Symbiotic Tissue Degradation Pattern in the Ineffective Nodules of Three Nodulation Mutants of Pea (Pisum sativum L.)
Abstract Three symbiotic mutants of pea ( Pisum sativum L.) forming ineffective nodules were investigated for aberrations in nodule structure using light and transmission electron microscopy. TheExpand

On the efficiency of legume supernodulating mutants
The supernodulating mutants of legumes lack the internal regulation of the number of symbiotic root nodules that harbour N2-fixing nodule bacteria. On one hand, these mutants represent an efficientExpand

Effect of exogenous flavonoids on nodulation of pea (Pisum sativum L.).
Selected flavonoids that are known as inducers and a suppressor of nodulation (nod) genes of the symbiotic bacterium Rhizobium leguminosarum bv. viciae were tested for their effect on symbiosisExpand

Rhizobial nod gene-inducing activity in pea nodulation mutants: dissociation of nodulation and flavonoid response.
The root exudates of 24 pea (Pisum sativum L.) non-nodulating mutants, originating from cv. 'Finale', were tested for Rhizobium nodulation (nod) gene-inducing activity to reveal potential differencesExpand

Absence of sex chromatin corresponds with a sex-chromosome univalent in females of Trichoptera
Five Trichoptera species, representing four different families of three suborders, have been examined for sex chromatin status in relation to their sex chromosome system. These were Hydropsyche sp.,Expand

A mutation affecting symbiosis in the pea line Risnod27 changes the ion selectivity filter of the DMI1 homolog
After identifying regions of cDNA conserved between the symbiotic gene DMI1 of the model species Medicago truncatula and the homologous genomic region of Arabidopsis thaliana, universal primers wereExpand

Optimization of rhizobialnod gene-inducing activity assay in pea root exudate
ThelacZ transcriptional fusion assay of the activation of rhizobialnod genes has been adapted for the microtitration plates. The assay can be performed reproducibly on a microscale, includingExpand
