Idan Efroni @idane.bsky.social · 17/03/2026As for 2, I agree that’s a drawback at the moment - but we are working on a way to do that. Won’t rerun the pipeline (too computationally intensive) but transferring CNS annotations from a close genome. 150
Idan Efroni @idane.bsky.social · 17/03/2026Good point. We saw that developmental genes and TFs tend to have long and complicated regulatory regions. Enzymes, photosynthesis, structural genes, tend to be shorter and less conserved (general trend - exceptions exist). Our focus on development could bias our experience. 031
Idan Efroni @idane.bsky.social · 17/03/2026In our hands, this is rarely the case. Easier to get arabidopsis upstream sequences to work in tomato vs the opposite. Case in point- how many tomato developmental reporters are there? I interpret complementation being partial, as proximal promotors promoting some expression, but not the real one. 100
Idan Efroni @idane.bsky.social · 17/03/2026That is mostly true for Arabidopsis, which has a very compact genome. In other plants, like tomato, for example, we have mostly failures. Also, it is not so easy to determine how precise is the reporter compared to the actual gene expression. Complementation is often only partial. 130

Idan Efroni @idane.bsky.social · 11/12/2023This transient isolation of regenerating cells is mediated by the LATERAL ORGAN BOUNDARY (LBD) transcription factors, which are involved in many plant developmental processes. This is mainly the long and hard work of Itay Cohen with fantastic help from @zivirus.bsky.social and Emmanuelle Bayer. 151
Idan Efroni @idane.bsky.social · 11/12/2023Plant cells know what type to be based on signals they receive from their neighbors. When you cut the root, existing cells rapidly replace the missing tissues, yet neighbors persist... We show that cells must transiently disconnect in order to regenerate. www.biorxiv.org/content/10.1... 1155
