The scutellum is part of the structure of a barley and rice [1] seed—the modified seed leaf. The scutellum (from the Latin scutella meaning "small shield") can also refer to the equivalence of a thin cotyledon in monocots (especially members of the grass family ).
The cotyledon of grasses and many other monocotyledons is a highly modified leaf composed of a scutellum and a coleoptile. The scutellum is a tissue within the seed that is specialized to absorb stored food from the adjacent endosperm. The coleoptile is a protective cap that covers the plumule (precursor to the stem and leaves of the plant).
Scutellum may refer to: Scutellum (insect anatomy), a term used in the anatomy of arthropods; Scutellum (botany), a term used in the morphology of grasses;
Megamelus scutellaris, the water hyacinth planthopper, is a true bug native to South America. It is used as a biological control agent to manage and reduce the spread of the water hyacinth (Pontederia crassipes, formerly Eichhornia crassipes), an invasive aquatic plant native to South America that has invaded many freshwater systems globally.
The model proposes that auxin, a plant growth hormone, is synthesized in the coleoptile tip, which senses light or gravity and will send the auxin down the appropriate side of the shoot. This causes asymmetric growth of one side of the plant. As a result, the plant shoot will begin to bend toward a light source or toward the surface. [3]
Scutellaria is a genus of flowering plants in the mint family, Lamiaceae.They are known commonly as skullcaps. [2] The generic name is derived from the Latin scutella, meaning "a small dish, tray or platter", [3] or "little dish", [4] referring to the shape of the calyx. [4]
Scutellarin is a flavone found in S. lateriflora and S. barbata. [12] It is transformed by hydrolysis into scutellarein. Genkwanin, hesperetin, quercetin, rutin, naringenin, chrysin, and daidzein are the flavonoids found in S. lateriflora. [12] The flavonoids are readily extracted using hot water. [13]
Scutelleridae is a family of true bugs.They are commonly known as jewel (stink) bugs or metallic shield bugs due to their often brilliant coloration. With the name based on the Asian genus Scutellera, they are also known as shield-backed bugs due to the enlargement of the thoracic scutellum into a continuous shield over the abdomen and wings. [1]
