Evidence for autocatalytic cross-linking of hydroxyproline-rich glycoproteins during extracellular matrix assembly in Volvox.
The alga Volvox carteri is one of the simplest multicellular organisms, yet it has a surprisingly complex extracellular matrix (ECM), making Volvox suitable as a model system in which to study ECM self-assembly. Here, we analyze the primary structures and post-translational modifications of two main ECM components synthesized in response to sexual induction as well as wounding. These proteins a...
متن کاملThe cell wall hydroxyproline-rich glycoprotein RSH is essential for normal embryo development in Arabidopsis.
Although a large number of embryo mutants have been studied, mostly at the morphological level, the critical molecular and cellular events responsible for embryogenesis are unknown. Here, we report that using an enhancer-trap embryo mutant of Arabidopsis, we identified a gene, ROOT-SHOOT-HYPOCOTYL-DEFECTIVE (RSH), that is essential for the correct positioning of the cell plate during cytokinesi...
متن کاملExpression of a Soybean Hydroxyproline-Rich Glycoprotein Gene Is Correlated with Maturation of Roots
A novel extensin gene has been identified in soybean (Glycine max L.) that encodes a hydroxyproline-rich glycoprotein (SbHRGP3) with two different domains. In this study expression of SbHRGP3 was investigated during soybean root development. SbHRGP was expressed in roots of mature plants, as well as seedlings, and showed a distinct pattern of expression during root development. The expression o...
متن کاملA developmentally regulated hydroxyproline-rich glycoprotein in maize pericarp cell walls.
We have studied the accumulation of peptidyl hydroxyproline in the pericarp of developing maize (Zea mays L., Golden cross Bantam sweet corn) kernels. Although this hydroxyproline accumulates throughout development, it is most soluble and its content per milligram dry weight greatest at midmaturation stages of development. Salt-soluble proteins containing this hydroxyproline from isolated cell ...
متن کاملA wound-inducible member of the hydroxyproline-rich glycoprotein gene family in sunflower.
HRGPs4 are a diverse family of cell wall proteins including extensins, hydroxyproline-rich lectins of the Solanaceae, and arabinogalactans (7, 8). HRGPs can comprise as much as 15% of the cell wall dry weight. Pathogen-induced accumulation ofextensin-like HRGPs and the correlation ofincreased cell wall HRGP with increased pathogen resistance are documented (3, 4). The precise function of HRGPs ...
