Electroporation of strains CC3395 and CC425, cell wall-less mutants devoid of argininosuccinate lyase (encoded by ARG7 ), in the presence of the plasmid pJD67 (which contains ARG7 ) was used to optimize conditions for the introduction of exogenous DNA. In these plants, starch granule size distribution is bimodal6–8; large disk-like granules (called A-type granules with an average diameter of about 25 µm in wheat) and smaller but spherical granules (called B-type granules with a diameter under 10 µm in wheat) accumulate in the endosperm9. If the conditions around them are less good, C. reinhardtii can reproduce sexually. C. reinhardtii 137c is a eukaryote with a large genome size of 121 Mb, and a versatile and proven model organism.
