Boron and blue light reduce responsiveness of Arabidopsis hypocotyls to exogenous auxins
Original language description
We reported earlier that boron stimulates hypocotyl growth in several Arabidopsis ecotypes but not in the boron-deficient mutant bor1-1. Others have shown that boron influences the metabolism and transport of the plant hormone auxin. We investigated howboron, in interaction with light, influences Arabidopsis hypocotyl growth responses to the exogenous auxins 1-NAA, 2,4-D and IAA. In either light condition, 1-NAA similarly inhibited hypocotyl growth in bor1-1 and the corresponding WT (Col-0), while in both genotypes, boron did not essentially affect the extent of the inhibition. Whatever the light conditions and in the absence of boron, 2,4-D inhibited hypocotyl elongation in WT, while in BL seedlings, high responsiveness to 2,4-D vanished when boron was added to the culture medium. Hypocotyl of bor1-1 seedlings in all boron concentrations tested and grown in the dark or RL responded to the auxin similar to WT plants. In BL, the mutant hypocotyls retained full sensitivity to 2,4-D at 0
