Connexin-32 and Connexin-43 Immunoreactivity in Rodent Taste Buds
… and connexin–43–LIR in rodent taste buds through immunocytochemical analysis and DAB (Di–amino–benzidine) immunoelectron microscopy. We observed that connexin–32–LIR co–localizes with P2X2–LIR in nerve fibers and in a small subset of NCAM–LIR cells. Connexin–32–LIR does not …

The Physiological Role of Serotonergic Transmission in Adult Rat Taste Buds
… and that of the many serotonin receptors, taste buds express only the 5-HT1A and 5-HT3 subtypes. The 5-HT1A subtype was found to be expressed in TRCs, while the 5-HT3 subtype is presumed to be expressed in postsynaptic neural elements. Further, 5-HT and the 5-HT1A receptor have been shown to …

Studies on the factors influencing inhibition of lateral buds and branches
… relative importance in the outgrowth of lateral buds. Both nitrogen and light are shown to be major factors in tillering of ryegrass and in addition that high nitrogen levels alone induce tillering in an apparently specific manner. This is in contrast to corresponding light treatments where such …

Dopamine-Beta-Hydroxylase and Norepinephrine Transporter Immunoreactivity in Rat Taste Buds
<p>Of the handful of neurotransmitters modulating taste response, norepinephrine (NE) may be the least understood. Although the physiological role of NE has been tested, it is still unclear whether the rat taste bud may serve as an endogenous source of neurotransmitter or if it must be taken up …

Estimating Heat Tolerance of Tree Buds in the Southeastern United States
… studies have been conducted to determine if tree buds may exhibit speciesspecific fire or heat tolerance. Understanding potential relationships between bud characteristics and fire tolerance may assist prescribed fire managers as they target control of specific undesired tree species while …

Resource partitioning in buds and insect induced galls in the biocontrol of Acacia pycnantha
… project was to determine whether the galls and buds of Acacia pycnantha have significantly different energy values, and to determine what affect this has on the plant. There was no significant difference between gall and bud energy values (p=0.029, df-=7, alpha=0.05) but gall energy values were, …

Mosaic Analysis with Double Markers (MADM) as a Method to Map Cell Fates in Adult Mouse Taste Buds.
<p>Taste buds are chemosensory endorgans embedded in the oral epithelium composed of cells that undergo continuous replacement. Mature taste cells live on average 10-14 days and are replaced by new cells when they die. However, the mechanism by which taste cells are produced and integrated into the …

Effect of chilling, hydrogen cyanamide, hot water and bud scale removal on bud break of 'Tifblue' rabbiteye blueberry
… scales on bud break of floral and vegetative buds of 'Tifblue' rabbiteye blueberry (Vaccinium ashei Reade). Hydrogen cyanamide was effective in promoting floral bud break of 'Tifblue' only on whole plants, at chilling exposures between 300 to 500 hours. However, vegetative bud break was …

A survey of the food habits of the gray squirrel (Sciurus carolinensis) in Montgomery County, Virginia
… with a red oak-black walnut mixture (7%), elm buds and flowers (10%), and corn (9%). As a group, however, flowers composed 28% of the spring diet. Summer foods consisted primarily of herbaceous plants (24%), herbaceous buds (13%), hickory nuts (13%), and woody buds (10%). Of the aforementioned …

In vitro micropropagation, evaluation of disease resistance and hardiness of several new rose cultivars
… in vitro. Stem pieces containing axillary buds, leaves and roots of these cultivars were the source of explants. Shoots obtained from axillary buds proliferated when they were cultured on a modified MS medium supplemented with combinations of BA and TDZ. Leaves and roots of 'Carefree …

The complex foraging strategy of the specialised gallfly Urophora cardui (Diptera: Tephritidae) for host plants (Cirsium arvense, Asteraceae)
… conspecifics. The females lay eggs into axillary buds in order to initiate gall development. Male and female body size, measured as weight at eclosure or capsule width, was not correlated with male respectively female longevity. Males lived shorter than females. Capsule width of males and females …

BRACKEN (Pteridium aquilinum (L.) Kuhn) STAND CHARACTERISATION ON THE NORTH YORK MOORS: A STUDY OF THE RHIZOME AND FROND SYSTEM WITH REGARD TO A LARGE SCALE CONTROL PROGRAMME
… chemical control using asulam are: the number of buds likely to remain viable afterwards; the rhizome biomass which may effect herbicide dilution; and the origin of frond production which may affect herbicide distribution. The effect of asulam was to cause severe localised damage to buds and …

Anatomical Developments and the Role of Carbohydrate or Mineral Nutrient Deficiency in Bud Necrosis of 'Riesling' grapevines (Vitis Vinifera L.)
… of ultrathin (1micro m) sections of 'Riesling' buds under a light microscope revealed a zone of compressed cells immediately beneath the primary bud axis within 60 days after budbreak. Cell rupture occurred in that zone within 90 days after budbreak. Scanning electron microscopy revealed a …

The Roles of WT1 and BASP1 in the Development and Maintenance of the Posterior Taste Field
… Those taste receptor cells are housed in taste buds. Within each taste bud, there are type I, type II, type III and basal cells, which have different morphological structures and different cellular functions. In mammals, taste buds are located in 3 distinct sets of specialized taste papillae …

The role of auxin transport in the control of shoot branching
… is regulated through the activity of axillary buds, which grow into branches. Several classes of plant hormones have been shown to play pivotal roles in regulating bud outgrowth. Auxin derived from the primary shoot apex and active branches inhibits bud outgrowth, whereas cytokinin promotes it. …
