Core Insights - A collaborative research team from Russia and China has identified a set of genes responsible for plant stress resistance, which could enhance potato yields under harsh conditions [1][2] - The study focuses on the cellular mechanisms of potato response to extreme growth conditions, particularly salt stress, rather than just external indicators like plant height and yield [1] - Understanding these molecular mechanisms could lead to the development of new stress-resistant potato varieties and microbial formulations to enhance resistance [1] Group 1 - The research addresses modern agricultural challenges such as soil salinization, rising temperatures, water scarcity, and soil degradation due to pesticides [1] - The team identified 29 genes related to endoplasmic reticulum stress response in the potato genome, analyzing their behavior in different plant tissues [1] - The research emphasizes the importance of cellular-level assessments to understand how individual cells respond to stress, including photosynthesis levels and enzymatic reaction rates [1] Group 2 - The team plans to focus on developing complex biological formulations that not only improve potato stress resistance but also protect against pathogens, thereby reducing pesticide use and promoting environmentally friendly crop production [2] - Scientists from both countries have jointly applied for funding from the Russia-China Science Foundation to support this project [2]
