Morpho Evo-Devo of the Gynoecium: Heterotopy, Redefinition of the Carpel, and a Topographic Approach [PDF]

open access: yesPlants
Since the 19th century, we have had countless debates, sometimes acrimonious, about the nature of the gynoecium. A pivotal question has been whether all angiosperms possess carpels or if some or all angiosperms are acarpellate.

The role of D3-type cyclins is related to cytokinin and the bHLH transcription factor SPATULA in Arabidopsis gynoecium development. [PDF]

open access: yesPlanta
We studied the D3-type cyclin function during gynoecium development in Arabidopsis and how they are related to the hormone cytokinin and the transcription factor SPATULA.

Flower and Spikelet Construction in Rapateaceae (Poales)

open access: yesFrontiers in Plant Science, 2022
The family Rapateaceae represents an early-divergent lineage of Poales with biotically pollinated showy flowers. We investigate developmental morphology and anatomy in all three subfamilies and five tribes of Rapateaceae to distinguish between ...

Auxin and the Arabidopsis thaliana gynoecium [PDF]

open access: yesJournal of Experimental Botany, 2013
Recent research is beginning to reveal how intricate networks of hormones and transcription factors coordinate the complex patterning of the gynoecium, the female reproductive structure of flowering plants. This review summarizes recent advances in understanding of how auxin biosynthesis, transport, and responses together generate specific gynoecial ...

Comparative Floral Morphology and Anatomy of Gagea s. str. and Lloydia

open access: yesActa Agrobotanica, 2021
Flowers of the five species from the four sections of the genus Gagea (that is, G. lutea, G. pusilla, G. reticulata, G. fragifera, and G. serotina (syn. Lloydia serotina) were investigated by light microscopy.

Organ symmetry establishment during gynoecium development

open access: hybridCurrent Opinion in Plant Biology
Symmetry is a key factor in the morphological diversity and reproductive success of angiosperms (flowering plants). The gynoecium, the female reproductive organ of the flower, displays remarkable variation in symmetry types, ranging from bilateral to radial, from its base (ovary) to its apex (style). Proper tissue growth and differentiation occur along

Refined Interpretation of the Pistillate Flower in Ceratophyllum Sheds Fresh Light on Gynoecium Evolution in Angiosperms

open access: yesFrontiers in Cell and Developmental Biology, 2022
Molecular phylogenetic analyses have revealed a superclade of mesangiosperms with five extant lineages: monocots, eudicots, magnoliids, Ceratophyllum and Chloranthaceae. Both Ceratophyllum and Chloranthaceae are ancient lineages with a long fossil record;

Plant Biology: Gynoecium Development with Style [PDF]

open access: yesCurrent Biology, 2020
The gynoecium is the female reproductive part of the flower and is essential for plant sexual reproduction. A new study shows a novel angiosperm-specific gene family that fine tunes the architecture of the stigma and style in Arabidopsis.
