Imported genetically modified (GM) canola (Brassica napus) is approved by Japanese law. Some GM canola varieties have been found around importation sites, and there is public concern that these may have any harmful effects on related species such as reduction of wild relatives. Because B. juncea is distributed throughout Japan and is known to be high crossability with B. napus, it is assumed to...

Daratan Papua memiliki keanekaragaman hayati yang unik. Keunikan tersebut disebabkan karena terletak dibawah garis khatulistiwa terdapat hutan hujan tropis dengan keragaman species flora tinggi, salah satunya adalah lebah madu. Masyarakat Lembah Baliem Wamena Kabupaten Jayawijaya pada umumnya bermukim di dataran rendah, selah-selah gunung, bawah kaki gunung dan diatas ketinggian 1.600 – 3.500...

Haploids and doubled haploids are invaluable for basic genetic studies and in crop improvement. A novel method of haploid induction through genetic engineering of the Centromere Histone Protein gene, CENH3, has been demonstrated in Arabidopsis. The present study was undertaken to develop haploid inducer (HI) lines of Brassica juncea based on the principles elaborated in Arabidopsis. B. juncea w...

Several imported transgenic canola (Brassica napus) seeds have been spilled and have grown along roadsides around import ports. B. juncea, a relative of B. napus with which it has high interspecific crossability, is widely distributed throughout Japan. There is public concern about the harmful impacts of feral B. napus plants on biodiversity, but spontaneous hybridization between spilled B. nap...

Tocopherols (vitamin E) are lipid soluble antioxidants synthesized by plants and some cyanobacteria. We have earlier reported that overexpression of the gamma-tocopherol methyl transferase (gamma-TMT) gene from Arabidopsis thaliana in transgenic Brassica juncea plants resulted in an over six-fold increase in the level of alpha-tocopherol, the most active form of all the tocopherols. Tocopherol ...

ALLYL ISOTHIOCYANATE DERIVED FROM ORIENTAL MUSTARD MEAL AS A NATURAL ANTIMICROBIAL TO INHIBIT THE GROWTH OF MOULDS ON BREAD Jianhua Ma Advisor University of Guelph, 2012 Dr. Keith Warriner This thesis is an investigation of the potential of Allyl Isothiocyanate (AITC) derived from oriental mustard meal (Brassica juncea meal) as a natural preservative suppression moulds growth on bread. Currentl...

Defatted meals and protein concentrates from six accessions of Sinapis alba and one accession of Brassica juncea mustard seeds were analysed for their polypeptide profile and functional properties. Two types of protein concentrates were prepared using acid-induced and calcium-induced protein precipitations. Meals from the S alba seeds had similar polypeptide composition, which was different fro...
