Lesion mimic19 Lesion mimic: An immature Les19-2450/+ heterozygous mutant M1 origin plant, showing half-plant chimera of lesion and normal tissue, resulting from EMS-induced mutation in one DNA strand in the sperm nucleus of a single treated pollen grain. Necrotic lesions appeared first at tip of leaf and progress towards base

Lesion mimic19 Lesion mimic: Sectored mature leaf of the original Les19-N2450/+ heterozygous chimeric mutant plant, showing many small to medium-sized round or elliptical necrotic lesions which appeared first at the 4-leaf stage. Hich coalesce to cause general senescence. Which coalesce to cause general senescence
