Unsurprisingly, random probe-pair removal also affected probe-set expression estimates.
Random probe-pair removal of 1, 2, 5, 10, 20, 50, 75 and 90% of probe-pairs was repeated three times on one of the Arabidopsis gDNA.cel files.
Random probe-pair removal increased the number of genes identified as significantly differentially expressed (P < 0.05) compared to corresponding gDNA-based probe-masks, especially when a large proportion of the probe-pairs were removed from the analysis.
The effects of gDNA-based probe removal on estimates of gene expression differences was compared to the effects of random removal of probe-pairs using Arabidopsis Data Set B. Software to simulate random probe-pair removal (Xspecies Version 2.0) has been developed and is freely available [ 31].
Importantly, under certain conditions, RNA-MoIP allows base pair removals to insert the 3D motifs.
Samples were then averaged across two dye flip replicate pairs with removal of zero/dropped values using locally developed averaging software from the BEAR microarray suite (M. Datta, submitted).
In these two instances, mismatches are converted to standard base pairs via removal and replacement of nucleotides at the 3′-end of the transcript, rather than at the 5′-end, as in a number of other tRNA editing systems (Lonergan and Gray 1993a, 1993b; Laforest et al. 1997).
We then randomly assigned each brood to one of two maternal care treatments: either widowed females were removed from their breeding box around hatching (roughly 71 hr after pairing) or removal occurred 24 hr after hatching (roughly 95 hr after pairing).
Several genes, particularly Ph1, are known to block or enhance homoeologous pairing; with removal of this locus shown to induce novel pairing and recombinational behaviour.
Conservation within these regions of EbrA/EbrB support site-directed mutagenesis experiments of Bsu-EbrA and Bsu-EbrB that demonstrate the importance of the loop and C-terminus regions on protein function as a pair; their removal in either EbrA or EbrB resulted in individual variants that could confer isogenic resistance to the host [ 23].
