1. Análise da via de regulação gênica do miRNA156/SPL na brotação lateral e caracterização molecular do processo de emergência da gema axilar de cana de açucar / Analysis of the role(s) of the miRNA156/SPL pathway on branching/tillering and molecular characterization of sugarcane lateral bud outgrowth
Sugarcane is an economically important biofuel crop that recently has become a target for improvement of sustainable biomaterial production due to its high biomass productivity and built-in containment features. Therefore, studies aiming to improve the production of biomass per area are among the most important issues in sugarcane production. Plant biomass i

2. Identificação e isolamento de proteinas que se ligam aos telomeros de Leishmania (L.) amazonensis / Identification and purification of Leishmania (L.) amazonensis telomeric proteins
A leishmaniose é uma doença parasitária que foi considerada pela Organização Mundial de Saúde como uma doença de Categoria 1, pois para a mesma não existem formas de controle, diagnóstico ou terapia eficientes. Os parasitas do gênero Leishmania (família Trypanosomatidae) são agentes etiológicos da leishmaniose e possuem cromossomos lineares com

3. Sequence-specific DNA recognition by the myb-like domain of the human telomere binding protein TRF1: a model for the protein-DNA complex.
Telomeres consist of tandem arrays of short G-rich sequence motifs packaged by specific DNA binding proteins. In humans the double-stranded telomeric TTAGGG repeats are specifically bound by TRF1 and TRF2. Although telomere binding proteins from evolutionarily distant species are not sequence homologues, they share a Myb-like DNA binding motif. Here we have

4. Floral asymmetry involves an interplay between TCP and MYB transcription factors in Antirrhinum
To understand how genes control floral asymmetry, we have isolated and analyzed the role of the RADIALIS (RAD) gene in Antirrhinum. We show that the RAD gene encodes a small MYB-like protein that is specifically expressed in the dorsal region of developing flowers. RAD has a single MYB-like domain that is closely related to one of the two MYB-like domains of

5. A novel DNA binding protein with homology to Myb oncoproteins containing only one repeat can function as a transcriptional activator.
A cDNA clone encoding a novel Myb-related protein, designated MybSt1, was isolated from a potato cDNA expression library by South Western screening using the CaMV 35S promoter domain A as a probe. Sequence comparison shows a small region with some homology to the highly conserved DNA binding domain of the c-myb proto-oncogene consisting of three imperfect re

6. The Maize Single myb histone 1 Gene, Smh1, Belongs to a Novel Gene Family and Encodes a Protein That Binds Telomere DNA Repeats in Vitro1[w]
We screened maize (Zea mays) cDNAs for sequences similar to the single myb-like DNA-binding domain of known telomeric complex proteins. We identified, cloned, and sequenced five full-length cDNAs representing a novel gene family, and we describe the analysis of one of them, the gene Single myb histone 1 (Smh1). The Smh1 gene encodes a small, basic protein wi

7. Adf-1 Is a Nonmodular Transcription Factor That Contains a TAF-Binding Myb-Like Motif
Adf-1 is an essential Drosophila melanogaster sequence-specific transactivator that binds the promoters of a diverse group of genes. We have performed a comprehensive mapping of the functional domains of Adf-1 to study the role of transactivators in the process of gene activation. Using a series of clustered point mutations and small deletions we have identi

8. Alternatively spliced products of the maize P gene encode proteins with homology to the DNA-binding domain of myb-like transcription factors.
The Zea mays P gene has been postulated to regulate the biosynthetic pathway of a flavonoid-derived pigment in certain floral tissues [Styles, E. D. & Ceska, O. (1977) Can. J. Genet. Cytol. 19, 289-302]. We have characterized two P transcripts that are alternatively spliced at their 3' ends. One message of 1802 nucleotides encodes a 43.7-kDa protein with an

9. G2/M-Phase–Specific Transcription during the Plant Cell Cycle Is Mediated by c-Myb–Like Transcription Factors
Plant B-type cyclin genes are expressed specifically in late G2- and M-phases during the cell cycle. Their promoters contain a common cis-acting element, called the MSA (M-specific activator) element, that is necessary and sufficient for periodic promoter activation. This motif also is present in the tobacco kinesin-like protein gene NACK1, which is expresse

10. A-myb is expressed in bovine vascular smooth muscle cells during the late G1-to-S phase transition and cooperates with c-myc to mediate progression to S phase.
The Myb family of transcription factors is defined by homology within the DNA binding domain and includes c-Myb, A-Myb, and B-Myb. The protein products of the myb genes all bind the Myb-binding site (MBS) [YG(A/G)C(A/C/G)GTT(G/A)]. A-myb has been found to display a limited pattern of expression. Here we report that bovine aortic smooth muscle cells (SMCs) ex

11. The Arabidopsis GAMYB-Like Genes, MYB33 and MYB65, Are MicroRNA-Regulated Genes That Redundantly Facilitate Anther Development
The functions of the vast majority of genes encoding R2R3 MYB domain proteins remain unknown. The closely related MYB33 and MYB65 genes of Arabidopsis thaliana have high sequence similarity to the barley (Hordeum vulgare) GAMYB gene. T-DNA insertional mutants were isolated for both genes, and a myb33 myb65 double mutant was defective in anther development. I

12. In Vivo Analysis of Functional Regions within Yeast Rap1p
We have analyzed the in vivo importance of different regions of Rap1p, a yeast transcriptional regulator and telomere binding protein. A yeast strain (SCR101) containing a regulatable RAP1 gene was used to test functional complementation by a range of Rap1p derivatives. These experiments demonstrated that the C terminus of the protein, containing the putativ
