Genome wide identification and characterization of MATE family genes in mangrove plants. Genetica 2023:10.1007/s10709-023-00186-w. [PMID: 37014491 DOI: 10.1007/s10709-023-00186-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 03/28/2023] [Indexed: 04/05/2023]
Abstract
Multidrug and Toxic Compound Extrusion (MATE) proteins are essential transporters that extrude metabolites and participate in plant development and cellular detoxification. MATE transporters, which play crucial roles in the survival of mangrove plants under highly challenged environments, by specialized salt extrusion mechanisms, are mined from their genomes and reported here for the first time. Through homology search and domain prediction in the genome assemblies of Avicennia marina, Bruguiera sexangula, Ceriops zippeliana, Kandelia obovata, Rhizophora apiculata and Ceriops tagal, 74, 68, 66, 66, 63 and 64 MATE proteins, respectively were identified. The phylogenetic analysis divided the identified proteins into five major clusters and following the clustering pattern of the functionally characterized proteins, functions of the transporters in each cluster were predicted. Amino acid sequences, exon-intron structure, motif details and subcellular localization pattern for all the 401 proteins are described. The custom designed repeat masking libraries generated for each of these genomes, which will be of extensive use for the researchers worldwide, are also provided in this paper. This is the first study on the MATE genes in mangroves and the results provide comprehensive information on the molecular mechanisms enabling the survival of mangroves under hostile conditions.

Comparative antihyperglycemic, analgesic and anti-inflammatory potential of ethanolic aerial root extracts of Ceriops decandra and Ceriops tagal: Supported by molecular docking and ADMET analysis. Heliyon 2023; 9:e14254. [PMID: 36938384 PMCID: PMC10015254 DOI: 10.1016/j.heliyon.2023.e14254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 02/21/2023] [Accepted: 02/28/2023] [Indexed: 03/07/2023] Open
Abstract
Ceriops decandra (Griff.) (CD) and Ceriops tagal (Perr.) (CT) are two mangrove plants of the Sundarbans distributed along the coastal areas of South Asia and South Pacific Africa. Traditionally, these plants are used to treat diabetes, pain, angina, hemorrhage, and ulcer. In this study, we investigated the antioxidative, antihyperglycemic, analgesic, and anti-inflammatory potential of the aerial roots of CD and CT. At first, the antioxidative potential of CD and CT ethanolic extracts were investigated qualitatively and quantitatively by 2,2-diphenyl-1-picryl hydrazyl (DPPH) radical and hydrogen peroxide scavenging assays and by determining total antioxidant capacity. The total phenolic, flavonoid, tannin, and terpenoid contents of CD and CT were also estimated. The extracts' antihyperglycemic, analgesic, and anti-inflammatory potential were evaluated by oral glucose tolerance test, acetic acid-induced writhing test, and formaldehyde-induced paw-edema test, respectively. In vitro α-glucosidase and α-amylase enzyme inhibitory activities were also assessed. The CD and CT extracts were also analyzed using GCMS for the presence of phytochemicals. Then, molecular docking was carried out with α-glucosidase, α-amylase, cyclooxygenase-II (COX-II), 3-lipoxygenase (3-LOX) enzymes using the compounds found in GCMS analysis as well as the previously reported compounds from CD and CT. Finally, the pharmacokinetic and toxicological profiles of eight selected compounds were assessed with SwissADME and admetSAR server. In the antioxidative, antihyperglycemic, analgesic, and anti-inflammatory activity tests, CT extract showed a greater potential than CD extract. In addition, CT extract demonstrated higher α-glucosidase enzyme inhibitory activity in comparison to CD extract although CD extract exhibited better α-amylase enzyme inhibitory activity. Molecular docking studies revealed the presence of potentially bioactive compounds in both CD and CT. 2-(2-methylphenyl)-1-phenyl-(z)-1-propene of CD demonstrated good binding affinities for α-glucosidase, COX-II, and 3-LOX. In addition, 5S*,8S*,9S*,10R*,13S*)-18-hydroxy-16-nor-3-oxodolabr-4(18)-en-15-oic acid had high binding interactions for both α-glucosidase and α-amylase while 2',5,5'-tetramethyl-1,1'-biphenyl, 2-methyl-4-(3'-phenylpropyl)piperidine and decandrin C had high binding interactions for both COX-II and 3-LOX. Finally, 5S*,8S*,9S*,10R*,13S*)-18-hydroxy-16-nor-3-oxodolabr-4(18)-en-15-oic acid, decandrin C, 2-(2-methylphenyl)-1-phenyl-(z)-1-propene and 2-methyl-4-(3'-phenylpropyl)piperidine demonstrated better pharmacokinetic and toxicological properties in the ADMET analysis compared to the others. Hence it can be concluded that the present study supports the traditional usage of CD and CT for diabetes and pain and reveals the presence of bioactive phytochemicals in both.

