It has previously been shown that the nucleotide sequences of the Agrobacterium rhizogenes rolC locus and the selective marker nptII developed mutations during the long-term cultivation of transgenic cell cultures of Panax ginseng. In the present report, we analyzed the nucleotide sequences of selected plant gene families in the 20-year-old P. ginseng 1c cell culture and in leaves of cultivated...

This study aimed to explore the ecological adaptability and the possibility of growing rice with floating bed on the dilute biogas slurry. The results of the experiments show that the growth stage, rice plant height, and rice yield and quality were significantly affected by multiple dilutions; rice plants cultivated with 45 multiple dilutions had better ecological adaptability than others. In t...

Plants are one of the two major groups of living organisms that are an essential entity to the function of the biosphere. Plants can be found in all known parts of the earth, in all shapes and sizes. They include the green algae, mosses, ferns, vines, grasses, bushes, herbs, flowering plants and trees. Although some plants are parasitic, most produce their own food through photosynthesis. Most ...

Tea is one of the most popular beverages across the world and is made exclusively from cultivars of Camellia sinensis. Many wild relatives of the genus Camellia that are closely related to C. sinensis are native to Southwest China. In this study, we first identified the distinct genetic divergence between C. sinensis and its wild relatives and provided a glimpse into the artificial selection of...

Aromatic plants are plants that possess aromatic compounds, most of which are essential oils which are volatile in room temperature. They have traditionally been used as raw materials for extraction of essential oils (which, in turn, are used in the flavor and fragrance industries), as well as the sources of spices, herbs, and other natural products such as traditional medicines, pharmaceutical...

Whiteflies damage tomatoes mostly via the viruses they transmit. Cultivated tomatoes lack many of the resistances of their wild relatives. In order to increase protection to its major pest, the whitefly Bemisia tabaci and its transmitted Tomato Yellow Leaf Curl Virus (TYLCV), we introgressed a trichome-based resistance trait from the wild tomato Solanum pimpinellifolium into cultivated tomato, ...

Surveys were conducted in Alexandria, El-Behera, and Matrouh Governorates in northwestern Egypt during the 1994-1998 cropping seasons to study the occurrence, population density, host associations, and distribution of phytoparasitic nematodes associated with 35 major crops, grasses, and weeds. A total of 220 soil and root samples containing mixed populations of 26 genera and 38 species of phyto...
