Fractionation of carbon isotopes in oxygenic photosynthesis product 3-phosphoglycerate is depleted in C due to the kinetic isotope effect of the above reaction. The overall C fractionation for C3 photosynthesis ranges between -20 to -37‰. The wide range of variation in delta values expressed in C3 plants is modulated by the stomatal conductance, or the rate of CO entering, or water vapor exiting, the small pores in the epidermis of a leaf. The δC of C3 plants depends on the relationship between stomatal conductance and photosynthetic rate, which is a good proxy of water use efficiency in the leaf. C3 plants with high water-use efficiency tend to
What I Need has done wrong. Despite its sap factor, "What I Need" will likely lap up radio play." The remix version with West Coast rappers Nate Dogg, Shorty Mack, Slim Thug and Snoop Dogg became even more popular being watched more than 200,000 times on YouTube. It's called "Smokin Trees (What I Need Remix)" and produced by Ray J for Knockout Entertainment and was expected to be released as "Smokin Smokin Weed" which featured Ray J, Nate Dogg and Snoop Dogg only, on "Tha Blue Carpet Treatment" by Snoop Dogg. What I Need "What I Need" is a song by American recording
