Analysis of the arabidopsis REM gene family predicts functions during flower development

---

† Background and Aims The REM (Reproductive Meristem) gene family of Arabidopsis thaliana is part of the B3
DNA-binding domain superfamily. Despite the fact that several groups have worked on the REM genes for many
years, little is known about the function of this transcription factor family. This study aims to identify a set of REM genes involved in flower development and to characterize their function.

† Methods In order to provide an overviewof theREMgene family, a detailed expression analysis for allREMgenes
of A. thaliana was performed and combined with a meta-analysis of ChIP-sequencing and microarray experiments.

† Key Results Two sets of phylogenetically closely related REM genes, namely REM23, REM24 and REM25, and
REM34, REM35 and REM36, were identified as possibly being involved in the early stages of flower development.
Single- and double-mutant combinations were analysed for these genes, and no phenotypic effects were detected
during flower development.

†Conclusions The data suggest that the REM34, REM35 and REM36 group is the most interesting one, as REM34 is
co-expressed with the floral meristem identity (FMI) genes, they are bound by AP1, SVP, AP3 and PI, and they are expressed in the floral meristem and during the earliest stages of flower development. However, it appears that high levels of functional redundancy may conceal the exact function of these transcription factor genes.

Key words: Arabidopsis thaliana, transcription factor, reproductive meristem, REM gene, flower development,
B3 domain, floral meristem identity, FMI.
