Characterization of Bacillus sp. strains isolated from rhizosphere of soybean plants for their use as potential plant growth for promoting Rhizobacteria
Wahyudi, Aris Tri | Astuti, Rina Puji | Widyawati, Asri | Meryandini, Anja | Nawangsih, Abdjad Asih (2011)Rhizobacteria of Bacillus species were isolated from the rhizosphere of soybean plant of Cirebon, Indonesia, and further examined for plant growth promoting activities. A total of 118 isolates identified as Bacillus sp., ... -
Cloning and Overexpression of a Gene Encoding Protein Belong to Tetratricopeptide Involved in Magnetosome Synthesis in Magnetospirillum magneticum AMB-1
Wahyudi, Aris Tri (2006)A genomic DNA fragment involved in magnetosome synthesis was isolated from Magnetospirillum magneticum AMB-I through mini-Tn5 transposon mutagenesis. The DNA fragment flanking transposon from the genomic DNA of a non-magnetic ... -
Cloning of Genomic DNA Fragment Involve in Acid-Aluminium Tolerance in Bradyrhizobium japonicum 38 Through Transposom Mutagenesis
Astuti, Rika Indri | Wahyudi, Aris Tri | Mubarik, Nisa Rachmania (2006)An acid-aluminium sensitive mutant of Bradyrhizobium japonicum 38. designated as AAS38, was generated by mini-Tn5 transposon mutagenesis. The experiment was carried out to identify acid-aluminium tolerance gene (AAT) in ... -
Construction of Genomic Library of Magnetospirillnm magneticum AMB-I and Screening of Genes Involved in Magnetosome Synthesis
Wahyudi, Aris Tri (2005)Magnetospirillum magneticum AMB-1 is a fresh-water magnetic bacterium capable of synthesizing membrane- bound magnetic particle. called magnetosome, under microaerobic conditions. To screen and isolate genes involved in ... -
Evidence for a Link Between Pathogenicity and the Role of Imp Bacterial Transport Effector Proteins in Soybean Infection by Xanthomonas axonopodis pv. glycines
Fitriani, Any | Suwanto, Antonius | Wahyudi, Aris Tri | Tjahjono, Budi (2007)Xanthomonas axonopodis pv. glycines (Xag) is the causal agent of bacterial pustule disease of soybeans. A nonpathogenic mutant of Xag (M715) was constructed employing transposon mutagenesis which showed similar epiphytic ... -
Evidence for a Link Between Pathogenicity and the Role of Imp Bacterial Transport Effector Proteins in Soybean Infection by Xanthomonas axonopodis pv. glycines Vol 1, No 2, 2007
Fitriani, Any | Suwanto, Antonius | Wahyudi, Aris Tri | Tjahjono, Budi (2007)Xanthomonas axonopodis pv. glycines (Xag) is the causal agent at bacterial pustule disease of soybeans. A non-¬pathogenic mutant of Xag (M715) was constructed employing transposon mutagenesis which showed similar epiphytic ... -
Genetic Diversity of Antifungi-Producing Rhizobacteria of Pseudomonas sp. Isolated from Rhizosphere of Soybean Plant
Susilowati, Ari | Wahyudi, Aris Tri | Lestari, Yulin | Wiyono, Suryo | Suwanto, Antonius (2010)Antifungi-producing rhizobacteria have been regognize playing an important role in plant desease supression. In our laboratory, 13 indigenous soybean rhizobacteria Pseudomonas sp. that showed strong growth inhibition of ... -
Genetic Diversity of Plant Growth Promoting Rhizobacteria of Bacillus sp. Based on 16S rRNA Sequence and Amplified rDNA Restriction Analysis
Bahri, Syamsul | Wahyudi, Aris Tri | Mubarik, Nisa Rachmania (2009)Plant-growth promoting rhizobacteria (PGPR) are rhizosphere associated soil-borne bacteria that can enhance plant growth and inhibit the development of root pathogens. Many soil bacteria have been used as PGPR, and one of ... -
Pembentukan Magnetosom pada Bakteri (Magnetosome Formation in Bacteria)
Wahyudi, Aris Tri (2004)Magnetic bacteria orient and navigate along geomagnetic field lines and are widely distributed in freshwater and marine habitat. The ability of these bacteria to respond to magnetic fields is based on the presence of ... -
Perpustakaan Gen: Bagaimana Mengonstruksinya?
Wahyudi, Aris Tri (2001)Many methods can be used to construct genomic DNA library in the cosmid vector. In this system, large fragments of genomic DNA generated by randomly digestion are ligated to the cosmid vector to form concatemers that can ... -
