Boosting photosynthetic efficiency in crop species has long been a goal since efficiency of photosynthesis is a critical factor in crop yield. One strategy for improving photosynthetic rates is enhancing mesophyll conductance to carbon dioxide. Tomeo and  Rosenthal examined 12 cultivars of soybean (Glycine…

South et al. discover a new transporter involved in photorespiration http://www.plantcell.org/content/29/4/808.abstract. Photosynthesis uses solar energy to convert carbon dioxide in the atmosphere into sugars that provide the energy and chemical building blocks for plant growth. A key enzyme in photosynthesis…
