Resolution and characterization of pro-B and pre-pro-B cell stages in normal mouse bone marrow
TLDR
Functional analysis demonstrates that the proliferative response to IL-7, an early B lineage growth factor, is restricted to S7+ stages and, furthermore, that an additional, cell contact-mediated signal is essential for survival of Fr. Expand
Nucleotide sequence of the T-DNA region from theA grobacterium tumefaciens octopine Ti plasmid pTi15955
TLDR
The complete nucleotide sequence of the transferred region of an octopine tumor inducing (Ti) plasmid from Agrobacterium tumefaciens (pTi15955) has been determined and it was revealed that recognition sites for 72 restriction endonucleases are present in the DNA sequence at least once. Expand
Fluorescent Amplified Fragment Length Polymorphism Analysis of Bacillus anthracis, Bacillus cereus, and Bacillus thuringiensis Isolates
TLDR
Phylogenetic analysis of AFLP data revealed extensive diversity within B. thuringiensis and B. anthracis isolates, which suggests that phenotypic traits used to distinguish between these two species do not reflect the genomic content of the different isolates and that horizontal gene transfer plays an important role in establishing the phenotype of each of these microbes.

Accumulation of 15-Kilodalton Zein in Novel Protein Bodies in Transgenic Tobacco
TLDR
The results demonstrate that the 15-kD zein protein is stable not only in seeds but in all nonseed tissues tested, whereas the [beta]-phaseolin protein accumulated only in mid- and postmaturation seeds. Expand
Genetic engineering ruminal stable high methionine protein in the foliage of alfalfa
TLDR
The results demonstrate that as in tobacco both the β- and the δ-zeins accumulate in the leaves of alfalfa and that the co-expression of the two zein genes has a stabilizing effect on the τ-zein, however, the level of accumulation of the zeins in al falfa leaves is not high enough to make a significant change in the methionine levels.

Naturally occurring mutations in the human 5-lipoxygenase gene promoter that modify transcription factor binding and reporter gene transcription.
TLDR
Electrophoretic mobility shift assays demonstrated the capacity of wild type and mutant transcription factor binding regions to bind nuclear extracts from human umbilical vein endothelial cells (HUVECs) and are consistent with a family of mutations in the 5-LO gene that can modify reporter gene transcription possibly through differences in Sp1 and Egr-1 transactivation. Expand
Coexpression of the maize delta-zein and beta-zein genes results in stable accumulation of delta-zein in endoplasmic reticulum-derived protein bodies formed by beta-zein.
TLDR
It is concluded that delta-ZEin interacts with beta-zein and that the interaction has a stabilizing effect on delta-ze in plants and on zein-specific ER-derived protein bodies. Expand
Defective expression of p56lck in an infant with severe combined immunodeficiency.
TLDR
Data suggest that a deficiency in p56lck expression can produce a SCID phenotype in humans, and this decrease was associated with the presence of an alternatively spliced lck transcript lacking the exon 7 kinase encoding domain. Expand
Genetic Analysis of a Novel Xylella fastidiosa Subspecies Found in the Southwestern United States
TLDR
Analysis of isolates associated with infected chitalpa trees in the Southwest are a highly related group that is distinct from the four previously defined taxons X. fastidiosa (piercei), X. multiplex, X. sandyi, and X. pauca. Expand
Identification of a murine pan-T cell antigen which is also expressed during the terminal phases of B cell differentiation.
TLDR
A new rat anti-mouse mAb, designated S7, reacts with all Thy-1.2-positive cells and all granulocytic cells in the marrow and will probably be useful in studies aimed at subdividing the later stages of the B cell maturation process. Expand
