#PlantScienceClassics #5: “Jumping Genes”. In 1950 Barbara McClintock published her landmark @PNASNews paper on the #Maize Dissociation (DS) & Activator (Ac) #TransposableElements, revolutionizing the field of #Genetics to hostile opposition from her peers.doi.org/10.1073/pnas.3… 
McClintock started her career & work on #Maize in the 1920s @Cornell, where she immediately made an impact by optimizing chromosome staining methods to characterize the chromosomes of triploid maize in 1929, & then describing the physical basis for chromosomal crossover in 1931.
In 1941 she relocated to @CSHL, where she worked on chromosome breaks in maize. When characterizing a specific break on chromosome 9, she noticed that the break was always associated with a locus she named Dissociation (DS), which could change its position on the chromosome.
