Lesion mimic3 Eighth leaf of Les3-A781 homozygous mutant plant showing various sizes of necrotic lesions (extreme expression) (photo courtesy D. Hoisington)


Lesion mimic4 Section of a Les4-N1375/+, mutant, 8th leaf, showing many small necrotic lesions with white centers, some in clusters.


Lesion mimic4 Mid section of A Les4-N1375/+ mutant plant at flowering, in M14/W23 background, showing striking dark brown lesions on leaf sheath but not on ear. Lesions first appear just before flowering, enlarge and spread rapidly over whole plant in a few days causing quick plant senescence.


Lesion mimic5 Cross-section of a mature 8th leaf from a Les5-N1449/+ mutant plant, showing many small chlorotic spots, some of which have bleached to white


Lesion mimic6 Two Leaf sections of a Les6-1451/+ mutant plant in a Mo20W background, immature (top) and mature (bottom) 8th leaf, in Mo20W background, showing developmental sequence of lesion formation in this mutant.


Lesion mimic7 Lesion mimic: Section of the 8th leaf of a Les7-N1461/+ heterozygous mutant plant showing many small round chlorotic lesions.


Lesion mimic8 Lesion mimic: Section of 8th leaf of homozygous Les8-N2005 mutant plant, showing many distinct necrotic lesions. Compare with heterozygote.


Lesion mimic9 Section of the eighth leaf of a Les9-N2008/+ heterozygous mutant plant, M14/W23 background, showing profuse tiny lighter green pre-lesion spots.


Lesion mimic10 Lesion mimic; genetic modifiers: 8th leaf of two Les10-A607/+ heterozygous mutant plants, showing , on left, typical expression in M14/W23 outcross and, right, strikingly fewer lesions, better color and stronger growth in Mo20W outcross.
