Abstract

▪ Abstract Polygalacturonase-inhibiting proteins (PGIPs) are extracellular plant proteins capable of inhibiting fungal endopolygalacturonases (PGs). Plants have evolved different PGIPs with specific recognition abilities against the many PGs produced by fungi. The genes encoding PGIPs are organized into families, and different members of each family may encode proteins with nearly identical characteristics but different specificities and regulation. PGIPs are typically induced by pathogen infection and stress-related signals. The recognition ability of PGIPs resides in their LRR (leucine-rich repeat) structure, where solvent-exposed residues in the β-strand/β-turn motifs of the LRRs are determinants of specificity. Manipulation of the primary structure of PGIPs is expected to generate more efficient PGIPs with novel recognition specificities to protect crop plants against pathogens.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
