From: GhLTPG1, a cotton GPI-anchored lipid transfer protein, regulates the transport of phosphatidylinositol monophosphates and cotton fiber elongation

Figure 1

GhLTPG1 is expressed in elongating cotton fibers and outer integument of cotton ovules.

(a) GhLTPG1 highly expresses in the ovules since cotton fibers initiate at 0 DPA and lowly expresses in the ovules before 0 DPA (DPA, days post anthesis), roots (R), stems (S) and leaves (L). (b) GhLTPG1 gene expression significantly increases in the ovules of Xu142 when fiber elongates (3 DPA) and no obvious expression change occurred in the ovules of Xu142fl (Xu142 fiberless and lintless mutant). (c) GhLTPG1 gene mainly expresses in the fiber cells and outer integument of cotton ovule. GhLTPG1 antisense probe detected GhLTPG1 gene expression specific in the fibers and outer integument of Xu142 ovule at 3 DPA. Arrowhead indicates GhLTPG1 expression signal (deep blue). No hybridization signal was observed in the Xu142fl ovule compared with Xu142 (arrowhead indicates no hybridization signal in osc). The sense probe displayed no signal in the ovule of Xu142, as the negative control. The bottom pictures are 10 times magnified images of corresponding upper panels respectively. f, fiber; isc, inner seed coat; osc, outer integument of seed coat. Scale bars: 200 μm in upper images (c); 100 μm in lower images (c).
