    Abstract

    A barley (Hordeum vulgare L.) cDNA, PM19, encoding a putative plasma membrane protein was isolated through differential screening of a dormant wild oat embryo library. PM19 is expressed in barley embryos from mid-embryogenesis up to maturity. PM19 mRNA levels decline upon germination, whereas dormant embryos retained high levels of message for up to 72 h of imbibition. PM19 mRNA levels also remained high or were reinduced in non-dormant embryos by treatments that prevented germination (250 mm NaCl, 10% sorbitol, or 50 µm ABA). The PM19 protein sequence is highly conserved in monocotyledonous and dicotyledonous plants.
