Plants have evolved with a complex array of signaling molecules to facilitate their growth and development and their interactions with the environment. A vast number of different peptide molecules form an important but until recently often overlooked component amongst these signaling molecules. Plant peptide signals are involved in regulating meristem growth and organogenesis, modulating plant growth and homeostatic responses. They also have important roles as signals of imminent danger or pathogen attack. This volume focuses on the roles of various peptide signaling molecules in development, defence and homeostasis. As it is likely that further plant peptide signaling molecules remain to be discovered, the last section takes a practical look at methods to identify new peptides and characterise their functions.

In the 90 years since the discovery of the first peptide hormone, insulin, peptides have been recognized as important regulators of physiological functions ranging from metabolism to immune responses in mammals. Peptide Signals in Plants is a new volume in Wiley–Blackwell’s Annual Plant Reviews (APR) widely recognized throughout the world as one of the leading series in plant sciences. Following an introductory chapter, the contents of Peptide Signals in Plants are broadly divided into two sections. The first section covers peptides which regulate interactions with other organisms, including the role of peptides in defense against herbivores and pathogens. The volume’s second section covers peptides that regulate developmental processes, including details of the mechanisms involved in abscission, cell proliferation and stomatal patterning. With chapters written by some of the world’s leading researchers and carefully drawn together and edited by Alisa Huffaker and Gregory Pearce, this is an excellent new volume in Wiley–Blackwell’s Annual Plant Reviews.

The plant root system changes dynamically in response to environmental cues. Plants utilize their root system for uptake of essential mineral nutrients that are heterogeneously distributed in the soil environment. Nutrient-dependent modulation of root system architecture (RSA) traits such as primary root growth, lateral root emergence, and the angles at which these roots grow allows for optimization of nutrient acquisition. Among signaling pathways by which plants may sense the availability of nutrients from the environment, small signaling peptide (SSP) pathways play important roles in optimizing root functions. These SSP pathways may further regulate molecular processes underlying RSA, such as the biosynthesis and transport of the major plant growth hormone, auxin. Characterization of these nutrient-responsive SSP pathways is thus of great importance and critical for understanding plant development in nutrient-poor environments. For my dissertation, I have identified and characterized a nitrogen (N)-responsive SSP pathway modulating root gravitropic response and lateral root development. Co-regulation of these RSA components by this module is proposed to prevent root outgrowth into N-poor regions and drive deeper root growth towards mobile nitrate (NO3-) resources stratified deeper in the soil profile. First, I show that a signaling pathway involving the CLAVATA3/EMBRYO SURROUNDING REGION-RELATED (CLE) family of peptides and the CLAVATA1 (CLV1) receptor kinase, which is involved in N-dependent repression of lateral root emergence, also enhances root gravitropic response under N-limited conditions. Transcriptomic profiling of a clv1 mutant and CLE3 overexpressing lines identified Arabidopsis thaliana CENTRORADIALIS (ATC), a mobile protein previously characterized for its role in flowering regulation, as a downstream target of CLE-CLV1 signaling. Loss of ATC function significantly weakens root gravitropic response and has a moderate impact on lateral root emergence under low NO3- availability. ATC promoter activity and protein localization are also detected throughout the phloem and in the root columella cells, which are major centers for gravity sensing. Second, I demonstrate the relevance of ATC function on the molecular processes underlying root gravitropic response. While mutation in ATC does not impact gravity sensing via amyloplast sedimentation, it does inhibit the asymmetric transport of auxin needed for gravitropic bending. I determine that this occurs via the significant reduction of the PIN3 auxin efflux transporter in the vasculature and root tip of atc mutant lines. Lastly, I examine how the known roles of ATC in floral development could be implicated in root developmental processes. ATC binds to phosphatidic acid and phosphatidylserine, which is contrary to the binding capacity of its homolog FLOWERING LOCUS T (FT) to phosphatidylcholine and may contribute to its activity in N-limited environments. I also investigate the interaction of ATC and the transcription factor FD in the transcriptional regulation of PIN3. Although FD appears to have an impact on root gravitropic response, FD inhibits the expression of PIN3, suggesting potentially complex control of this gene via floral regulatory components. Taken together, the results presented in this dissertation contribute greatly to our understanding of how plant root architecture alters in response to N. These results can be further utilized in plant engineering strategies to regulate root growth in nutrient-limited soils.

