- Plant PIs fulfill two major functions: (i) they prohibit proteolytic degradation of storage proteins in seeds or kernels to enable the controlled mobilization of nutrients in the form of amino acids or small peptides; and (ii) they protect the plant against herbivores, leading to starvation of these pests by inhibition of digestive enzymes or hemolysis of the gastrointestinal tract 5, 6.

Apr 18, 2023 · Upon exposure to drought, plants undergo complex signal transduction events with concomitant changes in the expression of genes, proteins and metabolites. For example, proteomics studies continue to identify multitudes of drought-responsive proteins with diverse roles in drought adaptation.
Dec 14, 2017 · Plants have evolved an intricate regulatory network of proteases and corresponding protease inhibitors (PI), which operate in various biological pathways and serve diverse spatiotemporal functions during the sedentary life of a plant.

PMCID: PMC6471620 PMID: 30884891. Abstract. The serine protease inhibitors (SPIs) are widely distributed in living organisms like bacteria, fungi, plants, and humans. The main function of SPIs as protease enzymes is to regulate the proteolytic activity. In plants, most of the studies of SPIs have been focused on their physiological role.
Jan 1, 2024 · Plant protease inhibitors (PPIs) are a family of small protein/peptide/amino acid derivatives that are involved in important biological processes of plants including growth, development, and defense against pests and pathogens (Polya, 2003; Van Der Hoorn, 2008).
Feb 8, 2023 · Here, we review the known mechanisms for the activation of plant proteases, including post-translational modifications, together with the effects of proteinaceous inhibitors.
Protease inhibitors from plants are proteinaceous molecules which form complex with proteases and inhibit their activity. Plants utilize these inhibitors to regulate different physiological processes as well as to protect themselves against insect pests or pathogens.
