Gai3 Gibberellic Acid Response (insensitivity) GAI3 4B,4BS i:See,v:Minister Dwarf,v:Selection D6899,v:Tom Thumb,v:Tom Thumb Der.
Comment:
In wheats with Gai3, the aleurone layer fails to respond to applied GA {405}.
Two studies involving crosses between Tom Thumb derivatives and tall parents suggested that gibberellic acid insensitivity and reduced height were controlled by one gene, i.e., Gai3 {359,413}. In a third study involving a Tom Thumb derivative, recombinants were isolated, indicating separate but linked genes, i.e., Gai3 and Rht-B1c {565,567}. Further evidence was obtained for linkage between genes for gibberellic acid insensitivity and Norin 10 genes for reduced height in hexaploid {568} and durum {720} wheats. Hu & Konzak {567} reported 27% recombination between Gai1 and Rht-B1b and 10% recombination between Gai2 and Rht-D1b in hexaploid wheats involving Norin 10 and Suwon 92 derivatives. In durum derived from crosses involving Norin 10, 15% recombination was obtained between one of the genes for reduced height and gibberellic acid insensitivity {1246,1247}. Gale & Law {403} considered Gai1 and Rht-B1b, Gai2 and Rht-D1b, Gai3/ and Rht-B1c to be pleiotropic genes.
