Gene Details:

• Gene ID: Solyc03g117590
• Gene Symbol: LeCDJ1
• Gene Name: DnaJ protein1
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• The roles of a tomato (Solanum lycopersicum) chloroplast-targeted DnaJ protein (LeCDJ1), whose expression was upregulated by treatment at 4 and 42 °C, and with high light, NaCl, polyethylene glycol, and H2O2, were investigated here using sense and antisense transgenic tomatoes.
• The expression of LeCDJ1 was induced by chilling stress. Overexpression of LeCDJ1 in tomato alleviated chilling stress-induced photoinhibition, whereas its suppression increased chilling sensitivity.
• Chloroplast heat-shock protein 70 was identified as the partner of LeCDJ1. These results indicate that LeCDJ1 has essential functions in maintaining PSII under chilling stress.
• Overexpression of LeCDJ1 increased heat tolerance by alleviating the photoinhibition of PSII and improving the activities of antioxidant enzymes in tomato chloroplast.
• LeCDJ1, a chloroplast DnaJ protein, facilitates heat tolerance in transgenic tomatoes.
• LeCDJ1 overexpression alleviates reactive oxygen species (ROS) accumulation under chilling stress.
