Abstract: This study deals with seven of the eight genera represented in Australia. (Cassytha is not included because it was revised by Weber (1981)). Beilschmiedia: 11 species including 6 new species, B. brunnea, B. castrisinensis, B. collina, B. peninsularis, B. recurva, volckii and one new combination B. tooram. Cinnamomum: 5 species. Cryptocarya: 46 species including 21 new species, C. bamagana, C. bellendenkerana, C. clarksoniana, C. claudiana, C. cocosoides, C. dorrigoensis, C. glaucocarpa, C. grandis, C. leucophylla, C. lividula, macdonaldii, C. melanocarpa, C. nova-anglica, C. onoprienkoana, C. putida, C. rhodosperma, C. saccharata, C. sclerophylla, C. smaragdina, C. vulgaris, C. williwilliana and two new varieties C. triplinervis var. pubens and C. triplinervis var. riparia. Endiandra: 38 species including 14 new species, E. bellendenkerana, E. bessaphila, E. collinsii, E. cooperana, E. floydii, E. grayi, E. ionesii, E. leptodendron, E. limnophila, E. monothyra, E. phaeocarpa, E. sideroxylon, E. wolfei, E. xanthocarpa and two new subspecies E. muelleri ssp. bracteata and E. monothyra ssp. trichophylla. Lindera: one new species, L. queenslandica. Litsea: 11 species including 4 new species, L. australis, L. bennettii, L. connorsii, L. granitica. Neolitsea: 3 species.
TL;DR: Evidence is provided that at least three proteins of these two complexes are not essential in the FtsZ-less ovoid planctomycete bacterium Planctopirus limnophila which divides via budding using an unknown mechanism.
Abstract: Most bacteria divide by binary fission using an FtsZ-based mechanism that relies on a multi-protein complex, the divisome. In the majority of non-spherical bacteria another multi-protein complex, the elongasome, is also required for the maintenance of cell shape. Components of these multi-protein assemblies are conserved and essential in most bacteria. Here, we provide evidence that at least three proteins of these two complexes are not essential in the FtsZ-less ovoid planctomycete bacterium Planctopirus limnophila which divides by budding. We attempted to construct P. limnophila knock-out mutants of the genes coding for the divisome proteins FtsI, FtsK, FtsW and the elongasome protein MreB. Surprisingly, ftsI, ftsW and mreB could be deleted without affecting the growth rate. On the other hand, the conserved ftsK appeared to be essential in this bacterium. In conclusion, the canonical bacterial cell division machinery is not essential in P. limnophila and this bacterium divides via budding using an unknown mechanism.
Abstract: The genus Australonura Cassagnau 1980 is newly recorded from South America. The Patagonian species Paleonura limnophila (Cassagnau & Rapoport, 1962) and Paleonura friasica Cassagnau & Oliveira, 1990 are redescribed from type material and recombined in Australonura. A new species, A. paraguayensis sp. nov., is described from Paraguay and assigned to Australonura for its head tubercle arrangement. It differs from other species of the genus by its adjacent but separate dorso-internal tubercles of Abd. V.
TL;DR: In this paper, the authors investigated the antioxidant activity of methanol extract of roots of Limnophila heterophylla (Plantaginaceae) for free radical scavenging.
