Although limited in some aspects, the comparison to maize indicates that all data acquired on one C4 species cannot always be easily extrapolated to other species.
The relatively larger numbers of NAS genes in barley and maize indicates that NAS may duplicate and evolve during the emergence of new species and breeding process.
Similar analysis of the PAB7 ortholog in maize indicates that its expression is restricted to anthers and is expressed during the mid to late stage of endosperm development but not expressed in embryos (MaizeGDB; http://www.maizegdb.org).
A recent risk assessment by Wolt et al. (2006) of human exposure to LT-B in transgenic maize indicates that a dose 200-fold lower than a functional dose in humans is small enough to consider that maize unadulterated from a toxicologic perspective.
A detailed comparison of QTL for flowering in Setaria, sorghum, and maize indicates that several of the major QTL regions identified in maize and sorghum are syntenic orthologs with Setaria QTL, although the maize large effect QTL on chromosome 10 is not.
As a generalisation, while clade GH9B1 and GH9A contain introns 1 and 6, the remainder of the endo- 1,4 -β-glucanase gendo- 1,4 -β-glucanase and 7. A closendo- 1,4 -β-glucanasetructurendo- 1,4 -β-glucanasehat intron 7 is not present, but it is seen in three of four rice genesgenes.