Abstract
Introduction Ceriops decandra (CD) and Ceriops tagal (CT) are two traditionally used mangrove plants widely distributed along the coastal areas of South Asia, Africa, South Pacific. In this study, we evaluated the diuretic potential of aerial roots of CD, CT and assessed the effectiveness of the plants' terpenoids enriched bioactive constituents against human carbonic anhydrase (hCA) enzyme through molecular docking. Materials and methods Firstly, the acute toxicity of CD and CT was evaluated in mice. In vivo diuretic activity was then studied in mice and the volume of excreted urine was measured. The urine was further examined for pH, density and Na+, K+, Cl- concentrations. From this, the saluretic, natriuretic, kaliuretic and CAI (carbonic anhydrase inhibitory) activities were calculated. Finally, total terpenoid contents (TTC) of the plant extracts were quantified and the terpenoids previously reported from both CD and CT were docked against four hCA isoforms - hCAII, hCAIV, hCAXII and hCAXIV. Results In the acute toxicity assessment, no sign of toxicity was found. In diuretic activity evaluation, both extracts displayed substantial increase in urine volume, with CD being at top. Concentrations of Na+, K+ and Cl- were also upsurged at a high dose of treatment (500 mg/kg). Both extracts at 500 mg/kg dose demonstrated potent saluretic, natriuretic and CAI activity. The TTC of CD was significantly higher than CT. In molecular docking analysis, greater binding affinity against hCA isoforms was demonstrated by the terpenoids reported from CD. Conclusion Aerial roots of both CD and CT possess substantial diuretic activity with an inhibitory effect on CA. Here, diuretic potential as well as the total terpenoid content of CD were much greater between the two.

Abstract
Vomifoliol, a natural sesquiterpene compound, is a secondary metabolite isolated from the mangrove plant Ceriops tagal. The present study aimed to determine the immunosuppressive effects and underlying mechanisms of vomifoliol on Jurkat cells in vitro. The results show that vomifoliol significantly inhibited calcineurin (CN) at concentrations resulting in relatively low cytotoxicity. Moreover, vomifoliol was found to exert an inhibitory effect on phorbol 12-myristate 13-acetate (PMA)/ ionomycin (Io) -induced Jurkat cells and the dephosphorylation of NFAT1. In addition, it reduced the expression of IL-2. Based on these results, we concluded that vomifoliol may inhibit the immune response of Jurkat cells, and vomifoliol may use CN as the target enzyme to inhibit NFAT signaling pathway. Therefore, vomifoliol may be promising as a low-toxic natural immunosuppressant.

Abstract
Little is known regarding the fungi, especially fungal pathogens, associated with mangroves in Africa. This includes fungi in the Botryosphaeriaceae that comprise numerous opportunistic, stress-associated pathogens often associated with trees affected by environmental and anthropogenically generated stresses, such as those affecting mangroves. We investigated the occurrence of endophytic Botryosphaeriaceae along the entire distribution of mangroves in South Africa. Asymptomatic branches were collected from ten localities and six mangrove species. Isolates resembling species of Botryosphaeriaceae were identified based on multi-gene sequence data of the internal transcribed spacer regions (ITS), including the 5.8S nrRNA, the beta-tubulin (tub2), partial translation elongation factor 1-alpha (tef1-α), and DNA-directed RNA polymerase II second largest subunit (rpb2) gene regions. Inoculation trials were conducted on healthy branches of Avicennia marina and Bruguiera gymnorrhiza to evaluate the potential pathogenicity of the collected species. Fourteen species in the Botryosphaeriaceae belonging to four genera, Botryosphaeria, Diplodia, Lasiodiplodia, and Neofusicoccum were collected, including five new species. Neofusicoccum was the most prevalent genus followed by Lasiodiplodia, with species of Diplodia and Botryosphaeria being the least frequent. The inoculation studies revealed that one of the new species, Lasiodiplodia avicenniae is highly pathogenic to A. marina and could pose a threat to the health of these trees.

Abstract
One new dimeric diterpenoid, 8(14)-enyl-pimar-2'(3')-en-4'(18')-en-15'(16')-endolabr- 16,15,2',3'-oxoan-16-one (1) and five known terpenoids: Tagalsin C (2), Tagalsin I (3), lup-20(29)-ene-3β,28-diol (4), 3-oxolup-20(29)-en-28-oic acid (5) and 28-hydroxylup- 20(29)-en-3-one (6) were isolated from the roots of the mangrove plant Ceriops tagal. Their structures and relative stereochemistry were elucidated by means of extensive NMR, IR and MS analysis. The antifouling activity against larval settlement of the barnacle Balanus albicostatus were evaluated using capsaicin as a positive control. All these terpenoids exhibited antifouling activity against cyprid larvae of the barnacle without significant toxicity. The structure-activity relationship results demonstrated that the order of antifouling activity was diterpenoid (Compound 2) > triterpenoid (Compounds 4, 5 and 6) > dimeric diterpenoid (Compounds 1 and 3). The functional groups on the C-28 position of lupane triterpenoid significantly affect the antifouling activity. The diterpenoid dimmer with two identical diterpenoid subunits might display more potent antifouling activity than one with two different diterpenoid subunits. The stability test showed that Compounds 2, 4, 5 and 6 remained stable over 2-month exposure under filtered seawater.
