Mutation in Eu3 eliminates activity of both soybean ureases, the embryo-specific (encoded by Eu1) and the tissue-ubiquitous (encoded by Eu4). eu3-e1 is a completely recessive null allele. Eu3-e3 is a semi-dominant specifying 0.1% wild-type urease activity in the homozygous state and 5-10% as a heterozygote (Meyer-Bothling et al. 1987). Antibodies to plant(More)
Presented here is the complete genome sequence of Thiomicrospira crunogena XCL-2, representative of ubiquitous chemolithoautotrophic sulfur-oxidizing bacteria isolated from deep-sea hydrothermal vents. This gammaproteobacterium has a single chromosome (2,427,734 base pairs), and its genome illustrates many of the adaptations that have enabled it to thrive(More)

Embedded assessments, tasks within the context of instruction, can serve as important tools for improving teaching and learning. In this article, we report on the assessment design principles and a nine-step development model that guided the construction of innovative embedded assessments. Using multiple sources of data-expert reviews, a conceptual test(More)
