... defects in the shoot meristem, FAF over- expression resulted in an arrested root meristem. This finding suggests that the FAF proteins can influence meristem maintenance at both poles of the growing plant. ... STIP in main- taining cell di vision. This suggests that STIP and the FAFs might have opposing functions in integrating sugar signalling into the meristem...

... in the dark to examine how the mutations affected phenanthrene- induced growth responses in seedlings. The mutants included the ethylene overproducer eto3 [32]; the ethyl- ene-insensitive gain-of-function ... in the PAH-induced stress response in Arabidopsis. At the transcriptional level, the results identify specific gene targets that will be valuable in finding le...

... corresponding to Tyr207 in the human GLTP is a lysine in both AtGLTP1 (Lys200) and At3g21260, but an arginine in At1g21360. This makes the sugar- binding pocket of At1g21360 very rich in arginines. Fourthly, ... arginines. Fourthly, the residue corresponding to Val209 in human GLTP corresponds to Ser202 in AtGLTP1, a methionine in At1g21360 and a proline in At3g21260 (Fi...
