    Structures of the three homoeologous loci of wheat benzoxazinone biosynthetic genes TaBx3 and TaBx4 and characterization of their promoter sequences

    Common wheat (2n = 6x = 42, genome formula AABBDD) accumulates benzoxazinones (Bxs) as defensive compounds. There are five Bx biosynthetic genes (TaBx1–TaBx5), and their homoeologous alleles are located on all th...

    Rearrangement of the genes for the biosynthesis of benzoxazinones in the evolution of Triticeae species

    Gramineous plants, including the major agricultural crops wheat (Triticum aestivum L.), rye (Secale cereale L.) and maize (Zea mays L.), accumulate benzoxazinones (Bxs) as defensive compounds. Previously, we isol...

    Development of a rapid method for identifying asparagus super-males using, N-(4-chloro-2-trifluoromethylphenyl)-N'- propoxyacetamidine to induce flowering

    In order to shorten the term for the identification of asparagus super-maleplants, a method usingN-(4-chloro-2-trifluoromethylphenyl)-N'-pro-poxyacetamidine (AM12) toinduce flowering was developed. This method...

    Purification and characterization of a hydroxamic acid glucoside β-glucosidase from wheat (Triticum aestivum L.) seedlings

     A β-glucosidase (EC 3.2.1.21) with a high affinity for cyclic hydroxamic acid β-d-glucosides was purified from 48-h-old wheat (Triticum aestivum L.) seedlings. The activity occurred transiently at a high level d...

    Induction of biosynthetic enzymes for avenanthramides in elicitor-treated oat leaves

    The accumulation of oat (Avena sativa L.) phytoalexins, avenanthramides, occurred in leaf segments treated with oligo-N-acetylchitooligosaccharides. The amount of avenanthramide A, the major oat phytoalexin, rea...
