The initial reaction in the pathway leading to the production of indole-3-acetic acid (IAA) in plants is the reaction between chorismate and glutamine to produce anthranilate, catalysed by the enzyme anthranilate synthase (ASA; EC 4.1.3.27). Compared with non-transgenic controls, leaves of transgenic poplar with ectopic expression of the pine cytosolic glutamine synthetase (GS1a; EC 6.3.1.2) pr...

Plant extracts, made by grinding 2 g of fresh tissue in 5 ml of water, were toxic to Tylenchorhynchus dubius and Hoplolaimus spp. Such extracts from leaves and stems of bean (Phaseolus vulgaris L.) and leaves of tobacco (Nicotiana tabacum L.) were most toxic; those from leaves of corn (Zea mays L.), tomato (Lycopersicon esculentum Mill.) and rhododendron (Rhododendron catawbiense L.) were less ...

Consumed substances, including food, drink, and tobacco, produced in the environment are exposure sources of Cd. The object of the present study was to estimate Cd exposure and absorption amount from smoking cigarettes, one exposure source of Cd, using recent findings from Japan. The market share of cigarettes produced in foreign countries has increased in Japan, the proportion of tobacco leave...

three bacteria from a tobacco industry effluent and one from a sewage sample were isolated on a medium comprising of 1% tobacco powder as sole source of nutrients. bacteria isolated from the industrial waste water were identified as bacillus cereus, b. alvei and b. circulans. while, lactobacillus sp. was isolated from the sewage sample. the bacteria were optimized for various growth conditions ...

Utilization organic fertilizers is one of the efforts from agricultural sector to preserve environment. The application fertilizer not only reduces use inorganic but also accumulation waste and increases quality crop yields at right dose type. This study utilizes substrate straw mushroom growing media as a mixture plant medium for Tobacco. used made liquid coffee waste, cow urine, goat Kipahit ...

An activated carbon as adsorbent is derived from waste tendu leaves (Diospyros melanoxylon) from local Beedi (Cigarette) industry for removal of sulphur dye from textile waste water. Tendue leaves were chemically treated with sulphuric acid and activated carbon prepared was analyzed by pH, moisture content, ash content, bulk density and BET surface area. The adsorption studies were performed as...

Ethylene is a plant hormone that influences many aspects of plant growth and development (10). The biosynthetic pathway of ethylene production in higher plants is well defined. The rate-limiting step in this pathway is the reaction catalyzed by ACC' synthase (S-adenosyl-L-methionine methyl-thioadenosine-lyase, EC 4.4.1.4), which converts Sadenosyl-L-methionine to ACC. Tobacco (Nicotiana tabacum...

The hypothesis that net photosynthesis is diminished in many plant species because of a high rate of CO(2) evolution in the light has been tested further. High rates of CO(2) output in CO(2)-free air in comparison with dark respiration were found in Chlamydomonas reinhardi, wheat leaves, tomato leaves, and to a lesser extent in Chlorella pyrenoidosa by means of the (14)C-photorespiration assay....
