aERD2 and aSAR1 of Arabidopsis are functional homologs of yeast genes
encoding proteins essential for endoplasmic reticulum (ER)-to-Golgi
transport. The regulation of these secretory pathway genes in yeast,
mammals, and plants is not known. High levels of expression of aERD2 and
aSAR1 were observed in roots, flowers, and inflorescence stems, with the
highest levels being detected in roots. The aSAR1 transcript levels were
highest in young leaves and declined during leaf maturation. Low levels of
aERD2 were detected in both young and fully mature leaves when compared
with roots. In situ hybridization showed that trichomes accumulate more
aERD2 transcript as the leaf expands, whereas aSAR1 is expressed equally in
all leaf cell types. Treating plants with tunicamycin, a drug that blocks
N-glycosylation in the ER, or with cold shock, known to block secretory
protein transport, led to a marked accumulation of aERD2 and aSAR1
transcripts. The Arabidopsis ARF gene, which encodes a GTPase probably
involved in Golgi vesicle traffic, was not affected by these treatments.
This study is an essential first step toward understanding the regulation
of genes that encode proteins involved in vesicular trafficking.
