In summary, our experiment identified that OsRAF was an ethylene responsive gene. As mentioned in the introduction, no such genes in rice had been reported previously although ethylene responsive genes were extensively investigated in Arabidopsis and in tobacco. Moreover, our data from rice together with research from other species showed that these ERF genes were similar in function.In contrast, functions of AP2 subfamily members varied obviously. For example, APETALA2 and its homologues in maize and in petunia play different roles in plant development.An intriguing question is why stress responsive ERF members are more conserved in function, whereas development related AP2 members are more versatile? Further investigation will help us gain new insight into the function concerning this superfamily.<ref name="ref4" />

Gene Symbol

  • Os03g0183000 <=> OsERF#062

Function

  • Genes in the ERF family encode transcriptional regulators with a variety of functions involved in the developmental and physiological processes in plants.
  • It has been demonstrated that the AP2/ERF proteins have important functions in the transcriptional regulation of a variety of biological processes related to growth and development, as well as various responses to environmental stimuli.
  • Genes in the AP2 family have been shown to participate in the regulation of developmental processes, e.g. flower development (Elliott et al., 1996), spikelet meristem determinacy (Chuck et al., 1998), leaf epidermal cell identity (Moose and Sisco, 1996), and embryo development (Boutilier et al., 2002).[2]

Evolution

  • The ERF family is a large gene family of transcription factors and is part of the AP2/ERF superfamily, which also contains the AP2 and RAV families
  • The AP2/ERF superfamily is defined by the AP2/ERF domain, which consists of about 60 to 70 amino acids and is involved in DNA binding.
  • The AP2 family proteins contain two repeated AP2/ERF domains, the ERF family proteins contain a single AP2/ERF domain, and the RAV family proteins contain a B3 domain, which is a DNA-binding domain conserved in other plant-specific transcription factors, including VP1/ABI3, in addition to the single AP2/ERF domain.
  • The expansion of the ERF family in plants might have been due to chromosomal/segmental duplication and tandem duplication, as well as more ancient transposition and homing.
  • Since rice is a cultivated species, selection either during domestication from its wild ancestor or during agricultural improvement in the subsequent time may also have been important for the evolution of rice ERF family.[3]
