title: JIP60, a methyl jasmonate-induced ribosome-inactivating protein involved in plant stress reactions.
abstract: Plant tissues treated with the naturally occurring cyclopentanone compound methyl jasmonate or exposed to stress causing in planta jasmonate accumulation express distinctive proteins and, concomitantly, reduce the synthesis of most preexisting proteins. One of the recently identified jasmonate-induced proteins, designated JIP60, in barley is a ribosome-inactivating protein that cleaves polysomes of both animal and plant origin into their ribosomal subunits. By attacking foreign and self ribosomes, respectively, JIP60 appears to be both a defense protein and a potent regulator of protein synthesis in stressed plant tissues.
