Figure 2.

Organ-specific expression pattern for OXP1. The accumulation of OXP1 mRNAs in Columbia wild-type plants is shown. Rosette leaves from soil-grown 3-, 4-, 5-, and 7-week-old plants, cauline leaves, stems, and flowers from soil-grown 7-week-old plants, and siliques (2–4 d after flowering [DAF]) and roots of liquid-cultured 12-d-old plants were harvested and total RNA was extracted. RNA was reverse transcribed and subjected to real-time PCR analysis to monitor the amplification of OXP1 cDNAs. The accumulation of OXP1 mRNAs relative to that of ACTIN was determined. Values are normalized with the means of rosette leaves from 3-week-old plants. Means and sd values of three independent biological replications are shown.
