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.

This book summarizes the latest studies on plant reproduction and multiple aspects of signaling in reproductive development. It also presents the most advanced processes in CrRLK1L receptor and RALF peptide studies during plant development. Focusing on signaling in pollen tube integrity and sperm release regulation, it provides significant insights into the BUPS-ANX receptor complex and the corresponding ligands RALF4/19 to promote pollen tube growth with proper cell integrity. It also proposes a working model of female tissue-derived RALF34 competing with RALF4/19 from the BUPS-ANX to trigger pollen tube rupture and sperm release. Offering a detailed overview of the spatiotemporal regulation mechanism underlying the control of pollen tube integrity and sperm release, the book fills a major gap in our understanding of plant reproductive processes, and as such is a valuable resource for those working in the area of plant signaling.

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.

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.

Plant signalling has emerged as an integrated field which has become indispensable in recent times to study any biological process. Over the last decade, an enormous amount of information has been generated in this field and the advances in information technology gave birth to bioinformatics which has helped greatly in managing the galaxy of information. It is now possible to view the different information’s in a systems biology approach which has unravelled the association/ new processes and thus helped us enormously in understanding of the biological processes. The present book is an attempt at understanding the plant signalling processes with different perspectives. Even though the plants are sessile but there exists a tremendous interconnected network of perception at morphological, physiological and molecular levels. The impact of the surrounding environment in terms of abiotic and biotic stresses is significant in terms of its survival, adaptation and productivity for the human welfare. The plants possess a wide array of processes at the organ, tissue and cellular levels which are governed by a plethora of molecules. The molecules govern individual processes and these exists a cross talk between them to form a complex network of processes. The book tries to envision how different processes are operating at different points in the life cycle of the plant.
