Abstract

Cytochalasin A (CA) blocked the accumulation of phytoalexin and phenylalanine ammonia-lyase (PAL)-protein in pea tissues treated with a fungal elicitor but scarcely affected the PAL-mRNA content. Further analysis showed that CA decreased the PAL-mRNA bound to ribosomes. These results indicate that actin filaments are tightly associated with the translational process of the PAL gene.
