Inocucor Technologies Inc. (Inocucor) is a Canadian company specializing in the development of sustainableplant-microbial agricultural products. Healthy soils include proliferating communities of plantgrowth-promoting bacteria which contribute to higher crop yields. Therefore, enriching soils with the beneficialbacterial communities and treating plants with biostimulants represent products provided by Inocucor. TheCompany's 1st generation IN-M1 product is currently on sale in 22 US states for high value produce and theCompany's 2nd generation product is registered in 15 states for row crops. Since global temperatures are on therise, Canadian farmers have been experiencing warmer than usual growth seasons. Although warmertemperatures may increase photosynthetic activity and cause earlier reproductive development, the yield willnot necessarily increase due to reduced soil water content. This will induce photoinhibition of photosynthesiswhich reduces rates of photosynthesis, plant growth and seed yield. Recent results indicated that application ofIN-M1 to wheat plants grown at higher than normal temperatures likely increases leaf chlorophyllaccumulation. Furthermore, winter but not spring wheat plants grown at higher than normal temperatures andtreated with IN-M1 had increased seed yield by up to 40%! Inocucor would like to confirm the link betweenIN-M1 product, shoot photosynthesis and grain yield in response to higher than normal growth temperaturespredicted to be associated with global warming. The company expects that the proposed research will provide ablueprint information that can then be used to design new bacterial soil biostimulants to improve the yield ofheat and drought stressed crops that will have the potential to benefit Canadian agriculture.

Inocucor Technologies Inc.(Inocucor)是一家加拿大公司，专门从事可持续植物微生物农产品的开发。健康的土壤包括促进植物生长的细菌群落，它们有助于提高作物产量。因此，用有益的细菌群落丰富土壤和用生物刺激剂处理植物是Inocucor提供的产品。该公司的第一代IN-M1产品目前在美国22个州销售，用于高附加值产品，该公司的第二代产品在15个州注册用于行作物。由于全球气温上升，加拿大农民经历了比往常更温暖的生长季节。尽管变暖的温度可能会增加光合作用活性，导致生殖发育提前，但产量并不一定会因为土壤水分的减少而增加。这将导致光合作用的光抑制，从而降低光合作用、植物生长和种子产量。最近的结果表明，在高于正常温度下生长的小麦植株上应用In-M1可能会增加叶片的叶绿素积累。此外，在比正常温度更高的温度下生长的冬小麦植株和IN-M1处理的小麦植株种子产量增加了40%！Inocucor想要确认IN-M1产物、地上部光合作用和谷物产量之间的联系，以响应高于正常生长温度的预测与全球变暖有关的温度。该公司预计，拟议的研究将提供指纹信息，然后可用于设计新的细菌土壤生物刺激剂，以提高高温和干旱胁迫下作物的产量，这些作物将有可能使加拿大农业受益。
