Structure-function and application of plant lectins in disease …
Moreover, some small lectins also directly penetrate the fungal cell wall and reach cell membrane where they block the enzyme activity by binding to active sites and therefore influence cell wall morphogenesis.
Plant Lectins and Lectin Receptor-Like Kinases: How Do They
May 31, 2017 · Lectins are fundamental to plant life and have important roles in cell-to-cell communication; development and defence strategies. At the cell surface; lectins are present both as soluble proteins (LecPs) and as chimeric proteins: lectins are then the extracellular domains of receptor-like kinases (L ….
Monitoring the Outside: Cell Wall-Sensing Mechanisms
May 27, 2010 · Lectins have been identified as proteins that bind carbohydrates, suggesting that, in the context of LecRKs, the lectin domain establishes a direct link to cell wall polysaccharides (André et al., 2005; Bouwmeester and Govers, 2009). However, at least some LecRKs undergo protein-protein interactions.
Plant lectins and their many roles: Carbohydrate-binding and beyond
Nov 1, 2021 · Lectin S-domain receptor kinase 29 (SD1-29) recognizes lipopolysaccharide (LPS) present in the cell walls of Pseudomonas and Xanthomonas species, and triggers innate immunity. Loss-of-function mutants are hyper-susceptible to P. syringae ( Ranf et al., 2015 ).
Plant lectins: Classical molecules with emerging roles in stress ...
Jul 31, 2023 · Further, in response to low temperature, the activity of a cell wall-bound lectin was found to increase in wheat that conferred freeze tolerance in a calcium-dependent manner. Cell wall-bound lectins act as receptors that perceive the stress stimuli and transduce these signals to different cellular compartments in response to stress [ 38 , 39 ].
C-type lectins in immunity and homeostasis - Nature
Mar 26, 2018 · C-type lectins are well known for their ability to recognize the carbohydrate-rich cell walls of fungi, and they are now accepted to have a central role in immunity to most fungal pathogens.
Plant Lectins and Lectin Receptor-Like Kinases: How Do They …
May 31, 2017 · The potential ligands for LecRK-I.9, i.e., ATP or/and RGD-containing peptides, are far from what could be expected for a lectin domain facing the cell wall polysaccharides and the N-and O-glycans of glycoproteins.
The fungal-specific β-glucan-binding lectin FGB1 alters cell-wall ...
Oct 27, 2016 · By cytological and biochemical approaches, we show that FGB1 is a secreted lectin that binds β-glucan, alters fungal cell wall composition and suppresses glucan triggered reactive oxygen...
The plasma membrane – cell wall nexus in plant cells: focus on …
Dec 15, 2023 · open access. Across all kingdoms of life, cells secrete an extracellular polymer mesh that in turn feeds back onto them. This entails physical connections between the plasma membrane and the polymer mesh.
Lectin Receptor Kinases Participate in Protein-Protein Interactions …
Dec 16, 2005 · In this study, we show that the lectin receptor kinase (LecRK) encoded by At5g60300 is a potential interacting molecule involved in plasma membrane-cell wall adhesions. The possibility that RGD-containing proteins act as ligands for LecRK in plants is discussed.
