Global Phosphorus Metabolism Crisis, Food Crisis Response to Climate Change, Development of High Phosphorus-Use-Efficiency Crops, and Breeding Utilizing Key Genes Related to Phosphorus-Use-Efficiency.

To address this, we will conduct research focusing on the following:

1. Characterization and Utilization of Novel Pup1 Key Genes

We will study OsPupK29-2, a key gene within the major Phosphorus-Use-Efficiency (PUE) locus Pup1, whose structure and function have not yet been fully elucidated.

2. Functional and Network Analysis of Meta-QTL Key Genes

This involves the functional analysis of key genes associated with PUE meta-QTLs, as well as gene network analysis and molecular marker development for breeding applications.

3. Pup1-mediated Abiotic Stress Resistance

We will investigate the mechanism of heat tolerance in Pup1 introgression lines during the seedling and grain-filling stages. We will also identify antagonistic genes that emerge when combined with the submergence-tolerant gene Sub1, and develop new lines with improved tolerance to multiple climate change-related stresses.
