Transcription Factor SiDi19-3 Enhances Salt Tolerance of Foxtail Millet and .

Salt stress is an important limiting factor of crop production. Foxtail millet ( L.) is an important model crop for studying tolerance to various abiotic stressors. Therefore, examining the response of foxtail millet to salt stress at the molecular level is critical. Herein, we discovered that SiDi19-3 interacts with SiPLATZ12 to control salt tolerance in transgenic and foxtail millet seedlings. overexpression increased the transcript levels of most Na/H antiporter (), salt overly sensitive (), and calcineurin B-like protein () genes and improved the salt tolerance of foxtail millet and . Six genes were isolated from foxtail millet. Compared with roots, stems, and leaves, panicles and seeds had higher transcript levels of genes. All of them responded to salt, alkaline, polyethylene glycol, and/or abscisic acid treatments with enhanced expression levels. These findings indicate that and other members regulate salt tolerance and other abiotic stress response in foxtail millet.
