Endophytic fungi were isolated from leaves of Rhizophora apiculata Bl. and Rhizophora mucronata Lamk., two typical mangrove plants growing in the Pichavaram mangrove of Tamil Nadu, Southern India. Three hundred leaf segments from each plant species were sampled during dry and rainy months. More endophytes could be isolated during the rainy months than during the dry period. Hyphomycetes and sterile forms were more prevalent than ascomycetes or coelomycetes. Sporormiella minima, Acremonium sp. strain MG1 and a sterile fungus (MG90) were isolated from both plants irrespective of the season. Some endophytes were common to both plants, although a few appeared to be host specific. This is the first report on fungal endophytes in leaves of mangrove plants in India.Key words: endophytic fungi, Rhizophora apiculata, Rhizophora mucronata, mangrove, leaves.

Langsa merupakan salah satu kota pesisir Aceh yang memiliki kawasan mangrove yang  sangat  potensial.  Kota  ini  memiliki  panjang  garis  pantai  16  km dengan luas kawasan mangrove sebesar 7.837 Ha. Keberadaan mangrove di wilayah ini menjadi aset strategis untuk dikembangkan menjadi basis kegiatan ekonomi untuk memakmurkan masyarakat dan meningkatkan pendapatan  asli  daerah. Tujuan utama penelitian ini adalah untuk melestarikan potensi sumberdaya ekosistem mangrove yang ada di Kota Langsa agar dapat memberikan fungsi ekologis dan ekonomis secara berkesinambungan kepada masyarakat disekitarnya. Kajian ini dilakukan menggunakan metode survei, analisa laboratorium dan observasi lapangan. Hasil pengamatan terhadap komposisi jenis tumbuhan yang terdapat di ekosistem mangrove menunjukkan 8 jenis tumbuhan mangrove yaitu: jenis Avicennia lanata, Avicennia marina, Bruguiera gymnorrhiza, Bruguiera parviflora, Rhizophora apiculata, Rhizophora  mucronata, Sonneratia Caseolaris dan Xylocarpus granatum. Nilai rata-rata parameter kualitas air di ekosistem mangrove secara beturut-turut adalah DO (6.3 ppm),salinitas (27 ‰), pH tanah dasar (6.0), pH tanah permukaan (5.08), pH air (7.33), suhu (30 oC) dan kecerahan (5 m).  Perhitungan terhadap nilai manfaat ekosistem mangrove meliputi: 1) Nilai manfaat langsung perikanan tangkap: Rp. 8.710.000.000 per tahun, 2) Nilai manfaat budidaya tambak: Rp. 93.940.000.000,- per tahun, 3) Nilai penahan abrasi dan banjir: Rp. 300.000.000,- per hektar per tahun, 4) Nilai sebagai penyediaan unsur hara: Rp. 28.634.000,- per tahun, 5) Nilai manfaat pilihan: Rp. 210.000.000,- per tahun dan 6) Nilai manfaat keberadaan: Rp. 1.464.493.000,- per tahun.  Nilai keberadaan ekosistem mangrove yang dinilai adalah Nilai Keaslian = 70 % (lebih dari asli), Nilai Keindahan Alam = 74 % (lebih dari indah), Nilai Kenyamanan = 66% (kondisi lebih dari nyaman),  dan Nilai Aspirasi masyarakat = 98 % (sangat didukung masyarakat). Alternatif  pengelolaan  dan  pemanfaatan  ekosistem  mangrove  yang diperkirakan cocok secara ekonomi dan ekologis terdiri dari beberapa kegiatan pilihan yaitu budidaya ikan, udang, tiram dan kepiting, budidaya ikan kerapu dan kakap, pengolahan buah dan daun mangrove, dan pengembangan obyek wisata.

Abundant Element

Silicon (Si) is the second most abundant element in soil after oxygen. It is not an essential element for plant growth and formation but plays an important role in increasing plant tolerance towards different kinds of abiotic and biotic stresses. The molecular mechanism of Si absorption and accumulation may differ between plants, such as monocotyledons and dicotyledons. Silicon absorption and accumulation in mangrove plants are affected indirectly by some proteins rich in serine and proline amino acids. The expression level of the genes responsible for Si absorption varies in different parts of plants. In this study, Si is mainly observed in the epidermal roots’ cell walls of mangrove plants compared to other parts. The present work was carried out to discover further information on Si stress responsive genes inRhizophora apiculata, using the suppression subtractive hybridization technique. To construct the cDNA library, two-month-old seedlings were exposed to 0.5, 1, and 1.5 mM SiO2for 15 hrs and for 1 to 6 days resulting in a total of 360 high quality ESTs gained. Further examination by RT-PCR and real-time qRT-PCR showed the expression of a candidate gene ofserine-rich protein.

