Cell Signaling in Plants

Cell Signaling in Plants

Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Defenses Against Pathogens and Herbivores

Defenses Against Pathogens and Herbivores

Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Transgenic Plants

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Photoreceptors and Plant Responses to Light

Photoreceptors and Plant Responses to Light

Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Diversity of Antigen Receptors

Diversity of Antigen Receptors

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

Transducer Mechanism: Enzyme-Linked Receptors

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Background:

Crop plants face significant threats from pathogen infestations, impacting global food security.
Plants possess innate immunity, utilizing Pattern Recognition Receptors (PRRs) to identify pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs).
Pattern-Triggered Immunity (PTI) is a key plant defense mechanism activated by PRRs, involving complex signaling pathways and receptor complexes.

Purpose of the Study:

To provide an updated overview of PRRs involved in plant disease resistance.
To elucidate the mechanisms of ligand recognition and active receptor complex formation by PRRs.
To present diverse applications of PRRs and PTI in managing plant diseases and enhancing crop resilience.

Main Methods:

Review of current literature on PRRs, PAMPs, DAMPs, and PTI signaling pathways.
Analysis of PRR structural domains (e.g., LRR, lectin) and their roles in ligand binding.
Exploration of genetic modification strategies involving PRR transfer for broad-spectrum resistance.

Main Results:

PRRs, with diverse ectodomains, effectively recognize MAMPs and DAMPs, triggering PTI responses like ROS production and defense gene induction.
Nucleotide-binding Oligomerization Domain, Leucine-rich Repeat proteins (NLRs) are integral to intracellular immunity, responding potently to pathogen effectors.
Understanding PRR signaling pathways identifies potential targets for developing genetically modified plants with enhanced disease resistance.

Conclusions:

Enhanced knowledge of PRRs and PTI mechanisms provides a foundation for innovative plant protection strategies.
Transferring PRRs across species can confer broad-spectrum resistance, contributing to sustainable agriculture and food security.
PRRs and PTI represent promising targets for developing novel approaches to disease resistance management in crops.
