Accumulation of C-radiolabel in leaves and fruits after injection of [C]tryptophan into seeds of soybean.

abstract：:The unfolded protein response (UPR) is activated in plants in response to endoplasmic reticulum stress and plays an important role in mitigating stress damage. Multiple factors act in the UPR, including the membrane-associated transcription factor, BASIC LEUCINE ZIPPER 17 (bZIP17), and the membrane-associated RNA spli...
