摘要:
Proteins from the genus Photorhabdus are toxic to insects upon exposure. Photorhabdus luminescens (formerly Xenorhabdus luminescens) have been found in mammalian clinical samples and as a bacterial symbiont of entomopathogenic nematodes of genus Heterorhabditis. These protein toxins can be applied to, or genetically engineered into, insect larvae food and plants for insect control.

The present invention relates to the fields of agriculture, plant breeding or genetic engineering for plants with increased yield, crop forecasting and crop management. In particular, the methods herein describe novel methods of predicting a plant's yield through the measurement of specific metabolites either individually or in combination with one another in a specific plant reproductive tissue. The plant predictive methods described herein may be used to predict yield of plant populations as well as allow for more efficient crop management practices (e.g. amount and timing of chemical applications or amount of irrigation water applied to a field).
摘要:
The present invention provides various biomarkers for hepatotoxicity and various methods of using the biomarkers Some of the biomarkers within the scope of this invention are cholate, glycochenodeoxycholate, glycocholate, taurine, 3-hyroxy-2-ethylpropionate, 4-imidazoleacetate, tyramine, anthranilate, 2′-deoxycytidine, N-acetyl aspartate (NAA), beta-hydroxy-hexanoate, and sarcosine (N-methylglycine) The methods of using the biomarkers include exposing a first hepatocyte culture to a test agent and comparing the levels of the one or more biomarkers obtained in the first hepatocyte culture to the levels of the one or more biomarkers obtained in a second hepatocyte culture without the test agent, where differential levels of the one or more biomarkers in the first hepatocyte culture as compared to the levels in the second hepatocyte culture is indicative of the test agent being a hepatotoxicant.

摘要:
The present inventors have discovered that serine acetyltransferase (SAT) is essential for plant growth. Specifically, the inhibition of SAT gene expression in plant seedlings results in reduced growth and altered pigmentation. Thus, SAT is useful as a target for the identification of herbicides. Accordingly, the present invention provides methods for the identification of herbicides by measuring the activity of an SAT in the presence and absence of a compound, wherein an alteration of SAT activity in the presence of the compound indicates the compound as a candidate for a herbicide.

In the methods of the present invention, the change in absorbance of an obtusifoliol 14α-demethylase (OBT-DM) enzyme upon binding of an inhibitor is used to advantage for the identification of inhibitors of OBT-DM activity. Rather than measuring the absorbance of an OBT-DM/inhibitor complex over a spectrum of wavelengths as described previously, the present invention discloses methods for identifying type II inhibitors of OBT-DM by monitoring the absorbance only at 413 nm and 432 nm. The methods of the invention enable the concurrent testing of multiple compounds using a high throughput format such as with 96- or 384-well plates. The OBT-DM polypeptides of the invention include plant, fungal and human OBT-DM polypeptides, and in particular, Arabidopsis thaliana OBT-DM polypeptide
