Improvement of whole-genome annotation of cereals through comparative analyses.

ABSTRACT: Rice is an important model species for the Poaceae and other monocotyledonous plants. With the availability of a near-complete, finished, and annotated rice genome, we performed genome level comparisons between rice and all plant species in which large genomic or transcriptomic data sets are available to determine the utility of cross-species sequence for structural and functional annotation of the rice genome. Through comparative analyses with four plant genome sequence data sets and transcript assemblies from 185 plant species, we were able to confirm and improve the structural annotation of the rice genome. Support for 38,109 (89.3%) of the total 42,653 nontransposable element-related genes in the rice genome in the form of a rice expressed sequence tag, full-length cDNA, or plant homol
