Understanding flower structure is important from many perspectives such as keying out plants, understanding fruit structure, investigating pollinator biology and in plant breeding. Probably the most complicated parts of a flower are the female components (the gynoecium). Unfortunately, in many parts of the world, it is not possible for much of the year

Repressed ethylene production in the gynoecium of long-lasting flowers of the carnation 'White Candle': role of the gynoecium in carnation flower senescence [PDF]
Journal of Experimental Botany, 2004 Ethylene production and expression of ethylene biosynthetic genes was investigated in senescing flowers of carnation (Dianthus caryophyllus L.) cultivars 'White Candle (WC)' and 'Light Pink Barbara (LPB)', with long and short vase-lives, respectively.

Discovery of Gynoecium Color Polymorphism in an Aquatic Plant
Journal of Integrative Plant Biology, 2008Abstract Flower color polymorphism exhibited by natural populations provides an opportunity for understanding the evolutionary mechanisms contributing to the diversity of floral morphology. However, little is known about the color polymorphism of female organs in flowering plants.

THE CACTUS GYNOECIUM: A NEW INTERPRETATION
American Journal of Botany, 1964Although taxonomists interpret the ovaries of most cacti as inferior,3 the inferior position has been derived in a very different manner from that in most flowering plants. In the classical situation, the dorsal sides of connate carpels arc invested by a floral tube (hypanthium) ; in Cactaceac, on the other hand, the dorsal sides of the carpels are ...

LEUNIG has multiple functions in gynoecium development inArabidopsis
genesis, 2000The Arabidopsis gene LEUNIG was previously found to regulate floral organ identity. In this work we describe gynoecial phenotypes of newly isolated strong leunig alleles, leunig-101, leunig-102, and leunig-103. Gynoecia of these strong leunig mutants are united only at the basal part, leaving four unfused parts at the apex.

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.

Development and evolution of the gynoecium in Myrteae (Myrtaceae)
Australian Journal of Botany, 2014Characters of the gynoecium are considered potentially significant for the systematics of Myrtaceae. However, only two such characters – ovule number and placentation – have been addressed from an evolutionary perspective. Colleter presence in flowers is a synapomorphy of Myrtales; however, no morphological and histochemical descriptions of such ...

Androecium and gynoecium anatomy of Bromeliaceae species
Flora, 2020Abstract In this study, we performed a detailed anatomical analysis of the androecium and gynoecium in 16 species belonging to three out of the eight Bromeliaceae subfamilies, with a first-time description of the interlocular zone in anthers, a diagnostic character for Quesnelia and Aechmea species. Other potential taxonomic characters were observed:

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

Morphology of the gynoecium and systematic position of the Ochnaceae
Botanical Journal of the Linnean Society, 1981The gynoecium is syncarpous in all Ochnaceae. In the Ochnoideae carpels are peltate with a conventional cross-zone bearing one ovule, or, in Lophira, a very broad cross-zone with an horizontal ovular row. In Ochna and Brackenridgea, the style is gynobasic, each carpel develops transmitting tissue on its morphologically dorsal surface, and this tissue ...
