Germplasm Phenotype:

• CS25269  — No adult visible phenotype under long-day or short-day conditions; cytokinin sensitivity similar to wild type in seedling root elongation and seedling lateral root formation; increased sensitivity to red light.
• CS25275  — No adult visible phenotype; increased cytokinin sensitivity of root elongation but intermediate between the wild type and the arr5,6,8,9 or arr3,4,8,9 quadruple mutants; intermediate cytokinin sensitivity between the wild type and arr3,4,5,6, arr5,6,8,9 and arr3,4,8,9 quadruple mutants in seedling lateral root formation (develop slightly fewer lateral roots in the absence of exogenous cytokinin).
• CS25277  — No adult visible phenotype; root elongation responses intermediate between arr3,4,5,6,8,9 and the wild type; but significantly more sensitive than arr8,9; intermediate cytokinin sensitivity in seedling lateral root formation, between the wild type and the arr3,4,5,6,8,9 hextuple mutant, with the sensitivity of arr3,4,8,9 closest to arr3,4,5,6,8,9; intermediate cytokinin sensitivity in seedling lateral root formation, between the wild type and the arr3,4,5,6,8,9 hextuple mutant, with the sensitivity of arr3,4,8,9 closest to arr3,4,5,6,8,9.
• CS25278  — No adult visible phenotype; almost approaching the cytokinin hypersensitivity of the arr3,4,5,6,8,9 hextuple mutant but significantly less sensitive than arr3,4,5,6,8,9 at 5 and 10 nM benzyladenine (BA); intermediate cytokinin sensitivity in seedling lateral root formation, between the wild type and the arr3,4,5,6,8,9 hextuple mutant, with the sensitivity of arr3,4,8,9 closest to arr3,4,5,6,8,9.
• CS25279  — Intermediate petiole length between arr3,4,5,6 and the wild type (suggesting complex interactions between these genes); roots are shorter and have significantly fewer lateral roots than the wild type in the absence of exogenous cytokinin; increased cytokinin hypersensitivity in seedling root elongation, seedling lateral root formation, hypocotyls/ shoot initiation and leaf senescence delay; decreased sensitivity to red light compared to wild type.
