The AGL11 MADS-box gene is preferentially expressed in developing ovules. AGL11 is similar in sequence to AGAMOUS, AGL1, and AGL5, all of which show overlapping patterns of expression during carpel and ovule development. AGL11 is the likely ortholog of the FBP7/FBP11 pair of MADS-box genes from petunia, which have been shown to play roles during ovule and seed development.


Gene Sequence

Map position

AGL11 RNA begins to accumulate during stage 9 of flower development, where its expression is localized in carpels to the placental tissues from which ovules will arise.

Expression continues during ovule development, where the highest levels of AGL11 RNA are restricted to the chalazal end of the ovule, the outer integument, and the funiculus.
