Germplasm Phenotype:

• gpat4/gpat8  — This double knock-out mutant has a 60-70% overall decrease in cutin monomer content in leaf and stem. The plant grew slowly. The water loss rate for rosettes was 4-fold greater than wild type. The mutant has an increased sensitivity to fungal pathogen. Defects in stomata structure.
