Rice strongest tsunami Results plants resistant to salt

Were obtained from rice plants resistant to salt and the rice fields suitable for this Japanese tsunami of March 2011 have sprayed salt water and mud, making them unsuitable for cultivation.

The result, described in the journal Nature Biotechnology, is due to a research team led by Japanese and British Ryohei Terauchi, IWA Biotechnology Research Centre.

The rice plants were obtained using a new method called Mut Map, which allows to obtain plants with the desired characteristics in a more 'fast. ''By working with a species already 'is already used by farmers' adapted to local conditions, the method will allow 'to develop new varieties' suitable to the crops in a year, rather than 5 or 10'', said one of the authors, Sophien Kamoun, the Sainsbury Laboratory, UK.

The researchers worked with a variety 'of very fine rice, called Hitomebore, which is grown in northern Japan. At first, trees were obtained with specific genetic mutations in order to obtain desired characteristics, such as the ability 'to produce more beans' large, resistance to drought' and salt. The genetic mutation, and 'was obtained by treating the plants with an agent that causes mutation. The plant achieved and 'was then crossed with wild species of the variety' Hitomebore. From the progeny from the crossing, and 'was then produced for self-pollination (the process in which the pollen falls from the male to the female of the same flower), a second generation of plants suitable for cultivation.

It is estimated that the tsunami of 11 March 2011 has inundated with salt water over 20,000 acres of rice fields in northern Japan and the hope of researchers and 'the new rice obtained can be used just for these fields.
