研究工作

Research Focus

The central theme of our research is to unravel the molecular and biochemical regulatory mechanisms behind organelle-to-nucleus retrograde signaling, which is crucial for cellular homeostasis and adaptation to changing environmental conditions. We are particularly focused on how chloroplasts detect environmental fluctuations and relay signals to activate cellular stress responses. Our long-term goal is to decode the chloroplast-generated chemical signals that elicit specific stress responses to various environmental factors, ultimately aiming to enhance crop stress tolerance.

Main Achievements

As major research accomplishments, our team has identified that the oxidation of tryptophan residues in photosystem II reaction center proteins and specific ROS-sensing chloroplast proteins initiates retrograde signaling from chloroplasts to the nucleus, activating both stress and protective responses in plants (Wang et al., 2016, PNAS; Dogra et al., 2019, Nature Commun.; Dogra et al., 2022, Mol Plant; Lee, Kim. 2024, New Phytol).

Furthermore, we demonstrated that interactions between chloroplast ROS signaling and plant stress hormones—primarily salicylic acid and jasmonic acid—highlight the role of chloroplasts as complex environmental sensors that integrate multiple stress signals to drive adaptive responses (Li et al., 2020, Plant Cell; Fang et al., 2022, PNAS; Li et al., 2022, Plant Physiology; Lee et al., 2023, Plant Physiol.; Shi et al., 2024, Plant Commun.; Lee et al., 2024, Plant Cell).

We have also identified potential chloroplast thermosensor proteins that are essential for chloroplast biogenesis and thermal tolerance, particularly during germination. Our ongoing research explores these thermosensors further to elucidate chloroplast’s roles in managing temperature stress during the shift from heterotrophic to photoautotrophic growth.

We anticipate that our findings will greatly advance our understanding of chloroplast functions in stress responses, providing a robust foundation for enhancing plant resilience and boosting crop yields.