An understanding of the mechanisms by which plants perceive environmental cues, both physical and chemical, and transduce the signals that influence specific expression of genes, is an area of intensive scientific research. With the completion of the genome sequence of Arabidopsis it is understood now that a larger number of genes encode for proteins involved in signalling cascades and transcription factors. In this volume, different chapters deal with plant receptors, second messengers like calcium ions, phosphoinositides, salicylic acid and nitrous oxide, calcium binding proteins and kinases. In addition to dealing with the response of plants to light, hormones, pathogens, heat, etc. on cellular activity, work currently going on in apoptosis, cell division, and plastid gene expression is also covered in this book.

Plant Hormones: Biosynthesis and Mechanisms of Action is based on research funded by the Chinese government’s National Natural Science Foundation of China (NSFC). This book brings a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions. With growing understanding of hormone biology comes new outlooks on how mankind values and utilizes the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner. This book is a comprehensive description of all major plant hormones: how they are synthesized and catabolized; how they are perceived by plant cells; how they trigger signal transduction; how they regulate gene expression; how they regulate plant growth, development and defense responses; and how we measure plant hormones. This is an exciting time for researchers interested in plant hormones. Plants rely on a diverse set of small molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone auxin, hormones have always been the frontiers of plant biology. Although the physiological functions of most plant hormones have been studied for decades, the last 15 to 20 years have seen a dramatic progress in our understanding of the molecular mechanisms of hormone actions. The publication of the whole genome sequences of the model systems of Arabidopsis and rice, together with the advent of multidisciplinary approaches has opened the door to successful experimentation on plant hormone actions. Offers a comprehensive description of all major plant hormones including the recently discovered strigolactones and several peptide hormones Contains a chapter describing how plant hormones regulate stem cells Offers a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions Discusses the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner

Long and short-range signaling systems in plants have previously been attributed to plant hormones. In animals, peptide signaling is the major mechanism in cell-cell communication, although little is known about this system in plants. The Cysteine-Rich Peptides (CRP) forms an emerging class of potential signaling ligands, which have been implicated in several signaling events during plant reproduction. However, little is known about their role during seed development. Recent studies have identified a significant number of CRP encoding genes in Arabidopsis thaliana of unknown function. A sub-class of MEG1-related CRPs were identified in seeds. These peptides contain 8 and 12 conserved cysteine residues, and undergo a rapid turnover by protein ubiquitination. A subgroup of these genes (AtMEG13/14/15) are expressed in the central cell and in the embryo-surrounding region of the endosperm during early seed development. Functional analysis of these peptides revealed seed abnormalities associated with defects in suspensor development and embryo patterning. Genetic analyses revealed that these genes are required before and after fertilization for correct embryo development. In addition, they also act in a parallel pathway to the SHORT SUSPENSOR to regulate early embryo development through the YODA mitogen-activated protein kinase signaling cascade. My findings highlight the novel existence of extra-embryonic factors that regulate early embryo development in plants.

Sequencing projects have revealed the presence of at least several hundred receptor kinases in a typical plant genome. Receptor kinases are therefore the largest family of primary signal transducers in plants, and their abundance suggests an immense signaling network that we have only just begun to uncover. Recent research findings indicate that individual receptor kinases fulfill important roles in growth and development, in the recognition of pathogens and symbionts or, in a few examples, in both growth and defense. This volume will focus on the roles of receptor kinases, their signaling pathways, and the ways in which these important signaling proteins are regulated.
