Table 2 Effect of light intensity and cell concentration on false positive appearance

From: TETX: a novel nuclear selection marker for Chlamydomonas reinhardtii transformation

Cells/plate Light intensity (μmoles m −2s −1 )

  1. We measured the appearance of false positives on tetX transformed C. reinhardtii plates when grown at different cell concentrations and light intensities: (−) indicates no false positives, (+) indicates presence of false positives.
