* chl9 mutants exhibit a yellowish-green leaf phenotype under normal growth conditions (Fig. 1B). Abnormal leaf color is first observed on the leaves of 2- to 3-week-old seedlings. And the chl9 mutant exhibits its distinctive phenotype throughout development. In addition, the chl1 and chl9 mutants are viable. To characterize the chlorina phenotypes of chl9 mutants, the researchers first measured their total chlorophyll contents, and found them to be approximately 34% of wild-type Chl levels (Fig. 1D), indicating that the chlorina phenotype results from reduced chlorophyll levels.

  • chl9 mutants exhibit a yellowish-green leaf phenotype under normal growth conditions (Fig. 1B). Abnormal leaf color is first observed on the leaves of 2- to 3-week-old seedlings. And the chl9 mutant exhibits its distinctive phenotype throughout development. In addition, the chl1 and chl9 mutants are viable. To characterize the chlorina phenotypes of chl9 mutants, the researchers first measured their total chlorophyll contents, and found them to be approximately 34% of wild-type Chl levels (Fig. 1D), indicating that the chlorina phenotype results from reduced chlorophyll levels. Underdeveloped thylakoid membranes, poor granum structures and non-dispersed prolamellar bodies were observed in the chloroplasts of chl9 mutant leaves (Fig. 2C, F).
