We report the identification and characterization of a low tocopherol Arabidopsis thaliana mutant, vitamin E pathway gene5-1 (vte5-1), with seed tocopherol levels reduced to 20% of the wild type. Map-based identification of the responsible mutation identified a G-->A transition, resulting in the introduction of a stop codon in At5g04490, a previously(More)
We characterized an amphioxus NK-2 homeobox gene (AmphiNk2-1), a homologue of vertebrate Nkx2-1, which is involved in the development of the central nervous system and thyroid gland. At the early neurula stage of amphioxus, AmphiNk2-1 expression is first detected medially in the neural plate. By the mid-neurula stage, expression is localized ventrally in(More)
The genome of amphioxus includes AmphiNk2-2, the first gene of the NK2 homeobox class to be demonstrated in any invertebrate deuterostome. AmphiNk2-2 encodes a protein with a TN domain, homeodomain, and NK2-specific domain; on the basis of amino acid identities in these conserved regions, AmphiNk2-2 is a homolog of Drosophila vnd and vertebrate Nkx2-2.(More)
In an effort to isolate genes required for heart development and to further our understanding of cardiac specification at the molecular level, we screened PlacZ enhancer trap lines for expression in the Drosophila heart. One of the lines generated in this screen, designated B2-2-15, was particularly interesting because of its early pattern of expression in(More)
The present study provides an assessment of the compositional diversity in maize B73 hybrids derived both from the Nested Association Mapping (NAM) founder lines and from a diverse collection of landrace accessions from North and South America. The NAM founders represent a key population of publicly available lines that are used extensively in the maize(More)
