INNOVATING CRANBERRY FARMING WITH BENEFICIAL SYMBIOTIC MICROBESCranberry products are a multi-billion dollar business worldwide. Canada's share of the global conventional production is ~25%, and 90% of organically grown fruit. However, cranberry farming is faced with complex challenges including plant diseases that are exacerbated by climate change. We propose to counter these challenges by deploying beneficial microbes living within cranberries (symbionts), notably fungal and bacterial microorganisms. In fact, numerous agricultural plants host similarly beneficial microbes, such as Rhizobium bacteria in legumes, and mycorrhizal fungi in a large variety of crop plants.Our goal is to isolate symbiotic microbes that suppress pathogens (biocontrol), deliver phosphorus, nitrogen and other nutrients into cranberry plants (biofertilization), secrete compounds that stimulate plant growth, and improve resistance to stress (high or low temperatures; drought). The objective of this proposal is to undertake rigorous field trials with select microbes previously isolated and characterized in our laboratory, and to investigate properties of a set of new microbe isolates, which as well will be tested in field experiments. Development of beneficial cranberry-specific symbionts will take Canadian cranberry farming to the next level, strengthen the industry, alleviate the environmental impact of cranberry farming by reducing agrochemicals, and advance our understanding of symbiont-plant interactions.

用有益的共生微生物革新蔓越莓农业蔓越莓产品是全球数十亿美元的业务。加拿大占全球传统水果产量的25%，有机水果产量的90%。然而，蔓越莓种植面临着复杂的挑战，包括因气候变化而加剧的植物疾病。我们建议通过部署生活在蔓越莓（共生体）中的有益微生物来应对这些挑战，特别是真菌和细菌微生物。事实上，许多农业植物都有类似的有益微生物，如豆类植物中的根瘤菌，以及多种农作物中的菌根真菌。我们的目标是分离抑制病原体的共生微生物（生物控制），将磷，氮和其他营养物质输送到蔓越莓植物中（生物施肥），分泌刺激植物生长的化合物，并提高对胁迫（高温或低温;干旱）的抗性。该提案的目的是对我们实验室先前分离和表征的选定微生物进行严格的田间试验，并研究一组新微生物分离株的特性，这些分离株也将在田间试验中进行测试。有益的蔓越莓特定共生体的开发将使加拿大蔓越莓农业更上一层楼，加强该行业，通过减少农用化学品来减轻蔓越莓农业对环境的影响，并促进我们对共生体-植物相互作用的理解。
