Table 3 The function of candidate genes related to the accumulation of cadmium in rice

Chromosome Gene Function Object 2 LOC_Os02g50240 It participates in the regulation of various biological processes and stress response Cytoplasmic glutamine synthetase 2 LOC_Os02g52780 It regulates ABA-dependent stress-related gene expression to enhance the plant tolerance of drought and salt Transcription factors bZIP 9 LOC_Os09g31200 A major determinant of plant response to stress Zinc finger protein 9 LOC_Os09g35030 It specifically combines with drought response elements and controls many stress-induced genes Transcription factors AP2/EREBP 9 LOC_Os09g37949 It plays an important role in salt stress response Receptor protein kinase
