1. Expressão do gene ASYMMETRIC LEAVES1 (AS1) em explantes radiculares de Passiflora edulis Sims e organogênese in vitro em Passiflora setacea D.C. (Passifloraceae) / Expression of the gene ASYMMETRIC LEAVES1 (AS1) in root explants from Passiflora edulis Sims and organogenesis in vitro in Passiflora setacea D.C. (Passifloraceae)
O presente estudo teve como objetivos caracterizar a expressão do gene ASYMMETRIC LEAVES1 (AS1), via hibridização in situ, durante a regeneração in vitro de segmentos radiculares de Passiflora edulis Sims, espécie comercialmente cultivada, e estabelecer um protocolo reproduzível via organogênese in vitro em Passiflora setacea, espécie silvestre.

2. Sintese quimioenzimatica de (-)- serricornina e (+)- sitofilure
Chiral alcohols are versatile and convenient building blocks in the synthesis of biologically important compounds. Asymmetric reduction of b-keto esters by Baker s yeast (S. cerevisiae) has been widely used to obtain chiral alcohols because of simplicity, cheapness and enantioselectivity. However, the optical purities and the yields of these compounds are of

3. Asymmetric Auxin Response Precedes Asymmetric Growth and Differentiation of asymmetric leaf1 and asymmetric leaf2 Arabidopsis Leaves
We have analyzed the development of leaf shape and vascular pattern in leaves mutant for ASYMMETRIC LEAVES1 (AS1) or AS2 and compared the timing of developmental landmarks to cellular response to auxin, as measured by expression of the DR5:β-glucuronidase (GUS) transgene and to cell division, as measured by expression of the cycB1:GUS transgene. We found th

4. Conservation and molecular dissection of ROUGH SHEATH2 and ASYMMETRIC LEAVES1 function in leaf development
Maize ROUGH SHEATH2 (RS2) and Arabidopsis ASYMMETRIC LEAVES1 (AS1) are orthologous Myb-related genes required for leaf development and act as negative regulators of class 1 KNOTTED1-like homeobox (KNOX) genes in leaf primordia. Expression of RS2 in Arabidopsis fully complements as1 leaf phenotypes and represses the expression of the KNOX gene KNAT1 in

5. The bromodomain protein GTE6 controls leaf development in Arabidopsis by histone acetylation at ASYMMETRIC LEAVES1
The transition from the juvenile to the mature phase during vegetative development in plants is characterized by changes in leaf shape. We show that GENERAL TRANSCRIPTION FACTOR GROUP E6 (GTE6) regulates differences in leaf patterning between juvenile and mature leaves in Arabidopsis. GTE6 encodes a novel small bromodomain-containing protein unique to plants

6. The Putative RNA-Dependent RNA Polymerase RDR6 Acts Synergistically with ASYMMETRIC LEAVES1 and 2 to Repress BREVIPEDICELLUS and MicroRNA165/166 in Arabidopsis Leaf DevelopmentW⃞
The Arabidopsis thaliana ASYMMETRIC LEAVES1 (AS1) and AS2 genes are important for repressing class I KNOTTED1-like homeobox (KNOX) genes and specifying leaf adaxial identity in leaf development. RNA-dependent RNA polymerases (RdRPs) are critical for posttranscriptional and transcriptional gene silencing in eukaryotes; however, very little is known about thei

7. Heterodimerization between light-regulated and ubiquitously expressed Arabidopsis GBF bZIP proteins.
The promoters of a variety of plant genes are characterized by the presence of a G-box (CCACGTGG) or closely related DNA motifs. These genes often exhibit quite diverse expression characteristics and in many cases the G-box sequence has been demonstrated to be essential for expression. The G-box of the Arabidopsis rbcS-1A gene is bound by a protein, GBF, ide

8. Crown rootless1, Which Is Essential for Crown Root Formation in Rice, Is a Target of an AUXIN RESPONSE FACTOR in Auxin SignalingW⃞
Although the importance of auxin in root development is well known, the molecular mechanisms involved are still unknown. We characterized a rice (Oryza sativa) mutant defective in crown root formation, crown rootless1 (crl1). The crl1 mutant showed additional auxin-related abnormal phenotypic traits in the roots, such as decreased lateral root number, auxin

9. Rapid Array Mapping of Circadian Clock and Developmental Mutations in Arabidopsis1
Classical forward genetics, the identification of genes responsible for mutant phenotypes, remains an important part of functional characterization of the genome. With the advent of extensive genome sequence, phenotyping and genotyping remain the critical limiting variables in the process of map-based cloning. Here, we reduce the genotyping problem by hybrid

10. BLADE-ON-PETIOLE–Dependent Signaling Controls Leaf and Floral Patterning in Arabidopsis
NONEXPRESSOR OF PR GENES1 (NPR1) is a key regulator of the plant defense response known as systemic acquired resistance. Accumulation of the signal molecule salicylic acid (SA) leads to a change in intracellular redox potential, enabling NPR1 to enter the nucleus and interact with TGACG sequence–specific binding protein (TGA) transcription factors, which i

11. External reflection absorption infrared spectroscopy study of lung surfactant proteins SP-B and SP-C in phospholipid monolayers at the air/water interface.
The interactions of the hydrophobic pulmonary surfactant proteins SP-B and SP-C with 1,2-dipalmitoylphosphatidylcholine in mixed, spread monolayer films have been studied in situ at the air/water interface with the technique of external reflection absorption infrared spectroscopy (IRRAS). SP-C has a mostly alpha-helical secondary structure both in the pure s

12. X-ray structure determination at 2.6-A resolution of a lipoate-containing protein: the H-protein of the glycine decarboxylase complex from pea leaves.
H-protein, a lipoic acid-containing protein of the glycine decarboxylase (EC 1.4.4.2) complex from pea (Pisum sativum) was crystallized from ammonium sulfate solution at pH 5.2 in space group P3(1)21. The x-ray crystal structure was determined to 2.6-A resolution by multiple isomorphous replacement techniques. The structure was refined to an R value of 23% f
