Five cDNA clones coding for glycine-rich proteins in Arabidopsis thaliana
were isolated. The corresponding genes are present in the genome as single
copies. The derived protein sequences contain highly repetitive
glycine-rich motifs. There is, however, little homology among them, nor
with previously described glycine-rich proteins from other species. All
five genes are expressed in leaves and stems of 6-week-old plants but show
different patterns of expression in other organ systems. Analysis of the
effect of different external stimuli on the expression pattern showed that,
in most cases, the transcript levels were moderately but selectively
affected. With flooding stress, the accumulated level of the transcript
from one of the genes was remarkably increased.
