Figure 5

Microscopic images of frozen sections of Trichosanthes kirilowii rhizoids at different induction stages.

(A) Longitudinal section of a rhizoid. (A1) Transverse section of a rhizoid showing cortex and potential cell division pool at an early stage. (B) Longitudinal section of a rhizoid after one-day incubation on RTB induction medium. (B1) Transverse section of a rhizoid after one-day incubation on RTB induction medium, showing cortex and potential fast-cell-division zone (FCDZ) at an early stage. (C) Longitudinal section of a rhizoid after two-day incubation on RTB induction medium. (C1) Transverse section of a rhizoid after two-day incubation on RTB induction medium, showing cortex and potential FCDZ at an early stage. (D) Longitudinal section of a rhizoid after three-day incubation on RTB induction medium. (D1) Transverse section of a rhizoid after three-day incubation on RTB induction medium, showing cortex and potential FCDZ at an early stage. Scale bars for (A, A1, B, B1, C, C1, D and D1), 300 μm.
