The genetics of meiotic chromosome pairing in Lolium temulentum x Lolium perenne tetraploids
Theoretical and Applied Genetics, 1985The degree of preferential pairing of homologous chromosomes was estimated in a series of tetraploid hybrids of Lolium temulentum x Lolium perenne by means of cytological and genetic analyses. The correlations between the frequency of bivalents at first metaphase of meiosis in the hybrid tetraploids and the degree of preferential pairing calculated ...

Theoretical and Applied Genetics, 1982
Populations of induced polyploids invariably contain a substantial proportion of aneuploid individuals. A model is described which can predict the level of aneuploidy in successive generations of a closed population of Lolium tetraploids. The results demonstrate clearly that the proportion of aneuploid individuals increases sharply for two to three ...

Isolation, Culture and Regeneration of Lolium Perenne and Lolium Multiflorum Protoplasts
1988For the application of most genetic manipulation techniques a reliable system for plant regeneration from single cells and protoplasts is a prerequisite. In the Gramineae plant regeneration from protoplasts has been achieved only when morphogenically competent cell suspensions were used for protoplast isolation.

APPs (aryloxyphenoxypropionates) and CHDs (cyclohexanediones) are two of the most important groups used post-emergence for the control of grass weeds. They inhibit the lipid synthesis in plants by interfering with the activity of the enzyme Acetyl-coenzyme A carboxylase (ACCase), acting at a meristematic level.

Genetic Transformation of Protoplasts Isolated from Leaves of Lolium temulentum and Lolium perenne
2019Transient expression of inserted recombinant DNA in plant protoplasts is a widely used tool for functional genomics research. Recently it has been utilized to screen potential sgRNA guides for CRISPR-mediated genome editing. However, little research has been conducted into the use of transient expression of protoplasts in Lolium perenne (a globally ...

Stickstoffausnutzungsvermögen von Lolium perenne und Lolium multiflorum‐Sorten
Journal of Agronomy and Crop Science, 1988Abstract Selection for improved nitrogen‐utilization in Lolium In a 3‐year study the responses of 14 Lolium perenne‐varieties and 14 of Lolium multiflorum to different nitrogen fertilization (75, 150, 300 kg N/ha) were investigated. The varieties were classificated into four types of nitrogen utilization. “Low input varieties” can be found in type III.

Chromosoma, 1976
Cytomixis is a spontaneous process occurring through the formation of cytoplasmic bridges between adjacent pollen mother cells. This phenomenon was observed in the pollen mother cells of 3 genotypes of Lolium perenne which had been subjected to directional selection for productivity of green material.