<p>Ten fungal strains isolated from <em>Edgeworthia chrysantha</em>, one of traditional medicinal plants in China, were evaluated their antimicrobial activities against three human pathogens, <em>Escherichia coli, Staphyloccocus aureus and Candida albicans</em>, and two phytopathogens, <em>Rhizoctonia cerealis</em> and <em>Colletotrichum gloeosporioides</em>. The results indicated that most ethyl acetate extracts of fermentation broth of these fungal endophytes had stronger antimicrobial activities than their fermentation broth. Among these endophytic strains, both fermentation broth and the ethyl acetate extract of strain D showed the strongest inhibitory effects on all pathogens. Strains 5-19 and BZ also exhibited potent antibacterial activities. However, other strains had weak or no antimicrobial effect. This was the first report on the isolation and antimicrobial effects of endophytic fungi from <em>E. chrysantha</em>.   </p><p> </p>

Penyakit infeksi masih menjadi masalah utama di Dunia, terutama dinegara berkembang seperti Indonesia. Staphylococcus aureus dan Salmonella typhi merupakan bakteri gram positif dan bakteri gram negatif yang masih menjadi penyebab infeksi tersering. Penggunaan antibiotic yang tidak tepat dapat merusak flora normal dan menyebabkan resistensi. Kopi mengandung senyawa kimia flavonoid dan alkaloid yang mempunyai aktivitas antibakteri. Tujuan dari penelitian ini adalah untuk mengetahui aktivitas antibakteri fraksi etil asetat dari ekstrak etanol biji kopi robusta terhadap pertumbuhan bakteri Salmonella typhi dan Staphylococcus aureus. Metode ekstraksi yang digunakan adalah maserasi  dengan pelarut etanol 70% dan dilakukan fraksinasi dengan metode cair-cair menggunakan pelarut etil asetat. Pengujian antibakteri menggunakan metode difusi agar disk dengan konsentrasi 2.5%, 5%, 10% dan 15%. Hasil penelitian fraksi etil asetat dengan konsentrasi 15% untuk bakteri Salmonella typhi memiliki zona hambat sebesar 8.13 mm dan bakteri Staphylococcus aureus memiliki zona hambat 3.8 mm. Semakin besar konsentrasi fraksi etil asetat semakin besar zona hambat yang terbentuk pada media agar.

Phenology of tropical forest plant is a population factor and does not include community factor, this is caused by a genetic determinationand also the influence of the environment. Phenology of plants in mangrove correlated with the time of flowering, fruiting, and productionof fruits or propagules. Phenology research in mangrove plants in the Unggas Island, West Pasaman, done with ‘tagging’ technique method.Signs made of plastic and are numbered. Data collection included from the formation of flower blooming, up to the formation of fruit orpropagules ripe. Phase of the development is categorized to two categories: (a) flower, and (b) fruit. The analysis method is the analysis ofvariance (ANOVA, p<0.01) and post-hoc test, Duncans Multiple Range Test (DMRT, p<0.01) to obtain comparison and differencesbetween the components of flower, flower fall, fruit, and fruit maturity.

Background: Mangrove forests are one of the unique natural ecosystems with high ecological value. Mangrove ecosystems are one of the areas with high productivity because there are litter and decomposition of litter and detritus occurs. This study was conducted to determine the association between gastropods and mangrove plants. Method: Research on gastropod association with mangrove plants in the coastal waters of Tiouw Village and Haria Village was conducted in January 2018. Results: This study found from gastropods 6 species namely variabilis strombus, microurceus strombus, Nassarius luridus, Strombus urceus, Cypraea annulus, Strombus, Strombus, Nerita squamulata. From the mangrove plants, 10 species were found: Avicennia eucalyptifolia, Avicennia lanata, Bruguiera sexangula, Rhizophora apiculata, Bruguiera hainessi, Aegiceras floridum R, Aegiceras curniculatum L, Bruguiera palviflora, Bruguiera exaristafa, Ceriops tagal. Conclusion: Association values ​​ranged from 0.741-0.9773 with positive and negative types. This means that both types of seagrass are often found together or not found together in the observation location
