Grass-endophyte interactions: a note on the role of monosaccharide transport in the Neotyphodium lolii-Lolium perenne symbiosis.
Symbiotic mutualistic associations of plants with ectoand endomycorrhizal and endophytic fungi are very common in natural and agricultural ecosystems; these fungi improve nutrient acquisition and ⁄ or tolerance to biotic and abiotic stresses of their hosts (Smith & Gianinazzi-Pearson, 1988; Nehls et al., 2007; Schardl et al., 2007). A major feature of associations between the heterotrophic fung...
متن کاملDetection of lpsA Gene in Neotyphodium endophytic Fungi of Grasses in Iran
The lpsA gene, a late acting gene in the biosynthetic pathway of ergovaline, a suspected causative agent for fescue toxicosis in cattle, has been cloned from Neotyphodium lolii, an endophytic fungus of Lolium perenne. In this study, a similar gene was detected in several strains of endophytic Neotyphodium spp. isolated from grass hosts endogenous to Iran using direct and nested-PCR assays. Exce...
متن کاملCharacterization of the vernalization response in Lolium perenne by a cDNA microarray approach.
Many plant species including temperate grasses require vernalization in order to flower. Vernalization is the process of promotion of flowering after exposure to prolonged periods of cold. To investigate the vernalization response in monocots, the expression patterns of about 1,500 unique genes of Lolium perenne were analyzed by a cDNA microarray approach, at different time points after transfe...
متن کاملA multidisciplinary approach to dissect the molecular basis of the Neotyphodium lolii/ryegrass symbiosis
Neotyphodium lolii is a fungal endophyte that lives entirely within the intercellular spaces of its grass host, perennial ryegrass (Lolium perenne L.). Infection is symptomless and the endophyte relies on the host plant for dissemination via the seed. The association is mutually beneficial since the endophyte confers a number of biotic and abiotic advantages to the host. This paper will present...
متن کاملcAMP Signaling Regulates Synchronised Growth of Symbiotic Epichloë Fungi with the Host Grass Lolium perenne
The seed-transmitted fungal symbiont, Epichloë festucae, colonizes grasses by infecting host tissues as they form on the shoot apical meristem (SAM) of the seedling. How this fungus accommodates the complexities of plant development to successfully colonize the leaves and inflorescences is unclear. Since adenosine 3', 5'-cyclic monophosphate (cAMP)-dependent signaling is often essential for hos...
