Redundant and Non-redundant Functions of the AHK Cytokinin Receptors During Gynoecium Development

Frontiers in Plant Science, 2020
The phytohormone cytokinin is crucial for plant growth and development. The site of action of cytokinin in the plant is dependent on the expression of the cytokinin receptors.

Time-lapse confocal imaging helps to reveal a secret behind gynoecium development [PDF]

Quantitative Plant Biology
Organ morphogenesis is a complex process and numerous factors must be considered while choosing a method for its quantitative investigation. Few methods facilitate in vivo imaging.

The bHLH transcription factor SPATULA enables cytokinin signaling, and both activate auxin biosynthesis and transport genes at the medial domain of the gynoecium [PDF]

PLoS Genetics, 2017
Fruits and seeds are the major food source on earth. Both derive from the gynoecium and, therefore, it is crucial to understand the mechanisms that guide the development of this organ of angiosperm species.

Exploring Cell Wall Composition and Modifications During the Development of the Gynoecium Medial Domain in Arabidopsis

Frontiers in Plant Science, 2018
In Arabidopsis, the gynoecium, the inner whorl of the flower, is the female reproductive part. Many tissues important for fertilization such as the stigma, style, transmitting tract, placenta, ovules, and septum, comprising the medial domain, arise from ...

Morpho-Anatomy of the Gynoecium and Fruit in Three Ornamental Members of Campanuloideae (Campanulaceae)

Acta Agrobotanica, 2021
Gynoecium and fruit micromorphology and anatomy were studied using light microscopy in three species of Campanuloideae belonging to the tribes Cyanantheae (Platycodon grandiflorus), Wahlenbergieae (Jasione montana), and Campanuleae (Adenophora liliifolia)

Cytokinin treatments affect the apical-basal patterning of the Arabidopsis gynoecium and resemble the effects of polar auxin transport inhibition [PDF]

Frontiers in Plant Science, 2014
The apical-basal axis of the Arabidopsis gynoecium is established early during development and is divided into four elements from the bottom to the top: the gynophore, the ovary, the style, and the stigma. Currently, it is proposed that the hormone auxin

Phylogenetic Relatedness Determines Heterospecific Pollen-Pistil Compatibility and Reproductive Outcome in the Apocarpous Species <i>Sagittaria trifolia</i> (Alismataceae). [PDF]

Ecol Evol
This study investigates heterospecific pollen (HP) effects in Sagittaria trifolia, an apocarpous plant with an extragynoecial compitum. HP–pistil compatibility and resulting seed set reduction were greatest from phylogenetically close donors, not influenced by origin or pollen traits.

Floral stage optimization and immune evasion enhance Agrobacterium-mediated genome editing in Arabidopsis. [PDF]

New Phytol
Summary Agrobacterium‐mediated transformation by floral inoculation (AMT‐FI) enables genetic engineering without tissue culture. It is widely used in the model plant Arabidopsis thaliana, yet its efficiency and broader applicability remain limited. Here, we used a dual‐reporter system (RUBY and hygromycin resistance) to identify key floral stages and ...

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 [PDF]

Acta 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.

The gynoecium comparative morphology of some representatives of Ornithogaloideae (Hyacinthaceae)

Біологічні студії, 2018
The gynoecium micromorphology of Dipcadi brevifolium (Dipcadieae, Ornithogaloideae), Ornithogalum fimbriatum, Ornithogalum dubium, Ornithogalum orthophyllum subsp. kochii (Ornithogaleae, Ornithogaloideae) was studied. Three main parts of the ovary of the
