In agricultural environments where canola (Brassica napus) is grown, slow germination can increase the susceptibility of seedlings to pathogens, delay maturity, and decrease yield. Bacterial products that enhance germination have been identified for a variety of plants. Three signal molecules were investigated: Bradyrhizobium japonicum 532C product(More)
Peat moss has been a standard carrier of inoculum for experimentation and in agriculture. Peat moss is, however, a non-renewable resource. Alternatively, biochar could serve as an inoculum carrier. Here, we tested the effect of biochar-based seed coatings as a carrier for the phosphorous-solubilizing Pseudomonas libanensis inoculum, on corn growth after(More)
Recent work has shown that plant-to-microbe signals can enhance the growth of a wide range of crops. Nevertheless, canola (Brassica napus L.), which forms neither arbuscular mycorrhizal nor nitrogen-fixing symbioses, has not been rigorously evaluated for its capacity to perceive and respond to microbe-to-plant signals. It was shown previously that the(More)
The objective of this experiment was to assess whether or not the application of lipo-chitooligosaccharide (Nod Bj V [C18:1, MeFuc]) (LCO) would increase yield factors under conditions that would inhibit canola (Brassica napus L.) productivity. The seed application reduced the percentage of plants that were unproductive by 15.10% compared to plants grown(More)
Microbe-to-plant signals can enhance the growth of a wide range of crops. The responses by soybean (Glycine max var. 91M01) to 2 signal molecules were investigated: Bradyrhizobium japonicum 532C lipo-chitooligosaccharide (Nod Bj V [C:18, MeFuc]) (LCO); and Bacillus thuringiensis strain NEB17 bacteriocin thuricin 17 (Th17). The objective was to assess and(More)
Lipo-chitooligosaccharides (LCOs) are signal molecules that play a role in initiating the symbiotic legume-rhizobia and arbuscular mycorrhizal processes. Thuricin 17 is a bacteriocin produced by Bacillus thuringiensis strain NEB 17. Previous work has shown that the application of a 10−6 M LCO solution, or a 10−11 M thuricin 17 solution, can stimulate the(More)
