Similarity of Ribulose-1,5-bisphosphate Carboxylases of Isogenic Diploid and Tetraploid Ryegrass (Lolium perenne L.) Cultivars.
Partially purified ribulose-1,5-bisphosphate carboxylase (EC 4.1.1.39) was isolated from diploid and tetraploid cultivars of ryegrass (Lolium perenne L.) using two separate methods. The apparent K(m) (CO(2)) values for the enzymes prepared by either method did not differ significantly between diploid and tetraploid when assayed by two separate techniques. The unpurified enzymes from freshly lys...
متن کاملVernalization Mediated Changes in the Lolium perenne Transcriptome
Vernalization is a key requirement for the induction of flowering in perennial ryegrass (Lolium perenne L.). The transcriptome of two genotypes with contrasting vernalization requirement was studied during primary (vernalization and short day conditions) and secondary induction (higher temperature and long day conditions) using an RNA-Seq approach. This revealed transcripts with expression prof...
متن کاملACREMONIUM-ENDOPHYTES OF PERENNIAL RYEGRASS (Lolium perenne) IN FRANCE
13-17 ABSTRACT Infection with endophytic fungi (Acremonium spp.) was detected in seeds of wild populations of perennial ryegrass (Lolium perenne) collected in France by private breeding companies and INRA. In total, 262 populations were examined and 70% contained Acremonium. It is worth noticing that most populations are endophyte infected but generally endophyte infection rates per population ...
متن کاملImplementation of Genomic Prediction in Lolium perenne (L.) Breeding Populations
Perennial ryegrass (Lolium perenne L.) is one of the most widely grown forage grasses in temperate agriculture. In order to maintain and increase its usage as forage in livestock agriculture, there is a continued need for improvement in biomass yield, quality, disease resistance, and seed yield. Genetic gain for traits such as biomass yield has been relatively modest. This has been attributed t...
متن کاملTranscriptional and metabolic profiles of Lolium perenne L. genotypes in response to a PEG-induced water stress.
Metabolic profiling was carried out in the forage grass Lolium perenne L. (perennial ryegrass) to uncover mechanisms involved in the plants response to water stress. When leaf and root materials from two genotypes, with a contrasting water stress response, were analysed by GC-MS, a clear difference in the metabolic profiles of the leaf tissue under water stress was observed. Differences were pr...
