DEGs related to the photosynthesis pathways. A The KEGG pathway map of photosynthesis. B The KEGG pathway map of photosynthesis-antenna protein. The images were obtained from the KEGG database. The DEGs expression pattern was used to annotate and generate a corresponding map. The green box with gene symbols denotes down-regulated expression in the chlorosis group, while the red box denotes up-regulated expression. The genes without significant change were displayed with a grey box. C Expression profile of genes related to photosynthesis pathways. The vertical column represents a sample. The horizontal row represents a gene. The expression ratios are based on log2 RPKM value and normalized at row level. Each gene is presented with gene ID and gene name. PsbA-Psb27, photosystem II structure proteins; PsaA-PsaX, photosystem I structure proteins; PetB-PetG, cytochrome b6/f complex proteins; PetF, ferredoxin; beta, fF-type H+/Na + −transporting ATPase subunit beta; a, F-type H + -transporting ATPase subunit a; Lhca1-Lhca5, light-harvesting complex I chlorophyll a/b binding protein; Lhcb1-Lhcb7, light-harvesting complex II chlorophyll a/b binding protein 1
