Better understanding of the basic science underpinning rubisco\u2019s function, therefore, has implications for increasing agricultural yields, improving carbon sequestration technology and understanding how plants may adapt to a warming climate.<\/p>\n<p>In the paper \u201c<a href=\"https:\/\/www.pnas.org\/doi\/10.1073\/pnas.2519914123\"> Rubisco Kinetic Acclimation at the Holoenzyme Level<\/a>,\u201d published April 15 in Proceedings of the National Academy of Sciences, the researchers demonstrate that while rubisco\u2019s protein core remains consistent, parts of its exterior can be swapped out, akin to an outfit. A stiffer exterior is preferred in the heat, for protection, and a looser one in the cold, to increase efficiency. This study, using the mustard-family plant Arabidopsis, is the first to show how rubisco acclimates to temperature changes in any plant species.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Humans adjust to changes in temperature by putting on a sweater or taking off layers.
