“…Where secretion was not observed, SynGMs were retained in the ER and accumulated in fusiform bodies. According to Gunning (1998), fusiform bodies are dilated cisterna of the ER found only in Brassicaceae (Iversen et al, 1983) and in other members of the Capparales (Behnke and Eschlbeck, 1978). Glycosylation type, signal sequence type, and/or the protein (LeAGP1)], indicating that the secretory pathway (responsible for their final M r ) used for each glycopeptide in the different cell types is not equivalent in some cases.…”

Characterization of Synthetic Hydroxyproline-Rich Proteoglycans with Arabinogalactan Protein and Extensin Motifs in Arabidopsis

A series of gene constructs encoding synthetic glycomodule peptides with N-terminal signal sequences and C-terminal green fluorescent proteins were expressed in transgenic Arabidopsis (Arabidopsis thaliana) under the control of the 35S promoter. The synthetic glycomodule peptides were composed of repetitive proline-containing motifs that have been previously found to be substrates for prolyl hydroxylases and subsequent O-glycosylation of the hydroxyproline residues. All of the constructs were secreted in aerial tissues, but not in roots. The amount of hydroxylation and glycosylation of the various constructs varied depending on the tissue. Also, accumulation of the proteins exhibited a high degree of cell-type specificity within various tissues due to posttranscriptional effects. The observations reveal a high level of complexity in the synthesis, secretion, and turnover of the glycoproteins.

The variation in levels of major glucosinolates, myrosinase activity and the banding pattern of myrosinase isoenzymes has been investigated in three cultivars of English white cabbage. Differences were found both between cultivars and within cabbage heads. An attempt has been made to correlate these results with the differences in the distribution and structure of myrosin cells examined by light and electron microscopy. Myrosin cells were found to be similar in both distribution and structure in the three cultivars but to show variation within the cabbage heads.
