OsMYB103 is essential for tapetum degradation in rice
Theoretical and Applied Genetics, 2022OsMYB103 positively regulates tapetum degradation, and functions downstream of TDR and upstream of EAT1 and PTC1. The precise regulation of programmed cell death (PCD) of the tapetum is crucial for the development of anthers and pollen in rice. In this study, we isolated and identified a male-sterile mutant of rice, osmyb103, which exhibited delayed ...

The Botanical Review, 1978
Commonly found in sympetalous plants with unitegmic and tenuinucellate ovules, the integumentary tapetum exhibits great diversity in its distribution, morphology, cytology, differentiation, and behaviour. It is separated from the nucellus and embryo sac by layers of cuticle.

1982
The tapetum lucidum is a multi-layer reflecting surface situated in the eyes of a number of vertebrates (Fig. 1). It is located behind the photoreceptors and gives them a second opportunity to absorb light not initially absorbed (see 15 for review). Our interest in the physiological role of taurine and recent discovery that dietary taurine deprivation ...

THE MORPHOLOGY OF THE CAT TAPETUM LUCIDUM
American journal of optometry and physiological optic, 1980Abstract Tapetum lucidum is a comparatively neglected structure found in many species used in vision research. Fundus photography and light and electron microscopy were used in this study to provide more information about the macro‐and microstructure of this reflectant layer.

The structure of the tapetum of the eye of the sheep
Cell and Tissue Research, 1975The structure of the tapetum of the sheep's eye has been examined by transmission electron microscopy. It consists of regularly arranged layers of collagen fibrils, estimated from the hydroxyproline content to make up about 60 percent of the dry weight of the tissue.

The tapetum and systematics in monocotyledons
The Botanical Review, 1998This paper critically reviews the homologies and distribution of tapetum types in monocotyledons, in relation to their systematics. Two main types of tapetum are widely recognised: secretory and plasmodial, although intermediate types occur, such as the “invasive” tapetum described inCanna.

The Journal of the Acoustical Society of America, 2006
Many mammals including dogs, cats, deer, and dolphins, but not humans, have a reflective membrane at the back of the eye. This tapetum lucidum affords the light-sensitive retinal cells a second chance for photon-photoreceptor stimulation, enhancing low light visual sensitivity.

Tapetum character states: analytical keys for tapetum types and activities
Canadian Journal of Botany, 1997The different types of tapetum found in the spermatophyta are described, along with associated characters. The characters (taken singly, pairwise, or in multiple combinations) are (i) tapetum types; (ii) cell walls, tapetum types, and loculus; (iii) tapetal cells individually, tapetum types, and loculus; (iv) number of pollen grains enveloped by ...

Ultrastructural Observations on the Tapetum lucidum fibrosum
Anatomia, Histologia, Embryologia, 1979AbstractThe ultrastructural comparison made between the tapetum cellulosum of the cat and the tapetum fibrosum of the sheep has shown that the rods and the collagen fibrils have the same diameters and the same spatial arrangement.

Tapetum lucidum in the pigmented and albino ferret
Experimental Eye Research, 1984Light and electron microscopy showed that the tapetum lucidum in the pigmented ferret is morphologically indistinguishable from that in the albino ferret. The matrix of the rods of the tapetal cells was strongly osmiophilic, but glutaraldehyde fixation before osmium tetroxide treatment caused a dissolution of the matrix material.
