A group of hypodermal cells are present at each corner of the young anther. The number of stamens comprised by the androecium is sometimes the same as the number of petals, but often the stamens are more numerous or fewer in number than the petals. Anthers typically contain four somatic cell layers encircling the sporogenous cells within each anther locule (Goldberg et al., 1993). Hypodermal definition: of the hypodermis | Meaning, pronunciation, translations and examples There are generally two pairs of spore-containing sacs … 2. a subcutaneous, injection; a syringe for making such an injection. These divide by periclinal walls to form inner primary sporogenous cells or archesporium and outer primary parietal cells. A very young anther is made up of homogeneous meristematic cells and more or less oblong in shape. Immediately after ecdysis, entry of water into the individual through the gills or gut causes inflation of the body that expands the new cuticle to its final size ( Capen, 1972 , Mykles, 1980 , Taylor and Kier, 2003 ). Anther wall : The mature anther wall consists of the following layers a. Epidermis b. Endothecium c. Middle layers d. Tapetum. 2. These cells act as sporangial initials. a. Epidermis: It is single layered and protective in function. The inner (L2) hypodermal cells divide periclinally to produce archesporial cells internally and primary parietal cells externally. Other articles where Anther is discussed: angiosperm: The androecium: …terminal saclike structures (microsporangia) called anthers. An epidermal layer of cells that secretes an overlying chitinous cuticle, as in arthropods. hypodermic: [ hi″po-der´mik ] 1. beneath the skin; injected into subcutaneous tissues. We took advantage of the jam-1::gfp marker ( Mohler et al., 1998 ), which localizes to the adherens junctions surrounding the seam cells. hypodermal wall cell layers are replaced by microsporocyte-like cells (Hord et al., 2006). Subsequent to the differentiation of parietal cells and sporogenous cells promoted by SPL/NZZ and BAM1/2, a number of genes are involved in the specialization of tapetal cells, including several leucine-rich repeat RLK genes, In each of the four lobes, some of the hypodermal cells begin to act as archesporial initials. 1. Parietal cells lie immediately below the epidermis. Of or relating to the hypodermis. The seam cells are lateral hypodermal blast cells that donate daughter nuclei to the hypodermal syncytium after each cell division, and eventually fuse in adults (Sulston and Horvitz, 1977). derm n. 1. Gradually the anther becomes a four-lobed structure, in each lobe hypodermal cells become differentiated by their shape and dense contents with distinct nucleus, these cells are called archespon'um or archesporial cells. b. In maize anther primordia, the outer (L1) layer produces the epidermis . hypodermal: (hī′pə-dûr′məl) adj. The hypodermal cells then secrete a soft and pliant new cuticle, extending new microvilli into it as it is constructed. (2) Development of anther and formation of microspores (Pollen grains) : The young anther consists of homogenous mass of paranchymatous cells surrounded by epidermis. It soon becomes four lobed. The cells undergo repeated anticlinal divisions to cope up with the rapidly enlarging internal tissues. Lying below the epidermis.
