Led by Wenye Lin, a doctoral student in Kierzkowski’s lab, the new study lays the groundwork for understanding leaf morphogenesis in the moss Physcomitrium patens, highlighting both the anatomical simplicity of its leaves and their surprising morphological similarities to those of flowering plants.<\/p>\n
To carry out the research, the Kierzkowski lab leveraged a novel methodological approach of real-time imaging, combining it with genetics and computational modeling. The latter technique involves virtually simulating leaf growth from real data, making it possible to test hypotheses and predict cellular behaviors before reproducing them in the laboratory \u2014 akin to a digital model of living matter.<\/p>\n
The work was carried out in close collaboration with Yoan Coudert of the \u00c9cole Normale Sup\u00e9rieure de Lyon (France) for the genetic component, and Richard Smith of the John Innes Centre (United Kingdom) for the computational modeling.<\/p>\n
The single-cell-layer structure of moss leaves offers a unique opportunity to quantify the development of an entire organ from a single founder cell \u2014 something difficult to achieve in flowering plants, the researchers say.<\/p>\n
This privileged observation window allowed Kierzkowski and his colleagues to demonstrate how deeply shared developmental principles govern leaf growth across plant lineages separated by hundreds of millions of years of evolution.<\/p>\n
In the end, they say, their research amounts to an advance that repositions moss as an essential model organism for deciphering the universal laws of plant morphogenesis.<\/p>\n","protected":false},"excerpt":{"rendered":"Led by Wenye Lin, a doctoral student in Kierzkowski’s lab, the new study lays the groundwork for understanding…\n","protected":false},"author":2,"featured_media":618182,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[13927,49,48,11242,232212,109787,109785,109786,232213,232214,994,66],"class_list":{"0":"post-618181","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-science","8":"tag-biology","9":"tag-ca","10":"tag-canada","11":"tag-cell","12":"tag-daniel-kierzkowski","13":"tag-department-of-biological-sciences","14":"tag-faculty-of-arts-and-sciences","15":"tag-fas","16":"tag-institut-de-recherche-en-biologie-vegetale","17":"tag-irbv","18":"tag-research","19":"tag-science"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/618181","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=618181"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/618181\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/618182"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=618181"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=618181"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=618181"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
