Table 4 Numbers of different cis-NATs with RNA structures*

From: The distribution and evolution of Arabidopsis thaliana cis natural antisense transcripts

  P > 0.5 P > 0.5 ** P > 0.8 P > 0.9
TAIR data set 12/55 (22%) 6/55 (11%) 7/55 (13%) 5/55 (9%)
2/55 (4%) ¶, 2/55 (4%) 1/55 (2%) 1/55 (2%)
Matsui2008 71/1365 (5%) ¶ -- 46/1365 (3%) 32/1365 (2%)
Okamoto2010 22/485 (5%) ¶ -- 13/485 (3%) 10/485 (2%)
  1. * The fractions are of the totals that have significant sequence conservation. For the TAIR data, the first row is for RNAz calculations across the whole NOLP sequence. For non-TAIR data and for the second row for the TAIR data, these are cases that overlap CNSs (conserved non-coding sequences) identified in Haudry, et al. [21].
  2. ** Removing non-significantly conserved cases after Holm-Bonferroni correction.
  3. ¶ The total numbers of conserved are significantly enriched compared to randomly sampled near-gene DNA (P = 0.046 for the TAIR set, P < 0.00001 for the other two sets, normal statistics). To assess this, for each of the three actual data sets listed, 500 samples of near-gene DNA of the same distribution of sizes and position relative to neighbour genes as the actual set were generated (as described in the Methods ).
