Download or read book Plant Development Role of Gene Regulatory Networks written by Isabel Nelson and published by States Academic Press. This book was released on 2021-11-16 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene regulatory networks are composed of molecular regulators such as transcription factors which bind short, non-coding DNA sequences. These sequences are also called cis-regulatory elements and are located in the promoter region of a gene. Transcription regulators form an interconnected regulatory network which integrates endogenous and environmental signals into changes in gene expression. Gene regulatory networks provide an insight about organization of plant cells and their functions. They consist of thousands of connections between the target genes and transcription factors. Together, they regulate many cellular functions. They also help in understanding the regulation of genes under various conditions. The book studies, analyses and upholds the pillars of gene regulatory networks and its utmost significance in modern times. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included herein. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of the subject.
Download or read book Evolution of Gene Regulatory Networks in Plant Development written by Federico Valverde and published by Frontiers Media SA. This book was released on 2018-02-15 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: During their life cycle plants undergo a wide variety of morphological and developmental changes. Impinging these developmental processes there is a layer of gene, protein and metabolic networks that are responsible for the initiation of the correct developmental transitions at the right time of the year to ensure plant life success. New omic technologies are allowing the acquisition of massive amount of data to develop holistic and integrative analysis to understand complex processes. Among them, Microarray, Next-generation Sequencing (NGS) and Proteomics are providing enormous amount of data from different plant species and developmental stages, thus allowing the analysis of gene networks globally. Besides, the comparison of molecular networks from different species is providing information on their evolutionary history, shedding light on the origin of many key genes/proteins. Moreover, developmental processes are not only genetically programed but are also affected by internal and external signals. Metabolism, light, hormone action, temperature, biotic and abiotic stresses, etc. have a deep effect on developmental programs. The interface and interplay between these internal and external circuits with developmental programs can be unraveled through the integration of systematic experimentation with the computational analysis of the generated omics data (Molecular Systems Biology). This Research Topic intends to deepen in the different plant developmental pathways and how the corresponding gene networks evolved from a Molecular Systems Biology perspective. Global approaches for photoperiod, circadian clock and hormone regulated processes; pattern formation, phase-transitions, organ development, etc. will provide new insights on how plant complexity was built during evolution. Understanding the interface and interplay between different regulatory networks will also provide fundamental information on plant biology and focus on those traits that may be important for next-generation agriculture.

Download or read book Gene Regulatory Networks Control Plant Development Cell Identity and Responses to the Environment written by Joel Rodriguez Medina and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As most plants lack the ability to move, they grow and adapt to different environmental conditions. The phenotype of a plant is determined by both its genetic makeup and the environment. Understanding the key molecular players that drive these responses has the potential to guide breeding programs for climate-resilient crops, and advance food security. In this dissertation, I used a systems biology framework to explore how gene regulatory networks underlie plant development and growth in three different contexts: in response to changes in the environment, between root cell types and tissues, and between species. In Chapter I, I link newly identified transcription factors that control nitrogen-associated metabolism with their underlying regulatory network in Arabidopsis thaliana. I further used mutations in key metabolic genes to describe a phenomenon whereby there is extensive transcriptional feedback upon genetic perturbation of metabolism. In Chapter II, I integrate genomic datasets from two different Solanum species. A major finding from analysis of these datasets is the identification of a group of genes with different translational regulation between tomato species upon exposure to elevated CO2. In Chapter III, I describe cases of innovation, conservation, and repurpose of gene function in regulatory circuits controlling cell-type specification in the root of tomato. In Chapter IV I return to gene regulation of nitrogen from a temporal dynamic perspective. I analyze time series expression data to elucidate how the regulation of the nitrogen response changes over time. I propose a subnetwork of genes that are temporally regulated and identify transcription factors that might be important for this mechanism. This work expands our knowledge not only of gene networks at a cell and tissue-specific resolution, but also sheds light on the evolutionary relationships between equivalent cell types in tomato, rice and Arabidopsis

Book excerpt: Plants come in myriads of shapes and colors, and the beauty of plants has fascinated mankind for thousands of years. Long before Mendel discovered the laws of heritab- ity and Darwin developed his theory on evolution, the affection for ornamental plants led people to select alleles that establish novel plant forms. Today, plant developmental biology tries to discover the mechanisms that control the establishment of specialized cell types, tissues, and organs from the fertilized egg during a plant’s life. Although the underlying processes of cell proliferation and differentiation are similar in plants and a- mals, plants are different because their development is usually open, and its outcome is not the faithful repetition of a general plan but is strongly in?uenced by environm- tal conditions. In the last few decades, plant developmental biology has pinpointed a large number of developmental regulators and their interactions and the mechanisms that govern plant development start to emerge. In part, this progress was enabled by the advance of powerful molecular tools for a few model species, most importantly Arabidopsis. This volume of the Methods in Molecular Biology series provides a collection of protocols for many of the common experimental approaches in plant developmental bi- ogy. All chapters are written in the same format as that used in the Methods in Molecular TM Biology series. Each chapter opens with a description of the basic theory behind the method being described.

Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen tremendous progress in unraveling the molecular basis of different plant-microbe interactions. Knowledge has accumulated on the mecha nisms of the microbial infection of plants, which can lead to either disease or resistance. The mechanisms developed by plants to interact with microbes, whether viruses, bacteria, or fungi, involve events that can lead to symbiotic association or to disease or tumor formation. Cell death caused by pathogen infection has been of great interest for many years because of its association with plant resistance. There appear to be two types of plant cell death associated with pathogen infection, a rapid hypersensitive cell death localized at the site of infection during an incompatible interaction between a resistant plant and an avirulent pathogen, and a slow, normosensitive plant cell death that spreads beyond the site of infection during some compatible interactions involving a susceptible plant and a virulent, necrogenic pathogen. Plants possess a number of defense mechanisms against infection, such as (i) production of phytoalexin, (ii) formation of hydrolases, (iii) accumulation of hydroxyproline-rich glycoprotein and lignin deposition, (iv) production of pathogen-related proteins, (v) produc tion of oligosaccharides, jasmonic acid, and various other phenolic substances, and (vi) production of toxin-metabolizing enzymes. Based on these observations, insertion of a single suitable gene in a particular plant has yielded promising results in imparting resistance against specific infection or disease. It appears that a signal received after microbe infection triggers different signal transduction pathways.

Download or read book Transcription Factors for Abiotic Stress Tolerance in Plants written by Shabir Hussain Wani and published by Academic Press. This book was released on 2020-08-05 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transcription Factors for Abiotic Stress Tolerance in Plants highlights advances in the understanding of the regulatory network that impacts plant health and production, providing important insights for improving plant resistance. Plant production worldwide is suffering serious losses due to widespread abiotic stresses increasing as a result of global climate change. Frequently more than one abiotic stress can occur at once, for example extreme temperature and osmotic stress, which increases the complexity of these environmental stresses. Modern genetic engineering technologies are one of the promising tools for development of plants with efficient yields and resilience to abiotic stresses. Hence deciphering the molecular mechanisms and identifying the abiotic stress associated genes that control plant response to abiotic stresses is a vital requirement in developing plants with increased abiotic stress resilience. Addressing the various complexities of transcriptional regulation, this book includes chapters on cross talk and central regulation, regulatory networks, the role of DOF, WRKY and NAC transcription factors, zinc finger proteins, CRISPR/CAS9-based genome editing, C-Repeat (CRT) binding factors (CBFs)/Dehydration responsive element binding factors (DREBs) and factors impacting salt, cold and phosphorous stress levels, as well as transcriptional modulation of genes involved in nanomaterial-plant interactions. Transcription Factors for Abiotic Stress Tolerance in Plants provides a useful reference by unravelling the transcriptional regulatory networks in plants. Researchers and advanced students will find this book a valuable reference for understanding this vital area. Discusses abiotic stress tolerance and adaptive mechanisms based on the findings generated by unlocking the transcriptional regulatory network in plants Presents various kinds of regulatory gene networks identified for drought, salinity, cold and heat stress in plants Highlights urgent climate change issues in plants and their mitigation using modern biotechnological tools including genome editing.

Download or read book Developmental Regulation of Plant Gene Expression written by Don Grierson and published by Springer. This book was released on 2013-03-12 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intricacies of plant growth and development present a fascinating intellectual challenge, and yet our understanding of the subject has increased relatively slowly, despite the application of many different experimental approaches. Now, however, the introduction of molecular methods, coupled with genetic transformation technology, has provided a change in pace, and fundamental advances are occurring rapidly. This volume, the second in our Plant Biotechnology series, shows how we are beginning to understand the molecular basis of plant growth and development, and are thus moving from the descriptive to the predictive stage. The ability, discussed in chapter one, to generate a fivefold change in plant height by overexpression of a single gene for the photoreceptor phytochrome heralds not only a new phase in plant photobiology but also highlights the close relationship between fundamental knowledge and commercial application. Other chapters review progress in our understanding of the molecular basis of hormone action and processes such as tuber development, seed protein synthesis and deposition, fruit ripening, and self-recognition during pollination. The successful uses of antisense genes to alter the colour and pattern of flowers and to change the enzymic composition of ripening fruit are also discussed, together with identification and down regulation of a gene involved in ethylene synthesis by antisense technology. Opportunities are considered for altering the composition and quality of harvested plant organs and for using plants to synthesise novel products.
