zui近，中國科學(xué)院遺傳與發(fā)育生物學(xué)研究所研究員儲成才（儲成才科學(xué)網(wǎng)博客）研究組在水稻氮高效利用領(lǐng)域的研究取得了新突破，該成果為培育兼具高產(chǎn)與早熟優(yōu)點的水稻品種提供了解決方案，相關(guān)研究2月24日在線發(fā)表在《植物細(xì)胞》雜志中，并被該刊作為該期精品論文推送。

研究人員在前期研究硝酸鹽轉(zhuǎn)運蛋白基因的基礎(chǔ)上，對其同源基因的功能進(jìn)行了進(jìn)一步探索。研究顯示，這種同源基因主要定位于液泡膜，受銨鹽誘導(dǎo)，參與水稻對細(xì)胞內(nèi)硝酸鹽及銨鹽利用的調(diào)節(jié)。由于硝態(tài)氮和銨態(tài)氮是植物利用氮的兩種主要形式，尤其銨態(tài)氮，是水稻的主要利用方式。因此該基因的這種功能分化對水稻環(huán)境適應(yīng)性具有重要意義。

北京、長沙及海南等多年多點的田間試驗表明，這種基因的過表達(dá)植株在高氮和低氮條件下均表現(xiàn)出顯著的增產(chǎn)效果。尤其在低氮條件下，該基因過表達(dá)株系小區(qū)產(chǎn)量以及氮利用效率zui高可提高至60%, 且在高氮條件下可提早開花2周以上，從而有效縮短了水稻成熟時間。該研究成果為培育兼具高產(chǎn)與早熟品種，克服農(nóng)業(yè)生產(chǎn)中高肥導(dǎo)致的“貪青晚熟”問題提供了解決方案，具有巨大的應(yīng)用潛力。

數(shù)年來，中科院遺傳發(fā)育所及其所屬三個國家重點實驗室的水稻氮高效研究團(tuán)隊獲得了系統(tǒng)性的重要成果，在相關(guān)領(lǐng)域引起了廣泛關(guān)注。

"The Bank of communications is carrying the three cultural genes of national finance, pioneer of reform and sustainable sustainable development. As a national financial brand, the Bank of communications has been responsible for the rejuvenation of national finance. Recently, Yu Yali, vice president of the bank at the China banking ingenuity forum says the spirit. She said that in the course of a hundred years of development, the service culture has been infiltrated into the blood and inherited from generation to generation.
In 2017, the bank has always been to effectively support the supply side structural reform, the service of the real economy as a financial source, as a priority among priorities ingenuity service. In order to carry out the task of "three down, one subsidy and one subsidy", the bank will integrate multiple product lines such as financial market, investment banking, information management, leasing and other fields, and improve the combined financial services of "creditor's rights + equity + real right", so as to continuously improve the ability of serving the real economy. Data show that as of the end of the three quarter of 2017, the total assets of the bank group was nearly 9 trillion yuan, an increase of 6.34% compared with the beginning of the year, net profit increased by 3.50% compared with the same period last year, and the balance of customer loans increased by 7.57% compared with the beginning of the year.

On the morning of January 19th, the housing security and Property Bureau of Nanjing signed a strategic agreement on housing lease with the Bank of communications.
The achievements of the reform and development have been recognized by the international authoritative media. On the list of the *000 Bank of the world released by Banker magazine in 2017, the bank ranked eleventh in the total market capitalization of 90 billion 367 million US dollars, ranking 2 higher than that in 2016. This is the top 20 top bank of the world bank for four years in a row.
Play the "two" service advantage "The Belt and Road construction
In addition to supporting the supply side structural reform, the bank actively supported the "The Belt and Road construction.
The relevant person in charge of the vivid case of Henan branch of Bank of communications to support the construction of the "air Silk Road" support and actively participate in Henan Belt and Road Initiative construction to reporters.
In September 2017, the Henan provincial government has issued the "Zhengzhou - Luxemburg" air silk road construction planning "and" advance Zhengzhou Luxemburg air silk road construction work programme ", clearly pointed out:" to 2025 the aircraft leasing industry as a key development and construction of the Silk Road "" in the air industry, actively to carry out a pilot, promote industrial agglomeration, enhance the ability to serve the overall situation of the country."
To this end, in December 2017, the Henan branch of Bank of the head office of "integration, internationalization" of a gilded signboard, give full play to the role of the main force of finance, the Central Plains aviation industry investment cooperation agreement signed with the Central Plains aviation leasing Limited by Share Ltd, the full support of Henan province into a zone of a road construction, to enhance the level of development of aviation industry in Henan province. The two sides will work together to establish a total scale of 3 billion yuan aviation industry investment fund, supporting the development of the aviation industry, mainly for aircraft purchase and leasing business, aviation industry investment and mergers and acquisitions, and aviation industry related business areas investment and construction.
