{"issue":"4","publication_status":"published","publication":"Current Biology","abstract":[{"lang":"eng","text":"Plants form new organs with patterned tissue organization throughout their lifespan. It is unknown whether this robust post-embryonic organ formation results from stereotypic dynamic processes, in which the arrangement of cells follows rigid rules. Here, we combine modeling with empirical observations of whole-organ development to identify the principles governing lateral root formation in Arabidopsis. Lateral roots derive from a small pool of founder cells in which some take a dominant role as seen by lineage tracing. The first division of the founders is asymmetric, tightly regulated, and determines the formation of a layered structure. Whereas the pattern of subsequent cell divisions is not stereotypic between different samples, it is characterized by a regular switch in division plane orientation. This switch is also necessary for the appearance of patterned layers as a result of the apical growth of the primordium. Our data suggest that lateral root morphogenesis is based on a limited set of rules. They determine cell growth and division orientation. The organ-level coupling of the cell behavior ensures the emergence of the lateral root's characteristic features. We propose that self-organizing, non-deterministic modes of development account for the robustness of plant organ morphogenesis."}],"_id":"526","author":[{"id":"49E91952-F248-11E8-B48F-1D18A9856A87","last_name":"Von Wangenheim","orcid":"0000-0002-6862-1247","first_name":"Daniel","full_name":"Daniel von Wangenheim"},{"last_name":"Fangerau","first_name":"Jens","full_name":"Fangerau, Jens"},{"last_name":"Schmitz","full_name":"Schmitz, Alexander","first_name":"Alexander"},{"last_name":"Smith","first_name":"Richard","full_name":"Smith, Richard S"},{"last_name":"Leitte","first_name":"Heike","full_name":"Leitte, Heike"},{"last_name":"Stelzer","first_name":"Ernst","full_name":"Stelzer, Ernst H"},{"last_name":"Maizel","first_name":"Alexis","full_name":"Maizel, Alexis"}],"doi":"10.1016/j.cub.2015.12.047","quality_controlled":0,"title":"Rules and self-organizing properties of post-embryonic plant organ cell division patterns","intvolume":"        26","date_updated":"2021-01-12T08:01:24Z","publist_id":"7293","volume":26,"extern":1,"type":"journal_article","date_published":"2016-02-22T00:00:00Z","status":"public","year":"2016","publisher":"Cell Press","page":"439 - 449","day":"22","citation":{"ieee":"D. von Wangenheim <i>et al.</i>, “Rules and self-organizing properties of post-embryonic plant organ cell division patterns,” <i>Current Biology</i>, vol. 26, no. 4.
