Expression of NtZFL in tobacco plant in response to biotic and abiotic stress was studied by QRT-PCR, the results showed that NtZFL was responsive to the treatments of MV, H2O2, ABA and cold. Northern blot analysis showed that NtZFL gene was expressed in different tissues of tobacco plant, achieving maximum in the young leaves and flowers. Subcellular localization analysis showed that the NtZFL protein was localized in the cell wall. GUS activity driven by NtZFL promoter was expressed in the whole of the young plant, but strongly detected in roots and leaf veins. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2012.04.010
