Evolutionary history of the grass gynoecium
Journal of Experimental Botany, 2022 AbstractThe grass family (Poaceae) includes cereal crops that provide a key food source for the human population. The food industry uses the starch deposited in the cereal grain, which develops directly from the gynoecium. Morphological interpretation of the grass gynoecium remains controversial.

Plant 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 ...

AGAMOUS mediates timing of guard cell formation during gynoecium development
PLOS Genetics, 2023 AbstractInArabidopsis thaliana, stomata are composed of two guard cells that control the aperture of a central pore to facilitate gas exchange between the plant and its environment, which is particularly important during photosynthesis. Although leaves are the primary photosynthetic organs of higher plants, floral organs are also photosynthetically ...

Auxin regulation involved in gynoecium morphogenesis of papaya flowers [PDF]
Horticulture Research, 2019 AbstractThe morphogenesis of gynoecium is crucial for propagation and productivity of fruit crops. For trioecious papaya (Carica papaya), highly differentiated morphology of gynoecium in flowers of different sex types is controlled by gene networks and influenced by environmental factors, but the regulatory mechanism in gynoecium morphogenesis is ...

The effect of NGATHA altered activity in auxin signaling pathways within the Arabidopsis gynoecium [PDF]
Frontiers in Plant Science, 2014 The four NGATHA genes (NGA) form a small subfamily within the large family of B3-domain transcription factors of Arabidopsis thaliana. NGA genes act redundantly to direct the development of the apical tissues of the gynoecium, the style and the stigma ...

Expression of Ethylene Biosynthetic Genes in the Gynoecium and Receptacle Associated With Sepal Abscission During Senescence in Delphinium Grandiflorum [PDF]
, 2021 Delphinium flowers are highly sensitive to ethylene and its sepals abscise during senescence, which is associated with increases in 1-aminocyclopropane-1-carboxylic acid (ACC) synthase (ACS) and ACC oxidase (ACO) activities and ethylene production in ...

A high-resolution gene expression atlas of the medial and lateral domains of the gynoecium of Arabidopsis [PDF]
bioRxiv, 2023 Angiosperms are characterized by the formation of flowers, and in their inner floral whorl, one or various gynoecia are produced. These female reproductive structures are responsible for fruit and seed production, thus ensuring the reproductive ...
