From: Functions of CsGPA1 on the hypocotyl elongation and root growth of cucumbers
Cross and longitudinal sections of 6-d-old WT and transgenic cucumber seedlings grown in darkness. Hypocotyl cross sections of (a) OE line 97, (b) WT, and (c) RNA line 10. Magnified images of the hypocotyl cross sections of (d) OE line 97, (e) WT, and (f) RNAi line 10 were analyzed. Scale = 100 µm. EP, external phloem; IP, internal phloem; X, xylem; PP, parenchymal cell; BS, vascular bundle sheath; CC, companion cell; SE, sieve element. Longitudinal sections of the hypocotyls in (g) OE line 97, (h) WT, and (i) RNAi line 10. The dotted lines indicate the direction of the bending and the arrows indicate sieve element cells. (j) Average single cell area in the first layer of parenchymal cells in hypocotyl. (k) Average number of cells per 0.5 mm2 in hypocotyl. (n = three visual fields). Values that differed significantly from the WT values are indicated. *p < 0.05 and according to a Bonferroni post-hoc test.
