Being a farm girl, my fall months were spent helping my mom and grandma can fruit and vegetables from our gardens to eat during the winter months. For decades, glass canning jars had just one use, and that was to store food for the future.

Received Sep 4; Accepted Oct This article has been cited by other articles in PMC. Here we briefly review the most recent findings in these areas of research using the present knowledge of the genetic variation that explains the biosynthetic pathways driving the diversity of alkaloids produced by the endophyte.

These findings underscore the importance of genetic interplay between the fungus and the host in shaping their coevolution and ecological role in both natural grass ecosystems, and in the agricultural arena. Fungal endophytes, Grass, Genetic variation, Alkaloids, Coevolution Introduction Specialization and coevolution have taken the center stage of discussion in evolutionary biology since Darwin emphasized in Origin of Species how species diversity and interactions together shape the evolution of life from individuals to communities Darwin ; Thompson Thus, the majority of evolution fundamentally incorporates the elements of coevolutionary processes, and specialization commonly plays a role, especially in tightly linked species interactions such as symbiotic microbial interactions.

By definition, fungal endophytes live internally and asymptomatically within organs of their host plant Wilson These asymptomatic fungal infections are ubiquitous, abundant and taxonomically diverse residents in all terrestrial plants Saikkonen et al.

First, the fungal hypha grows throughout the above-ground tissues of the host grass including inflorescences. It remains restricted to the intercellular spaces.

Such an intimate relationship requires adaptations allowing the fungus to access the host plant interior, perhaps suppressing the recognition and defense responses that normally halt the establishment of harmful fungal infections in the host plant Hamilton et al. The associated mechanisms are poorly understood but the oxidative balance is suggested to play a role Hamilton et al.

Second, the fitness of the partners is tightly linked, which should favor the evolution of interaction toward reduced antagonism and increased partner fidelity Thompson ; Saikkonen et al.

In exchange for hosting the endophyte, the host grass can receive benefits such as competitive superiority compared to uninfected counterparts in a population through increased growth and reproduction, as well as resistance to various abiotic and biotic stresses such as drought, flooding, pathogens and herbivores Clay; Saikkonen et al.

Thus, the symbiosis can range from antagonistic to mutualistic, and conflicting selection forces are likely to destabilize them.

The benefits from endophytes appear to be dependent on the fungal and host genotype, and on environmental conditions. Accordingly, the symbioses are commonly regarded either as commensal or mutualistic. The major destabilizing forces in the symbiosis are asymmetry in dependence and genetic compatibility.

Red fruit colour ‘R’ is dominant over yellow ‘r’. Answer: Red fruit – RR or Rr Yellow fruit –rr Red is completely dominant over yellow. In the given data above the offspring segregate in an approximate ratio of If the wild type dihybrid flies are crossed to produce progeny, how many of these progeny are expected in each.

Sep 10,  · He has compiled of the best bets in his new book, Bets You Will Always Win. Today, he joins Math Dude Jason Marshall for a short interview to discuss how probability and mathematics can play a role in winning bets.

However, here we focus on functional genetics driving alkaloid production because defense against herbivores is suggested to be the primary driving selective force behind the mutualism Clay ; Saikkonen et al. The stroma produces spermatia and trichogynes female receptive hyphae and attracts female Botanophila sp.

Since there is no genetic difference in the fungus associated with choked versus asymptomatic tillers on an individual plant, it seems likely that this duality of reproductive processes has an epigenetic basis.

Some of these can still form sparse hyphal nets that produce some conidia White et al. Such polyploid, asexual hybrids seem unusual among fungi, though well documented in the Verticillium dahliae species complex Inderbitzin et al. Strikingly, the deepest split identified is to a clade of two species symbiotic with Achnatherum species Fig.
