MADS-box transcription factors are key regulators of several plant development processes. Analysis the complete Arabidopsis genome sequence revealed 107 genes encoding proteins, which 84% unknown function. Here, we provide a overview this family, describing gene structure, expression, localization, protein motif organization, and phylogenetic relationship each member. We have divided factor family into five groups (named MIKC, Malpha, Mbeta, Mgamma, Mdelta) based on relationships conserved...
Interactions between proteins are essential for their functioning and the biological processes they control. The elucidation of interaction maps based on yeast studies is a first step toward understanding molecular networks provides framework that possess capacity specificity to interact. Here, we present comprehensive plant protein-protein interactome map nearly all members Arabidopsis thaliana MADS box transcription factor family. A matrix-based two-hybrid screen >100 this family revealed...
Floral organs, whose identity is determined by specific combinations of homeotic genes, originate from a group undifferentiated cells called the floral meristem. In Arabidopsis, gene AGAMOUS (AG) terminates meristem activity and promotes development stamens carpels. To understand program expression activated AG, we followed genome-wide during early stamen carpel development. The AG target genes included most for which mutant screens revealed function downstream AG. Novel targets were...
Abstract TEOSINTE BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR1 (TCP) transcription factors control developmental processes in plants. The 24 TCP encoded the Arabidopsis (Arabidopsis thaliana) genome are divided into two classes, class I and II TCPs, which proposed to act antagonistically. We performed a detailed phenotypic analysis of tcp20 mutant, showing an increase leaf pavement cell sizes 10-d-old seedlings. Subsequently, glucocorticoid receptor induction assay was performed, aiming...
Plant MADS box proteins play important roles in a plethora of developmental processes. In order to regulate specific sets target genes, dimerize and are thought assemble into multimeric complexes. this study large-scale yeast three-hybrid screen is utilized provide insight the higher-order complex formation capacity Arabidopsis family. SEPALLATA3 (SEP3) has been shown mediate and, therefore, special attention paid factor study.In total, 106 complexes were identified; more than half these at...
Heavy metal hyperaccumulation in plants is an intriguing and poorly understood phenomenon. Transmembrane transporters are assumed to play a key role this process. We describe the cloning isolation of three zinc transporter cDNAs from Zn hyperaccumulator Thlaspi caerulescens. The ZTP1 gene highly similar Arabidopsis ZAT gene. Of other two, one most probably allele recently cloned ZNT1 T. caerulescens (Pence et al; Proceedings National Academy Science USA 97, 4956–4960, 2000). second, called...

Flowers are the most complex structures of plants. Studies Arabidopsis thaliana, which has typical eudicot flowers, have been fundamental in advancing structural and molecular understanding flower development. The main processes stages development summarized to provide a framework interpret detailed genetic studies genes assigned functions during is extended recent genomics uncovering key regulatory modules involved. Computational models used study concerted action dynamics gene module that...
Abstract The transition from vegetative to reproductive development is one of the most important phase changes in plant life cycle. This step controlled by various environmental signals that are integrated at molecular level so-called floral integrators. One such integrator Arabidopsis (Arabidopsis thaliana) MADS domain transcription factor SUPPRESSOR OF OVEREXPRESSION CONSTANS1 (SOC1). Despite extensive genetic studies, little known about transcriptional control SOC1, and we just starting...
Analyses of the functions TEOSINTE-LIKE1, CYCLOIDEA, and PROLIFERATING CELL FACTOR1 (TCP) transcription factors have been hampered by functional redundancy between its individual members. In general, putative functionally redundant genes are predicted based on sequence similarity confirmed genetic analysis. TCP family, however, identification is impeded relatively low overall similarity. a search for pairs that control Arabidopsis leaf development, this work performed an integrative...
Significance Seed desiccation tolerance (DT) is one of the most fascinating processes higher plants, and has played a fundamental role in evolution land plants. DT allows plant seeds to remain viable dry state for years even centuries. What key transcription factors (TFs) are that activate mechanisms allow maintain cellular DNA integrity centuries remains largely unknown. In this paper, we report identification TFs act as major nodes transcriptional networks regulate acquisition seed DT. We...
Summary Cytokinins have many essential roles in embryonic and post‐embryonic growth development, but their role fruit morphogenesis is currently not really known. Moreover, information about the spatio‐temporal localization pattern of cytokinin signaling gynoecia fruits lacking. Therefore, synthetic reporter line TCS::GFP was used to visualize during gynoecium development. Fluorescence detected at medial regions developing gynoecia, and, unexpectedly, valve margin fruits, severely altered...
Fruits and seeds are the major food source on earth. Both derive from gynoecium and, therefore, it is crucial to understand mechanisms that guide development of this organ angiosperm species. In Arabidopsis, composed two congenitally fused carpels, where domains: medial lateral, can be distinguished. The domain includes carpel margin meristem (CMM) key for production internal tissues involved in fertilization, such as septum, ovules, transmitting tract. Interestingly, shows a high cytokinin...
With growing populations and pressing environmental problems, future economies will be increasingly plant-based. Now is the time to reimagine plant science as a critical component of fundamental science, agriculture, stewardship, energy, technology healthcare. This effort requires conceptual technological framework identify map all cell types, comprehensively annotate localization organization molecules at cellular tissue levels. framework, called Plant Cell Atlas (PCA), for understanding...
Abstract Morphogenesis requires the coordination of cellular behaviors along developmental axes. In plants, gradients growth and differentiation are typically established a single longitudinal primordium axis to control global organ shape. Yet, it remains unclear how these locally adjusted regulate formation complex organs that consist diverse tissue types. Here we combine quantitative live imaging at resolution with genetics, chemical treatments understand Arabidopsis thaliana female...
Summary MADS‐domain transcription factors are essential for proper flower and seed development in angiosperms their role determination of floral organ identity can be described by the ‘ABC model’ development. Recently, close relatives B‐type genes were identified phylogenetic studies, which referred to as B sister (B s ) genes. Here, we report isolation characterization a MADS‐box member from petunia, designated FBP24 . An fbp24 knock‐down line appeared closely resemble Arabidopsis mutant...
Differentiation processes are responsible for the diversity and functional specialization of cell types that compose an organism. The outcome these can be studied at molecular, physiologic, biochemical levels by comparing different types, but complexity dynamics regulatory specify differentiation largely unexplored.Here we identified pollen-specific MIKC* class MADS-domain transcription factors as major regulators transcriptome during male reproductive development in Arabidopsis thaliana....
Abstract Synchronized communication between gametophytic and sporophytic tissue is crucial for successful reproduction, hormones seem to have a prominent role in it. Here, we studied the of Arabidopsis (Arabidopsis thaliana) cytochrome P450 CYP78A9 enzyme during reproductive development. First, controlled pollination experiments indicate that responds fertilization. Second, while overexpression can uncouple fruit development from fertilization, cyp78a8 cyp78a9 loss-of-function mutant has...
Grafting procedures are an excellent tool to study long range signalling processes within a plant. In the last decade, suitable flat-surface grafting for young Arabidopsis seedlings using collar support graft have been developed, allowing of long-range signals from molecular perspective.In modification presented here, scion and stock put together on medium without supporting elements, while cotyledons removed scion, resulting in increased success that can reach up 100%. At same time,...
