^aExamples for leaves of abnormal shape include curled, flat, narrow, rolled, round, serrated, succulent, wilted, or wrinkled leaves, or leaves with a pointed apex or a short petiole.

^bExamples for chloroplasts of abnormal shape include amorphous, dumbbell-shaped, elongated, heterogeneously shaped, or wrinkled chloroplasts.

^cExamples for larger chloroplasts include larger or heterogeneously larger chloroplasts.

^dExamples for seed coat of abnormal surface include dull or shiny seed coat.

^eExamples for seeds of abnormal shape include aborted, elongated, round, or wrinkled seeds.

^fResults from leaf discs harvested at the beginning of the light period and 8 h after light period begins were combined.
