LeCDJ1, a chloroplast DnaJ protein, facilitates heat tolerance in transgenic …

The roles of a tomato (Lycopersicon esculentum) chloroplast‐targeted DnaJ protein (LeCDJ1) were investigated using wild‐type (WT) and sense transgenic tomatoes. The LeCDJ1 expression was upregulated by 38 °C, 42 °C, 45 °C,NaCl, PEG, methyl viologen (MV) and hydrogen peroxide (H2O2), but not by 30 °C and 35 °C. Meanwhile, LeCDJ1 was involved in the response of plants to abscisic acid (…
