The triphosphate tunnel metalloenzyme (TTM) superfamily represents a group of enzymes that is characterized by their ability to hydrolyze a range of tripolyphosphate substrates. Arabidopsis (Arabidopsis thaliana) encodes three TTM genes, AtTTM1, AtTTM2, and AtTTM3. Although AtTTM3 has previously been reported to have tripolyphosphatase activity, recombinantly expressed AtTTM2 unexpectedly exhib...

The 2004 Harvest Survey of Canadian canola (1) had higher than average chlorophyll content due to a cooler than normal season combined with an early damaging frost resulting in immature seed. As a result, chlorophyll levels in many No. 1 Canada Canola (1CC) export shipments increased to over 30 mg/kg (2). Dockage has been suspected in contributing to the chlorophyll levels in canola cargoes but...

In total, 140 halotolerant bacterial strains were isolated from both the soil of barren fields and the rhizosphere of six naturally growing halophytic plants in the vicinity of the Yellow Sea, near the city of Incheon in the Republic of Korea. All of these strains were characterized for multiple plant growth promoting traits, such as the production of indole acetic acid (IAA), nitrogen fixation...

Gene flow from transgenic glyphosate-resistant crops can result in the adventitious presence of the transgene, which may negatively impact markets. Gene flow can also produce glyphosate-resistant plants that may interfere with weed management systems. The objective of this article is to review the gene flow literature as it pertains to glyphosate-resistant crops. Gene flow is a natural phenomen...

Brassica napus Linnaeus is considered a self-compatible crop; however, studies show that bee foraging elevates their seed production. Considering bee food shortages during the winter season and that the canola is a winter crop, this study aimed to evaluate the foraging behaviour of Apis mellifera Linnaeus, 1758 regarding those flowers, and to verify if it presents adequate behaviour for success...

Regeneration of explants plays a significant role in plant transformation. Explant type, hormonal concentration, and pre-culturing period are important in transformation efficiency. To get an efficient transformation of canola and optimize regeneration conditions, different explants along with different culture media were studied. Four canola varieties were used to evaluate regeneration ability...

Canola oil was transesterified using a 1 : 1 molar mixture of methanol and ethanol (M/E) with potassium hydroxide (KOH) catalyst. The effects of catalyst concentration (0.5–1.5 wt-%), molar ratio of M/E to canola oil (3 : 1 to 20 : 1) and reaction temperature (25–75 7C) on the percentage yield measured after 2.5 and 5.0 min were optimized using a central composite design. A maximum percentage y...

In order to assess relationship between ion transport and variation in growth responses of four canola cultivars under salt stress, four canola cultivars were grown at 0 and 150 mM NaCl for six weeks in hydroponics. Salt stress reduced the shoot and root fresh and dry weights of all canola cultivars. Maximum shoot fresh and dry weights were recorded in Dunkeld under both non-saline and saline c...

Endogenous sinapic acid (SA), sinapine (SP), sinapoyl glucose (SG) and canolol (CAN) of canola and mustard seeds are the potent antioxidants in various lipid-containing systems. The study investigated these phenolic antioxidants using different fractions of canola and mustard seeds. Phenolic compounds were extracted from whole seeds and their fractions: hulls and cotyledons, using 70% methanol ...
