Percentage of plants showing the pollen lethality phenotype in transgenic Arabidopsis populations

Pollen lethality phenotype is defined as the production of 20% to 50% aborted pollen per anther. Percentage of plants exhibiting this phenotype in each transgenic population was determined by three independent scorings, each comprising 100 transgenic T1 plants. Information on vectors is available upon request. Values are depicted as means ± sd.
