“…CYSTEINE‐RICH RECEPTOR‐LIKE KINASE 28 (CRK28) was shown to regulates the growth and development of the root and shoot system, and to fine‐tune abscisic acid signaling in germination and early root growth (Pelagio‐Flores et al, 2020). In rice, several RLKs with distinct extracellular domains have been reported recently.…”

“…MAMPs/PAMPs correspond to essential conserved regions of pathogen or microbial components. Likewise, PTI can also be activated upon the detection of DAMAGE-ASSOCIATED MOLECULAR PATTERNS (DAMPs), which are molecules secreted by the plants as a result of exposure to biotic and abiotic stresses ( Figure 2A) (Gust et al, 2017;Tang et al, 2017;Ortiz-Morea and Reyes-Bermudez, 2019). Activation of PTI leads to an increase of intracellular calcium, activation of MITOGEN-ACTIVATED PROTEIN KINASE (MAPK), a burst of reactive oxygen species (ROS), activation of CALCIUM-DEPENDENT PROTEIN KINASEs (CDPKs), massive transcriptional reprogramming, stomata closure, callose deposition, and so forth ( Figure 2A) (Wu et al, 2014;Couto and Zipfel, 2016;Yu et al, 2017;Wang et al, 2020aWang et al, , 2020bWang et al, , 2020c.…”

As sessile organisms, plants are exposed to pathogen invasions and environmental fluctuations. To overcome the challenges of their surroundings, plants acquire the potential to sense endogenous and exogenous cues, resulting in their adaptability. Hence, plants have evolved a large collection of plasma membrane-resident receptors, including RECEPTOR-LIKE KINASEs (RLKs) and RECEPTOR-LIKE PROTEINs (RLPs) to perceive those signals and regulate plant growth, development, and immunity. The ability of RLKs and RLPs to recognize distinct ligands relies on diverse categories of extracellular domains evolved. Co-regulatory receptors are often required to associate with RLKs and RLPs to facilitate cellular signal transduction. RECEPTOR-LIKE CYTOPLASMIC KINASEs (RLCKs) also associate with the complex, bifurcating the signal to key signaling hubs, such as MITOGEN-ACTIVATED PROTEIN KINASE (MAPK) cascades, to regulate diverse biological processes. Here, we discuss recent knowledge advances in understanding the roles of RLKs and RLPs in plant growth, development, and immunity, and their connection with co-regulatory receptors, leading to activation of diverse intracellular signaling pathways.

“…Flagella are motile organs of many bacteria, and fragments of the flagellin protein are shed during bacterial invasion. Flg22 is a 22-amino acid moiety of flagellin that is capable of provoking an immune response from plants [9]. Flagellin (and flg22) is the ligand for FLAGELLIN-SENSING 2 (FLS2), a receptor in plant cell membranes.…”

Plant Elicitor Peptide (Pep) Signaling and Pathogen Defense in Tomato

Endogenous signaling compounds are intermediaries in signaling pathways that plants use to respond to the perception of harmful and beneficial organisms. The plant elicitor peptides (Peps) of plants are important endogenous signaling molecules that induce elements of defense responses such as hormone production, increased expression of defensive genes, the activation of phosphorelays, and the induction of cell secondary messenger synthesis. The processes by which Peps confer resistance to pathogenic microorganisms have been extensively studied in Arabidopsis but are less known in crop plants. Tomato and many other solanaceous plants have an endogenous signaling polypeptide, systemin, that is involved in the defense against herbivorous insects and necrotrophic pathogens. This paper explores the similarity of the effects and chemical properties of Pep and systemin in tomato. Additionally, the relationship of the Pep receptor and systemin receptors is explored, and the identification of a second tomato Pep receptor in the literature is called into question. We suggest future directions for research on Pep signaling in solanaceous crops during interactions with microbes.

“…1). In addition, upon pathogen infection and cell injury, damage-associated molecular patterns (DAMPs) are released into the extracellular space, where they can then diffuse to neighbouring cells and amplify the PTI response (Yamaguchi and Huffaker, 2011;Hou et al, 2014;Yu et al, 2017;Ortiz-Morea and Reyes-Bermudez, 2019) (Fig. 1).…”

It takes two to tango – molecular links between plant immunity and brassinosteroid signalling

In response to the invasion of microorganisms, plants actively balance their resources for growth and defence, thus ensuring their survival. The regulatory mechanisms underlying plant immunity and growth operate through complex networks, in which the brassinosteroid phytohormone is one of the central players. In the past decades, a growing number of studies have revealed a multi-layered crosstalk between brassinosteroid-mediated growth and plant immunity. In this Review, by means of the tango metaphor, we immerse ourselves into the intimate relationship between brassinosteroid and plant immune signalling pathways that is tailored by the lifestyle of the pathogen and modulated by other phytohormones. The plasma membrane is the unique stage where brassinosteroid and immune signals are dynamically integrated and where compartmentalization into nanodomains that host distinct protein consortia is crucial for the dance. Shared downstream signalling components and transcription factors relay the tango play to the nucleus to activate the plant defence response and other phytohormonal signalling pathways for the finale. Understanding how brassinosteroid and immune signalling pathways are integrated in plants will help develop strategies to minimize the growth–defence trade-off, a key challenge for crop improvement.
