1. A perfect functional marker for the gene of intermediate amylose content Wx-in in rice (Oryza sativa L.)
Abstract The amylose content (AC) of rice is a key determinant of the grain cooking and eating quality. The Waxy (Wx) gene, which encodes granule-bound starch synthase I (GBSSI), is the major gene controlling AC in rice. The A - C substitution in exon 6 (Ex6A/C) alters the amino acid codon from serine to tyrosine and is associated with intermediate-AC rice (

4. Desenvolvimento de painéis multiplex de marcadores microssatélites para seleção assistida para qualidade de grãos de arroz (Oryza sativa L.)
O sucesso de uma variedade de arroz depende cada vez mais da qualidade dos seus grãos. A culinária brasileira exige, em geral, variedades com grãos longos, finos e alta qualidade de características físico-químicas, resultando em grãos mais soltos após a cocção. Qualidade de grãos é uma característica complexa, controlada por vários genes. O ami

5. Diversidade de Carotenóides Antioxidantes em Frutos de Espécies de Solanum (seção Lycopersicon): Caracterização Via Cromatografia Líquida de Alta Resolução (CLAE) e Análise Filogenética do Gene Codificador da Enzima Licopeno-ß-ciclase / Diversity of Antioxidants Carotenoids in Fruits of Solanum (section Lycopersicon): Characterization Via High Performance Liquid Chromatography (HPLC) and Phylogenetic Analysis of The Lycopene-ß-cyclase Gene
O tomateiro (Solanum lycopersicum L.) apresenta um papel de destaque na dieta humana de diferentes etnias e regiões geográficas. Entre as estratégias para aumentar e/ou permitir um consumo adequado de nutrientes essenciais, destacam-se a introdução de alimentos ricos em carotenóides na dieta, além do melhoramento genético visando aumentar o teor pró

7. Comportamento de mutantes de endosperma de milho (zea mays L.) em relação ao fuzarium moniliforme Sheld
A comparative study involving 11 different endosperm mutants of maize and their correspondent normal counterparts was carried out to study the effect of endosperm mutant genes on pathogenicity of F. moniliforme. The following mutants were studied: Shrunken (sh), shrunken-2 (sh2), floury (fl), brittle (bt) brittle-2 (bt2), waxy (wx), dull (du), sugary (su), s

8. Comparison of Non-Mutant and Mutant Waxy Genes in Rice and Maize
The waxy gene, which is responsible for the synthesis of amylose in endosperm and pollen, is genetically well characterized in many grasses including maize and rice. Homology between the previously cloned maize waxy gene and the rice gene has facilitated our cloning of a 15-kb HindIII fragment that contains the entire rice gene. A comparison of the restricti

9. Evidence for the Inclusion of Controlling Elements within the Structural Gene at the Waxy Locus in Maize
Minimal limits for the structural gene at the waxy locus have been set by investigations of the protein product of the gene. An altered protein is produced by four of the waxy mutants including B3, a controlling-element mutation. All are similar to wild type in molecular weight as determined by electrophoresis in SDS acrylamide gels. At least three of the fi

10. Nonsense-Mediated Decay of Mutant waxy mRNA in Rice
Two rice (Oryza sativa) waxy mutations of the Japonica background were shown to contain approximately 20% of the fully spliced mRNA relative to the wild type. Sequencing analysis of the entire waxy genes of the two mutants revealed the presence of premature translation termination codons in exon 2 and exon 7. These results indicated that the lower accumulati

11. Waxy Chlamydomonas reinhardtii: monocellular algal mutants defective in amylose biosynthesis and granule-bound starch synthase activity accumulate a structurally modified amylopectin.
Amylose-defective mutants were selected after UV mutagenesis of Chlamydomonas reinhardtii cells. Two recessive nuclear alleles of the ST-2 gene led to the disappearance not only of amylose but also of a fraction of the amylopectin. Granule-bound starch synthase activities were markedly reduced in strains carrying either st-2-1 or st-2-2, as is the case for a
