Mycorrhization.

(a) Real time PCR confirmed increased mycorrhizal colonization and function. Reduced SlSUT2 expression (blue) is accompanied by increased gene expression of the fungal RiGAPDH (green) or the mycorrhization-specific phosphate transporter gene SlPT4 (red). ***p < .001; **p < .01; *p < .05. (b) Arbuscules of SlSUT2-RNAi #27 show a high number of septa (arrows). (c) Tubule diameter of arbuscule branches is reduced in SlSUT2-RNAi plant. The diameter of the finest arbuscular branches was analyzed using the confocal Zeiss software ZEN 2.0 blue edition. In case of WT plants, 15 tubules from 4 different arbuscules in 8 different plants were measured (n = 480), in case of transgenic SlSUT2-RNAi plants, 15 tubules from 4 different arbuscules in 3 different plants per transgenic line were measured (n = 180). The tubule diameter of finest arbuscular branches was significantly reduced in two out of four SlSUT2-RNAi plants (*p < .05).
