Development and Pollination Regulated Accumulation and Glycosylation of a Stylar Transmitting Tissue-Specific Proline-Rich Protein.
The extracellular matrix of stylar transmitting tissues of many angiosperms is enriched in secretory materials that are believed to be important for interactions with pollen tubes. We have previously characterized two related cDNAs (TTS-1 and TTS-2) for stylar transmitting tissue-specific proline-rich proteins (TTS proteins) from Nicotiana tabacum. We show here that TTS proteins are highly glyc...
متن کاملStylar Transmitting Tissue of Transgenic Tobacco
Tobacco was transformed with a gene coding for an S-locus-specific glycoprotein of Brassica oleracea. The resulting transgenic plants showed tissue-specific and developmentally regulated expression of the introduced gene. lmmunolocaliration experiments showed that the Brassica gene was expressed in the stylar transmitting tissue of the transgenic plants. The pattern of expression of the introdu...
متن کاملA lily stylar pectin is necessary for pollen tube adhesion to an in vitro stylar matrix.
Pollen tube cells adhere to the wall surface of the stylar transmitting tract epidermis in lily. This adhesion has been proposed as essential for the proper delivery of the sperm cells to the ovule. An in vitro adhesion bioassay has been used to isolate two stylar molecules required for lily pollen tube adhesion. The first molecule was determined to be a small, cysteine-rich protein with some s...
متن کاملA lipid transfer-like protein is necessary for lily pollen tube adhesion to an in vitro stylar matrix.
Flowering plants possess specialized extracellular matrices in the female organs of the flower that support pollen tube growth and sperm cell transfer along the transmitting tract of the gynoecium. Transport of the pollen tube cell and the sperm cells involves a cell adhesion and migration event in species such as lily that possess a transmitting tract epidermis in the stigma, style, and ovary....
متن کاملThe Histological Evidences for Developmental Alternations in the Transmitting Time of Impulses along the Thalamocortical Tract
Change in transmitting time of impulses along axons is traditionally attributed to two parameters: the myelin formation and the diameter of neurite, both rising during the postnatal development. In the previous study, we showed that conduction velocity of the fibers projecting from the thalamus to the layer IV of the somatosensory (barrel) cortex increases as a function of age. However, the con...
