      Unconventional peptides (NCP) include peptides encoded by small open reading frames and play a key role in basic biological processes. Here, we have developed an integrated peptide genomics pipeline using high throughput mass spectrometry technology to probe the customized six-frame translation database and apply it to large-scale identification of NCP in plants. 1 993 and 1 860 NCP were identified in maize and Arabidopsis respectively. Compared with conventional peptides (CP), NCP shows unique characteristics and is derived from introns, 3 'UTR, 5' UTR, junctions and intergenic regions. These results show that the range of translation events in unannotated transcripts is wider than previously thought.

In addition, maize NCPs are enriched in regions related to phenotypic variation and domestication selection, indicating their potential functions in complex traits and evolutionary plant genetic regulation. To sum up, this study provides an unbiased and global view of plant NCP. Identification of large-scale NCP in monocotyledonous plants and dicotyledonous plants shows that a large part of plant genomes can be transformed into biological functional molecules, which is of great significance in functional genome research. This study also provides useful resources for characterizing more hidden NCPs in other plants.
