Divergence of function and regulation of class B floral organ identity genes. [PDF]

The Plant Cell, 1997
Regulatory mechanisms controlling basic aspects of floral morphogenesis seem to be highly conserved among plant species. The class B organ identity genes, which are required to establish the identity of organs in the second (petals) and third (stamens) floral whorls, are a good example of such conservation.

Functional analysis of B and C class floral organ genes in spinach demonstrates their role in sexual dimorphism

BMC Plant Biology, 2010
Background Evolution of unisexual flowers entails one of the most extreme changes in plant development. Cultivated spinach, Spinacia oleracea L., is uniquely suited for the study of unisexual flower development as it is dioecious and it achieves ...

OsMADS1 represses microRNA172 in elongation of palea/lemma development in Rice

Frontiers in Plant Science, 2016
Specification of floral organ identity is critical for the establishment of floral morphology and inflorescence architecture. Although multiple genes are involved in the regulation of floral organogenesis, our understanding of the underlying regulating ...

The SEP4 Gene of Arabidopsis thaliana Functions in Floral Organ and Meristem Identity [PDF]

Current Biology, 2004
The ABC model of flower organ identity is widely recognized as providing a framework for understanding the specification of flower organs in diverse plant species. Recent studies in Arabidopsis thaliana have shown that three closely related MADS-box genes, SEPALLATA1 (SEP1), SEP2 and SEP3, are required to specify petals, stamens, and carpels because ...

Expression and Functional Analyses of Nymphaea caerulea MADS-Box Genes Contribute to Clarify the Complex Flower Patterning of Water Lilies

Frontiers in Plant Science, 2021
Nymphaeaceae are early diverging angiosperms with large flowers characterized by showy petals and stamens not clearly whorled but presenting a gradual morphological transition from the outer elements to the inner stamens.

SLL1-ZH Regulates Spikelets Architecture and Grain Yield in Rice

Agriculture, 2021
The spikelet developmental processes that control structure and floral organ identity play critical roles in rice grain yield formation. In this study, we characterized a novel rice mutant, SLL1-ZH, which exhibits a variety of defective agronomic ...

AGAMOUS AND TERMINAL FLOWER controls floral organ identity and inflorescence development in Medicago truncatula.

Journal of Integrative Plant Biology, 2019
Angiosperms integrate a multitude of endogenous and environmental signals to control floral development, thereby ensuring reproductive success. Here, we report the identification of AGAMOUS AND TERMINAL FLOWER (AGTFL), a novel regulator of floral ...

Combined genome-wide association studies and expression quantitative trait locus analysis uncovers a genetic regulatory network of floral organ number in a tree peony (Paeonia suffruticosa Andrews) breeding population

Horticulture Research, 2023
Great progress has been made in our understanding of floral organ identity determination and its regulatory network in many species; however, the quantitative genetic basis of floral organ number variation is far less well understood for species-specific

Floral organ size control [PDF]

Plant Signaling & Behavior, 2009
Growth of lateral organs is a complex mechanism that starts with formation of lateral primordia. Basal developmental programs like polarity, organ identity and environmental cues influence the final organ size achieved via coordinated cell division and expansion.

LEAFY and Polar Auxin Transport Coordinately Regulate Arabidopsis Flower Development

Plants, 2014
The plant specific transcription factor LEAFY (LFY) plays a pivotal role in the developmental switch to floral meristem identity in Arabidopsis. Our recent study revealed that LFY additionally acts downstream of AUXIN RESPONSE FACTOR5/MONOPTEROS to ...
