Plant natural products have been used for centuries to treat human illnesses, as recreational substances, and flavoring coloring agents in our food. Nowadays, commercial-scale manufacturing of plant using extraction from resources or chemical synthesis poses challenges environmental sustainability, such species overexploitation. Bio-based microbial cell factories can offer an attractive alterna...

The rhizosphere is a hot spot of soil microbial activity and largely fed by root exudation. carbon (C) exudation flux, coupled with plant growth, considered strategy plants to facilitate nutrient uptake. C accompanied release nutrients. Nitrogen (N) phosphorus (P) co-limit the productivity plant-microbial system. Therefore, C:N:P stoichiometry exudates should be linked economies, functional tra...

Natural products involved in plant-plant and plant-microorganism ecological interaction (Allelochemicals) are an important potential source for alternative agrochemicals and pharmaceuticals, in order to solve the many problems derived from inadequate culture practices and abuse of synthetic herbicides. Isolation, structural determination, bioassay techniques and applicability for these compound...

An object-oriented, automata-based approach for the modelling of plant as well as products is presented. The di erent units of a plant are modelled as nite-state automata and products are represented by means of their recipes. A graphical high-level language to describe recipes is presented and special attention is given to synchronization mechanisms between units when material ow is involved.

NATURE | VOL 411 | 14 JUNE 2001 | www.nature.com 843 Collectively, plants produce a remarkably diverse array of over 100,000 low-molecular-mass natural products, also known as secondary metabolites. Secondary metabolites are distinct from the components of intermediary (primary) metabolism in that they are generally nonessential for the basic metabolic processes of the plant. Most are derived f...

Plant protection products are used in agriculture to improve yields, but this use can cause contamination of the environment and is also likely to have adverse short and long term effects on agricultural workers. This poster describes a systems approach to reducing the risk of operator exposure to plant protection products through the introduction of ergonomics to the design process of large ag...

Simple and effective extraction methods based on matrix solid-phase dispersion (MSPD), dispersive liquid-liquid microextraction (DLLME), and solid-phase extraction (SPE) coupled with high-performance liquid chromatography with diode array detector (HPLC-DAD) were developed to determine triketone herbicides-sulcotrione (SUL), mesotrione (MES), tembotrione (TEMB), and their degradation products-i...

The gradual transition from the long-standing use of monodrug therapy in classical medicine to the new concept of a multidrug and multitarget therapy has great implications for the research strategies of natural products chemistry and phytomedicine. The rationalization of the new strategies, however, requires great efforts in: standardization of monoand multiphytopreparations using all availabl...

“General pronouncements on the significance of the plant acids are at present probably of little value. . . The true significance of the acid metabolism of plants may perhaps lie close to Kostytchev’s later point of view that these acids are the building stones from which some of the complex plant products originate. . . The plant acids are possibly convertible into amino acids and proteins, co...
