Genetic interaction between AINTEGUMENTA ( ANT) and the ovule identity genes SEEDSTICK ( STK), SHATTERPROOF1 ( SHP1) and SHATTERPROOF2 ( SHP2).

AINTEGUMENTA ( ANT) promotes initiation and growth of ovule integuments which cell fate is specified by ovule identity factors, such as SEEDSTICK ( STK), SHATTERPROOF1 ( SHP1) and SHATTERPROOF2 ( SHP2). To study the genetic interaction between ANT and the ovule identity genes, we have obtained a stk shp1 shp2 ant quadruple mutant. The molecular and morphological characterization of the quadruple mutant and its comparison with the stk shp1 shp2 triple mutant, the shp1 shp2 ant triple mutant and the stk ant double mutant are here presented.
