Comparative gynoecium morphology in Stratiotes aloides L. and Hydrocharis morsus-ranae L. (Hydrocharitaceae)

open access: yesБіологічні студії, 2010
Comparative morphology and vascularisation of the gynoecium in Stratiotes aloides and Hydrocharis morsus-ranae hare been studied. The gynoecium is syncarpous, with synascidiate, symplicate, hemisymplicate and asymplicate zones, first three zones are ...

The syncarpous gynoecium [PDF]

open access: yesNew Zealand Journal of Botany, 1978
Abstract Recent proposals to extend the concept of the acarpellary gynoecium to most syncarpous ovaries are examined. It is concluded that the morphogenesis of these ovaries is compatible with the classical interpretation of fused carpels, and that the arguments for the alternative interpretation of them as acarpellary structures are inconclusive.

A Model for an Early Role of Auxin in Arabidopsis Gynoecium Morphogenesis

open access: yesFrontiers in Plant Science, 2014
The female reproductive organ of the angiosperm, the gynoecium, often consists of the fusion of multiple ovule-bearing carpels. It serves to produce and protect ovules and mediate pollination.

Evidence for the Regulation of Gynoecium Morphogenesis by ETTIN via Cell Wall Dynamics

open access: greenPlant Physiology, 2018
ETTIN, a transcription factor also known as Auxin Response Factor 3, enhances PME activity in the valve tissue, thus maintaining low cell wall stiffness and proper gynoecium morphogenesis.

Gynoecium diversity and systematics of the Laurales [PDF]

open access: yesBotanical Journal of the Linnean Society, 1997
Carpel and ovule structure was comparatively studied in representatives of all eight families of the Laurales: Amborellaceae, Calycanthaceae, Chloranthaceae, Gomortegaceae,Hernandiaceae, Lauraceae, Monimiaceae, and Trimeniaceae. In all representatives the carpels are closed at anthesis.

Morphological and taxonomical treatments of fruits in the subclass Rosidae Takht. of the flora of Ukraine

open access: yesБіологічні студії, 2023
Introduction. Rosids is the pivotal clade of eudicots, whose taxonomic composition was significantly changed based on molecular phylogeny. Molecular insight led to the re-evaluation of many phenotypic features, especially in reproductive morpho­logy ...

B-Function Expression in the Flower Center Underlies the Homeotic Phenotype of Lacandonia schismatica (Triuridaceae) [PDF]

open access: yes, 2010
Spontaneous homeotic transformations have been described in natural populations of both plants and animals, but little is known about the molecular-genetic mechanisms underlying these processes in plants.

Evolution of Sex Chromosomes and Gynoecium Suppression in Plants

open access: yesCYTOLOGIA, 2023
White campion (Silene latifolia, Caryophyllaceae) is a classical model species for studies of sex determination and sex chromosome evolution in dioecious plants. Deletion mapping in this species revealed the presence of two Y-linked sex determining genes—the stamen promoting factor (SPF) gene and a gynoecium suppressing factor (GSF), which ...

Copper deficiency alters shoot architecture and reduces fertility of both gynoecium and androecium in Arabidopsis thaliana

open access: yesbioRxiv, 2020
Copper deficiency reduces plant growth, male fertility and seed set. The contribution of copper to female fertility and the underlying molecular aspects of copper deficiency-caused phenotypes are not well-known.
