| Outline of Final Research Achievements |
Lichen is a symbiotic organism composed of fungus and alga (and/or cyanobacterium). The morphological, ecological and physiological natures of lichens are fundamentally designed by the results of symbiosis. Gene-expressions related to the symbiosis of lichens, however, have been poorly understood. This study intended to explore which genes are involved to lichen symbiosis using a next generation sequencer, and to study gene expressions in morphological transformations of lichen photobiont. As the results, we found the differences of gene expressions related to protein or nitrogen-compound synthesis pathway between dry and wet conditions of natural thalli. The photobiont of Botryolepraria lesdainii was newly identified as Sticococcus mirabilis. Morphology of this alga is proved to be spherical with symbiotic condition in the field and elongated with non-symbiotic condition in a culture. The mRNA were extracted from both conditions and will be analyzed in the further researches.
