. In this study, a metabolomic approach was applied to root nodules of mature C. equisetifolia trees, leading to the identification of an undescribed taraxerane-type triterpenoid ester, 3-O-dihydrocoumaroyl β-taraxerol, along with twelve known compounds. An abundant component was tyramine with a content of 2.76 ± 0.315 mg/g FW in mature nodules. Tyramine specifically and abundantly accumulated in mature nitrogen-fixing nodules compared to senescent nodules, stems, leaves, and seeds. In addition, the potential function of tyramine was preliminarily examined and discussed.

Abstract
Frankia sp. strain B2 was isolated from Casuarina cunninghamiana nodules. Here, we report the 5.3-Mbp draft genome sequence of Frankia sp. strain B2 with a G+C content of 70.1 % and 4,663 candidate protein-encoding genes. Analysis of the genome revealed the presence of high numbers of secondary metabolic biosynthetic gene clusters.

Abstract
• Structure and fungal composition is presented here for 'mycorrhizal' nodules of two angiosperms of the genus Gymnostoma (Casuarinaceae), G. deplancheanum and G. nodiflorum. These species are endemic to New Caledonia, where they grow on ultramafic soils. The mycorrhizal nodules, which are modified lateral roots invaded by an arbuscular mycorrhizal fungus, occur in addition to N2 -fixing nodules. • Techniques included PCR amplification of extracted DNA, for species identification, and histological studies to compare the developmental pathway of Gymnostoma mycorrhizal nodules with that of actinorhizal nodules. • The fungal DNA suggested that the strain belongs to the genus Glomus (Glomales). The endophytic mycelium also contained typical Glomus arbuscules and hyphal coils. Structurally, Gymnostoma mycorrhizal nodules are similar to those described in some Coniferales and in Caesalpinioideae trees of French Guyana. • The mycorrhizal nodules of G. deplancheanum and G. nodiflorum contain a fungus belonging to the Glomales. The role of the nodules might be linked to the ecological situation of the host plants, which are pioneers in exposed and rocky habitats.
