Figure Lengend Snippet: Promoter activity was detected in the vascular bundles of uninoculated P. vulgaris roots (A), and in emerging lateral root primordia (B, D, E, F). Promoter activity was also detected in root hairs of uninoculated roots (C). The spatiotemporal expression pattern of the PvCRT08 promoter was monitored in transgenic roots after-inoculation with R. tropici DsRed (G–J). (G) Infection site at 5 dpi. (H) Nodule primordium at 7 dpi. (I and J) Mature nodules at 21 dpi. (J) Free-hand sections of nodules at 21 dpi. RH: root hair; IT: infection thread; CCD: cortical cell division; IC: infected cell.
Article Snippet: To develop a p PvCRT08 :GUS-GFP construct, a 2086-bp fragment upstream of the PvCRT08 translation start site was amplified using bean genomic DNA and primers p PvCRT08 -Up and p PvCRT08 -Lw ( Table S6 ) and cloned into vector pENTR/SD/D-TOPO (Invitrogen).
