Figure 5.

Transverse sections of secondary roots of wild-type (A) and GAS:BEL5 (B) plants. Plants were grown under short-day conditions, and roots were harvested at the 12- to 13-leaf stage. Sixteen or 17 sections were examined for each line. These sections came from random root pieces from three to four plants of each line. These micrographs are representative of each type. Sections were viewed and photodocumented with an Olympus BX40 microscope and a Carl Zeiss AxioCam MRc 5 digital camera. Cor, Cortex; Ph, phloem; Xy, xylem. The arrows show the separation of the xylem triarch that occurs in secondary roots of GAS:BEL5 plants (B) but not the wild type (A).
