Grasses contain a number of genes encoding both α- and β-expansins. These cell wall proteins are predicted to play a role in cell wall modifications, particularly during tissue elongation. We report here on the characterisation of five α- and three vegetative β-expansins expressed in the leaf elongation zone (LEZ) of the forage grass, Festuca pratensis Huds. The expression of the predominant α-expansin (FpExp2) was localised to the vascular tissue, as was the β-expansin FpExpB3. Expression of… CONTINUE READING
