KNL2pro Activity in Arabidopsis during Development.

(A) IMEter scores, indicating predicted intron mediated enhancement of transcription, for all introns of KNL2 as determined by in silico analysis using the IMEter online program (Rose et al., 2008).

(B) Scheme of the KNL2pro:GFP-GUS reporter gene construct.

(C) to (M) Histochemical localization of GUS activity in Arabidopsis plants transgenic for AtKNL2pro:GFP-GUS: 4-d-old (C) and 7-d-old (D) seedling as well as their primary root tips ([E] and [F]). Fourteen-day-old seedling (G), inflorescences ([H] and [I]), mature flowers ([J] and [K]), and siliques ([L] and [M]) at different developmental stages.
