Abstract
The terminal step of fruit development in
Arabidopsis
involves valve separation from the replum, allowing seed dispersal. This process requires the activities of the
SHATTERPROOF
MADS-box genes, which promote dehiscence zone differentiation at the valve/replum boundary. Here we show that the
FRUITFULL
MADS-box gene, which is necessary for fruit valve differentiation, is a negative regulator of
SHATTERPROOF
expression and that constitutive expression of
FRUITFULL
is sufficient to prevent formation of the dehiscence zone. Our studies suggest that ectopic expression of
FRUITFULL
may directly allow the control of pod shatter in oilseed crops such as canola.
