The diamondback moth, Plutella xylostella (L.), is a major pest responsible for destroying cabbage and other Brassica vegetable crops. A moth-resistant line was studied by comparing its metabolite profiles with those of susceptible cabbage. Fourier transform infrared spectroscopy analysis revealed that carbohydrates, aromatic compounds, amides were the factors distinguished resistant genotypes. Gas chromatography-time-of-flight mass spectrometry profiled 46 metabolites, including 19 amino...

For the diagnosis of soil contamination, it is necessary to accurately understand distribution pollutants in survey site. However, since practically impossible investigate all observable points site, concentration site predicted through a spatial prediction model based on data obtained from some selected due nature data, size often insufficient, which can greatly reduce accuracy prediction. Therefore, this study, solve problem, we propose Bayesian penalized spline that predicts contaminants...
