Summary Plants rely on an innate immune system to defend against pathogens through various molecular responses. In addition to classical damage-and pathogen-associated molecular patterns (DAMPs and PAMPs), plants produce endogenous signaling peptides termed phytocytokines that amplify and regulate immune responses following stress. …

Phytocytokines are endogenous peptides that modulate plant immunity outcomes, yet how their maturation and spatial deployment are controlled remains unclear. Here we show that the maize phytocytokine precursor PROZIP1 is controlled by a spatially separated, 2-stage proteolytic pathway that mechanistically uncouples signal …

Macrophomina phaseolina (Tassi) Goid. is a fungal pathogen that causes charcoal rot (CR) disease in various legumes, including soybean. To date, no reliable resistance gene sources have been identified in soybean or other legumes to combat M. phaseolina. The apoplast is a …

Plant signaling peptides, also known as phytocytokines, play a crucial role in cell-to-cell communication during plant development and immunity. The detection of small peptides in plant tissues is challenging and often relies on time-consuming and cost-intensive approaches. Here, we present an ELISA-based …

Phytocytokines play a critical role in the fine tuning of plant immunity and development. The final bioactive peptide form can vary from 1-5 kDa and is usually expressed in low amounts, making them difficult to detect with conventional methods. Here, we present …

Abstract Plant signaling peptides, also known as phytocytokines, are involved in a number of signaling mechanisms, including cell-to-cell communication during plant development and immunity. The detection of small peptides in plant tissues is challenging and often relies on time-consuming and cost-intensive approaches. …

Regulated cell death (RCD) is crucial for plant development, as well as in decision-making in plant-microbe interactions. Previous studies revealed components of the molecular network controlling RCD, including different proteases. However, the identity, the proteolytic network as well as molecular components involved …

Plant pathogens secrete effectors, which target host proteins to facilitate infection. The Ustilago maydis effector UmSee1 is required for tumor formation in the leaf during infection of maize. UmSee1 interacts with maize SGT1 (suppressor of G2 allele of skp1) and blocks its …

Phytocytokines are signaling peptides that alert plant cells of danger. However, the downstream responses triggered by phytocytokines and their effect on plant survival are still largely unknown. Here, we have identified three biologically active maize orthologues of phytocytokines previously described in other …

Abstract Phytocytokines are signalling peptides that activate immune responses and alarm bystander cells of danger. The pathways of phytocytokine perception and activation are thought to be shared between exogenous danger signals such as microbe-associated molecular patterns (MAMPs) and endogenous, passively released, damage-associated …
