Germplasm Phenotype:

• mgd2 mgd3  — No visible or biochemically determinable mutant phenotype observed under nutrient-sufficient conditions.
• mgd2 mgd3  — Under Pi starved conditions, reduced DGDG content is observed, the proportion of phosphatidylethanolamine and phosphatidylcholine increased approximately two-fold in shoot and large differences in fatty acid compositions of galactolipids are seen in shoots and particularly roots. Under these conditions, the fresh weight of shoots and roots was reduced.
• mgd2-1  — No visible or biochemically determinable mutant phenotype observed under nutrient-sufficient conditions.
