1.14.13.81 | A96T | site-directed mutagenesis, the point mutation in OsCRD1 does not change its location, but leads to deficiency in chlorophyll biosynthesis and chloroplast development and decreases photosynthetic capacity in rice, phenotype | Oryza sativa Japonica Group |
1.14.13.81 | G286A | naturally occurring mutation, the mutation in enzyme MPEC causes the phenotype of the rice pale-green leaf mutant m167, phenotype | Oryza sativa Japonica Group |
1.14.13.81 | additional information | mutant m167 is isolated from a EMS mutagenized population from the Japonica rice variety Kitaake. To construct the F2 mapping population, the yellow-green leaf rice mutant m167 is crossed with rice varieties Zhefu802 and Dular, respectively, genotyping of F2 population | Oryza sativa Japonica Group |

1.14.13.81 | malfunction | mutation of in enzyme MPEC causes the pale-green leaf mutant phenotype of mutant m167 with yellow-green leaves across the whole lifespan. Chlorophyll content decreases by 43-51% and the granal stacks of chloroplasts becomes thinner in m167. Chlorophyll fluorescence parameters, including Fv/Fm (the maximum quantum efficiency of PSII) and quantum yield of PSII (Y(II)), are lower in m167 than those in wild-type plants, and photosynthesis rate decreases by 40% in leaves of m167 mutant compared with wild-type plants, which leads to yield reduction in m167 | Oryza sativa Japonica Group |
