Gene Details:

• Gene ID:
• Gene Symbol: BjCdR15
• Gene Name: BZIP transcription factor15
• Genome:
• Species: Brassica juncea

Functional Descriptions:

• The Brassica juncea BjCdR15, an ortholog of Arabidopsis TGA3, is a regulator of cadmium uptake, transport and accumulation in shoots and confers cadmium tolerance in transgenic plants.
• BjCdR15 expression was detected mainly in the epidermis and vascular system of cadmium-treated plants, and increased in roots and leaves after cadmium treatment.
• The overexpression of BjCdR15 in Arabidopsis and tobacco enhanced cadmium tolerance: overexpressing plants showed high cadmium accumulation in shoots.
• BjCdR15/TGA3 regulated the synthesis of phytochelatin synthase and the expression of several metal transporters.
• The results indicate that BjCdR15/TGA3 transcription factors play a crucial role in the regulation of cadmium uptake by roots and in its long-distance root to shoot transport. BjCdR15/TGA3 may thus be considered as useful candidates for potential biotechnological applications in the phytoextraction of cadmium from polluted soils.
