Effect of Two Cowpea (Vigna unguiculata) Fodder Cultivars as Supplements on Voluntary Intake; Milk Yield and Manure Production of Bunaji Cows JARTS
Akinlade, J. A.; Smith, J. W.; Raji, A. M.; Busari, A. A.; Adekunle, I. O.; Adewumi, M. K..
The feeding value of fodder from two cowpea cultivars to a basal maize stover diet was investigated using fifteen lactating White Fulani (Zebu) cows. The two cultivars were IT-716 and 994-DP. Diet was constituted as 50g DM/kg live weight and each of the cultivars was supplemented at 50% of the daily dry matter requirement of individual animals. The experimental design was a complete randomize. The parameters measured included feed intake, milk yield and composition and manure production. In a separate trial, dry matter degradation of the fodder was assessed. There were no significant differences in dry matter intake of the supplements. However, the dry matter intake of stover in the control diet was higher than those on the supplemented groups. The milk...

Factors influencing electroporation-mediated gene transfer to Stylosanthes guianensis (Aubl.) Sw. protoplasts Genet. Mol. Biol.
Quecini,V.M.; Oliveira,C.A. de; Alves,A.C.; Vieira,M.L.C..
In order to develop a high-efficiency and reproducible transformation protocol for Stylosanthes guianensis we assessed the biological and physical parameters affecting plant electroporation protoplasts. Energy input, as combinations of electric field strengths discharged by different capacitors, electroporation buffer and DNA form were evaluated. Transformation efficiency was assayed in vivo as transient reporter gene expression, using the GFP-coding gene mgfp5 driven by a CaMV 35S constitutive promoter. Energy input and electric field strength had a critical influence on transgene expression with higher transformation levels being achieved with 250 V.cm-1 discharged by 900 and 1000 muF capacitors. Linear plasmid DNA, the absence of chloride and the...

Morphoagronomic variation in natural populations of Trifolium riograndense (Burkart) Scientia Agricola
Conterato,Ionara Fatima; Dall'Agnol,Miguel; Schifino-Wittmann,Maria Teresa; Montardo,Daniel Portela; Pontalti,Gabriel Colombo; Almeida,Danielle.
Several species of Trifolium are widely cultivated as forage for animals and green manure. This work aimed to characterize and estimate through morphological and agronomic traits the genetic diversity of natural populations of T. riograndense, an important forage legume from native pastures of the state of Rio Grande do Sul, Brazil. Plant height and diameter, number of primary and secondary stolons, stolon length, number of nodes per primary stolon, internode length, primary stolon diameter, leaf area, petiole length and dry matter production were analyzed in 29 accessions. The first five attributes and dry matter production were evaluated twice. A broad phenotypic variability was observed for almost all characteristics. Positive correlations occurred...

Plant regeneration from proroplasts of alfalfa (Medicago sativa) via somatic embryogenesis Scientia Agricola
Monteiro,Mariza; Appezzato-da-Glória,Beatriz; Valarini,Maria José; Oliveira,Carlos Alberto de; Vieira,Maria Lucia Carneiro.
Alfalfa is one of the most frequently studied species from the production of tissue culture-derived embryos point of view. In this study, five alfalfa cultivars were analyzed with reference to their ability to regenerate plants from protoplast cultures via somatic embryogenesis. Plant regeneration from leaf-derived protoplasts isolated from the cultivar Rangelander was achieved using a protocol defined for alfalfa cell suspension-derived embryogenesis. Because of its high efficiency, this procedure is recommended for protoplast electroporation-mediated genetic transformation of alfalfa.

Transient gene expression in electroporated intact tissues of Stylosanthes guianensis (Aubl.) Sw. Scientia Agricola
Quecini,Vera Maria; Vieira,Maria Lúcia Carneiro.
Genetic transformation though protoplast electroporation has been established for commercially important plant species. In this work, explant sources, electric field strengths, electroporation buffers, DNA forms and osmotic pretreatment were assayed in order to optimize transient reporter gene expression in electroporated tissues of Stylosanthes guianensis, a tropical forage legume. Higher transformation rates were obtained employing cotyledonary explants and an electric field strength of 250 V cm-1. Linear plasmid DNA, chloridefree electroporation buffer and osmotic pretreatment with 1.6 mol L-1 mannitol also improved transient transformation but non-significantly. Transgene specific PCR amplification was employed to prove the transformed status of the...
