In
collaboration with researchers at Nanjing Agricultural University, Dr
Tony Miller from the John Innes Centre has developed rice crops with an
improved ability to manage their own pH levels, enabling them to take up
significantly more nitrogen, iron and phosphorous from soil and
increase yield by up to 54 percent.
Rice is a
major crop, feeding almost 50 percent of the world's population and has
retained the ability to survive in changing environmental conditions.
The crop is able to thrive in flooded paddy fields - where the soggy,
anaerobic conditions favour the availability of ammonium - as well as in
much drier, drained soil, where increased oxygen means more nitrate is available. nitrogen fertilizer is a major cost in growing many cereal crops and its overuse has a negative environmental impact.
The nitrogen that all plants need to grow is typically available in
the form of nitrate or ammonium ions in the soil, which are taken up by
the plant roots. For the plant, getting the right balance of nitrate and
ammonium is very important: too much ammonium and plant cells become
alkaline; too much nitrate and they become acidic. Either way, upsetting
the pH balance means the plant's enzymes do not work as well, affecting
plant health and crop yield.
Together with the partners in Nanjing, China, Dr Miller's team has been working out how rice plants can maintain pH under these changing environments.
Rice contains a gene called OsNRT2.3, which creates a protein
involved in nitrate transport. This one gene makes two slightly
different versions of the protein: OsNRT2.3a and OsNRT2.3b. Following
tests to determine the role of both versions of the protein, Dr Miller's
team found that OsNRT2.3b is able to switch nitrate transport on or
off, depending on the internal pH of the plant cell.
When this 'b' protein was overexpressed in rice plants they were
better able to buffer themselves against pH changes in their
environment. This enabled them to take up much more nitrogen, as well as
more iron and phosphorus. These rice plants gave a much higher yield of
rice grain (up to 54 percent more yield), and their nitrogen use
efficiency increased by up to 40 percent.

being able to produce more of the world's food with a lower
