Expression feature representation among annotated genes and Ψs
| Expression Tag Type | No. of Annotated Genes with Tagsa | Percentage of Annotated Genes with Tagsb | No. of Ψs with Tagsc | Percentage of Ψs with Tags |
|---|---|---|---|---|
| PUT | ||||
| Arabidopsis | 19,460 | 71.9 | 162 | 2.1 |
| Rice | 20,442 | 49.8 | 135 | 2.8 |
| MPSS | ||||
| Arabidopsis | 19,764 | 73.1 | 233 | 4.9 |
| Rice | 20,091 | 48.9 | 200 | 2.6 |
a
Annotated genes are Arabidopsis or rice genes in TAIR version 7 and TIGR version 5 annotations. A PUT was matched to an annotated gene if the PUT-gene pair had 97% or greater identity over 50% or more of the shorter sequence with length of 300 bp or greater. Only MPSS tags with a 100% unique match to genes were considered.
b
The numbers of annotated protein genes in Arabidopsis (TAIR version 7) and rice (TIGR version 5) are approximately 41,030 and 27,029, respectively (after excluding annotated Ψs and repetitive elements).
c
The numbers of set II Ψs in Arabidopsis (TAIR version 7) and rice (TIGR version 5) are 3,697 and 7,762, respectively.
