NASC ID: N25276

Name: arr3,4,5,6

ABRC stock number: CS25276

Description: Quadruple mutant with insertions in ARR3, ARR4, ARR5 and ARR6; kanamycin resistant; The elongated petioles of arr4 and arr3,4 are enhanced, but the overall rosette size is similar to that of the wild-type parent; the increased petiole elongation suggests that although ARR5 and ARR6 may act antagonistically to each other in regulating rosette size, as a pair they still function additively with ARR3 and ARR4 in the regulation of petiole elongation; root elongation responses intermediate between arr3,4,5,6,8,9 and the wild type, but significantly more sensitive than arr3,4; 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; increased sensitivity to red light..
