F-Box蛋白Unusual Floral Organs (UFO)是SKP1-Cullin1-F-box (SCF)E3 泛素连接酶 复合体的接头蛋白（adaptor）。 LFY与UFO协同调控花器官发育，但其分子机制并不清楚。 近日，来自法国的研究团队在 Nature Plants 在线发表了题为“ The F-box protein UFO controls flower development by redirecting the master transcription factor LEAFY to new cis-elements ”的研究论文。
Flower | Definition, Parts, Anatomy, Types,& Facts | Britannica
2024年12月9日 · Basically, each flower consists of a floral axis upon which are borne the essential organs of reproduction (stamens and pistils) and usually accessory organs (sepals and petals); the latter may serve to both attract pollinating insects and protect the essential organs.
The development of flower organs is determined by organ characteristic genes and influenced by various regulatory mechanisms. Floral organ-specific ABCDE genes are mostly
Formation of Floral Organs | Flowers - Biology Discussion
The formation of flower or an inflorescence occurs during and after the transition of shoot apex to flowering phase. The introduction of scan electron microscope has greatly advanced the study of development of floral organs in a flower and floral primordia in an inflorescence.
ABC model of flower development - Wikipedia
The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
‘Organ’ising Floral Organ Development - MDPI
2024年6月8日 · Flowers are plant structures characteristic of the phylum Angiosperms composed of organs thought to have emerged from homologous structures to leaves in order to specialize in a distinctive function: reproduction. Symmetric shapes, colours, and scents all play important functional roles in flower biology.
Flower - Wikipedia
A flower, also known as a bloom or blossom, [1] is the reproductive structure found in flowering plants (plants of the division Angiospermae).Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower. Petals attract pollinators, and reproductive organs that produce gametophytes, which in flowering plants produce gametes.
The Evolution of Diverse Floral Morphologies - ScienceDirect
2017年9月11日 · In this review, we explore the evolution of floral diversity, focusing on our recent understanding of the mechanistic basis of evolutionary change. We discuss the various ways in which flower size and floral organ size can be modified, the means by which flower shape and symmetry can change, and the ways in which floral organ position can be ...
Floral quartets - Nature
2001年1月25日 · According to this model, the identity of the different floral organs — sepals, petals, stamens and carpels — is determined by four combinations of floral homeotic proteins known as MADS-box ...
Floral Organs - BrainKart
Flowers are complex structures that consist of several organ types borne on a central axis (the receptacle). In many species each flower is subtended by a modified leaf-like structure termed a bract (Fig. 1.2), though bracts are absent from some other species.
