As part of a project to identify novel maize (Zea mays L. cv B73) genes
functionally, we have partially sequenced 130 randomly selected clones from
a maize leaf cDNA library. Data base comparisons revealed seven previously
sequenced maize cDNAs and 18 cDNAs with sequence similarity to related
maize genes or to genes from other organisms. One hundred five cDNAs show
little or no similarity to previously sequenced genes. Our results also
establish the suitability of this library for large-scale sequencing in
terms of its large insert size, proper insert orientation, and low
duplication rate.
