Afternoon Ascospore Release in Claviceps purpurea Optimizes Perennial Ryegrass Infection
Alderman, S. C., Walenta, D., Hamm, P. B., Martin, R. C., Dung, J., and Kosman, E. 2015. Afternoon ascospore release in Claviceps purpurea optimizes perennial ryegrass infection. Plant Dis. 99:1410-1415. In Kentucky bluegrass (Poa pratensis),Claviceps purpurea, the causal agent of ergot, typically releases ascospores during the early-morning hours, between about midnight and 10:00 A.M., corresp...
متن کاملUpdate on Perennial Roots and Lifespan Perennial Roots to Immortality
Maximum lifespan greatly varies among species, and it is not strictly determined; it can change with species evolution. Clonal growth is a major factor governing maximum lifespan. In the plant kingdom, the maximum lifespans described for clonal and nonclonal plants vary by an order of magnitude, with 43,600 and 5,062 years for Lomatia tasmanica and Pinus longaeva, respectively. Nonclonal perenn...
متن کاملSimulating perennial ryegrass cutting
Perennial ryegrass is one of the most commonly cultivated forage species in Europe, where grazing and mowing (cutting) are used to manage this resource. Cutting can be characterized by its intensity (height) and its frequency. Combinations of these two factors affect mono-species grasslands productivity and could also modify the genotypic composition of heterogeneous populations. Indeed, the hi...
متن کاملGlobal transcriptome changes in perennial ryegrass during early infection by pink snow mould
Lack of resistance to pink snow mould (Microdochium nivale) is a major constraint for adaptation of perennial ryegrass (Lolium perenne L.) to continental regions with long-lasting snow cover at higher latitudes. Almost all investigations of genetic variation in resistance have been performed using cold acclimated plants. However, there may be variation in resistance mechanisms that are function...
متن کاملPerennial allergic rhinitis and keratoconjunctivitis.
There are many studies dedicated to the allergic nose, but most of them deal with seasonal allergic rhinitis and particularly with acute experimental situations. Perennial allergic rhinitis is less well documented. When studying the allergic nose, several aspects must be taken into consideration: the genetic background of the patient, various environmental factors (antigens, air pollution, clim...
