党旗在基层一线高高飘扬丨把科研的根扎进麦田里

Group 1 - The core issue of wheat stripe rust disease significantly impacts wheat production stability in China, with the research team at Northwest A&F University recovering over 5 billion kilograms of grain loss annually [1] - The research team has been investigating the transmission patterns of the disease since the 1950s, identifying seasonal movements of the pathogen that threaten food security across major wheat-producing regions [1] Group 2 - The research team has identified a shrub called Berberis as a key "intermediate host" for the mutation of the pathogen, leading to extensive field investigations across various high-altitude regions [2] - The team has collected over 4,000 samples of Berberis and identified more than 40 species, facing significant challenges in laboratory conditions due to the low germination rates of the seeds [2] Group 3 - After over ten years and thousands of experiments, the team has established a complete evidence chain confirming Berberis as the critical host for the pathogen's mutation, leading to the development of new control measures [3] - The innovative control measures have effectively reduced the mutation rate of the pathogen, showcasing the integration of personal growth and national needs within the research team's mission [3]
