Inferences on gynoecium evolution in Xyris (Xyridaceae, Poales) based on floral anatomy and development

, 2021
The floral anatomy and development of species belonging to all sections of Xyris (Xyris, Nematopus and Pomatoxyris) were investigated comparatively to elucidate gynoecium evolution in the genus, because placentation has been one of the key characters ...

Inside the gynoecium: at the carpel margin

Trends in Plant Science, 2013
The gynoecium, which is produced at the center of most flowers, is the female reproductive organ and consists of one or more carpels. The Arabidopsis gynoecium consists of two fused carpels. Its inner tissues possess meristematic characteristics and are called the carpel margin meristem (CMM), because they are located at the margins of the carpels and ...

Arabidopsis transcription factor TCP4 controls the identity of the apical gynoecium.

The Plant Cell
The style and stigma at the apical gynoecium are crucial for flowering plant reproduction. However, the mechanisms underlying specification of the apical gynoecium remain unclear. Here, we demonstrate that Class II TEOSINTE BRANCHED 1/CYCLOIDEA/PCF (TCP)

LEUNIG has multiple functions in gynoecium development inArabidopsis

genesis, 2000
The 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.

A Comparative Ontogenetic Approach to Understanding the Pseudomonomerous Gynoecium in Moraceae

INTERNATIONAL JOURNAL PLANT SCIENCES, 2020
Premise of research. Moraceae, the well-known mulberry or fig family, displays small, inconspicuous, diclinous flowers that are very different from many other rosids.

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

Gynoecium structure and development in core Caryophyllales: a matter of proportions

, 2020
This review based on a morphological and developmental perspective reveals a striking diversity in shapes and evolutionary trends in the gynoecium of core Caryophyllales that have affected the number of carpels, the formation of septa and the number of

THE CACTUS GYNOECIUM: A NEW INTERPRETATION

American Journal of Botany, 1964
Although 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 ...

Discovery of Gynoecium Color Polymorphism in an Aquatic Plant

Journal of Integrative Plant Biology, 2008
Abstract 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.

A guide to the gynoecium

Journal of Biological Education, 2010
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
