Potential source-specific, highly expressed genes identified by EST profiles
| Source (Project) | No. of Contigs | No. of ESTs | Example of Gene Products |
|---|---|---|---|
| Leaf primordia (486) | 7 | 47 | Thioredoxin peroxidase (13 ESTs), cystathionine gamma-synthase (eight ESTs) |
| 10- to 14-d-old Endosperm (605) | 24 | 311 | Zein (two TUCs, 83 ESTs total) |
| 1- to 2-cm Immature ear (606) | 4 | 25 | MADS box protein (seven ESTs) |
| 4-d-old Root (614) | 46 | 307 | Glutamic acid-rich protein precursor (14 ESTs) |
| <2-cm Tassel (618) | 1 | 8 | No significant match |
| Mixed tassel stages (660) | 15 | 112 | Dihydroflavonol reductase (16 ESTs), expansin 1 (11 ESTs) |
| Mixed embryo stages (687) | 10 | 103 | Early embryogenesis protein (35 ESTs), peroxiredoxin (13 ESTs) |
| Mixed adult organs (707) | 30 | 213 | Photosystem II 10-kD polypeptide (16 ESTs), Cys proteinase precursor (15 ESTs) |

Columns two and three give the no. of contigs and total no. of ESTs in these contigs for contigs with at least five ESTs solely from the source indicated in column one. Column four gives one or two examples of corresponding putative gene products, inferred on the basis of high sequence similarity, for contigs with the highest number of ESTs.
