    摘要: The present inventors have discovered that CAX1-like Hnull/Canull2 antiporter is essential for plant growth. Specifically, the inhibition of CAX1-like Hnull/Canull2 antiporter gene expression in plant seedlings results in reduced growth and abnormal development. Thus, CAX1-like Hnull/Canull2 antiporter 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 a CAX1-like Hnull/Canull2 antiporter in the presence and absence of a compound, where an alteration of CAX1-like Hnull/Canull2 antiporter activity in the presence of the compound indicates the compound as a candidate for a herbicide.

    摘要: The invention provides methods for detecting mutations in the human GCPII gene which affect the ability of an individual to hydrolyze terminal glutamates from dietary folates. Such individuals are at increased risk for conditions associated with hyperhomocyteinemia, in particular, cardiovascular disease, colon cancer, and altered cognition in the elderly, including Alzheimer's disease. In addition, pregnant women with low folate status are at increased risk of bearing children with neural tube defects and congenital heart defects. Individuals with these mutations can be screened and treated with supplementation of their diet with folic acid.
