AB - <jats:p>&lt;p&gt;Understanding the mechanisms underlying changes in carbon isotope discrimination (&amp;#916;&lt;sup&gt;13&lt;/sup&gt;C) in C&lt;sub&gt;3&lt;/sub&gt; and C&lt;sub&gt;4&lt;/sub&gt; plants is critical for predicting the C&lt;sub&gt;3&lt;/sub&gt;/C&lt;sub&gt;4&lt;/sub&gt; fraction in mixed ecosystems. Variations in &amp;#916;&lt;sup&gt;13&lt;/sup&gt;C are closely related to changes in the stomatal limitation of photosynthesis (i.e. the ratio of leaf internal to ambient partial pressure of CO&lt;sub&gt;2&lt;/sub&gt;, &lt;em&gt;c&lt;/em&gt;&lt;sub&gt;i&lt;/sub&gt;/&lt;em&gt;c&lt;/em&gt;&lt;sub&gt;a&lt;/sub&gt;), which are in turn determined by environmental variables, but also depend on the pathway of carbon assimilation. For instance, isotopic fractionation during the diffusion of CO&lt;sub&gt;2&lt;/sub&gt; through the stomata primarily influences &amp;#916;&lt;sup&gt;13&lt;/sup&gt;C in C&lt;sub&gt;4&lt;/sub&gt; plants, while fractionation during Rubisco carboxylation has a stronger imprint on &amp;#916;&lt;sup&gt;13&lt;/sup&gt;C in C&lt;sub&gt;3&lt;/sub&gt; plants. As a result, C&lt;sub&gt;3&lt;/sub&gt; plants are depleted in &lt;sup&gt;13&lt;/sup&gt;C compared to C&lt;sub&gt;4&lt;/sub&gt; plants. Isotopic measurements can thus be used as tracers of physiological processes in plants.&lt;/p&am
