Neotyphodium endophytic fungi, the asexual state of Epichloë species, protect cool-season grasses against stresses. The outcomes of Neotyphodium-grass symbioses are agronomically relevant as they may affect the productivity of pastures. It has been suggested that the mutualism is characteristic of agronomic grasses and that differential rates of gene flow between both partners’ populations are expected to disrupt the specificity of the association and, thus, the mutualism in wild grasses. We propose that compatibility is necessary but not sufficient to explain the outcomes of Neotyphodium-grass symbiosis, and advance a model that links genetic compatibility, mutualism effectiveness, and endophyte transmission efficiency. For endophytes that reproduce clonally and depend on allogamous hosts for reproduction and dissemination, we propose that this symbiosis works as an integrated entity where gene flow promotes its fitness and evolution. Compatibility between the host plant and the fungal endophyte would be high in genetically close parents; however, mutualism effectiveness and transmission efficiency would be low in fitness depressed host plants. Increasing the genetic distance of mating parents would increase mutualism effectiveness and transmission efficiency. This tendency would be broken when the genetic distance between parents is high (out-breeding depression). Our model allows for testable hypotheses that would contribute to understand the coevolutionary origin and future of the endophyte-grass mutualism.

“…This approach is highly reproducible and has relatively low cost (Bornet and Branchard, 2001). ISSR analysis has been used to assess the genetic diversity of a large number of plant species, including Lolium spp (Dinelli et al, 2004) and Cynodon dactylon (Wang et al, 2013). Both SSRs and ISSRs are powerful and useful tools for genetic studies and have been used in several plant species; however, at present, reports remain P. Madesis et al limited about their use in studies of D. glomerata populations (Litrico et al, 2009;Xie et al, 2010Xie et al, , 2012.…”

ABSTRACT. Dactylis glomerata L. is an important forage species in the Mediterranean region, and in other regions with a similar climate. Genetic material from 3 locations in north, central, and south Greece was studied, using morphological traits, SSR, and ISSR molecular markers. Morphological analysis revealed differences among the geographic locations studied for all morphological traits, except the number of reproductive tillers. Moreover, the highest phenotypic variation was observed on the accessions from south, while the lowest was observed on the accessions from the north. Although the results of the molecular marker analysis are indicative, a high level of Morphological and genetic diversity of Dactylis glomerata genetic diversity at the species level was revealed by ISSRs (G ST = 0.291) and SSRs (F ST = 0.186). Analysis of molecular variance showed that a high level of genetic diversity existed for ISSRs and SSRs within populations (62 and 83%, respectively), rather than among populations (38 and 17%, respectively). Cluster analysis divided the 3 populations in 2 groups, with the population originating from the island of Crete forming 1 group, while the populations from north Greece (Taxiarchis) and central Greece (Pertouli) were clustered in a 2nd group. In general, the results indicate that SSRs are more informative compared to ISSRs about the genetic variation within a population, whereas the ISSRs were more informative about the genetic diversity among populations However, a similar trend in diversity (genotypic and phenotypic) was observed in the morphological traits and microsatellite-based (SSR/ISSR) markers at the locations studied.

“…Inter Simple Sequence Repeat (ISSR) PCR is a fast, cheap approach to genetic characterization and is widely used for ecological (Wu et al, 2004;Poulin, Weller and Sakai, 2005), population (Esselman et al, 1999;Alexander, Liston and Popovich, 2004;Song et al, 2006;Zhang et al, 2013) or phylogenetic studies (Joshi et al, 2000;Bussell, Waycott and Chappill, 2005), as well as in crop cultivar or native plant fingerprinting (Mattioni et al, 2002;Souza et al, 2005). It has been also applied to explore the hybrid origin of species (Ayres and Strong, 2001) and for systematic purposes (Blair, Panaud and McCouch, 1999;Vanderpoorten, Hedenäs and Jacquemart, 2003;Dinelli, 2004;Vergara et al, 2008). ISSRs have a few advantages over other molecular markers.…”

Chascolytrum Desv. is a South American grass genus, with extension up to Central America, which presents several taxonomic controversies concerning genera and species circumscriptions. Morphological studies were not able to provide robust elements for taxonomic decisions in some species complexes. It was the case of Chascolytrum subaristatum and morphological allies, and of Chascolytrum rufum plus the acceptance (or rejection) of two varieties. In order to provide additional elements for taxonomic decisions in these species complexes, it was performed a preliminary survey using Inter Simple Sequence Repeat (ISSR) markers. Nine primers were used to build similarity dendrograms, and 25 collections were included, analysed in two separated complexes. ISSR were able to separate the two varieties of Chascolytrum rufum, supporting their acceptance. Two species recently described could be clearly separated from their morphologically related taxa, but the species Briza erecta, Briza macrostachya and Chascolytrum subaristatum, as well as Briza subaristata var. interrupta, could not be separated, adding elements to the synonymization of these three taxa under Chascolytrum ubaristatum. The ISSR contributed to solving some controversies on genus Chascolytrum, but its use as an exclusive species-marker is limited in this genus due to high band polymorphism.
