[Ab] Resumo:The retention of CdS/ZnS QDs on the epidermis has been confirmed to be one of the core procedures during the root uptake process. However, the retention mechanisms of QDs on the epidermis of woody plant were poorly understood for lacking of an appropriate QD quantitative method. In this study, a novel method for in situ determination of CdS/ZnS QDs retained on the root epidermis was established using synchronous nanosecond time-resolved fluorescence spectroscopy. No correlations between K values of oleylamine-CdS/ZnS QDs retained on the epidermal tissues and the surface/bulk composition of mangrove root were observed (p > 0.05) due to the existence of endocytosis mechanisms during the QD uptake processes. Moreover, the difference of the CdS/ZnS QDs in water and further translocated to xylem/phloem of root rather than the combination with cell wall/membranes was the predominant reason that caused the K values to follow the sequence of PEG-COOH-CdS/ZnS QDs < PEG-NH -CdS/ZnS QDs ≪ oleylamine-CdS/ZnS QDs.

[Ab] Resumo:A novel, rod-shaped, Gram-stain-negative, halophilic and non-motile bacterium, designated CCB-MM1 , was isolated from a sample of estuarine sediment collected from Matang Mangrove Forest, Malaysia. The cells possessed a rod-coccus cell cycle in association with growth phase and formed aggregates. Strain CCB-MM1 was both catalase and oxidase positive, and able to degrade starch. Optimum growth occurred at 30 °C and pH 7.0 in the presence of 2-3 % (w/v) NaCl. The 16S rRNA gene sequence of strain CCB-MM1 showed 98.12, 97.46 and 97.33 % sequence similarity with Microbulbifer rhizosphaerae Cs16b , Microbulbifer maritimus TF-17 and Microbulbifergwangyangensis GY2 respectively. Strain CCB-MM1 and M. rhizosphaerae Cs16b formed a cluster in the phylogenetic tree. The major cellular fatty acids were iso-C17 : 1 ω9c and iso-C15 : 0, and the total polar lipid profile consisted of phosphatidylglycerol, phosphatidylethanolamine, phosphoaminolipid, two unidentified lipids, an unidentified glycolipid and an unidentified aminolipid. The major respiratory quinone was ubiquinone Q-8 and the genomic DNA G+C content of the strain was 58.9 mol%. On the basis of the phylogenetic, phenotypic and genotypic data presented here, strain CCB-MM1 represents a novel species of the genus Microbulbifer, for which the name Microbulbiferaggregans sp. nov. is proposed. The type strain is CCB-MM1 (=LMG 29920 =JCM 31875 ).

[Ab] Resumo:A novel bacterial strain, designated HSG9 , was isolated from aisolated from a rotten tropical mangrove root. Cells of strain HSG9 were aerobic, Gram-stain-negative, yellow, oxidase-negative and catalase-positive. Growth was observed in 0.5-9 % sea salt (optimum 3 %, w/v), at 10-42 °C (optimum 25-35 °C) and at pH 6.0-8.0 (optimum 7.0-8.0). Gelatin, esterase and Tweens 20, 40, 60 and 80 were hydrolysed, but starch, protein, cellulose and casein were not. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain HSG9 formed an independent lineage related to the family Flavobacteriaceae. The dominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G. The respiratory quinone was identified as MK-6 and the polar lipids were phosphatidylethanolamine, three unidentified phospholipids and an unidentified lipid. The DNA G+C content was 37.1 mol%. The combined genotypic and phenotypic data indicated that strain HSG9 represents a novel species of a new genus within the family Flavobacteriaceae, for which the name Croceivirgaradicis gen. nov., sp. nov. is proposed. The type strain is HSG9 (=MCCC 1A06690 =KCTC 52589 ).

[Ab] Resumo:A novel Gram-stain-positive actinobacterium, designated HIs16-32T, was isolated from a sand sample collected from a mangrove tidal flat in Japan and its taxonomic position was investigated by a polyphasic approach. The cells of strain HIs16-32T were Gram-stain-positive, rod-shaped, non-motile and non-endospore-forming. Strain HIs16-32T contained glutamic acid, glycine and lysine in the peptidoglycan; however, alanine was absent. Galactose and mannose were detected as cell-wall sugars. The isoprenoid quinones were identified as MK-11, MK-12 and MK-10, and the major fatty acids as anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The DNA G+C content was determined to be 72.2 mol%. Phylogenetic analyses based on 16S rRNA gene sequence comparison revealed that strain HIs16-32T was related to members of the family Microbacteriaceae but did not form a reliable cluster with any known members of the family. The highest 16S rRNA gene sequence similarity values were obtained with species of the genera Herbiconiux(96.1-96.8 %), Plantibacter(96.5-96.7 %) and Schumannella (96.7 %). However, strain HIs16-32T was distinguishable from the phylogenetically related genera in terms of chemotaxonomic characteristics and phylogenetic relationship. Therefore, strain HIs16-32T is concluded to represent a novel genus and species of the family Microbacteriaceae, for which the name Arenivirga flava gen. nov., sp. nov. is proposed. The type strain of A. flava is HIs16-32T (=NBRC 112289T=TBRC 7038T).

