Taste buds and papillae in tongues of rhesus monkeys were examined and counted to determine if there are age-related differences in general morphology or numbers of receptor organs. Tongues from 15 monkeys in five groups aged 4-31 years were studied with light microscopy. Fungiform, circumvallate, and foliate papillae were examined and taste buds in each papilla type were counted. Numbers of pa...

Real-time budding dynamics of multicomponent, tubular lipid vesicles was investigated. By using a fluorescence microscope, three typical growth modes of the buds were observed, corresponding, respectively, to bud growth through coalescence between flat patches, a bud and a patch, as well as that of two buds. The spatial and temporal scales measured in the observation were used to estimate the b...

The competence of pedicel explants of tobacco (Nicotiana tabacum L. cv Samsun) to regenerate flower buds in response to auxin was manipulated by preincubating excised tissues in the absence of auxin. When exposed to 1 micromolar 1-naphthaleneacetic acid, these tissues formed fewer buds than controls that were not preincubated. The number of buds eventually formed correlated with the 1-naphthale...

Sensory ganglia that innervate taste buds and gustatory papillae (geniculate and petrosal) are reduced in volume by about 40% in mice with a targeted deletion of the gene for brain-derived neurotrophic factor (BDNF). In contrast, the trigeminal ganglion, which innervates papillae but not taste buds on the anterior tongue, is reduced by only about 18%. These specific alterations in ganglia that ...

In mammals, taste buds develop in different regions of the oral cavity. Small epithelial protrusions form fungiform papillae on the ectoderm-derived dorsum of the tongue and contain one or few taste buds, while taste buds in the soft palate develop without distinct papilla structures. In contrast, the endoderm-derived circumvallate and foliate papillae located at the back of the tongue contain ...

Pistachio produces an abundant number of inflorescent buds every year (during spring and early summer) which abscise mainly on fruiting branches during seed development. Competition of the developing ovaries/seeds with inflorescent buds for nutrients was suggested as being primarily responsible for bud abscission. Although leaf N correlated with bud retention, foliar application of N did not re...

Limitations of cuttings become an essential problem in the expansion cassava plantations. One strategy that can be taken is to reduce length and increase plant population area planted produce more stems per unit for next growing season. This study aimed determine effect cutting hectare on growth production stems. The research was carried out at Jambegede Agricultural Technology Research Assessm...
