physiological function	in an isoform Igl deficient background, mutant plants deficient in chloroplastic isoform Bx1 allow better development of the cereal aphid Rhopalosiphum padi, and are affected in penetration resistance against the fungus Setosphaeria turtica. At stages preceding major tissue disruption, Rhopalosiphum padi and Setosphaeria turtica elicited increased accumulation of 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one-glucoside, 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one, and 2-hydroxy-4,7-dimethoxy-1,4-benzoxazin-3-one-glucoside (HDMBOA-glc), which is most pronounced in apoplastic leaf extracts. Chloroplastic isoform-deficient bx1 mutant lines deposite less chitosan-induced callose than Bx1 wild-type lines, whereas apoplast infiltration with 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one, but not HDMBOA-glc, mimicks chitosan-induced callose	Zea mays
