Mutant analysis in a small weed reveals the blueprint of floral patterning

Abstract

Under the theme “Research that Transformed Developmental Biology”, this article discusses the seminal work by Bowman, Smyth, and Meyerowitz published in Development in 1991. The work laid down an elegant blueprint of flower patterning, namely the ABC model of flower development, which remains a cornerstone of plant development. In addition to summarizing key aspects of the model, the article emphasizes several noteworthy aspects, including the basic technique (mutant analysis) employed and the influence by animal development. Additionally, the article discusses significant follow-up research that confirmed key aspects of the model. Lastly, the article examines the impact of the ABC model on the field of plant EvoDevo. Collectively, the journey of how basic genetic analysis of mutants resulted in groundbreaking advancements in plant development will inspire future scientists and drive transformative research forward.
