Starch content in leaves of 4‐, 6‐, and 8‐week‐old wild‐type (WT) and mutant Arabidopsis plants. Plants were grown under a 12/12 hr‐light/dark photoperiod, harvested at the end of the night period and stained with iodine. (a) WT and single BAM mutants. (b) WT and quadruple mutants lacking all but one BAM gene, and B‐Null lacking all five BAM genes. For each treatment, 3–5 leaves from at least two different plants were analyzed and representative leaves are shown
