1. Nutritional and bioactive exploration seeds of Ten Plant Species of Caatinga / ProspecÃÃo nutricional e bioativa de sementes de dez espÃcies vegetais da caatinga
A Caatinga possui uma vegetaÃÃo heterogÃnea cuja biodiversidade taxonÃmica conta com mais de 2.000 espÃcies de plantas. Dentre essas, cerca de 220 pertencem à famÃlia das leguminosas com 80 espÃcies endÃmicas, Ãnicas desse bioma. Muitas sÃo usadas para diversas finalidades de forma indiscriminada, reduzindo consideravelmente a diversidade e o nÃm

2. CARACTERIZAÇÃO QUÍMICA E DIGESTIBILIDADE IN VITRO DE LEGUMINOSAS FORRAGEIRAS TROPICAIS COM FOCO NO EFEITO DE COMPOSTOS FENÓLICOS E IDADE DA PLANTA. / CHEMICAL AND IN VITRO DIGESTIBILITY OF TROPICAL FORAGE LEGUMES FOCUSING ON THE EFFECT OF PHENOLIC COMPOUNDS AND PLANT AGE.
It were evaluated the gas production from tropical legumes with forage potential, including sun hemp (Crotalaria juncea), indian rattlebox (Crotalaria spectabilis), pigeon pea (Cajanus cajan), perennial horse gram (Macrotyloma axillare), cowage (Mucuna aterrina) wild groundnut (Calopogonium mucunoides) stylosanthes Campo Grande (Stylosantis sp .) and jack-be

3. Caracterização bioquímica e histo-estrutural de embriões de Inga vera Willd. Subsp. affinis (DC.) T.D. Penn. durante a maturação e após secagem / Biochemical, histological and structural characterization of Inga vera Wild. Subsp. Affinis (DC.) T.D. Penn. seeds during maturation and after drying
Inga vera Pennington produz sementes com alta sensibilidade à dessecação, o que dificulta seu armazenamento. Diversos mecanismos estão relacionados tolerância à dessecação, dentre eles o acúmulo de reservas insolúveis e de moléculas protetoras, redução do metabolismo e dobramento da parede celular. Desse modo, o objetivo deste trabalho foi anali

4. Lipopolysaccharide Profiles from Nodules as Markers of Bradyrhizobium Strains Nodulating Wild Legumes
To develop the use of electrophoretic lipopolysaccharide profiles for Bradyrhizobium strain identification, we studied the feasibility of using electrophoresis of whole legume nodule homogenates to obtain distinctive lipopolysaccharide profiles. The electrophoretic patterns were the same whether we used nodule extracts, bacteroids, or cultured bacteria as sa

5. A Nonsymbiotic Root Hair Tip Growth Phenotype in NORK-Mutated Legumes: Implications for Nodulation Factor–Induced Signaling and Formation of a Multifaceted Root Hair Pocket for Bacteria
The Medicago truncatula Does not Make Infections (DMI2) mutant is mutated in the nodulation receptor-like kinase, NORK. Here, we report that NORK-mutated legumes of three species show an enhanced touch response to experimental handling, which results in a nonsymbiotic root hair phenotype. When care is taken not to induce this response, DMI2 root hairs respon

6. Characterization and symbiotic importance of acidic extracellular polysaccharides of Rhizobium sp. strain GRH2 isolated from acacia nodules.
Rhizobium sp. wild-type strain GRH2 was originally isolated from root nodules of the leguminous tree Acacia cyanophylla and has a broad host range which includes herbaceous legumes, e.g., Trifolium spp. We examined the extracellular exopolysaccharides (EPSs) produced by strain GRH2 and found three independent glycosidic structures: a high-molecular-weight ac

7. Flavone-enhanced accumulation and symbiosis-related biological activity of a diglycosyl diacylglycerol membrane glycolipid from Rhizobium leguminosarum biovar trifolii.
Rhizobium leguminosarum bv. trifolii is the bacterial symbiont which induces nitrogen-fixing root nodules on the leguminous host, white clover (Trifolium repens L.). In this plant-microbe interaction, the host plant excretes a flavone, 4',7-dihydroxyflavone (DHF), which activates expression of modulation genes, enabling the bacterial symbiont to elicit vario

8. Nodule initiation elicited by noninfective mutants of Rhizobium phaseoli.
Rhizobium phaseoli CE106, CE110, and CE115, originally derived by transposon mutagenesis (Noel et al., J. Bacteriol. 158:149-155, 1984), induced the formation of uninfected root nodule-like swellings on bean (Phaseolus vulgaris). Bacteria densely colonized the root surface, and root hair curling and initiation of root cortical-cell divisions occurred normall

9. Beginnings of Village-Farming Communities in Southeastern Turkey
Since the end of World War II, much evidence has accrued of the primary phase of village-farming community life in Southwestern Asia, which began about 7000 B.C. The remains of (usually) several of the positively domesticated animals (dog, sheep, goat, pig) and plants (wheat, barley, legumes such as peas and lentils) assure us that these settlements were bas

10. Bradyrhizobium elkanii rtxC Gene Is Required for Expression of Symbiotic Phenotypes in the Final Step of Rhizobitoxine Biosynthesis
We disrupted the rtxC gene on the chromosome of Bradyrhizobium elkanii USDA94 by insertion of a nonpolar aph cartridge. The rtxC mutant, designated ΔrtxC, produced serinol and dihydrorhizobitoxine but no rhizobitoxine, both in culture and in planta. The introduction of cosmids harboring the rtxC gene into the ΔrtxC mutant complemented rhizobitoxine product

11. Zeolin. A New Recombinant Storage Protein Constructed Using Maize γ-Zein and Bean Phaseolin1
The major seed storage proteins of maize (Zea mays) and bean (Phaseolus vulgaris), zein and phaseolin, accumulate in the endoplasmic reticulum (ER) and in storage vacuoles, respectively. We show here that a chimeric protein composed of phaseolin and 89 amino acids of γ-zein, including the repeated and the Pro-rich domains, maintains the main characteristics

12. Bottlenecks for metabolic engineering of isoflavone glycoconjugates in Arabidopsis
In view of their perceived chemopreventive activities against hormone-dependent cancers, cardiovascular disease, and postmenopausal ailments, there is considerable interest in engineering plants to contain isoflavone phytoestrogens. However, attempts to date have only resulted in low levels of isoflavone accumulation in non-legumes. Introducing soybean isofl
