Comparative functional genomics can provide powerful approaches to draw inferences about gene lt br gt function and evolution among species. The comprehensive comparison of bHLH gene family in different lt br gt gramineous plants has not yet been reported. lt br gt Results In this study a total of 183 231 and 571 bHLHs were identified in rice maize and wheat genomes respectively and lt br gt 1154 bHLH genes from the three species and Arabidopsis were classified into 36 subfamilies. Of the identified genes 110 lt br gt OsbHLHs 188 ZmbHLHs and 209 TabHLHs with relatively high mRNA abundances were detected in one or more tissues lt br gt during development and some of them exhibited tissue-specific expression such as TabHLH454 459 ZmbHLH099 101 and lt br gt OsbHLH037 in root TabHLH559 562 046 047 and ZmbHLH010 072 226 in leaf TabHLH216 221 333 335 340 lt br gt and OsbHLH005 141 in inflorescence TabHLH081 ZmbHLH139 and OsbHLH144 in seed. Forty five twenty nine and thirty lt br gt one differentially expressed bHLHs were respectively detected in wheat maize and rice under drought stresses using RNA- lt br gt seq technology. Among them the expressions of TabHLH046 047 ZmbHLH097
