“…Plants have developed intricate signaling systems that employ secreted peptides and membrane bound receptor kinases for short- and long-range communication (Stahl and Simon, 2012; Yamada and Sawa, 2013). Peptides belonging to the CLV3/EMBRYO SURROUNDING REGION (CLE) family act as signals in several of these pathways including root development and nodule formation (Stahl and Simon, 2012; Yamada and Sawa, 2013).…”

Several studies have shown that plant hormones play important roles during legume–rhizobia symbiosis. For instance, auxins induce the formation of nodule-like structures (NLSs) on legume roots in the absence of rhizobia. Furthermore, these NLS can be colonized by nitrogen-fixing bacteria, which favor nitrogen fixation compared to regular roots and subsequently increase plant yield. Interestingly, auxin also induces similar NLS in cereal roots. While several genetic studies have identified plant genes controlling NLS formation in legumes, no studies have investigated the genes involved in NLS formation in cereals. In this study, first we established an efficient experimental system to induce NLS in rice roots, using auxin, 2,4-D, consistently at a high frequency (>90%). We were able to induce NLS at a high frequency in Medicago truncatula under similar conditions. NLS were characterized by a broad base, a diffuse meristem, and increased cell differentiation in the vasculature. Interestingly, NLS formation appeared very similar in both rice and Medicago, suggesting a similar developmental program. We show that NLS formation in both rice and Medicago occurs downstream of the common symbiotic pathway. Furthermore, NLS formation occurs downstream of cytokinin-induced step(s). We performed a comprehensive RNA sequencing experiment to identify genes differentially expressed during NLS formation in rice and identified several promising genes for control of NLS based on their biological and molecular functions. We validated the expression patterns of several genes using reverse transcription polymerase chain reaction and show varied expression patterns of these genes during different stages of NLS formation. Finally, we show that NLS induced on rice roots under these conditions can be colonized by nitrogen-fixing bacteria, Azorhizobium caulinodans.

“…Peptides belonging to the CLV3/EMBRYO SURROUNDING REGION (CLE) family act as signals in several of these pathways including root development and nodule formation (Stahl and Simon, 2012; Yamada and Sawa, 2013). In rice, FON2, closely related to CLV3, regulates meristem size and requires FON1, an ortholog of CLV1 (Suzaki et al, 2006).…”

“…This dual function, therefore, forms the basis of a homeostatic mechanism to prevent the unregulated division of pluripotent cells. More details on the role of peptide -receptor kinase signalling in root development will be highlighted further on in this issue by Stahl & Simon [94].…”

Roots are important to plants for a wide variety of processes, including nutrient and water uptake, anchoring and mechanical support, storage functions, and as the major interface between the plant and various biotic and abiotic factors in the soil environment. Understanding the development and architecture of roots holds potential for the exploitation and manipulation of root characteristics to both increase food plant yield and optimize agricultural land use. This theme issue highlights the importance of investigating specific aspects of root architecture in both the model plant Arabidopsis thaliana and (cereal) crops, presents novel insights into elements that are currently hardly addressed and provides new tools and technologies to study various aspects of root system architecture. This introduction gives a broad overview of the importance of the root system and provides a snapshot of the molecular control mechanisms associated with root branching and responses to the environment in A. thaliana and cereal crops.

“…Signaling peptides have been associated to diverse developmental processes in plants, such as apical meristem maintenance (CLAVATA3 (CLV3), GLV/RGF/CLEL), defense (systemins), floral organ abscission (IDA), and stomatal patterning (EPF), among others [4,38,[43][44][45][46]. To highlight the diverse roles of signaling peptides in various developmental processes, some examples of the function of the signaling peptide families are outlined below.…”

“…Receptors are activated upon binding of their ligand, often through autophosphorylation. Activated receptors will, in turn, phosphorylate downstream targets, which might result in a direct response and/or a phosphorylation cascade, including mitogen-activated protein (MAP)-kinases, and eventually lead to transcriptional regulation of specific genes [12,13,36,38].…”

In multicellular organisms, growth and development need to be precisely coordinated and are strongly relying on positional information. Positional control is achieved through exchanges of molecular messages between cells and tissues by means of cell-to-cell communication mechanisms. Especially in plants, accurate and well-controlled cell-to-cell communication networks are essential because of the complete absence of cell mobility and the presence of rigid cell walls. For many years, phytohormones were thought to be the main messengers exchanged between cells. Nevertheless, identification of systemin as the first plant signaling peptide in tomato hinted that peptide hormones were acting in plants as they were in animals. During the last decade, our knowledge of plant signaling peptides has progressed considerably and a number of signaling peptide families have been discovered and partially characterized. Here, we provide an overview of the current knowledge in signaling peptides in the model species Arabidopsis thaliana and discuss their proposed functions during plant growth and development.
