Cloned(Commentary)

Cloned (Comment) Organism
the flanking sequences of the mutant bt2-H2328 are cloned and sequenced Zea mays

Protein Variants

Protein Variants Comment Organism
bt2-H2328 mutant, an insertion is located in exon 6 of the Bt2 gene generating a 9-bp duplication of bases TGATGTGAC, position 4,422 - 4,431, a comparative transcriptome analysis of wild-type and bt2-H2328 kernels at mid-development leads to the conclusion that the lack of Bt2-encoded AGPase triggers large-scale changes on the transcriptional level that concern mainly genes involved in carbohydrate or amino acid metabolic pathways Zea mays
