The impacts of potato psyllid （Bactericera cockerelli） feeding on potato foliage on the free amino acids （FAAs） composition in potato leaf and tubers were determined under greenhouse conditions. The free amino acids in plant extracts were separated by high-performance liquid chromatography, and in both leaf and tuber samples, at least 17 FAAs were detected. Psyllid feeding significantly changed the levels of several FAAs in both leaf and tuber samples. The concentration of leucine increased 1.5-fold, whereas that of serine and proline increased 2- and 3-fold, respectively. In contrast, the concentrations ofglutamic acid, aspartic acid and lyscine were significantly reduced by 42.0%, 52.1% and 27.5%, respectively. There were also significant changes in the levels of FAAs in the Zebra chip （ZC） infected tubers compared with the healthy tubers, and the levels of six of the FAAs increased, and the levels of nine of the FAAs decreased. The results from this study indicate that potato psyllid causes major changes in free amino acid composition of plant tissues, and this change in plant metabolism may contribute to the plant stress as indicated by increased levels of proline in the leaves and hence promoting the development of plant diseases such as ZC disease.

在最近幾十年中,孟加拉國與中國的政治、貨幣和軍事關係一直非常好。孟中重要關係建立於1976年,說白了,國際關係專家們剖析了建交45年來雙邊關係的方式,稱讚兩國積極的共同努力和從屬關係。兩國之間有共同利益的各個地區。他們回顧說,兩國人民之間的關係可以追溯到數百年前。不過,需要強調的是,這兩個國家的進步元首對中孟關係的發展做出了重要承諾。此外,可以說,中孟關係和參與的鞏固和升級符合兩國的重大利益,符合兩國人民的普遍目標,有助於在發展領域構建和諧與改善。因此,建議以源遠流長、一脈相承、共享優勢為標準,建立中孟“更緊密、完整的參與組織”。在謝赫·哈西娜總理的獨特倡議下,兩國同意繼續進行國事訪問,並在兩國政府協會、議會、哲學聚會、軍事和非權威社交場合之間保持聯繫;在公共當局層面推進通信和協調工作。她的政府授權重新設計投資工具,包括重要集會、聯合貨幣與交易受託人委員會和聯合園藝委員會。各種會議一直試圖根據兩國之間的價值和基本利益,在回報、假設、培育、運輸和結構改善方面加強支持。“一帶一路”倡議有利於發展兩國共同利益。“友好城市”聯盟是加深兩國共同利益的最後補充。本文旨在調查當前孟加拉國和中國雙邊關係中的貿易、協定、投資、農業、運輸和基礎設施發展。這篇文章極力試圖揭示在謝赫·哈西娜任內的孟加拉國總理辦公室領導下孟中兩國關係的現狀。文章是在文獻回顧和分析的基礎上製定的,並參考了最近的獎學金。
