  1. Student's t-test was applied to loadings of the ORFs and only those ORFs with t < 1 × 10-5 (within confidence interval 99.999%) are listed in the Table. GO Mapping was applied to these ORFs and only the top five significant biological process terms are given. (+) and (-) signs indicate positive and negative loadings of the ORFs, respectively.
