Starch mutants:

We have been carrying out a selection for starch mutants in Lotus japonicus using the iodine-staining properties of the leaves. Mutants have been isolated that cannot make starch (in plastidial phosphoglucomutase, phosphoglucoisomerase, and ADPG pyrophosphorylase) and cannot break it down following the dark period (in glucan, water dikinases). We are using these to study nodule function and agronomically important traits.
