The phrase "mutant lines" refers to genetic variations or alterations in living organisms that cause them to differ from their normal or original form. Full definition
Dubcovsky and his colleagues chemically induced random genetic mutations in thousands of wheat seeds and began developing and characterizing their collection of wheat mutant lines more than five years ago. (sciencedaily.com)
And the genetic makeup of the flies also mattered, because lifelong antibiotic treatment caused one normally long - lived mutant line to die at the same age as normal flies given antibiotics — in other words, its life span was extended only in the presence of bacteria, the researchers report in this week's issue of Proceedings of the National Academy of Sciences.
