Scientists debunk potential link to crop cold tolerance
(PHYSorg.com Biology)

When temperatures drop, the enzyme Rubisco that fuels plant growth and yield gets sluggish. Many crops compensate by producing more Rubisco; however, scientists speculated that some crops may lack space in their leaves to boost the production of this enzyme, making them more susceptible to cold. A new study from the University of Illinois and the Massachusetts Institute of Technology refutes this theory but found these crops are far from reaching their photosynthetic potential.
