What's the difference between apothecium and scutellum?
Apothecium
Definition:
(n.) The ascigerous fructification of lichens, forming masses of various shapes.
Example Sentences:
Scutellum
Definition:
(n.) A rounded apothecium having an elevated rim formed of the proper thallus, the fructification of certain lichens.
(n.) The third of the four pieces forming the upper part of a thoracic segment of an insect. It follows the scutum, and is followed by the small postscutellum; a scutella. See Thorax.
(n.) One of the transverse scales on the tarsi and toes of birds; a scutella.
Example Sentences:
(1) 3. beta-Sitosteryl linoleate is the major sterol ester of the scutellum and endosperm.
(2) The scutellum of maize is a fully differentiated, nondividing, diploid embryonic tissue.
(3) To our knowledge, this is the first observation of a gradient-type spatial pattern of a eukaryote gene activation occurring in a stable, virtually nondividing tissue such as the maize scutellum.
(4) The gene for isoenzyme I is expressed in the aleurone, scutellum and prominently in young leaves.
(5) A gene (Adhr(r)) which controls the activity of alcohol dehydrogenase in the scutellum of maize has been found.
(6) Immunofluorescent microscopy demonstrates that L3 protein accumulation is tissue-specific, confined to the embryo (scutellum and embryonic axis) and the aleurone layer of developing seed.
(7) In the scutellum of maize kernel after imbibition, lipase activity increased rapidly, concomitant with the decrease in storage triacylglycerols.
(8) In contrast, the gene for isoenzyme EI is transcribed at relatively high levels in young leaves, but also in the scutellum and aleurone of germinated grain.
(9) In situ RNA hybridization in isolated germinating embryo sections demonstrates that the PRms gene is expressed in the scutellum, particularly in a group of inner cells, and in the epithelium lying at the interface of the scutellum and the endosperm.
(10) The HRGP mRNA accumulates in the embryo axis and not in the scutellum and preferentially in dividing and provascular cells.
(11) This marker is R-scm3, which conditions anthocyanin pigment in the aleurone of the endosperm and the scutellum of the embryo.
(12) The scutellum and endosperm together contain 80% of the sterol ester of the seedling.
(13) Enzyme activity in Adh1-3F1124 sporophytic organs (scutellum and roots) is greatly reduced, while activity levels remain normal in the male gametophyte (pollen).
(14) Rates of catalase synthesis and degradation were measured in the scutellum of the germinating maize seedling by the technique of Price, Sterling, Tarantola, Hartley & Rechcigl [J. Biol.
(15) Drones with pollinia on their scutellum visit other orchids, which facilitates pollination.
(16) On germination, there is a transient re-appearance of mRNA to pZE40, with accumulation specifically restricted to the scutellum of the seedling.
(17) The composition of the sterol ester fraction of the shoot, root, scutellum and endosperm of 10-day-old maize seedlings was investigated.
(18) Northern-blot analyses with gene-specific probes indicate that the (1-->3)-beta-glucanase isoenzyme GIII mRNA accumulates in developing leaves; no mRNA transcripts were detected in the aleurone or scutellum of germinated grain, or in mature vegetative tissues.
(19) Histochemical analysis of transgenic plants and their progeny showed that the maize Adh1 promoter is constitutively expressed in root caps, anthers, anther filaments, pollen, scutellum, endosperm and shoot and root meristem of the embryo.
(20) In situ hybridization showed localization of the 1.1-kilobase rice lectin mRNA in root caps and specific cell layers of the radicle, coleorhiza, scutellum, and coleoptile.
