Rice pseudomolecule-anchored cross-species DNA sequence alignments indicate regional genomic variation in expressed sequence conservation (2007)
Journal Article

Background Various methods have been developed to explore inter-genomic relationships among plant species. Here, we present a sequence similarity analysis based upon comparison of transcript-assembly and methylation-filtered databases from five plan...

From phenotype to genotype: whole tissue profiling for plant breeding (2007)
Journal Article

Fourier transform infrared spectroscopy (FT-IR) was used to obtain ‘holistic’ metabolic fingerprints from a wide range of plants to differentiate species, population, single plant genotype, and chromosomal constitution differences. Sample preparation... Read More about From phenotype to genotype: whole tissue profiling for plant breeding.

Introgression mapping in the grasses (2007)
Journal Article

The unique properties of Lolium/Festuca hybrids and their derivatives provide an ideal system for intergeneric introgression. At IGER a focus on the Lolium perenne/Festuca pratensis system is being exploited to elucidate genome organization in the gr... Read More about Introgression mapping in the grasses.

Cross-Species Identification of Mendel's I Locus (2007)
Journal Article

A key gene involved in plant senescence, mutations of which partially disable chlorophyll catabolism and confer stay-green leaf and cotyledon phenotypes, has been identified in Pisum sativum, Arabidopsis thaliana, and Festuca pratensis by using class...

Quantitative Fusarium spp. and Microdochium spp. PCR assays to evaluate seed treatments for the control of Fusarium seedling blight of wheat (2006)
Journal Article

Aims: To develop sensitive quantitative PCR assays for the two groups of pathogens responsible for Fusarium seedling blight in wheat: Fusarium group (Fusarium culmorum and Fusarium graminearum) and Microdochium group (Microdochium nivale and Microdoc...

Developing digital records: Early experiences of record and replay (2006)
Journal Article

In this paper we consider the development of 'digital records' to support ethnographic study of interaction and collaboration in ubiquitous computing environments and articulate the core concept of 'record and replay' through two case studies. One fo... Read More about Developing digital records: Early experiences of record and replay.

Effect of eyespot caused by Oculimacula yallundae and O. acuformis, assessed visually and by competitive PCR, on stem strength associated with lodging resistance and yield of winter wheat (2006)
Journal Article

Winter wheat, (cv. Consort) was inoculated with three isolates of either Oculimacula yallundae or O. acuformis to determine the effect of eyespot caused by each species on yield and lodging resistance of winter wheat. Plants were visually assessed fo...

Alignment of the Genomes of Brachypodium distachyon and Temperate Cereals and Grasses Using Bacterial Artificial Chromosome Landing With Fluorescence in Situ Hybridization (2006)
Journal Article

As part of an initiative to develop Brachypodium distachyon as a genomic “bridge” species between rice and the temperate cereals and grasses, a BAC library has been constructed for the two diploid (2n = 2x = 10) genotypes, ABR1 and ABR5. The library...

Molecular tagging of a senescence gene by introgression mapping of a stay-green mutation from Festuca pratensis (2004)
Journal Article

Intergeneric hybrids between Lolium multiflorum and Festuca pratensis (Lm/Fp) and their derivatives exhibit a unique combination of genetic and cytogenetic characteristics: chromosomes undergo a high frequency of homoeologous recombination at meiosis...

Stromule formation is dependent upon plastid size, plastid differentiation status and the density of plastids within the cell (2004)
Journal Article

Stromules are motile extensions of the plastid envelope membrane, whose roles are not fully understood. They are present on all plastid types but are more common and extensive on non-green plastids that are sparsely distributed within the cell. Durin...

Effects of fungicides on eyespot, caused predominantly by Oculimacula acuformis, and yield of early-drilled winter wheat (2004)
Journal Article

The effectiveness against eyespot of nine fungicide treatments, applied at GS 31, was evaluated in early-drilled winter wheat crops. Visual assessments of stem-base diseases were made before fungicide application and at GS 39/55 and 69/70 of cultivar...

Synteny between a major heading-date QTL in perennial ryegrass (Lolium perenne L.) and the Hd3 heading-date locus in rice (2003)
Journal Article

The genetic control of induction to flowering has been studied extensively in both model and crop species because of its fundamental biological and economic significance. An ultimate aim of many of these studies has been the application of the unders...

Comparison and integration of genetic maps generated from F2 and BC1-type mapping populations in perennial ryegrass (2002)
Journal Article

Linkage maps of perennial ryegrass were constructed from F2 and BC1?type populations using, predominantly, restriction fragment length polymorphism data based on heterologous probes used in mapping other grass species.
