|P.332 top paragraph: "For example, in plants, the largest single gene family in the genome is the protein kinase family (approximately 5% of the protein coding genes), although the specific function for only a few dozen of
these kinases is clearly established. Recent comparative genomics studies have revealed that parasitic nematodes and pathogenic microbes produce plant peptide hormone mimics that target specific plant plasma membrane receptor-like protein kinases, thus
usurping endogenous signaling pathways for their own pathogenic purposes." P.333 top paragraph: "In the best-characterized model plant, Arabidopsis thaliana, there are over 1000 genes encoding protein kinases, out of a total of over 25,000 protein coding genes in the genome. About half of the protein kinases in plants are membrane-bound receptor-like protein kinases which contain a single transmembrane domain with an extracellularly located ectodomain where signaling molecules bind."
