Photosynthesis and Photorespiration inLolium multiflorumandLolium perenne
Journal of Experimental Botany, 1971The response of net photosynthesis to changing light-flux density by leaves of Lolium multiflorum (S. 22) and L. perenne (S. 321) is more adequately described by current models when a term allowing for photorespiration is included. The magnitude of this term was determined from the changes in the slope of the light-response curves for net ...

Chromosoma, 1978
Eighteen plants displaying varying degrees of asynapsis ranging from weak to very strong were found among four out of six populations of Lolium perenne L. (2n=14) which had been subjected to three cycles of directional phenotypic selection for productivity of green material.

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 ...

Australian Journal of Botany, 1983
The genus Lolium is represented in Australia by the following five species: L. perenne, L. multiflorum, L. rigidum, L. loliaceum and L. temulentum. L. remotum is probably extinct in Australia as it has been found only associated with flax crops which are no longer grown locally.

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 ...

Synaptonemal complex formation in hybrids of Lolium temulentum � Lolium perenne (L.)
Chromosoma, 1985The chromosomes of Lolium temulentum are longer and contain on average 50% more nuclear DNA than the chromosomes of L. perenne. In the hybrid, despite the difference in length and DNA content, pairing between the homoeologous chromosomes at pachytene is effective and the chiasma frequency at first metaphase in pollen mother cells is high, about 1.6 per
