(a) The number of successfully engineered thraustochytrid strains by one or more methods (electroporation [20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52], biolistic transformation [5,27,53,54,55], and others [56,57,58,59]) (Tables S1 and S2). The doughnut pie charts indicate the proportion of different genera. Four strains have been transformed by more than one method: a
A. limacinum mh018 and T. aureum ATCC 34304; b
Schizochytrium sp. S31; c
Schizochytrium sp. TIO1101; (b) The number of successfully transformed thraustochytrid strains and the methods applied in recent years. Any strain–method combinations are counted only once, even if they are used in several publications.
