J-Hude Moudingo, ... Minette Tomedi, in Biotechnological Utilization of Mangrove Resources, 2020. Laguncularia racemosa (L.) C.F.Gaertn. Cerrado tree species and palms occupy the high-ground islands of the Pantanal. J.L. RAPD employs the PCR amplification of a DNA fragment with short primers (usually of 10 bp) followed by random annealing under low temperature conditions. Avicennia alba methanolic extracts inhibited the Micrococcus luteus, P. aeruginosa, and B. subtilis strains (Eswaraiah et al., 2019a,b). Most of the results are in line with those of some authors (Ajonina, 2008; Ajonina et al., 2014a,b; Eugene et al., 2014) but showed more plant association presence. Description and Adaptation Black mangrove is a subtropical woody shrub that grows in salt marshes. Stadler and Müller (1996) and Stadler et al. The Gulf of Mexico corresponds to a marginal sea coast with a typical low-relief extensive coastal plain and shelf (Inman and Nordstrom, 1971). The northwest coast has an arid-temperate climate with less than 500 mm of annual rainfall (Fig. Genus. With the exception of HE areas, true mangrove mortality was generally above recruitment in all the sites studied. X. moluccensis is a true mangrove plant possessing antiviral activities against pandemic influenza A virus (Li et al., 2015). However, we found that N. fruticans, a nonnative species, showed some kind of ecological association (present and coexisting). (2003) found that predation by a scolytid beetle, Coccotrypes rhizophorae, on seedlings of the mangrove, Rhizophora mangle, prevented establishment of R. mangle in lightning-generated gaps and permitted a shade-intolerant species, Laguncularia racemosa, to co-dominate the mangrove community on the Caribbean coast of Panama. Sousa et al. (1997, 1998) reported that microbial biomass, nematode abundance, and soil respiration rates were consistently reduced by removal of sheep grazing (Fig. In this technique, the hypervariable region of the 16S rRNA gene is targeted to generate the unique profile to distinguish among the microbial communities (Joo, Han, Lee, & Park, 2014). In addition, Nypa palm might be among the most conspicuous understory vegetation (i.e., nonmangrove tree) following the report of Snedaker and Lahmann (1988). Bark extracts of the E. agallocha plant exhibits antiulcer activity (Thirunavukkarasu et al., 2009). Similarly Lumnitzera racemosa leaf extract also has showed anticancer activity against MCF7 and HeLa cell lines (Eswaraiah et al., 2019a,b). Blechum pyramidatum (Lam.) In the Nypa palm natural habitat of South and Southeast Asia and Oceania countries (like in Malaysia, Indonesia, Philippines, Thailand, etc. Therefore the common name air roots. Copyright © 1999 Elsevier Science B.V. All rights reserved. Likewise, Atheull et al. The methanol extract of C. manghas has antiinflammatory activity due to the kaempferol in extracts, which is a flavonol; this compound shows antiinflammatory activity by inhibiting the NF-kB and SyK/Src pathways (Jeong et al., 2014). The fundamentals behind genetic fingerprinting involve the detection of either length or sequence polymorphism among the microbial communities present within the target genetic fragment (Danovaro, Luna, Dell'Anno, & Pietrangeli, 2006). 12.11). Among all these plants, R. mucronata has the greatest activity (Ravikumar et al., 2011). Higher values occur during the rainy season (September) and lowest during nortes (February), with slightly higher values for Boca Chica. Hirak Ranjan Dash, Surajit Das, in Methods in Microbiology, 2018. Plant communities directly influenced by seawater but occupying high grounds are characterized by genera typical of seashore environments: Remirea, Salicorna, Canavalia, Acicarpa, and Vignia. Similarly, RISA was also found to be a useful tool in monitoring the variation in methanogenic archaeal diversity for about 6 months in an atypical environment, i.e., a digester treating plant biomass (Ciesielski et al., 2013). Similarly, A. marina ethanolic extracts also have antidiabetic activity (Babuselvam et al., 2013). Combretaceae, white mangrove family. The direction of succession then depends on which plant species are present and their responses to environmental conditions. These pollutants may kill algae and invertebrates that live on roots and interferes with the oxygen supply by blocking the respiratory pores on prop roots … Pneumatophores are thought to function