英文摘要 | An arabidopsis mutant line named hy1- 101 was isolated because it shows stunted root growth on medium containing low concentrations of jasmonic acid ( ja). subsequent investigation indicated that even in the absence of ja, hy1- 101 plants exhibit shorter roots and express higher levels of a group of ja- inducible defense genes. here, we show that the hy1- 101 mutant has increased production of ja and its jasmonate- related phenotype is suppressed by the coil-1 mutation that interrupts ja signaling. gene cloning and genetic complementation analyses revealed that the hy1- 101 mutant contains a mutation in the hy1 gene, which encodes a heme oxygenase essential for phytochrome chromophore biosynthesis. these results support a hypothesis that phytochrome chromophore deficiency leads to overproduction of ja and activates coi1- dependent ja responses. indeed, we show that, like hy1- 101, independent alleles of the phytochrome chromophore- deficient mutants, including hy1- 100 and hy2 ( cs68), also show elevated ja levels and constant expression of ja- inducible defense genes. we further provide evidence showing that, on the other hand, ja inhibits the expression of a group of light- inducible and photosynthesis- related genes. together, these data imply that the ja- signaled defense pathway and phytochrome chromophore- mediated light signaling might have antagonistic effects on each other. |
