🌱📖 RESEARCH 🌱📖 Bascom et al. used CRIPSR/Cas9 to produce a septuple AUXIN RESPONSE FACTOR mutant in the model bryophyte Physcomitrium patens , revealing the developmental consequences of the complete loss of auxin-mediated gene activation 🌱📖 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪
Fig. 4.Model of auxin de-repression. When the auxin concentration in the nucleus is low (A), the effect of ARFas, as well as other non-ARF transcription factors, is limited by Aux/IAA-mediated recruitment of the TPL co-repressor, closing the locus. As auxin levels rise (B), AFBs ubiquitinate Aux/IAAs, thereby allowing all transcription factors to act on the locus. As a result, there is a significant difference in gene expression between baseline and auxin induction. In afb1,2,3,4 mutants (C), Aux/IAAs are not degraded, and therefore the promoter remains closed. In the iaa2mDII degron mutant (D), one of three Aux/IAAs is stabilized, thereby resulting in only partial promoter closure. In arfasept lines, Aux/IAAs are not recruited to the promoter. While gene expression remains diminished without activating ARFs, other non-ARF transcription factors are allowed to provide baseline gene expression. However, there is no auxin-mediated induction.

🌱🧬 INSIGHT 🧬🌱 Complete loss of A-ARF activity in bryophytes reveals a role for auxin-adjacent regulatory networks – Flores-Sandoval & Bowman comment on an original research article by Bascom et al. 📝 Insight: doi.org/10.1093/jxb/... 🔬 Research: doi.org/10.1093/jxb/... #PlantScience 🧪
Fig. 1 (shortened, full legend in paper): Auxin responses and auxin-adjacent transcription factors (TFs) control developmental transitions in bryophyte gametophytes. (A) Wild-type (WT) auxin responses (left) cycling between low and high auxin. Under low auxin, A-ARFs are kept in a repressive complex by AUX/IAAs via recruitment of the TOPLESS co-repressor and associated histone deacetylases (HDACs). Under high auxin, auxin mediates the interaction between TIR1/AFB and AUX/IAAs, leading to AUX/IAA ubiquitination and proteolysis. A-ARFs are then free to interact with SWI/SNF ATPases and histone acetylases (HACs), leading to open chromatin states. Positive (TIR1/AFB, A-ARF, SWI/SNF, HAC), negative (AUX/IAA, TPL, HDAC) and auxin-adjacent (TFs) factors are shown. Auxin is represented by an A.
