Abstract
Improved barstar DNAs, such as synthetic barstar DNAs, produce high amounts of barstar protein in eucaryotic cells, particularly in plant cells, and especially in stamen cells such as tapetum cells. Synthetic barstar DNAs have less than 40% A and T nucleotides. Other improved barstar DNAs encode improved barstar proteins which have an N-terminus which starts with Met-Xaa wherein Xaa is Alanine, Valine, Glycine, Aspartic acid or Glutamic acid. Plan cells and plants contain the improved barstar DNAs and/or express the improved barstar protein.
