Control of organ size in plants
WebJul 29, 2008 · The growth rate and final size of plant organs is determined by both genetic constraints and environmental factors. Regulatory inputs act at two control points: on proliferation; and on the transition between proliferation and differentiation.

Although the size of an organism is a defining feature, little is known about the mechanisms that set the final size of organs and whole organisms. Here we describe Arabidopsis DA1, encoding a predicted ubiquitin receptor, which sets final seed and organ size by restricting the period of cell proliferation.

Plant organs grow to highly reproducible sizes that are determined by the plant's genotype and by the identity of the organ. The strong heritability of size differences indicates that organ size is under tight genetic control. The overall increase in size of plant organs is driven by two distinct processes: cell proliferation with the ...
