The multiple-stress responsive plastid sigma factor, SIG5, directs activation of the psbD blue light-responsive promoter (BLRP) in Arabidopsis thaliana.
Transcription in higher plant plastids is performed by two types of RNA polymerases called NEP and PEP, and expression of photosynthesis genes in chloroplasts is largely dependent on PEP, aExpand

Three new nuclear genes, sigD, sigE and sigF, encoding putative plastid RNA polymerase σ factors in Arabidopsis thaliana
Three new nuclear genes (sigD, sigE and sigF) of Arabidopsis thaliana, encoding putative plastid RNA polymerase σ factors, were identified and analyzed. Phylogenetic analysis revealed that higherExpand

An Arabidopsis sigma factor (SIG2)-dependent expression of plastid-encoded tRNAs in chloroplasts.
A eubacteria-type RNA polymerase (PEP) plays crucial roles for chloroplast development in higher plants. The core subunits are encoded on plastid DNA (rpo genes) while the regulatory sigma factorsExpand

DNA Microarray Analysis of Plastid Gene Expression in an Arabidopsis Mutant Deficient in a Plastid Transcription Factor Sigma, SIG2
The plastid genome of higher plants contains more than one hundred genes for photosynthesis, gene expression, and other processes. Plastid transcription is done by two types of RNA polymerase, PEPExpand

Chloroplast targeting, distribution and transcriptional fluctuation of AtMinD1, a Eubacteria-type factor critical for chloroplast division.
In Arabidopsis thaliana, a mature mesophyll cell contains approximately 100 chloroplasts. Although 12 arc mutants (accumulation and replication of chloroplasts) and two chloroplast division genesExpand

Usefulness of double gene construct for rapid identification of transgenic mice exhibiting tissue‐specific gene expression
Identification of transgenics still requires PCR and genomic Southern blot hybridization of genomic DNA isolated from tail pieces. Furthermore, identification of transgene‐expressing transgenicsExpand

Chloroplast ribosome release factor 1 (AtcpRF1) is essential for chloroplast development
To study the functions of nuclear genes involved in chloroplast development, we systematically analyzed albino and pale green Arabidopsis thaliana mutants by use of the Activator/Dissociation (Ac/Ds)Expand

Prolonged survival of mouse epididymal spermatozoa stored at room temperature
Summary: The viability and fertility of isolated mouse epididymal spermatozoa kept for up to 7 days at various temperatures (4°C, 22°C, and 37°C) were determined. Spermatozoa kept for 3 days at 22°CExpand

Specific reactivity of human monoclonal antibody AE6F4 against cancer cells in tissues and sputa from lung cancer patients.
In vitro immunization of normal human peripheral lymphocytes by the co-cultivation with A549 cells (a human lung adenocarcinoma cell line), followed by the hybridization with the partner cell lineExpand

Production of recombinant human monoclonal antibody using ras-amplified BHK-21 cells in a protein-free medium.
A ras oncogene-amplified recombinant BHK-21 cell line (ras-rBHK-IgG) has been established, and was shown to hyperproduce the recombinant IgG chimeric human monoclonal antibody (hMAb) AE6F4, whichExpand
