Salinity response of SlIPT3 and SlIPT4 in Arabidopsis. Germination percentage (A) and survival percentage (B) of SlIPT4 (lines 3AT and 5AT) and SlIPT3 (lines 9AT and 10AT) Arabidopsis ipt3 complemented plants. **significantly lower germination and survival percentages compared to ipt3 KO. ***significantly lower survival percentages compared to WT and ipt3 KO. (C) Primary root length of Arabidopsis SlIPT3 and SlIPT4 complemented plants. *significantly longer primary root compared to WT. **significantly shorter primary root compared to WT. ***significantly shorter primary root compared to ipt3 KO plants (Mann–Whitney U Test with p ≤ 0.05).
