boea 解釋
新雙香豆素,雙香豆素乙酯
  1. Deng et al. ( 2000 ) found an obvious increase in carotenoids content in detached boea leaves during dehydration, indicating a protective role of xanthophylls cycle in dehydrated boea leaves

    鄧馨等（ 2000 ）的研究結果發現牛耳草離體葉片在脫水過程中類胡蘿卜素的含量顯著增加，推測可能存在葉黃素循環的保護作用。
  2. The results of treatments with different concentration of phosphate in the present study indicated, whether boea leaves were treated before desiccation or during rehydration, and whether they were intact leaves, leaf halves or leaf discs, the boea leaves were injured and their photochemical activity of psii were serious affected by treatment with 0. 1mol / l phosphate or over, thus resulted in poor resurrection for dehydrated boea leaves. the photochemical activity of psii was a sensitive parameter of physiological activities for boea leaves during dehydration and rehydration

    本文利用不同濃度的磷酸鹽溶液處理牛耳草葉片，結果發現，不論是在乾燥前還是在復甦時處理，也不論是處理牛耳草整葉、半葉還是葉圓片， 0 . 1mol l以上的磷酸鹽溶液都對牛耳草葉片具有損傷作用，極大的影響了其光系統的光化學活性，使得牛耳草葉片在脫水后不能很好的復甦。
  3. Leaves detached from mature plant of resurrection plant boea hygrometrica ( bunge ) r. br

    本文在鄧馨的研究基礎上以復甦植物牛耳草boeahygrometrica （ bunge ） r
  4. In addition, the well retained stability and integrity of cell membrane of boea leaves might also be an important mechanism which make them resurrect well. by using mrna differential display, 5 desiccation sensitive cdnas, 52 desiccation - induced cdnas, 21 up - regulated cdnas, 14 down - regulated cdnas and 16 phosphate induced cdnas were obtained. the cloning, sequencing, homological blasting and northern blotting results of 5 desiccation - induced cdnas and 3 phosphate induced cdnas implied that signal transduction induced by desiccation, regulatory gene cascades and functional genes such as g protein, protein kinase, vp3 - and mad3 - like genes might be involved in dehydration in the resurrection plant boea hygrometrica

    對其中5個脫水特異誘導表達牛耳草光合作廠j的脫水保護和復甦機理的cdna （包括可能與復甦能力有關的cdna ）和3個磷酸鹽處理誘導表達的cdna進行克險測序、同源性探測和northern雜交檢測表明，牛耳草脫水過程中誘導表達的基因可能涉及到脫水脅迫的信號轉導「蛋白、蛋白激酶等） 、調節基因的級聯作用（ vp3 ， mad3樣基因等） 、結構基因產物調節細胞結構（包括細胞質膜）在脫水脅迫中的穩定性等。
  5. Obvious increases in asa, gsh and sucrose content during dehydration and steep declines in subsequent rehydration indicated that asa, as well as gsh and sucrose, might be involved in protection of dehydrated boea leaves, but not for rehydrated ones

    利用mrna差異顯示技術分離到牛耳草葉片脫水過程中5個脫水敏感的cdna 、 52個脫水特異誘導表達的cdna 、 21個脫水上調的cdna 、 14個脫水下調的cdna 、 16個磷酸鹽處理誘導表達的cdna 。
  6. The results of changes in photochemical activity parameters and chloroplast pigments in the present study indicated that xanthophylls cycle was induced in leaves of boea hygrometrica when they were dehydrated for 8 days under very weak light condition ( 3u mol. m - 2. s - 1 ), xanthophylls cycle may play a photoprotective role in dehydrated boea leaves

    為此本研究對牛耳草葉片光系統的光化學活性參數和葉黃素循環色素在脫水復甦過程中的變化進行了分析，結果表明，在極微弱的光強（ 3 mol m ~ （ - 2 ） s ~ （ - 1 ）下，脫水8天的牛耳草葉片誘導了葉黃素循環，葉黃素循環可能介導了牛耳草葉片脫水過程中的光保護作用。
