- 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.
