Molecular Approaches In The Analysis Of Red Clover Rhizobium Symbiosis, Randy D. Dinkins, L. Koch, M. L. Sullivan, H. Zhu
Molecular Approaches In The Analysis Of Red Clover Rhizobium Symbiosis, Randy D. Dinkins, L. Koch, M. L. Sullivan, H. Zhu
IGC Proceedings (1997-2023)
Red clover (Trifolium pratense L.) is an important forage and pasture legume grown throughout temperate regions. Because it can form a symbiotic relationship with rhizobium, it is able to fix atmospheric nitrogen. Due to the high cost of nitrogen fertilizers, pasture legumes have been increasingly important in forage production settings. Red clover has not been a model legume primarily due to selfincompatibility and the associated high level of genomic heterozygosity, therefore it has not been a significant contributor in molecular or genetic studies and basic information on red clover legume/rhizobium symbiosis is lacking. Using recently annotated genomic resources, RNA-seq …
Light Intensity Is Positively Correlated With The Synthesis Of Condensed Tannins In Lotus Corniculatus, Sergio Arcioni, T. Bovone, F. Damiani, F. Paolocci
Light Intensity Is Positively Correlated With The Synthesis Of Condensed Tannins In Lotus Corniculatus, Sergio Arcioni, T. Bovone, F. Damiani, F. Paolocci
IGC Proceedings (1997-2023)
The importance of Condensed Tannins (CT) in forage legumes has been well documented in several studies. The role of plant genetics in this field is the acquisition of competences in order to be able to modulate CT synthesis in leaves of these species. The role of light has been investigated in this work on the increase of condensed tannin levels in leaves of two contrasting genotypes of birdsfoot trefoil (Lotus corniculatus).
The Investigation Of Flowering Control In Late/Rare Flowering Lolium Perenne, S. Byrne, I. S. Donnison, L. J. Mur, E. Guiney
The Investigation Of Flowering Control In Late/Rare Flowering Lolium Perenne, S. Byrne, I. S. Donnison, L. J. Mur, E. Guiney
IGC Proceedings (1997-2023)
Flowering in Lolium perenne (perennial ryegrass) results in reduced digestibility and its inhibition would enhance forage quality. Flowering regulation has been well studied in Arabidopsis thaliana (Simpson and Dean, 2002) and orthologs of Arabidopsis flowering genes underlying heading date Quantitative Trait Loci (QTL) have been identified in rice (Yano, M et al., 2000). However it is not clear yet how universally applicable such studies are to Lolium. The project goals are to characterise the gene expression profiles of late/rare flowering L. perenne plants to determine factors affecting flowering and to map the genes involved in the flowering process. Initial …
Biological Interactions In Grassland Soils And Productivity, R. Cook, R. D. Bardgett, W. R. Eason, L. Skøt, K. J. Webb
Biological Interactions In Grassland Soils And Productivity, R. Cook, R. D. Bardgett, W. R. Eason, L. Skøt, K. J. Webb
IGC Proceedings (1997-2023)
This paper describes research on interactions between grassland plant species and soil microorganisms. Both parasitic and symbiotic microorganisms modify nutrient transfers between plants and soil. Experiments are described in which nematode infection of clover increased nitrogen transfer to companion ryegrass plants. Infection of clover enhanced activity of soil bacterial and fungal communities. Legume genotypes differing only in responses to symbionts (rhizobium and arbuscular mycorrhizal fungi) and pathogens are being developed for studies of gene expression during establishing and functional symbioses. Such plants can be used in experiments as defined perturbations that will provide information on the interactions and functions of …

Increases in fruit weight of cultivated vegetables and fruits accompanied the domestication of these crops. Here we report on the positional cloning of a quantitative trait locus (QTL) controlling fruit weight in tomato. The derived allele of Cell Size Regulator (CSR-D) increases fruit weight predominantly through enlargement of the pericarp areas. The expanded pericarp tissues result from increased mesocarp cell size and not from increased number of cell layers. The effect of CSR on fruit weight and cell size is found across different genetic backgrounds implying a consistent impact of the locus on the trait. In fruits, CSR …

Rapeseed (Brassica napus) is an important oil seed crop, providing more than 13% of the world’s supply of edible oils. An in-depth knowledge of the gene network involved in biosynthesis and accumulation of seed oil is critical for the improvement of B. napus. Using available genomic and transcriptomic resources, we identified 1,750 acyl-lipid metabolism (ALM) genes that are distributed over 19 chromosomes in the B. napus genome. B. rapa and B. oleracea, two diploid progenitors of B. napus, contributed almost equally to the ALM genes. Genome collinearity analysis demonstrated that the majority of the …
