Developmentally regulated expression of soybean proline-rich cell wall protein genes.
Previously, we reported the characterization of a developmentally regulated proline-rich cell wall protein (SbPRP1) gene of soybean; the encoded protein is represented by a consensus amino acid repeat structure of Pro-Pro-Val-Tyr-Lys [Hong, J.C., Nagao, R.T., and Key, J.L. (1987). J. Biol. Chem. 262, 8367-8376]. Two other closely related members of this family of proline-rich protein (PRP) gene...
متن کاملPatterns of soybean proline-rich protein gene expression.
The expression patterns of three members of a gene family that encodes proline-rich proteins in soybean (SbPRPs) were examined using in situ hybridization experiments. In most instances, the expression of SbPRP genes was intense in a limited number of cell types of a particular organ. SbPRP1 RNA was localized in several cell types of soybean hypocotyls, including cells within the phloem and xyl...
متن کاملCharacterization of a Proline-rich Cell Wall Protein Gene Family of Soybean
Further characterization of a proline-rich cell wall protein gene family from soybean (Glycine max (L.) Merr) has been accomplished by the isolation and sequence analysis of two additional genes, SbPRP2 and SbPRP3, which encode mRNAs of 1050 and 650 nucleotides in length, respectively. Like the proline-rich protein gene, SbPRPl, which was previously reported (Hong, J. C., Nagao, R. T., and Key,...
متن کاملCharacterization and sequence analysis of a developmentally regulated putative cell wall protein gene isolated from soybean.
A cDNA clone, pTU04, which hybridizes to two different sizes of mRNA on Northern blots was isolated from soybean suspension culture cell poly(A) RNA. Northern analysis reveals that meristematic tissue produces a 1050-nucleotide mRNA while quiescent mature cells produce primarily a 1220-nucleotide mRNA homologous to pTU04. The cDNA and its corresponding genomic clone have been partially characte...
متن کاملA developmentally regulated hydroxyproline-rich glycoprotein from the cell walls of soybean seed coats.
In soybean seeds the level of hydroxyproline is regulated in a developmental and tissue-specific manner. The seed coat contains approximately 77% of the total hydroxyproline in the seed at all stages of development. We determined the ratio of hydroxyproline to dry weight in a number of tissues within the seed; however, only the seed coat shows an increase in this ratio during development. Withi...
