Ectopic-expression of SAG12::IPT induces cytokinin content both in leaves and roots. a Ectopic expression of SAG12::IPT induces Z/ZR-type cytokinin content in the third true leaf of OE3 and OE8. The third true leaf (0.5 g) of transgenic lines and control cotton were collected after one, three and six days 220 mmol·L− 1 NaCl treatment to detect Z/ZR-type cytokinin content. b Ectopic expression of SAG12::IPT induces iP/iPA-type cytokinin content in the third true leaf of OE3 and OE8. The samples were collected as (a). c Ectopic expression of SAG12::IPT induces Z/ZR-type cytokinin content in roots of OE3 and OE8. The root samples (0.5 g) of transgenic lines and control cotton were collected after one, three and six days 220 mmol·L− 1 NaCl treatment to detect Z/ZR-type cytokinin content. d Ectopic expression of SAG12::IPT induces iP/iPA-type cytokinin content in roots of OE3 and OE8. The samples were collected as (c). The data are shown as means ± SD from three repeats (n = 3, *P ≤ 0.05)