[Ti] Título:Reduced genetic diversity and alteration of gene flow in a fiddler crab due to mangrove degradation.

[Ab] Resumo:The fiddler crab Austruca occidentalis is a dominant species in mangrove forests along the East African coast. It enhances soil aeration and, through its engineering activities, makes otherwise-inaccessible food available for other marine organisms. Despite its importance, the habitat of A. occidentalis is threatened by human activities. Clearing the mangroves for salt farming and selective logging of mangroves trees continue to jeopardise mangrove ecosystems in the Western Indian Ocean. This study aims to use partial mitochondrial COI gene sequences and nuclear microsatellites to determine whether salt farming activities in mangroves have a negative impact on the genetic diversity and gene flow of A. occidentalis collected along the Tanzania coast. The level of genetic diversity for both mitochondrial DNA and nuclear microsatellites are relatively lower in samples from salt ponds compared to natural mangrove sites. Analysis of molecular variance (AMOVA) among all populations showed low but significant differentiation (COI: Fst = 0.022, P < 0.05; microsatellites: Fst = 0.022, P < 0.001). A hierarchical AMOVA indicates lower but significant genetic differentiation among populations from salt ponds and natural mangroves sites (COI: Fct = 0.033, P < 0.05; microsatellites: Fct = 0.018, P = < 0.01). These results indicate that salt farming has a significant negative impact on the genetic diversity of A. occidentalis. Since higher genetic diversity contributes to a stable population, restoring the cleared habitats might be the most effective measures for the conservation of genetic diversity and hence adaptive potential to environmental change in this species.

[Ab] Resumo:The plant DNA barcoding is a complex and requires more than one marker(s) as compared to animal barcoding. Mangroves are diverse estuarine ecosystem prevalent in the tropical and subtropical zone, but anthropogenic activity turned them into the vulnerable ecosystem. There is a need to build a molecular reference library of mangrove plant species based on molecular barcode marker along with morphological characteristics. In this study, we tested the core plant barcode (rbcL and matK) and four promising complementary barcodes (ITS2, psbK-psbI, rpoC1 and atpF-atpH) in 14 mangroves species belonging to 5 families from West Coast India. Data analysis was performed based on barcode gap analysis, intra- and inter-specific genetic distance, Automated Barcode Gap Discovery (ABGD), TaxonDNA (BM, BCM), Poisson Tree Processes (PTP) and General Mixed Yule-coalescent (GMYC). matK+ITS2 marker based on GMYC method resolved 57.14% of mangroves species and TaxonDNA, ABGD, and PTP discriminated 42.85% of mangrove species. With a single locus analysis, ITS2 exhibited the higher discriminatory power (87.82%) and combinations of matK + ITS2 provided the highest discrimination success (89.74%) rate except for Avicennia genus. Further, we explored 3 additional markers (psbK-psbI, rpoC1, and atpF-atpH) for Avicennia genera (A. alba, A. officinalis and A. marina) and atpF-atpH locus was able to discriminate three species of Avicennia genera. Our analysis underscored the efficacy of matK + ITS2 markers along with atpF-atpH as the best combination for mangrove identification in West Coast India regions.

