The amino acid sequences of human and yeast DExD/H-box RHs were BLAST-searched against the protein databases of Arabidopsis, rice, and maize available at Ensembl Plants (http://plants.ensembl.org). The protein sequences showing the highest similarity were considered as homologs. Data for abiotic stress-responsiveness were obtained from eFP Brower (http://bar.utoronto.ca/efp_arabidopsis/) for Arabidopsis and GENEVESTIGATOR (https://genevestigator.com) for rice and maize. The genes showing a fold change >2 are indicated as C, cold inducible; D, drought inducible; S, salt inducible; and H, heat inducible following the annotation numbers. Asterisk “∗” indicates the Arabidopsis nucleolar DEAD-box RHs reported as human and yeast RBFs orthologs (Palm et al., 2016).
