Proc Natl Acad Sci USA 1998, 95:4766-4771. Interactions between different plant hormones are important for plant development. Cytokinin is known to induce ethylene. cin5 is one of the mutants isolated by Kieber's group [7••], and does not respond to low levels cytokinin by producing ethylene. The cin5 mutation disrupts the ACS5 gene that encodes one of the 1-aminocyclopropane-1-carboxylate synthases.

Genetics 1998, 149:417-427. Large scale screening was carried out to identify mutants in which ethylene biosynthesis is not induced by low levels of cytokinin. The identified mutations represent five genetic loci, and disrupted different steps leading from cytokinin perception to ethylene production.
