Gene networks controlling petal organogenesis

J Exp Bot. 2016 Jan;67(1):61-8. doi: 10.1093/jxb/erv444. Epub 2015 Oct 1.

Abstract

One of the biggest unanswered questions in developmental biology is how growth is controlled. Petals are an excellent organ system for investigating growth control in plants: petals are dispensable, have a simple structure, and are largely refractory to environmental perturbations that can alter their size and shape. In recent studies, a number of genes controlling petal growth have been identified. The overall picture of how such genes function in petal organogenesis is beginning to be elucidated. This review will focus on studies using petals as a model system to explore the underlying gene networks that control organ initiation, growth, and final organ morphology.

Keywords: Arabidopsis; cell differentiation; cell division; cell expansion; gene networks; petal organogenesis..
