Powdery mildew-infected rainforest spinach (Elatostema reticulatum) plants were found in Queensland, Australia. Based on morphology and nrDNA ITS sequence analyses, the pathogen was identified as Podosphaera xanthii, a powdery mildew species with worldwide distribution broad host range. This is first record of P. xanthii infecting E. reticulatum, infection recorded for this native Australian pl...

Antibodies against nitrate reductase from Monoraphidium braunii have been used to determine the antigenic relationships of nitrate reductases from different green algae. Nitrate reductases from Chlamydomonas reinhardii, Chlorella fusca, Dunaliella salina, and Scenedesmus obliquus, were inhibited by, and cross-reacted with, antibodies raised against the enzyme from Monoraphidium braunii.These an...

Chemical investigation of the marine sponge Ircinia fusca leads to isolation of a new pyrrole derivative (1) and two known compounds namely, 3 methyl decanoic acid (2) and Benzenedicarboxylic acid (3). The structures of compounds were established by 1D and 2D NMR and MS data. Compound 1 exhibited strong antibacterial activity against Mycobacterium smegmatis at MIC 116 μM. Compounds 1-3 showed n...
