Phytochemical analysis of 3 members the Urticaceae family (eg Pilea pumila, Laportea canadensis, and Boehmeria cylindrica) was conducted using GC-MS. P pumila L canadensis have several recorded historical medicinal uses by Native American tribes, whereas B cylindrica does not. This study to understand in terms chemical composition. Plant material, separated into aerial or root portions, dried e...

The incidence and geographic distribution of leaf scald (Xanthomonas albilineans (Ashby) Dowson) in the Moreton district between 1951 and 1975 is described. Most of the infection has been in 471. Increase in incidence of the disease appears to be favoured by periods of high rainfall followed by dry weather. A survey was made, at monthly intervals from January to June 1975, to try to determine l...

L-Methionine-DL-sulfoximine, a glutamate analog known to inhibit glutamine synthetase (GS) and glutamate synthase (GOGAT), allowed nitrogenase biosynthesis by Fratikia strain D11 in presence of NH4$. GS activity, detected in cell-free extracts of D1 1 , was higher in N2-fixing than in nonfixing conditions. These facts suggested that nitrogenase biosynthesis in Frankia was probably regulated by ...

We studied the metabolic fate of [carbonyl-14C]nicotinamide and [8-(14)C]adenine in segments taken from young and developing leaves, stem, hypocotyls, and roots of a shoot-root type emerging propagule of the mangrove plant Bruguiera gymnorrhiza. Thin-layer chromatography was used together with a bioimaging analyser system. During 4 h of incubation, incorporation of radioactivity from [carbonyl-...

To identify key genes in the regulation of salt tolerance in the mangrove plant Bruguiera gymnorhiza, transcriptome profiling in the lateral and main roots under conditions of salt stress was performed. Statistical analysis revealed that 175 and 403 of 11,997 genes shoewd significantly increased high expression in the lateral and main roots respectively. One hundred and sixty genes were up-regu...
