Mycorrhiza and Host Specificity.

In my previous papers and discussions, I have explained how Rhizobium and Mycorrhiza could be a possible danger to the ecosystems that they inhibit. In this poster I am going to highlight some research which would explain how host specificity and initial difficulty of culturing Mycorrhiza in vitro and vivo was an indication of its unsuitability on agriculture land.

There has been a significant emphasis on positive growth studies utilizing Mycorrhiza, but the studies that depicted a negative growth curve with the introduction of Mycorrhiza were deemed unsuccessful, as a result, in some cases were not provided a degree of completion or an extension to further study Mycorrhiza. Whereas these studies are equally important for understanding Mycorrhiza as were the positive growth and germination studies.
Some of these thankfully have made to some of the journals, due to which it is possible to write this paper. The negative studies of reduction in growth of seedling size and decrease in percentage germination of seeds is a result of an infective stage of Mycorrhiza which does not allow the development of the seeds and seedling growth. Little emphasis is paid on the choice of seeds for carrying out experimentation. There are no studies carried out using diseased or deteriorated seeds, therefore there is a possibility that the seeds that show an enhanced germination in the presence of Mycorrhiza are stronger than the ones unable to cope under its infectious stage. 

There are Mycorrhiza studies undertaken under environmental stress conditions rarely with diseased or weak seeds, in order to find out if a genetically weakened seed can be made to grow, utilizing Mycorrhiza. Until that happens it is very difficult to consider Mycorrhiza for use beyond the forest land. Utilizing Mycorrhiza for gardens can also be considered problematic since its presence in certain fragranced flower types can become a cause of their entry in the food chain.

In this poster I am going to highlight some of the negative growth studies associated with Mycorrhiza and reanalyze some of the reasons that might be associated with the negative response and how that might impact our understanding of the symbiotic relationship. It will also try and provide some possible reasons for sensitivity of Mycorrhiza to be cloned under lab (aseptic) conditions.
