Scientists engineer 干ばつ-抵抗力のある 刈るs that 要求する 25% いっそう少なく water and could help 料金d the world
- 農業 要求するs the use of about 90 per cent of 全世界の freshwater 供給(する)s?
- But 生産/産物 still needs to 増加する to 料金d this century's growing 全住民
- For the first time, scientists have 改善するd how a 刈る uses water by 25 per cent
- 研究員s did this by altering the 表現 of one 遺伝子 設立する in all 工場/植物s
農業 uses up 90 per cent of 全世界の freshwater and yet 生産/産物 still needs to 劇的な 増加する to 料金d this century's growing 全住民.
For the first time 研究員s have 改善するd how a 刈る uses water by 25 per cent - without 妥協ing the 工場/植物's 産する/生じる.
専門家s did this by altering the 表現 of just one 遺伝子 that is 設立する in all 工場/植物s. When water is 限られた/立憲的な, these 修正するd 工場/植物s will grow faster and 産する/生じる more than their 非,不,無-修正するd 相当するものs, they 設立する.

For the first time 研究員s have impr oved how a 刈る uses water by 25 per cent - without 妥協ing 工場/植物s 産する/生じるs. 研究員s 熟考する/考慮するd how to make food 刈るs more 生産力のある and resilient to a changing 気候 using タバコ (pictured)
To engineer the 工場/植物s, the 研究員s 増加するd the levels of a photosynthetic protein (PSbS).?
This protein tricks the 工場/植物 into 部分的に/不公平に の近くにing their stomata to 保存する water while the?microscopic pores in the leaf 許す water to escape through the 過程 of transpiration.?
The team 改善するd the 工場/植物's water-use-efficiency - the 割合 of 炭酸ガス entering the 工場/植物 to water escaping - by 25 per cent, without 意味ありげに sacrificing 光合成 or 産する/生じる in field 裁判,公判s.
'刈る 産する/生じるs have 刻々と 改善するd over the past 60 years, but the 量 of water 要求するd to produce one トン of 穀物 remains 不変の - which led most to assume that this factor could not change',?said RIPE Director Stephen Long, Ikenberry Endowed 議長,司会を務める of 工場/植物 Biology and 刈る Sciences.?
'証明するing that our theory 作品 in practice should open the door to much more 研究 and 開発 to 達成する this all-important goal for the 未来.'
Stephen P. Long, a professor of 刈る sciences and of 工場/植物 biology (centre), with postdoctoral 研究員s Johannes Kromdijk, (left) and Katarzyna Glowacka, developed 刈るs that use water 25 パーセント more efficiently by 上げるing the level of a protein
'These 工場/植物s had more water than they needed, but that won't always be the 事例/患者,' said co-first author Katarzyna Glowacka, a postdoctoral 研究員 who led this 研究 at the Carl R. Woese 学校/設ける for Genomic Biology (IGB) at the University of Illinois at Urbana-Champaign.?
The 炭酸ガス 集中 in our atmosphere has 増加するd by 25 per cent in just the pat 70 years, 許すing the 工場/植物 to amass enough 炭酸ガス without fully 開始 its stomata pores.?
There are four factors that can 誘発する/引き起こす stomata to open and の近くに: 湿度, 炭酸ガス levels in the 工場/植物, the 質 of light and the 量 of light.?
The 研究員s (人命などを)奪う,主張する that this is the first 熟考する/考慮する to 報告(する)/憶測 '切り開く/タクシー/不正アクセスing stomata l 返答 to the 質 of light.'???
'進化 has not kept pace with this 早い change, so scientists have given it a helping 手渡す,' said Dr Long, who is also a professor of 刈る sciences at Lancaster University.?
For this 熟考する/考慮する, the team 実験(する)d their hypothesis using タバコ, a model 刈る that is easier to 修正する and faster to 実験(する) compared to other 刈るs.?
Soybeans grow at the South Farms at the University of Illinois. 研究員s 改善するd the 工場/植物's water-use-efficiency - the 割合 of 炭酸ガス entering the 工場/植物 to water escaping - by 25 per cent, without 意味ありげに sacrificing 光合成 or 産する/生じる in fie ld 裁判,公判s
For the first time, scientists have 改善するd how a 刈る uses water by 25 per cent, without 妥協ing the 工場/植物s 産する/生じる. 研究員s did this by altering the 表現 of just one 遺伝子 that is 設立する in all 工場/植物s. Corn grows at the South Farms at the University of Illinois
Now, the 研究員s say they will 適用する their 発見s to 改善する the water-use-efficiency of food 刈るs and 実験(する) their efficacy in water-限られた/立憲的な 条件s.?
'Making 刈る 工場/植物s more water-use efficient is arguably the greatest challenge for 現在の and 未来 工場/植物 scientists,' said co-first author Johannes Kromdijk, a postdoct oral 研究員 at the IGB.?
'Our results show that 増加するd PsbS 表現 許すs 刈る 工場/植物s to be more 保守的な with water use, which we think will help to better 分配する 利用できる water 資源s over the duration of the growing season and keep the 刈る more 生産力のある during 日照り続き,' he said.?
The 研究, published in the 定期刊行物 Nature Communications, is part of the international 研究 事業/計画(する) 'Realizing 増加するd Photosynthetic Efficiency (RIPE)'.?
