- Evidence for a Role for AtMYB2 in the Induction of the Arabidopsis Alcohol Dehydrogenase Gene (ADH1) by Low Oxygen...not survive even short periods of anaerobi- The Arabidopsis ADH1 GT-motif contains a potential osis (Okimoto et al. 1980). Myb binding site. Myb transcription factors bind to a Sequence elements in the promoter of the maize consensus sequence with an AAC central motif (59-T/ ADH1 gene, which are critical ~~~
- Potential Retroviruses in Plants: Tat1 Is Related to a Group of Arabidopsis thaliana Ty3/gypsy Retrotransposons That Encode Envelope-Like Proteins...retrotransposon features, including a primer binding site complementary to an A. thaliana asparagine tRNA and an open reading frame (ORF) with z44% amino acid sequence similarity to the gag protein of the Zea mays retrotransposon Zeon-1. Tat1 elements have large, polymorphic 39 noncoding regions that may contain ~~~
- Activation of Latent Transgenes in Arabidopsis Using a Hybrid Transcription Factor...lines were created containing test genes controlled by a synthetic promoter consisting of concatemeric copies of the cis-acting site recognized by GAL4 (UAS G) fused to a minimal promoter. The GAL4/C1 effector line was crossed to two lines containing a synthetic promoter/GUS fusion. Both histochemical ~~~
- Major Chromosomal Rearrangements Induced by T-DNA Transformation in Arabidopsis....4-kb deletion at this point, whereas chromosome 2 anking regions are located 40 cM apart on the bottom arm of chromosome 2. These results strongly suggest a reciprocal translocation between chromosomes 2 and 3, with the breakpoints located at the T-DNA insertion sites. The interchanged fragments ~~~
- Characterization of the Putative Transposase mRNA of Tag1, Which Is Ubiquitously Expressed in Arabidopsis and Can Be Induced by Agrobacterium-Mediated Transformation With dTag1 DNA...and comal. 1991; Warren et al. 1994; Essers and Kunze 1995; pared them to somatic and germinal excision rates of Grappin et al. 1996; Kempken and Kuck 1996). All mem- the element. We have also isolated and sequenced Tag1 bers of this family produce an 8-bp target site duplica- cDNA clones and found ~~~
- Molecular Organization of the 20S Proteasome Gene Family from Arabidopsis thaliana...as a hollow cylinder comprising four stacked rings with the catalytic sites located in the lumen. The two outer rings and the two inner rings are composed of seven different a and b polypeptides, respectively, giving an a7/b7/b7/a7 symmetric organization. Here we describe the molecular organization of the 20S ~~~
- Coordination of Phytochrome Levels in phyB Mutants of Arabidopsis as Revealed by Apoprotein-Specific Monoclonal Antibodies...al. 1987), from the XbaI site to the SstI site, with the polylinker from pGEM3 (Promega, Inc., Madison, WI). Subsequently,apoproteins were expressed in E. coli and puried, and the PHYB cDNA sequence (Sharrock and Quail 1989), frommAbs which selectively detected PHYB and PHYC were nucleotide 43 ~~~
- Members of the Arabidopsis Actin Gene Family Are Widely Dispersed in the Genome...to have evolved slowly, somal regions, from the nomadic duplication of se- at about 1% change per 50100 my (Hightower and quences to a new site, from polyploidization of a whole Meagher 1986; McDowell et al. 1996) and were used genome, or from the fusion of two diverged genomes to estimate the timing ~~~
- Detection of Deleterious Genotypes in Multigenerational Studies. I. Disruptions in Individual Arabidopsis Actin Genes.... The two members of these pairs diverged from MATERIALS AND METHODSa common ancestral gene only 3050 my ago. For example, the ACT2/ACT8 pair and the ACT4/ACT12 pair Plant lines with mutant actin alleles: For our rst set of are each highly divergent in synonymous nucleotide site experiments we identi ~~~
- Gene Silencing and Homology-Dependent Gene Silencing in Arabidopsis: Genetic Modifiers and DNA Methylation...result methylation of a restriction site in the promoter (Kilby in silencing of homologous endogenous genes. This et al. 1992). Two inactive homozygous inbred lines (E phenomenon is called cosuppression (Napoli et al. and G) were generated. Each contained the nopaline 1990; reviewed in Jorgensen 1995 ~~~
