Fine mapping of yellow-green leaf gene (ygl2) in soybean (Glycine max L.)

Leaf is the main organ of soybean photosynthetic carbon assimilation, and its color is related to light energy capture and transformation efficiency, and is also closely related to soybean yield. It is of great significance to analyze soybean yield by assimilation pathway. The yellow-green leaf is a...

Summary:Leaf is the main organ of soybean photosynthetic carbon assimilation, and its color is related to light energy capture and transformation efficiency, and is also closely related to soybean yield. It is of great significance to analyze soybean yield by assimilation pathway. The yellow-green leaf is a mutation type that is different from ordinary green leaves of soybean, and is an important genetic material for studying soybean leaf color-related genes. In this study, a yellow-green leaf mutant ygl2 (yel-low- green leaf 2), this mutant is naturally mutated from soybean line GL11, and its yellow-green leaf phenotype can be stably inherited. Compared with the green leaf wild-type GL11, the chlorophyll content in the leaves of the mutant ygl2 is extremely significantly reduced, the plant height, 100 There were significant differences in grain weight and protein content. Segregating populations were constructed using GL11 and ygl2. Genetic analysis showed that the yellow-green leaf phenotype of ygl2 was controlled
