RESEARCH ARTICLE The Chloroplast Genome of Elaeagnus macrophylla and trnH Duplication Event in
2016Co-Authors: Kyoung Su Choi, Ogyeong Son, Seonjoo ParkAbstract:Elaeagnaceae, which harbor nitrogen-fixing actinomycetes, is a plant family of the Rosales and sister to Rhamnaceae, Barbeyaceae and Dirachmaceae. The results of previous molecular studies have not strongly supported the families of Elaeagnaceae, Rhamnaceae, Barbeyaceae and Dirachmaceae. However, chloroplast genome studies provide valuable phylogenetic information; therefore, we determined the chloroplast genome of Elaeaganus macrophylla and compared it to that of Rosales such as IR junction and infA gene. The chlo-roplast genome of Elaeagnus macrophylla is 152,224 bp in length and the infA gene of E. macrophylla was psuedogenation. Phylogenetic analyses based on 79 genes in 30 species revealed that Elaeagnus was closely related toMorus. Comparison of the IR junction in six other rosids revealed that the trnH gene contained the LSC region, whereas E.macrophylla contained a trnH gene duplication in the IR region. Comparison of the LSC/IRb (JLB) and the IRa/LSC (JLA) regions of Elaeagnaceae (Elaeagnus and Shephedia) and Rhamnaceae (Rhamnus) showed that trnH gene duplication only occurred in the Elaeagnaceae. The complete chloroplast genome of Elaeagnus macrophylla provides unique characteristics in rosids. The infA gene has been lost or transferred to the nucleus in rosids, while E.macro-phylla lost the infA gene. Evaluation of the chloroplast genome of Elaeagnus revealed trnH gene duplication for the first time in rosids. The availability of Elaeagnus cp genomes pro-vides valuable information describing the relationship of Elaeagnaceae, Barbeyaceae and Dirachmaceae, IR junction that will be valuable to future systematics studies

Microbiology resource announcements, 2020Co-Authors: Faten Ghodhbane-gtari, Maher Gtari, Stephen Simpson, Krystalynne Morris, Erik Swanson, Abdellatif Gueddou, W. Kelley Thomas, Louis S TisaAbstract:ABSTRACT Frankia sp. strain BMG5.11, which was isolated from Elaeagnus angustifolia nodules, is able to infect other actinorhizal plants, including Elaeagnaceae, Rhamnaceae, Colletieae, Gymnostoma, and Myricaceae. Here, we report the 11.3-Mbp draft genome sequence of Frankia sp. strain BMG5.11, with a G+C content of 69.9% and 9,926 candidate protein-encoding genes.

Frankia soli sp. nov., an actinobacterium isolated from soil beneath Ceanothus jepsonii.
International journal of systematic and evolutionary microbiology, 2020Co-Authors: Maher Gtari, Faten Ghodhbane-gtari, Imen NouiouiAbstract:Actinobacterial strain CjT was directly isolated from soil beneath Ceanothus jepsonii growing in the USA. The strain formed cell structures typical of the genus Frankia including extensive hyphae, vesicles and sporangia, and it effectively nodulated members of the actinorhizal Colletieae, Elaeagnaceae and Myricaceae. The whole-cell hydrolysate of strain CjT was rich in meso-diaminopimelic acid and galactose, glucose, mannose, xylose, ribose and a trace of rhamnose. Tbe polar lipid profile contained phosphatidylinositol, phosphatidylglycerol, diphosphatidylglycerol and glycophospholipid. The menaquinone was predominantly MK-9(H4). The fatty acid profile predominantly consisted of C17 : 1ω8c, iso-C16 : 0, C15:0, C16 : 0 and C17 : 0. A multilocus sequence analysis phylogeny based on atp1, ftsZ, dnaK, gyrA and secA gene sequences positioned the strain within Elaeagnaceae- and Colletieae -nodulating species together with Frankia elaeagni DSM 46783T, Frankia discariae DSM 46785T and Frankia irregularis DSM 45899T. Pairwise 16S rRNA gene sequence similarities showed that strain CjT was most closely related to F. discariae DSM 46785T (99.78 %) while their digital DNA–DNA hybridization value was 41.1 %. Based on the overall analyses, strain CjT (=DSM 100623T=CECT 9041T) warrants classification as the type strain of a novel species, for which the name Frankia soli sp. nov. is proposed.

isolation of elaeagnus compatible frankia from soils collected in tunisia
Fems Microbiology Letters, 2004Co-Authors: Maher Gtari, Gharbi Skander, Lorenzo Brusetti, Diego Mora, Abdellatif Boudabous, Daniele DaffonchioAbstract:The occurrence and diversity of Frankia nodulating Elaeagnus angustifolia in Tunisia were evaluated in 30 soils from different regions by a Frankia-capturing assay. Despite the absence of actinorhizal plants in 24 of the 30 soils, nodules were captured from all the samples. Eight pure strains were isolated from single colonies grown in agar medium. On the basis of 16S rRNA and GlnII sequences, seven strains were clustered with Frankia, colonizing Elaeagnaceae and Rhamnaceae in two different phylogenetic groups while one strain described a new lineage in the Frankia assemblage, indicating that Frankia strains genetically diverse from previously known Elaeagnus-infective strains are present in tunisian soils. Genomic fingerprinting determined by rep-PCR, and tDNA-PCR-SSCP, confirmed the wide genetic diversity of the strains.

sieve element characters of the proteaceae and Elaeagnaceae nuclear crystals phloem proteins and sieve element plastids
Botanica Acta, 1995Co-Authors: H.-d. BehnkeAbstract:The sieve-element characters of 34 species from the Proteaceae and Elaeagnaceae have been studied by transmission electron microscopy. While nondispersive protein bodies and dispersive P-protein are typical components of both families, specific forms and/or their distinctive origin accentuate some taxa. Within the Grevilloideae, subfamily of Proteaceae, a number of Australian species and genera contain protein crystals of nuclear origin arranged into rosette-like bodies, while in the other members studied from the same subfamily no nondispersive protein bodies were found. Several Australian and South African genera of the Proteoideae contain compound-spherical nondispersive protein bodies that reside in the cytoplasm from their very beginning. In the Elaeagnaceae three different P-protein bodies are present of which one is tubular and dispersing, another is nondispersive and of irregular-stellate form, and a third is globular (resembling a P-protein from Cucurbita). The great majority of the species studied from the Proteaceae contains form-Ss sieve-element plastids, Lomatia ilicifolia and Macadamia ternifolia are distinct in having form-Pcs plastids. The average diameter of stem sieve-element plastids in the family is 1.38 μm. The Elaeagnaceae (three species investigated) is a pure form-So family (average diameter: 0.8 μm). There are no specific sieve-element characters that would support any relationship between the Proteaceae and Elaeagnaceae. While affinities of the former to pre-Gondwanan parts of the Rosanae/Myrtanae are discussed, a reconsideration of the Elaeagnaceae as a possible member of the Violanae (identical features with Cucurbitaceae) is proposed.
