Project description:Multi-omics analysis of the symbiotic green algae, Chlorella variabilis, revealing the genetic basis of the obligate endosymbiotic lifestyle
Project description:To assess the significant downstream pathways affected by the overexpression of LONELY GUY in Chlorella, transcriptome analysis was carried out using RNA sequencing of three biological replicates each from WT and LOG OX1 at 14 dpi (1h before dark phase). The 14 dpi was chosen for the analysis because it was in the middle of the growth phase, where the slower growth of LOG OX1 was evident.
Project description:Green hydra (Hydra viridissima) harbors endosymbiotic Chlorella and have established a mutual relation. To identify the host hydra genes involved in the specific symbiotic relationship, transcriptomes of intact H. viridissima colonized with symbiotic Chlorella strain A99, aposymbiotic H.viridissima and H. viridissima artificially infected with other symbiotic Chlorella were compared by microarray analysis. The results indicated that genes involved in nutrition supply to Chlorella were upregulated in the symbiotic hydra. In addition, it was induced by supply of photosynthates from the symbiont to the host, suggesting cooperative metabolic interaction between the host and the symbiotic algae.
