C ₄ photosynthesis in <i>Paulownia</i> ? A case of inaccurate citations

Societal Impact Statement C 4 photosynthesis is an ultra‐efficient mode of found in some our most productive crop species yet notably rare trees. Given associated with high yield herbaceous species, especially under hot and dry conditions, trees may seem attractive prospect for biomass production carbon sequestration a rapidly changing climate. This explain why the literature have optimistically linked exceptionally fast‐growing tree Paulownia. However, this claim lacking evidence represents example poor citation practices leading to spread misinformation. Summary The rapid growth genus Paulownia (Paulowniaceae) has been attributed their use photosynthesis, complex trait that confers increased photosynthetic efficiency certain environmental conditions. After careful examination citations used support idea we find there no data underpinning claim. Despite this, many investment schemes utilise information about physiology , including type, legitimise financial offsetting. study uses leaf physiology, anatomy stable isotope determine whether or not three ( tomentosa fortunei kawakamii ) photosynthesis. These are compared existing 3 woody literature. We show phenotypes considered consistent those plants. Our findings highlight how inaccurate scientific can contribute misinformation beyond community, as promoting investments plantations reference superiority means its
