maize mutant phenotypes

crossbanded Homozygous cb*-N1620A pale green mutant seedlings, showing white and green in crossbands and green leaf tips. These are indicators of 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

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
