Journal ArticleDOI
Variation in seed protein digestion of different pea (Pisum sativum L.) genotypes by cecectomized broiler chickens: 2. Relation between in vivo protein digestibility and pea seed characteristics, and identification of resistant pea polypeptides
Irène Gabriel,Laurence Quillien,F. Cassecuelle,Pascal Marget,Hervé Juin,Michel Lessire,Bernard Sève,Gérard Duc,Judith Burstin +8 more
TL;DR: The average amino acid digestibility (apparent and true) and endogenous amino acid excretion were related with pea diet characteristics (protein composition, carbohydrate composition and TI activity) which allowed to precise which of the diet characteristics affect protein digestibility and endogenous excretion.
Journal ArticleDOI
Note on the presence of the sym-1 gene in Vicia faba hampering its symbiosis with Rhizobium leguminosarum
Gérard Duc,Jean Picard +1 more
TL;DR: A symbiotically defective mutant in Vicia faba is described, controlled by a recessive gene named sym-1, which can be either Fix+ Nod- or Nod-, depending on the strain of Rhizobium.
Journal ArticleDOI
Specificity of the Rhizobium-legume symbiosis obtained after mutagenesis in pea (Pisum sativum L.).
M. Sagan,A. Messager,Gérard Duc +2 more
TL;DR: Within a set of 13 induced symbiotic pea (Pisum sativum L.) mutants, two distinct mutated genes sym25 and sym26, selected for ineffective nodulation have been counteracted in their effect by Rhizobium strains 254 and 94 respectively, thereby establishing an N2 -fixing symbiosis.
Journal ArticleDOI
Mitochondrial plasmid-like molecules in fertile and male sterile Vicia faba L.
TL;DR: Biochemical analysis and electron microscopy showed that mitochondria of both the fertile and the male sterile 350 and 447 cytoplasms of Vicia faba contain two small supercoiled DNA molecules of mean length of 1 700 and 1 420 base pairs in addition to the main mitochondrial DNA of high molecular weight.
Journal ArticleDOI
Mutagenesis of faba bean (Vicia faba L.) and the identification of five different genes controlling no nodulation, ineffective nodulation or supernodulation
TL;DR: Grafting experiments showed that the (Nod+Fix−) and (nod−) phenotypes were both under root genotype control and that the(Nod++, Nts) phenotype was under shoot genotypes control.
