A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line 2n = 2x = 14. In this line recombination occurs throughout the length of the F. pratensis/L. perenne bivalent. The F. pratensis chromosome and recombinants between it and its L. perenne homeologue can be visualized using genomic in situ hybridizat...

Few studies to date have considered the responses of agriculturally important forage grasses to UV-B radiation. Yet grasses such as Lolium perenne have a wide current distribution, representing exposure to a significant variation in ambient UV-B. The current study investigated the responses of L. perenne (cv. AberDart) to a simulated latitudinal gradient of UV-B exposure, representing biologica...

The repeated evolution of herbicide resistance in weeds is an ongoing problem in agricultural regions across the world, and presents a unique system in which to study the origins and spread of adaptive traits across heterogeneous landscapes. Lolium perenne ssp. multiflorum (Lam.) (Italian ryegrass) is a widespread grass weed of agricultural crops that has repeatedly evolved resistance to herbic...

Lolium perenne, which is a major component of pastures, lawns, and grass strips, can be exposed to xenobiotic stresses due to diffuse and residual contaminations of soil. L. perenne was recently shown to undergo metabolic adjustments in response to sub-toxic levels of xenobiotics. To gain insight in such chemical stress responses, a de novo transcriptome analysis was carried out on leaves from ...

This study was conducted in laboratory conditions to determine the response of some cool season turf grass species (Lolium perenne Caddieshack, Lolium multiflorum Jivet, Poa pratensis Evora, Festuca rubra Rassinante, arundinacea Starlet, ovina Ridu) different salt doses during germination period. In study, 8 NaCl doses, 0, 30, 60, 90, 120, 150, 180, 210 mM, were applied, rate (%), time plumula ...

Stress management is considered as an important factor in nowadays landscape. Therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (Lolium...

Application of strategies induced a heavy metal tolerant turfgrass is necessary for cultivation management. Water and soil contamination with heavy metals is an increasing concern for the human and environment health. This study was conducted to evaluate the mitigation of environmental Cd toxicity through landscape turfgrasses as affected by two arbuscular mycorrhizal fungi (AMF) species and to...

Reestablishment of damaged golf greens and fairways planted to creeping bentgrass ( Agrostis stolonifera ), colonial A. capillaris velvet canina ) is a common practice following winter injuries. Identifying species sp.) cultivars with the potential establish under low soil temperatures would be beneficial achieving more mature stands earlier in spring. Twelve cultivars, including seven (007, 13...

Herbicide resistance in wild grasses is widespread in the UK, with non-target site resistance (NTSR) to multiple chemistries being particularly problematic in weed control. As a complex trait, NTSR is driven by complex evolutionary pressures and the growing awareness of the role of the phytobiome in plant abiotic stress tolerance, led us to sequence the transcriptomes of herbicide resistant and...
