Substitution of a species or cultivar with higher uptake of an element by one with lower uptake has been proposed as a remediation strategy following accidental releases of radioactivity. However, despite the importance of pasture systems for radiological dose, species/cultivar substitution has not been thoroughly investigated for forage grasses. 397 cultivars from four forage grass species; hy...

Within the Oltenia surface mining region of Romania, 14,890 ha have been disturbed and only 1,002 ha have been reclaimed. The majority of this disturbance has involved agricultural land (12,208 ha), of which only a small amount has been reclaimed (552 ha). Forest land disturbed by surface mining in this region amounted to 2,682 ha, of which only 450 ha have been reclaimed. Therefore, huge land ...

Heat shock factors (Hsfs) are important regulators of stress-response in plants. However, our understanding of Hsf genes and their responses to temperature stresses in two Pooideae cool-season grasses, Festuca arundinacea, and Lolium perenne, is limited. Here we conducted comparative transcriptome analyses of plant leaves exposed to heat or cold stress for 10 h. Approximately, 30% and 25% of th...

The main storage compounds in Lolium perenne are fructans with prevailing β(2-6) linkages. A cDNA library of L. perenne was screened using Poa secunda sucrose:fructan 6-fructosyltransferase (6-SFT) as a probe. A full-length Lp6-SFT clone was isolated as shown by heterologous expression in Pichia pastoris. High levels of Lp6-SFT transcription were found in the growth zone of elongating leaves an...

Pastures are important for the agricultural sector as forage, recreational and sports systems. The Chilean pasture seed market is highly dependent on introduced genetics; however, effect of climate change conditions can modify options. objective this study was to quantify changes seeds sown by end-users, metric tons (Mt) or proportion total (PT), based 19 years imported seed. Mann–Kendall test ...
