The polyamine spermine induces the unfolded protein response via the MAPK cascade in Arabidopsis

open access: yesFrontiers in Plant Science, 2015
In Arabidopsis three basic region leucine zipper (bZIP) transcription factor genes, bZIP17, bZIP28 and bZIP60, play crucial roles in the unfolded protein response (UPR). Previously we found that bZIP60 is one of the spermine-induces genes.

Structural and stereogenic properties of spiro- and ansa-substituted 1,3-propanedioxy derivatives of a spermine-bridged cyclotriphosphazene [PDF]

open access: yes, 2006
Reaction of 1,3-propanediol with the achiral spermine-bridged cyclophosphazene 1 at various molar ratios in THF gives a number of spiro-and ansa-derivatives that exhibit different stereogenic properties, viz. racemic, meso or achiral forms. As expected,
