Taste buds are unusual in requiring ATP as a transmitter to activate sensory nerve fibers. In response to taste stimuli, taste cells release ATP, activating purinergic receptors containing the P2X2 and P2X3 subunits on taste nerves. In turn, the released ATP is hydrolyzed to ADP by a plasma membrane nucleoside triphosphate previously identified as nucleoside triphosphate diphosphohydrolase-2 (N...

Microscopic observation of bi-weekly sampled terminal buds revealed that most flower buds of R. mucronatum were formed between late-July and mid-August and differentiation of specific floral organs was completed before mid-October. Flower buds continued to enlarge through the winter. When flower buds on two-yearold plants from rooted cuttings were allowed to grow at day / night temperature of 1...

The demography of the bud bank and its sprouting capacity are important for understanding the population dynamics of clonal plants and their potential responses to disturbances. To this end, we investigated the size and composition of the bud bank of Miscanthus sacchariflorus (Maxim.) Hack. immediately after flooding (November), in winter (January), in spring (March), and before flooding (May) ...

The peripheral taste system likely maintains a specific relationship between ganglion cells that signal a particular taste quality and taste bud cells responsive to that quality. We have explored a measure of the receptoneural relationship in the mouse. By injecting single fungiform taste buds with lipophilic retrograde neuroanatomical markers, the number of labeled geniculate ganglion cells in...

This study was conducted to assess the response of Gibberellic acid and corm division on floral attributes gladiolus cv. Punjab Dawn at Horticulture Research Farm Institute Agricultural Sciences, Banaras Hindu University, Varanasi, India during two consecutive year (2017-2019). The treatments comprised growth regulators with concentration i.e. GA3 100 ppm 200 including control (distilled water)...
