XPL1 Expression Pattern Revealed by Whole Mount RNA in Situ Hybridization.

The presence of XPL1 transcripts is visible as a purple precipitate. Nomarski optics images of different regions of 7-d-old Col 0 seedlings hybridized with the sense ([A] to [C]) or antisense ([D] to [F]) probes for XPL1. The expression pattern observed in the root meristem and elongation zone (D) and differentiated epidermal cells of seedlings incubated over night with the phosphatase substrates (E) compared with their respective controls ([A] and [B]). The expression pattern of XPL1 observed in specific cell layers of the elongation zone and the root meristem (F), and the respective control (C), in seedlings incubated for 1 h with the phosphatase substrates.
