An additional gene increased the rice yield by up to 40 percent of the usual – Science

The world’s consumption of crops is expanding quickly at the same time that the supply chain is having trouble.

Climate change, depleted soil, and rising costs are all putting it to the test. Around the world, plant breeders are putting a lot of effort into figuring out how to enhance yields.

One answer was discovered by a team of researchers in China. The yield of rice increased by almost half when plant physiologist Wenbin Zhou of the Chinese Academy of Agricultural Sciences and his colleagues transferred one copy of the plant’s own gene to rice.

According to the team’s findings published in the journal Science, the extra gene aids the plant’s utilization of fertilizer, boosts copulation, and hastens flowering.

Over a hundred regulatory genes were screened out to find the now-identified yield booster. Other genes’ functions are impacted by regulatory genes. In order to map the genes that had already been identified as being crucial to linkage, rice and corn were chosen.

In the experiment, the kind of intake doubled.

When rice was grown in low-nitrogen soil, Zhou and his associates kept an eye out to see if any of the investigational genes were turned on. After all, genes that improve food absorption may also be ones that deal with nutritional limitation.

The test was successful. 13 regulatory genes were activated by nitrogen deprivation. Intake of nitrogen was increased by at least four times in five of them.

The researchers then focused their attention on one of them.

They gave some of the rice plants the osdreb1c gene and in turn switched it off in other rice plants. They then watched as the rice in the greenhouse grew.

Plants with the gene deleted grew less well than the control plants. On the other hand, an extra copy of the same gene caused the shoot to grow more slowly and its roots to spread out more.

As determined by the measurement, the rice with the extra gene absorbed more nitrogen than usual. Additionally, they had a third more green cells and the bonding-related rubisco enzyme.

The new gene increases the yield, according to two field trials that lasted up to three years.

A farmer-favored rice variety had a gene introduced that enhanced the yield by up to 40% over the standard amount.

“very impressive It’s unlike anything I’ve ever seen “on the website of Science magazine, praised the plant geneticist Matthew Paul from the Rothamsted Research Institute of Agriculture.

The researchers think that the technique can also be used with other plants. It appears to work on wheat and ryegrass as well, according to preliminary experiments.

If plants exploited light more effectively than they do now, there would be adequate food for the expanding human population. Read more: Researchers are attempting to improve communication by transferring genes.

The EU forbids the use of the technology in Europe, despite researchers being able to quickly generate food plants that once required thousands of years to perfect.
