|a Photosynthesis, as an important biological process of plants, produces organic substances for plant growth and development. Although the molecular mechanisms of photosynthesis had been well investigated, the relationship between chlorophyll synthesis and photosynthesis remains largely unknown. The leaf-color mutant was an ideal material for studying photosynthesis and chlorophyll synthesis, which had been seldom investigated in tomato. Here, we obtained a yellow leaf tomato mutant ym (The mutant plants from the line of zs4) in field. Transmission electron microscopy (TEM) and photosynthetic parameters results demonstrated that chloroplast's structure was obviously destroyed and photosynthetic capacity gets weak. The mutant was hybridized with the control to construct the F2 segregation population for sequencing. Slym1 gene, controlling yellow mutant trait, was identified using Bulked Segregation Analysis. Slym1 was up-regulated in the mutant and Slym1 was located in the nucleus. The genes associated with photosynthesis and chlorophyll synthesis were down-regulated in Slym1-OE transgenic tomato plants. The results suggested that Slym1 negatively regulate photosynthesis. Photosynthetic pigment synthesis related genes HEMA, HEMB1, CHLG and CAO were up-regulated in Slym1 silencing plants. The redundant Slym1 binding the intermediate proteins MP resulting in hindering the interaction between MP and HY5 due to the Slym1 with a high expression level in ym mutant, lead to lots of the HY5 with unbound state accumulates in cells, that could accelerate the decomposition of chlorophyll. Therefore, the yellow leaf-color mutant ym could be used as an ideal material for further exploring the relationship between leaf color mutant and photosynthesis and the specific mechanism
