IS THE GRASS GYNOECIUM MONOCARPELLARY?
American Journal of Botany, 1985Two interpretations are currently applied to the gynoecium of the Gramineae. Either it is monocarpellary or it is syncarpous (pseudomonocarpellary). These two views are examined and it is concluded that the grass gynoecium retains features of a tricarpellary ancestry.

Molecular genetics of gynoecium development in Arabidopsis.
Current topics in developmental biology, 1999Carpels are the ovule-bearing structural units in angiosperms. In Arabidopsis, the specification of carpel identity is achieved by at least two separate pathways: a pathway mediated by the C class gene AG and an AG-independent pathway. Both pathways are negatively regulated by A class genes. Two genes, SPT and CRC, can promote differentiation of carpel

Gynoecium and perianth inZanthoxylum s.l. (Rutaceae)
Plant Systematics and Evolution, 1994The question whether the uniseriate perianth ofZanthoxylum L. s. str. is homologous with the calyx or the corolla of taxa included inFagara, or of an independent origin, has been controversial for a long time, but the arguments mostly have remained theoretical.

Gynoecium Structure and Evolution in Basal Angiosperms
International Journal of Plant Sciences, 2000A comparative study on gynoecium structure in basal angiosperms revealed new features relevant to systematics. In addition, based on the new phylogenetic framework on basal angiosperms gained by molecular systematics, an evolutionary evaluation of gynoecial character states has become possible.

Origin of the angiosperm gynoecium by gamoheterotopy
Botanical Journal of the Linnean Society, 1988Gamoheterotopy (the transfer of characters from one sex to another) is very common in animals, and it is quite possible that it also played an important role in the evolution of plant fructifications. The gamoheterotopic origin of the angiosperm gynoecium by a transfer of the bennettitalean microsporophyll structure to the seed-bearing organ is ...

Morphology of the gynoecium in Labiatae
1982Two gynoecial primordia are initiated as discrete units but soon get interconnected by the occurrence of interprimordial growth between them. A rim of meristematic tissue thus produced gives rise to the ovary wall by zonal growth. The residual floral apex grows parallel to the gynoecial primordia in the form of a septum.