as the trees' means of obtaining oxygen for the roots during flooded conditions. Therefore, we carried out experiments with shoot cuttings of Laguncularia racemosa and Rhizophora mangle under controlled conditions as well as in the field to prove the feasibility of vegetative propagation in these mangrove species. Differential herbivory among plants and plant species in an ecosystem affects both the distribution of individuals of a particular plant species and the opportunities for growth of plant species resistant to or tolerant of herbivory. Plant extracts have more advantages, compared with synthetic drugs or English (Western) medicine, for the treatment of various disorders, and these plant extracts are presumed to be safe and do not show any side effects. Seasonal variation in microbial biomass and nematode abundance in grazed and ungrazed plots of two grassland types in Ireland. Therefore, delta plains and estuarine conditions, which are preferred by mangroves, are less common (Lankford, 1977). Source waters were collected from bodies of water surrounding the whole-plant root systems. Both ARDRA and TRFLP use the same principle, however, in the case of TRFLP primers are labelled with 5′ fluorescently labelled dye. (2016), who demonstrated that Nypa does not thrive on the closed UND mangrove vegetation in Nigeria. To the first type belong the freshwater swamp forests of the Atlantic coast between the Orinoco delta and the mouth of the Parnaiba River. Vertical lines represent standard errors; *, P < 0.05, **, P < 0.01; ***, P < 0.001. Brown and Gange (1989) found that reduced below-ground herbivory resulted in higher plant species richness, largely reflecting differential intensities of herbivory among various grass and forb species. In certain instances, DNA molecules are present in the form of a secondary folded structure (known as a heteroduplex) which is dependent on the DNA sequences and governs the mobility of DNA on the gel. Similarly, Vibrio vulnificus isolated from different geographic regions generated different RAPD profiles suggesting its utility to a greater efficacy in atypical environments (Arias, Pujalte, Garay, & Aznar, 1998). However, the major limitation of SSCP is that, in addition to DNA sequences, many other factors also contribute to the secondary confirmation of DNA complicating the analysis of the obtained results (Svozil, Kalina, Omelka, & Schneider, 2008). Schousboea commutata Spreng. Stem and twig extracts of Ceriops tagal has antifeedant activity (Du et al., 2011). Shoot biomass was inversely related to leaf area removed by herbivores. White Mangrove or White Buttonwood (Laguncularia racemosa) is native to the tidal marshes/swamps, lagoons, islets, brackish estuaries, mangrove swamps, barrier islands, and brackish, salty shorelines … extracts inhibit α-glucosidase activity due to the presence of palmitic acid (Cherigo and Martínez-Luis, 2018). Under conditions of adequate moisture (riparian corridors and high elevations), mountain pine beetle advances succession by facilitating the replacement of host pines by the more shade-tolerant, fire-intolerant, understory firs. Mangrove plants such as Avicennia germinans and Rhizophora mangle have antibacterial properties. The arcuate stilt roots have countless lenticels which serve the gas exchange. High intensities during outbreaks or as a result of management can dramatically reduce the abundance of preferred species and rapidly alter vegetation structure and composition. 10.5). Additionally, burying a small part of the roots in a way that allows some roots to freely float in the surface water, improves the survival rate to 95%. As a result, the numbers of DNA fragments of varied length are generated and subsequent separation on agarose or polyacrylamide gels exploit the genetic complexities of a microbial community present in an atypical environment (Malik, Kain, Pettigrew, & Ogram, 1994). Seasonal floodings of lower branches induce secondary root growth and can even lead to natural vegetative propagation. Prop roots are tall arching roots originating from trunks and branches. It is best suited for biotopes that allow for the root system to be partially above the water line. These activities are regulated by the nitric oxide (NO) in A. corniculatum, used to withstand the salt stress, showing that NO acts as an antioxidant under salt stress conditions in mangrove plants (Chen et al., 2014).
