FIGURE 1.

The chloroplast development of tsl2 mutant is sensitive to cold temperatures. (A) Temperature-sensitive phenotypes of the tsl2 mutant plants. Wild-type (WT) and tsl2 mutant seedlings grown under normal growth temperature (22°C) for 4 days were kept at 22°C or transferred to 16 or 29°C for 10 days and then photographed. (B) Analysis of chlorophyll contents of plant leaves grown under different temperature conditions. The data represents the average of samples and the error bars indicate the standard error (n = 3).
