Transient expression of DlXTH23.5/25 in tobacco and functional verification of DlXTH23.5/25 with associated transcription factors (TFs). (A) Multiple sequence alignment of the DlXTH23.5/25 protein. (B) Subcellular localization of the DlXTH23.5–GFP and DlXTH25–GFP fusion proteins in tobacco leaves. Free GFP served as a control. CW, cell wall; CM, cell membrane. Scale bar = 20 μm. (C) Xyloglucan content during early somatic embryogenesis (SE) in longan. (D) Left: Xyloglucan content in wild-type and DlXTH23.5/25-overexpressing leaves. Right: Xyloglucan content in wild-type and DlWRKY31- and DlERF1/5-overexpressing leaves (Student’s t-test, *P < 0.05, **P < 0.01).
