Although China and India are the two largest tea-producing countries, the domestication origin and breeding history of the tea plant in these two countries remain unclear. Our previous study suggested that the tea plant includes three distinct lineages (China type tea, Chinese Assam type tea and Indian Assam type tea), which were independently domesticated in China and India, respectively. To d...

Plant growth promoting rhizobacteria (PGPR) are studied in different agricultural crops but the interaction of PGPR of tea crop is not yet studied well. In the present study, the indigenous tea rhizobacteria were isolated from seven tea estates of Darjeeling located in West Bengal, India. A total of 150 rhizobacterial isolates were screened for antagonistic activity against six different fungal...

Tea-ginger drink was selected for evaluation due to its nutraceutical potential. Panelists rated preference for drinks prepared from tea, ginger, and tea+ginger powder for colour, taste, and aroma. The obtained data were evaluated using analysis of variance, principal component analysis, and agglomerative hierarchical clustering. Also the colour preference scores were evaluated against instrume...

Several species of plant parasitic nematodes have been encountered in tea soils in different tea-growing areas of the world. Roots and soil were sampled for the presence of plant-parasitic nematodes from tea plantations in Kusuku, the only major tea growing location in Nigeria. Six genera and species of plant-parasitic nematodes were recovered from the rhizosphere soil. Meloidogyne spp., Pratyl...

In plants, the NAC (NAM-ATAF1/2-CUC) family of proteins constitutes several transcription factors and plays vital roles in diverse biological processes, such as growth, development, and adaption to adverse factors. Tea, as a non-alcoholic drink, is known for its bioactive ingredients and health efficacy. Currently, knowledge about NAC gene family in tea plant remains very limited. In this study...

Tea, a beverage produced by steeping processed top leaves and buds of the tea plant in freshly boiled water, originated in China 2700 BC, but its medicinal properties were know much before that. China was the first country to cultivate tea. In Japan the cultivation began about 200 AD. The use of tea later spread to the other Asian countries. Tea cultivation in India was suggested as early as 17...

INTRODUCTION Jasonia glutinosa is an endemic plant species of the Iberian Peninsula and Southern France traditionally used in infusions as a spasmolytic; this plant is also known as "té de roca" (rock tea) but there is no scientific evidence about the effects of this plant. AIM To evaluate the spasmolytic effect of rock tea. METHODS We have studied the in vitro effect of a rock tea extract ...

Appearance does not easily identify the dried plant fragments used to prepare teas to species. Here we test recovery of standard DNA barcodes for land plants from a large array of commercial tea products and analyze their performance in identifying tea constituents using existing databases. Most (90%) of 146 tea products yielded rbcL or matK barcodes using a standard protocol. Matching DNA iden...

Introduction: Buckwheat (Fagopyrum esculentum) and wild thyme (Thymus serpyllum) leaves and flowers were used to develop thymo-rutin green tea. The process involved cultivation of buckwheat collection of flowers and leaves after flowering and collection of wild thymus leaves and flowers. Materials and Methods: The leaves and flowers washed and pass through steam to fix color and kept in solar h...
