Plants soybean

Plant. Soybeans grow on erect, bushy aimual plants, 75—125 cm high, having hairy stems and trifoliate leaves. The flowers are white or purple or combinations thereof. Growing season varies with latitude and is 120—130 d in central Illinois.

In terrestrial ecosystems the symbiotic bacteria, particularly strains from the genus Rhizobium, play the most important role in N fixation. These bacteria are found on the roots of many leguminous plants (soybeans, clever, chickpeas, etc.). There are other symbiotic diazotrophs (nitrogen-fixing microbes), but till now the Rhizobium has been the most extensively studied.

The acetylenic analog of Mead Acid, 5,8,11-eicosatriynoic acid, was reported to be a selective inhibitor of platelet 12-lipoxygenase. Acetylenic fatty acids also inhibited 15-lipoxygenases of plant (soybean) as well as of animal (rabbit reticulocyte) origin. The nature of the acetylenic compound significantly affected its activity on the soybean enzyme, but not the rabbit enzyme. For the former, 7,10,13-eicosatriynoic acid was the most powerful inactivator. Addition of a fourth triple bond at position 4 or 5 strongly reduced the rate of inactivation. On the other hand, the rabbit reticulocyte enzyme was inactivated almost equally well by the various acetylenic fatty acids that were tried. The mechanism of inactivation of lipoxygenases was also suicide inhibition . ... 

In the 2002-2003 growing season, 30.6 million metric tons of soybean oil were produced worldwide, constituting about half of the worldwide edible vegetable oil production, and thirty percent of all fats and oils produced, including animal fats and oils derived from tropical plants. Soybean oil is produced in larger amounts than any other traded oil (about 23 million tonnes a year) and is grown particularly in the United States, followed by Brazil, Argentina, and China. ... 

Soybeans are the number one oilseed crop world-wide. In 2005, a total of 210 mio metric tonnes of soybean were produced. Relatively few countries produce soybeans the USA accounts for more than 40% of the world production, with Brazil, Argentina and China together accounting for an additional 55%. In Europe, Italy, Russia and the Ukraine are the main producer countries. In the USA, Brazil and Argentina, the most widely planted soybeans are genetically modified varieties (GMO), which are tolerant against the herbicide glyphosate. 

Chibu and Shibayama (2001) applied chitosan at concentration of 0.1%-0.5% in soil-planted soybean, upland rice, mini-tomato, and lettnce. The results showed that there was increase in chlorophyll density of chitosan-treated plant compared to the control. The leaves of the plant treated with chitosan were more dark green than the control.

M2 lxlng soybeans had higher amounts of 16 0 In the pods than non-nodulated plants (Table 1). Mycorrhlzal soybeans contained less 18 3 (9c, 12c, 150 and less 20 0 In the pod, but comparatively more 22 0 than did P- ertlllzed plants. Soybeans Inoculated lth Bradyrhlzoblum had a higher content of 16 0 and 18 0 In the seed than did non-nodulated plants (Table 1). M2 flxlng plants contained more 18 1 (llO, 18 2 (9 ,12 ), and 18 3 (9 ,12 , 15 ) In the seed than did N-fertlllzed plants.
