1. Isoflavone, anthocyanin, and fatty acid contents of vegetable-type soybean grains at different maturity stages
Resumo: O objetivo deste trabalho foi determinar os teores de óleo, proteína, ácidos graxos, isoflavonas e antocianinas, em grãos de soja de diferentes linhagens e estádios de maturação. Foram feitas avaliações quantos aos perfis químicos das linhagens com tegumento preto (BRM09-50995) e amarelo (BRM11-51428 e BRM08-50643), colhidas nos estágios d

2. Physicochemical and antioxidative properties of black, brown and red rice varieties of northern Thailand
Rice, the seed of Oryza species, is the major cereal crop in most of the developing countries. Nearly 95% of global rice production is done in Asian countries, and about half of the world’s population consumes it. Some speciality rices are not commonly consumed. Colored rice is one of such variety. In these varieties, high amounts of anthocyanin pigment ar

3. Viability and vigor of jamun (Syzygium cumini) seeds
Jamun (Syzygium cumini L. Skeels) (Black plum, Damson plum) fruits weigh between 2-5 g at maturity. Fresh seeds represented 20-80% of the total fruit weight; the seed coat and cotyledons contributed 6% and 94% to the total seed weight respectively, while the weight of the embryonic axis was insignificant. Only the embryonic axis stained with Tetrazolium, not

4. Ciclo de vida, estrutura foliar e variações morfoanatômicas influenciadas por diferenças ambientais para Victoria amazonica (POEPP.) J.C. Sowerby (Nymphaeaceae) na Amazônia Central
The Amazon floodplains are specific ecosystems with high biodiversity and endemism, divided in varzeas, white fertile waters, and Igapos with poor and acid waters, black or clear, and mixed waters between the two typologies. This study aimed to characterize morphologically and anatomically leaf structure, germination and life cycle of Victoria amazonica (Poe

5. Genetic mapping of soybean seed and in silico analysis of the microssatelites markers / Mapeamento de caracteres do tegumento da semente de soja e análise in silico dos marcadores microssatélites
The use of quality seeds is preponderant to obtain productive success in farming. Several are the factors that influence in the quality of seeds, and among these the flotations can be mentioned in the humidity of seeds and even the use of inadequate techniques in the crop. The coat of soybean seeds is the responsible for the protection of the embryo, therefo

6. Caracterização morfo-fisiológica e identificação de fragmentos de cDNA diferencialmente expressos de tegumentos de sementes de soja com permeabilidade contrastante / Morpho-physiologic characterization and identification of fragments of cDNA distinguishing expressed in soybean seed coat with contrasting permeability
Some works have reported the existence of contrasting soybean genotypes for physiological quality of seeds. There are such differences because of the presence of seeds with total or partial impermeability for water absorption into the coat that make them less susceptible to mechanical damages, weather adversities, deterioration by humidity and pathogen occur

7. Pigmented Soybean (Glycine max) Seed Coats Accumulate Proanthocyanidins during Development.
The dominant I gene inhibits accumulation of anthocyanin pigments in the epidermal layer of soybean (Glycine max) seed coats. Seed-coat color is also influenced by the R locus and by the pubescence color alleles (T, tawny; t, gray). Protein and RNA from cultivars with black (i,R,T) and brown (i,r,T) seed coats are difficult to extract. To determine the natur

8. A soybean cell wall protein is affected by seed color genotype.
The dominant I gene inhibits accumulation of anthocyanin pigments in epidermal cells of the soybean seed coat. We compared saline-soluble proteins extracted from developing seed coats and identified a 35-kilodalton protein that was abundant in Richland (genotype I/I, yellow) and much reduced in an isogenic mutant line T157 (genotype i/i, imperfect black seed

9. Chalcone synthase mRNA and activity are reduced in yellow soybean seed coats with dominant I alleles.
The seed of all wild Glycine accessions have black or brown pigments because of the homozygous recessive i allele in combination with alleles at the R and T loci. In contrast, nearly all commercial soybean (Glycine max) varieties are yellow due to the presence of a dominant allele of the I locus (either I or i) that inhibits pigmentation in the seed coats. S

10. Tissue-Specific Gene Silencing Mediated by a Naturally Occurring Chalcone Synthase Gene Cluster in Glycine maxW⃞
Chalcone synthase, a key regulatory enzyme in the flavonoid pathway, constitutes an eight-member gene family in Glycine max (soybean). Three of the chalcone synthase (CHS) gene family members are arranged as inverted repeats in a 10-kb region, corresponding to the I locus (inhibitor). Spontaneous mutations of a dominant allele (I or ii) to a recessive allele

11. Inheritance and Organization of Glycinin Genes in Soybean.
Five genes (Gy1, through Gy5) encode most of the subunits that are assembled into glycinin, a predominant seed storage protein found in soybeans. Restriction fragment length polymorphisms are described that identify four of these five genes (Gy1/Gy2, Gy3, and Gy5). The fifth gene (Gy4) is characterized by two alleles, one of which (gy4) causes absence of the
