In plants, cysteine protease inhibitors are involved in the regulation of protein turnover and play an important role in resistance against insects and pathogens. AtCYS1 from Arabidopsis thaliana encodes a protein of 102 amino acids that contains the conserved motif of cysteine protease inhibitors belonging to the cystatin superfamily (Gln-Val-Val-Ala-Gly). Recombinant A. thaliana cystatin-1 (AtCYS1) was expressed in Escherichia coli and purified. AtCYS1 inhibits the catalytic activity of… Expand
Two cysteine proteinase inhibitors from Arabidopsis thaliana, AtCYSa and AtCYSb, increasing the salt, drought, oxidation and cold tolerance
TLDR
Northern blot analyses showed that the expressions of AtCYSa andAtCYSb gene in Arabidopsis cells and seedlings were strongly induced by multiple abiotic stresses from high salt, drought, oxidant, and cold, and raised the possibility of using AtCysa and AtcYSb to genetically improve environmental stresses tolerance in plants.

Overexpression of MpCYS4, A Phytocystatin Gene from Malus prunifolia (Willd.) Borkh., Enhances Stomatal Closure to Confer Drought Tolerance in Transgenic Arabidopsis and Apple
TLDR
It is demonstrated that MpCYS4 is involved in ABA-mediated stress signal transduction and confers drought tolerance at least in part by enhancing stomatal closure and up-regulating the transcriptional levels of A BA- and drought-related genes. Expand
Investigating the role of papain-like cysteine protease RD21 in plant-pathogen interactions
TLDR
DCG-04 activity profiling assay showed the suppression of NbRD21 activity and up-regulation of N bRd21 transcript in ATG3 (and ATG6) silenced plants, which implies a connection between RD21, cell death and autophagy, which indicates that some PLCPs are involved in plant-pathogen interactions.

MsCYS1, a developmentally-regulated cystatin from alfalfa.
TLDR
Observations suggest an endogenous protease regulatory role for MsCYS1, possibly associated with the early development of stems and leaves, in alfalfa. Expand
Regulatory Proteolysis in Arabidopsis-Pathogen Interactions
TLDR
This review presents available results on the group of proteases in the model plant Arabidopsis thaliana whose functions in microbial pathogenesis were confirmed and their molecular partners when available. Expand
Involvement of cathepsin B-like genes in disease resistance in Arabidopsis thaliana
TLDR
The roles of cathepsin B genes in the model plant Arabidopsis: a more genetically tractable system are examined and it is shown that NbCathB is localised to the plant apoplast where it is activated upon secretion. Expand
Arabidopsis AtSerpin1, Crystal Structure and in Vivo Interaction with Its Target Protease RESPONSIVE TO DESICCATION-21 (RD21)*
TLDR
The results establish that the major Arabidopsis plant serpin interacts with RESPONSIVE to DESICCATION-21, the first report of the structure and in vivo interaction of a plant serpins with its target protease. Expand
Cloning of a cystatin gene from sugar beet M14 that can enhance plant salt tolerance.
TLDR
Improved understanding of the functions of BvM14-cystatin was improved and the possibility of employing the cystatin in engineering plants for enhanced salt tolerance was highlighted. Expand
Function and Regulation of Xylem Cysteine Protease 1 and Xylem Cysteine Protease 2 in Arabidopsis
TLDR
Functionally, tracheary element-specific expression of XCP2 in Arabidopsis suggested a specialized role for XCP1 in final phases of tracheARY element differentiation, and in addition, Soyacystatin N was an effective in vitro inhibitor of cysteine proteases. Expand
The maize cystatin CC9 interacts with apoplastic cysteine proteases
TLDR
New experimental data on the cysteine protease-cystatin interaction is presented and an in silco analysis of plant cystatins and the identified apoplastic cysteined proteases is provided. Expand

Induction of cysteine and serine proteases during xylogenesis in Zinnia elegans
TLDR
Results indicate that the p48h-17 gene appears to be preferentially associated with xylogenesis, and both the cysteine and serine proteases might be involved in autolysis duringxylogenesis. Expand
The Involvement of Cysteine Proteases and Protease Inhibitor Genes in the Regulation of Programmed Cell Death in Plants
TLDR
It is shown that in soybean cells, PCD-activating oxidative stress induced a set of cysteine proteases, and a new role for proteinase inhibitor genes as modulators of PCD in plants is proposed. Expand

TLDR
chestnut cystatin CsC is active against digestive proteinases from the insect Tribolium castaneum and the mite Dermatophagoides farinae, two important agricultural pests. Expand
Corn kernel cysteine proteinase inhibitor as a novel cystatin superfamily member of plant origin. Molecular cloning and expression studies.
TLDR
Northern blot analysis showed that the amount of mRNA for corn cystatin I reaches a maximum 2 weeks after flowering and then decreases gradually, which is significantly similar to other cystatins in its overall amino acid sequence. Expand
Characterization of a genomic sequence coding for potato multicystatin, an eight-domain cysteine proteinase inhibitor

The pattern of gene expression, as well as the properties of the protein, suggest that PMC has a role in the plant's defense system. Expand
Two Wound-Inducible Soybean Cysteine Proteinase Inhibitors Have Greater Insect Digestive Proteinase Inhibitory Activities than a Constitutive Homolog
TLDR
Results indicate that the wound-inducible soybean CysPIs, N2 and R1, function in host plant defense against insect predation, and that substantial variation in CysPI activity against insect digestive proteinases exists among plant Cys PI proteins. Expand
Jasmonate is essential for insect defense in Arabidopsis
TLDR
Results indicate that the mutant studied will be a good genetic model for testing the practical effectiveness of candidate defense genes and measurements of transcript levels for a gene encoding gluta- thione S-transferase demonstrated that wound induction of this gene is independent ofjasmonatesynthesis.
