An evo-devo view of the gynoecium

open access: yesJournal of Experimental Botany, 2023
Abstract The appearance of the flower marks a key event in the evolutionary history of plants. Among the four types of floral organs, the gynoecium represents the major adaptive advantage of the flower. The gynoecium is an enclosing structure that protects and facilitates the fertilization of the ovules, which then mature as seeds.

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 ...

Gynoecium and fruit development in Arabidopsis

open access: yesDevelopment, 2022
ABSTRACT Flowering plants produce flowers and one of the most complex floral structures is the pistil or the gynoecium. All the floral organs differentiate from the floral meristem. Various reviews exist on molecular mechanisms controlling reproductive development, but most focus on a short time window and there has been no recent review

Gynoecium diversity and systematics of the paleoherbs [PDF]

open access: yesBotanical Journal of the Linnean Society, 1998
Gynoecium and ovule structure was compared in representatives of all families of the paleoherbs, including Nymphaeales (Cabombaceae, Nymphaeaceae), Piperales (Saururaceae, Piperaceae), Aristolochiales (Lactoridaceae, Aristolochiaceae), Rafflesiales (Hydnoraceae, Rafflesiaceae) and, in addition, Ceratophyllaceae and Nelumbonaceae, both of which were ...

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.

The gynoecium structure in Dracaena fragrans (L.) Ker Gawl., Sansevieria parva N.E. Brown and S. trifasciata Prain (Asparagaceae) with special emphasis on the structure of the septal nectary

open access: yesActa Agrobotanica, 2014
In the gynoecium of Dracaena fragrans, Sansevieria parva and S. trifasciata, the vertical zonality of the ovary, the structural zonality of the gynoecium following Leinfellner, and the zonality of the septal nectary were studied.

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 ...

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 ...

Morphology and vascular anatomyof Galtonia viridiflora I. Verd. (Hyacinthaceae) flower

open access: yesБіологічні студії, 2014
The morphology and vascular anatomy of the flower of Galtonia viridiflora I. Verd. (Ornithogaloideae, Hyacinthaceae) were studied. Each of tepals, and each stamen is supplied by single vascular bundle.

Unique and overlapping functions for the transcriptional regulators KANADI1 and ULTRAPETALA1 in Arabidopsis gynoecium and stamen gene regulation

open access: yesPlant Direct, 2023
Plants generate their reproductive organs, the stamens and the carpels, de novo within the flowers that form when the plant reaches maturity. The carpels comprise the female reproductive organ, the gynoecium, a complex organ that develops along several ...
