Researchers from Tohoku University and Iwate University in Japan
released a review article on enhancing photosynthesis and yield in
riceby improving nitrogenuse efficiency. The report is published
in/Plant Science/.

The success of the dwarf breeding of rice, which led to the Green
Revolution in Asia, is attributed to the increased source and sink
capacities depending on significant N fertilizer applications. Though N
fertilizer is vital for cereal production, large applications impact the
environment.

Studies have shown thatgenetically engineeredrice overproducing Rubisco
had improved yields and enhanced N use efficiency. This facilitates
higher biomass production under high N fertilization in a paddy field.
The rice cultivar, Akita 63, exhibited high yields by expanding the sink
capacity without source enhancement. Thus, the authors concluded that
developing rice with both high photosynthesis and large sink capacity is
vital.
