چکیده
Penyakit layu bakteri yang disebabkan oleh Ralstonia solanacearum merupakan salah satu penyakit penting pada tanaman eukaliptus (Eucalyptus pellita) di Indonesia. Salah pendekatan teknik pengendalian adalah melalui pemanfaatan endofit dan fungi mikoriza arbuskula (FMA). Penelitian ini ditujukan untuk mengevaluasi keefektifan FMA dalam menekan perkembangan bakteri. Terdapat sepuluh kombinasi di-ujikan bibit berumur bulan. Inokulasi R. secara buatan dilakukan tiga bulan setelah introduksi FMA. Percobaan ruang growth chamber. Peubah pengamatan meliputi periode inkubasi, insidensi penyakit, laju agresivitas kolonisasi dengan mengamati cairan (ooze) eukaliptus, pengukuran aktivitas phenylalanine ammonia lyase (PAL), total fenol. Hasil penelitian menunjukkan bahwa perlakuan B5F1 (Paenibacillus polymyxa Glomus mosseae) memiliki kemampuan penekanan tertinggi terhadap yaitu sebesar 100%. Perlakuan inkubasi lebih lama, persentase paling rendah, infeksi penghambatan eukaliptus. Sementara B4F1 (Serratia marcescens G. mampu meningkatkan PAL fenol dibandingkan lainnya. Berdasarkan hasil ini, berpotensi mengendalikan

Arbuscular mycorrhizal fungi ameliorate temperature stress in thermophilic plants.
Biotic interactions can affect the distribution of species across environmental gradients, and as air and soil temperatures increase, plant community response may depend on interactions with symbionts. We measured the effect of elevated soil temperatures on mycorrhizal function and on the response of both plant and fungal symbionts, using fungal inoculum isolated from either high-temperature th...

Toljander, J.F. 2006. Interactions between Soil Bacteria and Arbuscular Mycorrhizal Fungi. Doctoral dissertation. ISSN 1652-6880, ISBN 91-576-7088-9 The extraradical mycelium (ERM) of mycorrhizal fungi constitutes an important pathway for the translocation of energy-rich photoassimilates from plant to soil. Because of the large surface of the mycelium, and its provision of carbon, the ERM poten...
متن کاملPlants and arbuscular mycorrhizal fungi: an evolutionary-developmental perspective.
Arbuscular mycorrhizas (AMs) are widespread symbiotic associations that are commonly described as the result of co-evolution events between fungi and plants where both partners benefit from the reciprocal nutrient exchange. Here, we review data from fossil records, characterizations of AM fungi in basal plants and live cell imaging of angiosperm colonization processes from an evolutionary-devel...

For identification of arbuscular mycorrhizal fungi (AMF), in the late springs of 2004 and 2005, wheat fields in the GolestanProvince (northeast of Iran near the Caspian sea) surveyed and root cores sampled. After extraction of AMF spores and staining roots, 19 AMF identified as follow: Entrophospora infrequens, Glomus caledonium, G. clarum, G. constrictum, G. deserticola, G. eburneum, G. etuni...

The occurrence of arbuscular mycorrhizal (AM) fungi was surveyed along a latitudinal gradient in Arctic Canada including Banks Island (73°N), Devon Island (74°N), Ellesmere Island (76°N), and the Magnetic North Pole at Ellef Ringnes Island (78°N). At Banks Island, AM fungi were present and colonized at a high intensity in all specimens of Potentilla hookeriana Lehm. – Potentilla pulchella R.Br....
