Isolation and characterization of cold-regulated transcriptional activator LpCBF3 gene from perennial ryegrass (Lolium perenne L.).

In plants, low temperatures can activate the CBF cold response pathway playing a prominent role in cold acclimation by triggering a set of cold-related gene expressions. CBF homologous gene, designated as LpCBF3, from a cold-tolerant perennial ryegrass (Lolium perenne L.) accession was identified.

Analysis of EST sequences suggests recent origin of allotetraploid colonial and creeping bentgrasses.

Advances in plant genomics have permitted the analysis of several members of the grass family, including the major domesticated species, and provided new insights into the evolution of the major crops on earth. Two members, colonial bentgrass (Agrostis capillaris L.) and creeping bentgrass (A.

Monitoring of gene expression profiles and identification of candidate genes involved in drought responses in Festuca mairei.

To understand the molecular genetic basis underlying drought tolerance in grasses, the cDNA-amplified fragment length polymorphism (cDNA-AFLP) technique was applied for identification of genes responding to drought stress in a xerophytic adapted plant, Festuca mairei. A total of 11,346 transcript derived fragments (TDFs) were detected, and 464 (4.1%) TDFs were identified as differentially expressed fragments (DEFs) during the drought treatment of the plant.

Genetic diversity in colonial bentgrass (Agrostis capillaris L.) revealed by EcoRI-MseI and PstI-MseI AFLP markers.

Colonial bentgrass (Agrostis capillaris L.) is a potential source for genetic improvement of resistance to environmental stress and disease for other bentgrass species (Agrostis spp.).

Detection of an efficient restriction enzyme combination for cDNA-AFLP analysis in Festuca mairei and evaluation of the identity of transcript-derived fragments.

In cDNA-amplified fragment length polymorphism (cDNA-AFLP) analysis, it is critical to choose a suitable pair of restriction enzymes for tagging sites in cDNA for amplification. Possibility of production of chimeric fragments from cDNA-AFLP analysis remains to be researched. The objectives of this study were to detect an efficient restriction enzyme combination for cDNA-AFLP analysis when Festuca species was used as template, and to evaluate the identity of transcript-derived fragments (TDFs) from cDNA-AFLP analysis.

Genetic variability of grey snow mould (Typhula incarnata).

Randomly amplified polymorphic DNA (RAPD) markers were used to assess the genetic diversity of isolates of grey snow mould ('gray snow mold'), Typhula incarnata, taken from infected turfgrasses from 40 different locations in the northern USA. Data from 115 markers using 37 RAPD primers showed 48 % polymorphism. The distance coefficients between isolates indicate the wide genetic diversity of T.

Comparison of tall fescue (Cyperales: Gramineae) to other cool-season turfgrasses for tolerance to European chafer (Coleoptera: Scarabaeidae).

Three cultivars of tall fescue, Festuca arundinacea Schreb., were compared with three cultivars each of fine fescue (Festuca spp.), Kentucky bluegrass (Poa pratensis L.
