A novel compound, serinol phosphate, was identified in sugarcane (Saccharum officinarum) clone 51NG97. It was produced by an enzyme-mediated transamination of dihydroxyacetone phosphate with either alanine, glutamate, aspartate, or glutamine serving equally well as an amino donor. Some detectable phosphatase activity was present in crude leaf enzyme preparation that hydrolyzed serinol phosphate...

The phenolic acids found in graminaceous plant cellwalls are esters with sugars and lignin.1 ~3) Previously, we separated two feruloylated oligosaccharides from an enzymatic hydrolysate of the bagasse lignin-carbohydrate complex.4'5* As an extension of the structural elucidation of phenolic-acid-containing oligosaccharides, we now describe the isolation and identification of a new tetrasacchari...

Simultaneous quantitative analysis of 10 indole compounds, including indole-3-acetic acid (IAA, one of the most important naturally occurring auxins) and some of its metabolites, by high performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) after solid-phase extraction (SPE) was reported for the first time. The analysis was carried out using a reverse phas...

Endophytic bacteria were isolated from the stalks of sugarcane, Saccharum officinarum, growing in Papua New Guinea. Endophytic bacterial communities from extracted juice averaged 6x 10 cfu/ml, which is 25 times greater than the number of endophytic bacteria found in commercial varieties in South Africa. Sixty isolates, representing the different colony morphology types, were used for in vitro i...

DNA profiles of 40 sugarcane genotypes were constructed with 30 RAPD markers. Sugarcane genotypes of both Saccharum officinarum and S. barberi were included in this study. Multiple alleles were detected from each RAPD; there was a high level of polymorphism. On average, 7.93 alleles were produced per primer, giving a total of 238 alleles. The genetic distances between these genotypes were asses...
