The thioredoxin gene family in rice: Genome-wide identification and expression profiling under different biotic and abiotic treatments

► Genome-wide survey among six species. ► Compared potential gene birth-and-death events in the OsTRX. ► Gene duplication, evolution and synteny analysis. ► Gene expression profiles of biotic and abiotic stresses were observed in rice. ► Selected the candidate genes for functional analysis.
