Origin of the angiosperm gynoecium by gamoheterotopy

Botanical Journal of the Linnean Society, 1988
Gamoheterotopy (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 ...

Gynoecium Structure and Evolution in Basal Angiosperms

International Journal of Plant Sciences, 2000
A 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.

Auxin and ETTIN in Arabidopsis gynoecium morphogenesis

Development, 2000
ABSTRACT The phytohormone auxin has wide-ranging effects on growth and development. Genetic and physiological approaches implicate auxin flux in determination of floral organ number and patterning. This study uses a novel technique of transiently applying a polar auxin transport inhibitor, N-1-naphthylphthalamic acid (NPA), to developing

Floral development of Gonocaryum with emphasis on the gynoecium

Plant Systematics and Evolution, 2017
We investigated the floral development of Gonocaryum, a genus of Cardiopteridaceae that was segregated from Icacinaceae s.l., using scanning electron microscopy to clarify its gynoecial structure and facilitate morphological comparisons of Cardiopteridaceae.

HISTOGENESIS OF THE ANDROECIUM AND GYNOECIUM IN DOWNINGIA BACIGALUPII

American Journal of Botany, 1968
A histogenetic investigation of the synandrous androecium and syncarpous gynoecium in the flower of Downingia bacigalupii Weiler (Campanulaceae; Lobelioideae) was undertaken for the purpose of comparing the modes of initiation, early growth and fusion in these floral whorls with that reported

Gynoecium and perianth inZanthoxylum s.l. (Rutaceae)

Plant Systematics and Evolution, 1994
The 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.

Protein- hormone interactions patterning the gynoecium [PDF]

, 2015
The gynoecium is among the most intricately patterned organs of the plant, comprisingdifferent tissue sub-structures, all with the purpose of facilitating propagation to the next generation. It is therefore representative of the complexity involved in the initiation and establishment of organ patterning and presents a unique model to study the ...
