“…In contrast, after callogenesis induction, zmHRGP is expressed in those cells ¢rst di¡er-entiating to callus in the embryo nodular region. In this case the correlation of zmHRGP and H4 expression is lost in the scutellum, as has been described after wounding [5]. Our results indicate that the factors controlling the expression of genes coding for proline-rich proteins in the embryo are affected within 24 h of culturing in conditions that alter the developmental programme of the embryo.…”

“…zmHyPRP expression is arrested when the maturation stage is reached, after ABA induction [4]. zmHRGP codes for a cell wall protein accumulated in tissues rich in dividing cells [5]. During embryo development zmHRGP expression is restricted to the morphogenetic stage and is absent from the scutellum [6,7] being a marker of suspensor and vascular tissue development [2,3].…”

The pattern of expression of two genes coding for proline-rich proteins, zmHyPRP and zmHRGP, in Zea mays is modified when the embryogenesis programme is altered by placing the embryos in conditions which promote either precocious germination or callogenesis. zmHyPRP gene expression is rapidly arrested when the embryogenesis programme is altered. zmHRGP mRNA is highly induced in scutellum within a few hours of callogenesis or precocious germination.z 1998 Federation of European Biochemical Societies.

“…They do have a threoninerich protein with sequences reminiscent of the typical extensin structure (Kieliszewski et al, 1990), and as with extensin, the soluble precursors accumulate early in the cell cycle and become insoluble during cell elongation and differentiation (Ludevid et a/., 1990). This polymer is enriched in vascular tissue and in special, reinforced wall structures such as the pericarp (Hood etal., 1988(Hood etal., , 1991.…”

Structural models of primary cell walls in flowering plants: consistency of molecular structure with the physical properties of the walls during growth

SummaryAdvances in determination of polymer structure and in preservation of structure for electron microscopy provide the best view to date of how polysaccharides and structural proteins are organized into plant cell walls. The walls that form and partition dividing cells are modified chemically and structurally from the walls expanding to provide a cell with its functional form. In grasses, the chemical structure of the wall differs from that of all other flowering plant species that have been examined. Nevertheless, both types of wall must conform to the same physical laws. Cell expansion occurs via strictly regulated reorientation of each of the wall's components that first permits the wall to stretch in specific directions and then lock into final shape. This review integrates information on the chemical structure of individual polymers with data obtained from new techniques used to probe the arrangement of the polymers within the walls of individual cells. We provide structural models of two distinct types of walls in flowering plants consistent with the physical properties of the wall and its components.

“…We previously described the isolation of a cDNA encoding a maize HRGP and showed that the corresponding mRNA is enriched in tissues with mitotic activity (Stiefel et al, 1988) and in wounded tissues (Ludevid et al, 1990). The extensins, a group of HRGP proteins that have been found in differentiating and wounded tissues of several dicot species (Showalter and Varner, 1989), are encoded by small gene families.…”
