MPSS expression values for maize rops in tissues also assayed by MTRP. MPSS values for each experimental sample are normalized to parts per million; error bars represent 95% confidence intervals for experiments sampling identical numbers of signatures (Audic and Claverie, 1997), also normalized to parts per million. Expression values shown in A are for rops in the shoot apex (shoot apical meristem, immature leaf) and mature leaf (compare with SA and ML in Fig. 6), and in B, in the tassel and mature pollen (compare with P in Fig. 6). Total number of signatures determined in each experiment: shoot apical meristem, 1,243,089; immature leaf, 1,191,133; mature leaf, 923,217; immature tassel, 1,082,651; tassel, meiosis stage, 1,325,062; mature pollen, 280,724.
