(n.) A transparent, extensible membrane of extreme tenuity, which forms the innermost coating of grains of pollen.
Example Sentences:
(1) The central body is therefore surrounded by three layers, the intine, the exine, and the capsule, all containing acid mucopolysaccharide.
(2) These quantitative studies confirm the gametophytic and sporophytic origins of the intine and exine proteins.
(3) A particularly prominent zone, triangular in profile, is left where the wall joins with the intine.
(4) The wall residues persist throughout the maturation phase of the pollen and are considered to be either callose resulting from incomplete digestion of the initial wall, or some other polysaccharide material which is unevenly laid down along the wall and concentrated at the junction with the intine.
(5) Vesicles that appear to originate from the contracting cell membrane of the central body may account for the lipid content of the intine.
(6) All recurrent atheromas developed more than 2 years following original operation (mean, 5 years) and intinal fibrosis was seen in the first postoperative year in all but one patient (mean, 9 months).
(7) The intine fibrils form a network in the gel-like homogeneous matrix of the CC2 layer.
(8) A striking difference was also seen in the preservation of inclusions in the intine.
(9) The presence of intine vesicles in the encysting organism was confirmed in frozen-etched cells.
(10) Wall material may be represented merely as short stubs projecting out from the intine into the cytoplasm, in which event the 2 nuclei lie close to each other and are separated by only a narrow zone of cytoplasm.
(11) The exines contained mostly bound lipid, but intines contained primarily free lipid.
(12) The intine part and the germination pores were almost completely unlabelled.
(13) The microspores of Marsilea and Pilularia have non-specific esterase activity concentrated in the intine inthe immediate vicinity of the germinal site; that is, above the position of the future male gametangia.
(14) The incomplete wall always makes contact with the intine on the intine-side of the spindle.
(15) In situ hybridization mappings indicate that the mouse AMBP gene (Intin-4) is located at 4C1----C4, and the H1 (Intin-1) and H3 (Intin-3) genes are colocated at 14A2----C1.
(16) The endogenous cysts are depleted in polybeta-hydroxybutyrate and have a narrower intine but show an increased resistance to desiccation and are susceptible to lysis by chelating agents.
(17) Varied forms and sizes of intine inclusions were evident in FS pollen but these were not discernible in the CF image.
(18) Cultured in vitro, the pollen showed erratic germination, with a scatter of germination times up to 24 h. This was associated with variation between individual grains in the rate of hydration and dispersal of the pectins of the oncus, the thickened outer component of the intine present at each aperture.
(19) Samples taken at intervals and examined by electron microscopy revealed that as germination progressed, vesicle-like and fibrillar structures became visible in the intine region.
(20) Examination of large numbers of cells and cysts by these methods revealed four structural details not reported previously: intine fibrils, intine vesicles, intine membrane, and microtubules.
