This proposal is aimed at testing probiotic microbes and microbial-based diagnostic technologies to reduce the use of synthetic pesticides and nitrogen fertilizer in crop production. Similar to microbes that live inside the human intestine that help to digest milk, plants are inhabited by potentially beneficial microbes, referred to by plant scientists as endophytes. Endophytes are typically bacteria and fungi, and they can assist their host organisms to acquire nutrients, tolerate environmental stress or combat pathogens. We have successfully bioprospected for 250 endophytes from cereals and shown under indoor conditions that they can benefit Canadian corn and wheat (by suppressing Fusarium diseases). The first objective of this proposal is to test these potential probiotics under field conditions, as the first step towards commercialization. Global agbiotech companies have decided that such biologicals will be a major part of their growth strategy, and hence this proposal will help Canada to become a global leader in this job-creating sector. Second, we have engineered a microbe to act as a diagnostic tool (biosensor) with the goal of helping farmers to more effectively use nitrogen fertilizer, in order to improve farmer incomes and reduce environmental damage. This proposal will extend this laboratory test, which has been issued a US patent, into real world field conditions. Combined, this proposal will explore the use of beneficial microbes to assist Canadian grain farmers.

该提案旨在测试益生菌和基于微生物的诊断技术，以减少作物生产中合成农药和氮肥的使用。与生活在人类肠道内帮助消化牛奶的微生物类似，植物中也居住着潜在的有益微生物，植物科学家称之为内生菌。内生菌通常是细菌和真菌，它们可以帮助其宿主生物获得营养，耐受环境压力或对抗病原体。我们已经成功地对250种来自谷物的内生菌进行了生物勘探，并在室内条件下表明它们可以使加拿大玉米和小麦受益（通过抑制镰刀菌疾病）。该提案的第一个目标是在田间条件下测试这些潜在的益生菌，作为商业化的第一步。全球农业生物技术公司已决定将此类生物制品作为其增长战略的重要组成部分，因此，这一提议将有助于加拿大成为这一创造就业机会领域的全球领导者。其次，我们设计了一种微生物作为诊断工具（生物传感器），目的是帮助农民更有效地使用氮肥，以提高农民收入并减少环境破坏。该提案将把已获得美国专利的实验室测试扩展到真实的世界现场条件。结合起来，这项提案将探索使用有益微生物来帮助加拿大粮农。
