Table 1 Known unigenes showing significant expression differences between symbiotic and aposymbiotic anemones. Identification was based on significant blast hits (E values < 10-4) from GenBank. Ratios of expression from all microarray analyses and selected Q-RT-PCR analyses are shown. Arrows indicate the direction of expression as a function of symbiosis: up- or down-regulation. Those genes highlighted in bold are discussed in the text. Significance is indicated as follows: P < 0.05 (*), P < 0.01 (**).
