  1. A total of 56 (in shoot) and 39 (in root) A. donax DEGs for which rice orthologs could be identified are mapped onto the 15 co-expression modules previously identified in rice [70]. Significance levels for over- and under-representation as compared to rice (p-value) are provided
  2. There are 1392 rice genes in the 15 modules. Based on Blastp reciprocal best hits method, a total of 56 and 39 differentially expressed genes were identified as putative orthologs of rice genes in shoot and root of A. donax, respectively
