TL;DR: The rice Xa21 gene, which confers resistance to Xanthomonas oryzae pv. race 6, was isolated by positional cloning and the sequence of the predicted protein, which carries both a leucine-rich repeat motif and a serine-threonine kinase-like domain, suggests a role in cell surface recognition of a pathogen ligand and subsequent activation of an intracellular defense response.

TL;DR: A model for amplification and diversification of the Xa21 gene family is presented and two distinct classes of genes are revealed, including a receptor kinase-like open reading frame and truncated open reading frames of the predicted receptor Kinase.

TL;DR: P pig folylpoly-gamma-carboxypeptidase, rat N-acetylated alpha-linked acidic dipeptidases, and human prostate-specific membrane antigen appear to represent varied expressions of the same gene in different species and tissues.

TL;DR: Host-specific toxins from Helminthosporium victoriae and Periconia circinata and PC caused gradual decreases in the negative electropotentials of single cells of susceptible but not of resistant plants, but do affect passive efflux of ions, or electrically neutral ion exchange systems, across the plasma membrane.

TL;DR: A high molecular weight (6 S) plant DNA polymerase from axenic Vinca rosea tissue culture cells has been purified 2200-fold and characterized, suggesting no antigenic relationships between the mammalian and plant enzymes.
