maize mutant phenotypes

crossbanded First two leaves of a homozygous cb*-N1620A mutant seedling (on left) showing diurnal crossbands of bleached light green tissue, and also first two leaves of a spt*-N1620B mutant (middle) with chlorotic spots. Note target spot distribution of spots (see Les1) . Dark spots on normal seedlings on right are the consequence of abnormal growth conditions in greenhouse

crossbanded Homozygous cb*-N1620A pale green mutant seedlings, showing white and green in crossbands and green leaf tips. These are indicators of sensativity of this mutant to environmental conditions at time of emergence.

crossbanded First three leaves of a cb*-N1962 mutant seedling showing white, pale green and green diurnal crossbands in repetitive sequence, demonstrating evening and morning transition zones of chlorophyll activity
