By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Isotopes. According to news reporting originating from Pullman, Washington, by NewsRx correspondents, research stated, "Photosynthetic carbon isotope discrimination is a non-destructive tool for investigating C-4 metabolism. Tuneable diode laser absorption spectroscopy provides new opportunities for making rapid, concurrent measurements of carbon isotope discrimination and CO2 assimilation over a range of environmental conditions, and this has facilitated the use of carbon isotope discrimination as a probe of C-4 metabolism."
Our news editors obtained a quote from the research from Washington State University, "In spite of the significant progress made in recent years, understanding how photosynthetic carbon isotope discrimination measured concurrently with gas exchange relates to carbon isotope composition of leaf and plant dry matter remains a challenge that requires resolution if this technique is to be successfully applied as a screening tool in crop breeding and phylogenetic research. In this review, we update our understanding of the factors and assumptions that underlie variations in photosynthetic carbon isotope discrimination in C-4 leaves."
According to the news editors, the research concluded: "Closing the main gaps in our understanding of carbon isotope discrimination during C-4 photosynthesis may help advance research aimed at developing higher productivity and efficiency in key C-4 food, feed, and biofuel crops."
