Diversity in leaf shape is produced by alterations of the margin: for example, deep dissection leads to leaflet formation and less-pronounced incision results serrations or lobes. By combining gene silencing mutant analyses four distantly related eudicot species, we show that reducing function NAM/CUC boundary genes (NO APICAL MERISTEM CUP-SHAPED COTYLEDON) a suppression all marginal outgrowths fewer fused leaflets. We propose promote domain delimits This has dual role promoting separation...
The evolution of plant reproductive strategies has led to a remarkable diversity structures, especially within the flower, structure characteristic angiosperms. In flowering plants, sexual reproduction depends notably on development gynoecium that produces and protects ovules. Arabidopsis thaliana, ovule initiation is promoted by concerted action auxin with CUC1 (CUP-SHAPED COTYLEDON1) CUC2, two genes encode transcription factors NAC family (NAM/ATAF1,2/CUC). Here we highlight an additional...
Abstract Angiosperms are the most diverse and numerous group of plants, it is generally accepted that this evolutionary success owes in part to diversity found fruits, key for protecting developing seeds ensuring seed dispersal. Although studies on molecular basis morphological innovations few, they all illustrate central role played by transcription factors acting as developmental regulators. Here, we show a small change protein sequence MADS-box factor correlates with origin highly...
The ABC model is widely used as a genetic framework for understanding floral development and evolution. In this model, the A-function required of sepals petals to antagonize C-function in outer whorls. rosid species Arabidopsis thaliana, AP2-type AP2 transcription factor represents major protein, but how encoded other not well understood. Here, we show that asterid petunia (Petunia hybrida), AP2B/BLIND ENHANCER (BEN) confines inner whorls, parallel with microRNA BLINDBEN belongs TOE-type...
The closely related NAC family genes NO APICAL MERISTEM (NAM) and CUP-SHAPED COTYLEDON3 (CUC3) regulate the formation of boundaries within between plant organs. NAM is post-transcriptionally regulated by miR164, whereas CUC3 not. To gain insight into evolution in angiosperms, we analysed orthologous early-diverging ANA-grade angiosperms gymnosperms. We obtained NAM- CUC3-like sequences from diverse gymnosperms a combination reverse transcriptase PCR, cDNA library screening database...
MicroRNAs (miRNAs) control many important aspects of plant development, suggesting these molecules may also have played key roles in the evolution developmental processes plants. However, evolutionary-developmental (evo-devo) studies miRNAs been held back by technical difficulties gene identification. To help solve this problem, we developed a two-step procedure for efficient identification miRNA genes any species. As test case, studied MIR164 family angiosperms. We identified novel three...
The majority of angiosperms are syncarpous- their gynoecium is composed two or more fused carpels. In Arabidopsis thaliana, this fusion regulated through the balance expression between CUP SHAPED COTYLEDON (CUC) genes, which orthologues Petunia hybrida transcription factor NO APICAL MERISTEM (NAM), and post-transcriptional regulator miR164. Accordingly, a miR164-insensitive form Ar. thaliana CUC2 causes radical breakdown carpel fusion. Here, we investigate role NAM/miR164 genetic module in...
Abstract Robustness is pervasive throughout biological systems, enabling them to maintain persistent outputs despite perturbations in their components. Here, we reveal a mechanism contributing leaf morphology robustness the face of genetic perturbations. In Arabidopsis (Arabidopsis thaliana), shape established during early development through quantitative action CUP-SHAPED COTYLEDON2 (CUC2) protein, whose encoding gene negatively regulated by co-expressed MICRORNA164A (MIR164A) gene....
We provide an overview of methods and workflows that can be used to investigate the topologies Gene Regulatory Networks (GRNs) in context plant evolutionary-developmental (evo-devo) biology. Many species occupy key positions phylogeny are poorly adapted as laboratory models so we focus here on techniques efficiently applied both model non-model interest evo-devo. outline describe gene expression patterns also elucidate transcriptional, post-transcriptional, epigenetic regulatory mechanisms...
