Through analyzing 46 kinds of flowers, we found that rosa l. ( rosaceae ), lagerstroemia indica l., euphorbia antiquorum l., rhododendron l. osmanthus fragrans lour, had strong aoa and abundant polyphenols ; the relationship between aoa and polyphenols contents of flowers are significant at 1 % level. 2. the aoa of rose flowers was confirmed through five methods
採集並比較了46種常見花卉的抗氧化活性及其多酚、黃酮含量，發現玫瑰花、大葉紫薇花、鐵海棠花、杜鵑花、桂花具有很高的抗氧化活性，同時含有豐富的多酚類物質，花卉的抗氧化活性與其多酚含量呈顯著的正相關； 2705bp dna fragment of mxnrampl gene and full cdna of mxlrtl gene which were related to resist iron stress were cloned by using malus xiaojinensis cheng et jiang - the first iron - efficient genotype in the genus malus in the world as material. ( 1 ) using fragment of nramp gene from wheat and fe ( ll ) - transporter gene fragment of maize ( zmlrt ~ ) as probes, we analysed these genes by blotting hybridization technique in malus xiaojinensis cheng et jiang
本實驗以中國農業大學園藝植物研究所篩選到的一個蘋果鐵高效基因型? ?小金海棠（ malusxiaojinensischengetjiang ）為試材，分別克隆了小金海棠的抗缺鐵相關基因mxnramp1基因的752bp基因組dna片段和fe （ ） -轉運蛋白基因（ mxirt1 ）的cdna全長，為深入探討小金海棠抗缺鐵的分子機理奠定了基礎。The purposes of this project were to further analyze the characteristics of their iron efficiency under iron stress, to study the physiological and molecular mechanisms of iron efficiency under iron deficiency in c. junos and m. xiaojinensis, and to analyze the spatial expression model of fcr ( ferric chelate reductase ) gene under iron stress with the hope to cast a new light on iron stress tolerance on the molecular level, to lay solid foundations for cloning fcr gene in c. junos and m. xiaojinensis, and to provide some basic data for creating new rootstocks with excellent complex characters and iron efficiency
本研究通過進一步分析香橙和小金海棠的耐缺鐵特性，研究它們耐缺鐵的生理原因和分子基礎，並通過分析三價鐵螯合物還原酶基因的空間表達模式，從分子水平上去探討植物耐缺鐵的原因，為從香橙和小金海棠中克隆三價鐵螯合物還原酶基因奠定基礎，並為人工創造耐缺鐵的果樹砧木提供基礎研究數據。The study was undertaken to isolate fe ( ii ) - transporter cdna and related binding protein cdna under fe - deficiency stress from a fe - deficiency root cdna expression library of malus xiaojinensis by screening library using maize fe ( ii ) - transporter cdna and wheat tamre - bp cdna as a probe. the main results as follows : 1 out of approximately 120000 plaques, four positive cdna clones encoding fe ( ii ) - transporter proteins, designated pftl -
本試驗以蘋果屬小金海棠（ malusxiaojinensischengetjiang ）為試材，利用玉米fe （ ）轉運蛋白基因片段以及小麥金屬反應元件結合蛋白tamre - bpcdna為探針，篩選小金海棠缺鐵根cdna表達文庫，目的在於克隆蘋果鐵高效基因型小金海棠的fe （ ）轉運蛋白基因以及與缺鐵脅迫相關的結合蛋白基因。C. junos and m. xiaojinensis were found to be tolerant to iron chlorosis and were able to acquire iron from soils of low iron availability in previous field experiments, but the physiological and molecular mechanisms for their iron efficiency have remained unclear
基於此，本研究選擇了兩種果樹砧木，小金海棠和香橙因為它們在初步的田間鑒定中表現耐缺鐵，但它們耐缺鐵的生理及分子機制並不清楚。( 3 ) 490bp cdna fragment of fe ( ii ) - transporter gene mxlrtl was cloned by using common pcr method from iron - stressed root cdna library of malus xiaojinensis cheng et jiang with primers designed according to the conserved domain sequences of plant irt gene families. then we cloned the full cdna of mxlrtl gene by race method from this library with primers designed according to the sequence of 490bp cdna fragment
（ 3 ）根據植物irt基因家族的功能保守區序列設計引物，首先通過常規pcr法從缺鐵脅迫處理的小金海棠根系cdna文庫中克隆了fe （ ） -轉運蛋白基因mxirt1的490bp的片段，然後根據測序結果設計引物，通過race法從該cdna文庫中克隆了mxirt1基因的cdna全長。This suggests that mxmybl represents a single copy gene in the genome of mains xiaojinensis. 8 expression pattern was analysed by northern blot and rt - pcr. the results showed that mxmybl mrna was expressed in root and leaf and it was strengthened expression by the treatment of fe - deficiency for three days in roots especially
8 、 northcm雜交結合rtpcr的方法對mxmybl基因在小金海棠中的表達模式進行了分析，結果如下： mxmyb在根系和葉片中均表達，缺鐵處理可以加強mxmybl在根系中的表達，尤其是缺鐵3天的根系表達量最強。5 out of approximately 120000 plaques, ten positive cdna clones were isolated from a fe - deficiency root cdna expression library of malus xiaojinensis by screening library for three times using tamre - bp cdna as a probe, then two representative clones were 5 " sequenced
5 、用小麥金屬反應元件tamre - bpcdna作探針，篩選小金海棠缺鐵根cdna表達文庫，通過對約120000pfu的文庫進行三輪篩選，共獲得10個陽性克隆。分享友人