[Ab] Resumo:A bacterial strain, designated gyp-1T, was isolated from a mangrove in Taiwan and characterized using the polyphasic taxonomic approach. Cells of gyp-1T were Gram-staining-negative, aerobic, poly-ß-hydroxybutyrate-accumulating, non-motile, coccoid or short-rod-shaped and formed cream-coloured colonies. Growth occurred at 15-37 °C (optimum, 25-30 °C), at pH 5.5-7.0 (optimum, pH 6.0) and with 0-4 % NaCl (optimum, 1-2 %). Phylogenetic analyses based on 16S rRNA gene sequences indicated that gyp-1T represented a member of the genus Paracoccus and showed the highest levels of sequence similarity with respect to Paracoccus lutimaris HDM-25T (97.8 %) and Paracoccus aminovorans DM-82T (97.7 %). The major fatty acids (>10 %) of gyp-1T were C18 : 1ω7c and C16 : 0. The polar lipid profile consisted of phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol, an unidentified glycolipid and two unidentified phospholipids. The major isoprenoid quinone was Q-10. The DNA G+C content was 64.6 mol%. The DNA-DNA hybridization value for gyp-1T with P. lutimaris HDM-25T and P. aminovorans DM-82T was less than 50 %. Differential phenotypic properties, together with the phylogenetic inference, demonstrate that gyp-1T should be classified as representing a novel species of the genus Paracoccus, for which the name Paracoccus mangrovi sp. nov. is presented. The type strain is gyp-1T (=BCRC 80920T=LMG 29172T=KCTC 42899T).

[Ab] Resumo:A facultatively anaerobic, endospore forming, alkali-tolerant, Gram-stain-positive, motile, rod-shaped bacterium, designated strain AK61T, was isolated from a sediment sample collected from Coringa mangrove forest, India. Colonies were circular, 1.5 mm in diameter, shiny, smooth, yellowish and convex with entire margins after 48 h growth at 30 °C. Growth occurred at 15-42 °C, with 0-3 % (w/v) NaCl and at pH 6-9. AK61T was positive for amylase activity and negative for oxidase, catalase, aesculinase, caseinase, cellulase, DNase, gelatinase, lipase and urease activities. The fatty acids were dominated by branched types with iso- and anteiso- saturated fatty acids with a high abundance of iso-C14 : 0, iso-C15 : 0, anteiso-C15 : 0 and iso-C16 : 0; the cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid; and MK-7 was the major menaquinone. DNA-DNA hybridization between AK61T and Bacillus indicus MTCC 4374T and between AK61T and Bacillus indicus KCTC 3880 showed relatedness of 37.99 and 33.32 % respectively. The DNA G+C content of AK61T was 44 mol%. The results of a blast sequence similarity search based on 16S rRNA gene sequences indicated that Bacillus cibi and Bacillus indicus were the nearest phylogenetic neighbours, with a pair-wise sequence similarity of 97.69 and 97.55 % respectively. The results of phylogenetic analysis indicated that AK61T was clustered with Bacillus idriensis and Bacillus indicus. On the basis of its phenotypic characteristics and phylogenetic inference, AK61T represents a novel species of the genus Bacillus, for which the name Bacillus mangrovi sp. nov. is proposed. The type strain is AK61T (=JCM 31087T=MTCC 12015T=KCTC 33872T).

[Ab] Resumo:Mangrove forests of a single trees species, Avicennia marina subsp. australasica are widespread in the upper North Island of New Zealand, but there is little available information on the diversity of epiphytes such as lichens within them. A survey of 200 trees from 20 mangrove sites recorded a total of 106 lichen species from 45 genera. Two of these species are considered to be 'Threatened', five 'At Risk' and 27 'Data Deficient'. Multiple regression indicated that tree diameter (DBH) and mean annual rain days positively influenced site species richness. Multidimensional scaling showed that sites from the same geographical region generally formed distinct clusters. Redundancy analysis indicated that mean annual wet days, latitude and DBH measurably influenced species composition.

[Ab] Resumo:The polycyclic aromatic hydrocarbons (PAHs) located on the epidermal tissues showed distinctive toxic effects to root, while the retention and distribution of PAHs on mangrove seedlings poorly understood. Our results confirmed that the partition coefficients (K ) of the PAHs retained on the epidermal tissue of mangrove roots, such as Kandelia obovata, Avicennia marina and Aegiceras corniculatum, were much higher than the Poaceae plants roots, for example wheat and maize (Wild et al., 2005). Moreover, to the parent and alkyl PAHs, a well negative correlation was observed between the surface polarity of these three species of mangrove root and the K values (p < 0.05). To the N/O/S containing PAHs, these relationships were not obviously due to existing of the π-π, n-π interactions and hydrogen bonding between the N/O/S-containing PAHs and epidermal tissues. The PAHs retained on these three species of mangrove root epidermal tissues formed larger clusters than that of on Poaceae plants, such as wheat and maize (Wild et al., 2005) due to the limitation of the suberization of the root exodermis and endodermis. After exposure of 30 d, rhizo- and endophytic bacteria degraded parts of the N/O/S-containing PAHs to medium-lifetime fluorescence substances. To our knowledge, this is the first time to assess the retention of PAHs on the epidermal tissue of mangrove root, which will improve our understanding of the root uptake PAHs process.
