Sod2 from schizosaccharomyces pombe , which encodes a protein with homology to bacterial and mammalia na + / h + antiporters in plasma membrane and responses to efflux of na + , is an important gene i nvolving in homeostasis . though sod2 gene has been cloned , ectopic expression of sod2 in high plants has not been reported Sod2在裂殖酵母( schizosaccharomycespombe )中編碼位于質膜上的na ~ + h ~ +逆向轉運蛋白,控制na ~ +外排,對于保持裂殖酵母細胞的離子均衡非常重要。

By combining the information from the cdna sequences with functions of their homologs , we suggest that two kinds of hormones may play important roles during flower regeneration in a few ways : ( i ) proteolytic system of ubiqutin / 26s proteosome complex , ( ii ) actin - dependent vesicular cycling of auxin efflux carrier , ( iii ) regulating transcription of genes , ( iv ) phosphorylation and dephosphorylation 經過進一步的篩選,結合序列特征和同源基因的功能信息對這些基因功能進行了初步分析。認為兩種外源激素可能通過泛素26s蛋白酶體復合體對調節蛋白的降解機制,生長素運輸載體肌動蛋白依賴的小泡運輸,基因轉錄調節,磷酸化和去磷酸化等調節過程誘導風信子花分生組織的再生。

Lateral root development and gravitropism are regulated by polar auxin transport ( pat ) , and auxin efflux inhibitors ( aei ) inhibit lr growth and tropism . because of > the structural similarity to pat inhibitor npa , flavonoid has long been regarded as endogenous polar auxin transport inhibitor 生長素極性運輸( polarauxintransport , pat )對側根發生和根尖向地性起著重要的調節作用,添加外源生長素極性運輸抑制劑不僅抑制了側根發生,同時還使根尖喪失了向地性。

These mechanisms involve in the binding of heavy metals to cell wall , immobilization exclusion of the plasma membrane , efflux of these toxic metal ions , reduction of heavy metal transport , compartmentalization and metal chelation by tonoplast - located transporters , expression of more general stress response mechanisms such as stress proteins 這些機制包括重金屬離子與細胞壁的結合,限制重金屬離子透過細胞膜,重金屬離子或化合物的排出,重金屬在植物體內的轉移,重金屬的絡合與區隔化以及植物對脅迫的基本的反應機制如脅迫蛋白含量的變化等。

Rockburst is one of the difficult problems influencing colliery exploit safe . in recent years , utilize high pressure rotatory water efflux hole in coal seam , with high - efficient , energy - conservation , hole big , form regular , broken rock efficiency high advantage its , win the favor from vast engineers and technicians deeply 沖擊地壓一直是影響煤礦開采安全的一個難題,近年來,利用高壓旋轉水射流在煤層中鉆孔,以其高效、節能、鉆孔大、孔形規則、破巖效率高等優點,深受廣大工程技術人員的青睞。

Thou must now at last perceive of what universe thou art a part , and of what administrator of the universe thy existence is an efflux , and that a limit of time is fixed for thee , which if thou dost not use for clearing away the clouds from thy mind , it will go and thou wilt go , and it will never return 現在你至少要承認:你是宇宙的一個部分,對于宇宙的管理者而言,你的存在只是一種流出物,你生也有涯,如果你不把時間用于清除心靈上的塵垢,時間即將流逝,你也將消失,時間永不回轉。

The am fungus could obtain adequate carbon resources for itself , thus ensuring normal growth and metabolic activit y owing to the efflux of carbohydrate from the plasma membrane of the host root cortical cells to the interface of the symbiosis . thirdly , the structure and composition of the root cortex cellular plasma membrane kept good integrity and the leakage of carbohydrate maintained at low level when the plant obtained enough p and metabolizes normally . although enough carbohydrate was synthesized by plant , the am fungi could not obtain enough energy , resulting in inhibition of growth of the extraradical hyphae and decreased metabolic activity of the am fungi 由此,我們認為植物磷營養狀況調控菌根真菌生長和代謝活性的機制是:當植物處于嚴重缺磷脅迫時,不能合成足夠的碳水化合物供給自身生長的需要,也不能向真菌提供額外的碳水化合物,因而菌根真菌生長受阻,代謝活性較低;當植物中度缺磷時,根皮層細胞質膜的組成和結構不完整,通透性大,碳水化合物通過質膜向外的滲漏量大,菌根真菌因而獲得充足的碳源,保證真菌正常的生長和旺盛的代謝;當植物獲得足夠的磷而使體內磷營養代謝正常時,其細胞質膜組成和結構完整,碳水化合物的滲漏量保持在較低的水平,盡管此時植物合成了足夠的碳水化合物,但菌根真菌仍不能獲得足夠的能量,導致真菌生長受阻和代謝活性降低。

Taken together , a possible mechanism for sa improving al - tolerance of c . tora is proposed : treatments with sa promoted the al - induced increase in citrate efflux , and this resulted in the decreased accumulation of al in root tips , thereby causing a limited oxidative stress and root growth inhibition Sa緩解c . tora鋁毒害的可能機制:增加檸檬酸的分泌,降低根尖細胞內al的含量,減輕鋁誘導的氧化損傷,從而增強c . tora對鋁毒的抗性。

It was observed that the treatment of seedlings with 50 mol / l al for 12h led to a remarkable inhibition of root growth , which was accompanied by sufficient efflux of citrate out of roots and increase in the citrate content in the root tips 結果表明: al處理明顯抑制根的生長, 20 mol lal處理12h對c . tora根生長的抑制達52 . 4 。為了搞清al誘導c . tora根系檸檬酸分泌的生化與生理基礎,我們測定了與檸檬酸代謝直接有關的幾個酶的活性。

We also examined cs and aco activities , however , activities of both enzymes remained unaffected . these results indicated that sa - promotion of al - induced citrate efflux might be not correlated with increases in citrate production 但5 mol lsa對根尖內cs和aco活性并無顯著影響,說明sa增加鋁誘導的檸檬酸的分泌可能不是通過檸檬酸生物合成能力的提高或抑制其降解途徑而實現的。

Increased citrate efflux due to the sa treatment was associated with decreased inhibition of root growth and al content in root tips , suggesting that exogenous sa could confer al tolerance by increasing citrate efflux 由于sa增加al誘導的檸檬酸的分泌,因此明顯降低了根尖內al的含量,改善了鋁對根生長的抑制,表明sa可以通過增加檸檬酸的分泌來提高c . tora對鋁的抗性。

Activities of citrate synthase ( cs ) increased while those of aconitase ( aco ) decreased during the al stress . this might be the reason for the al - induced increase in citrate efflux 結果顯示,介質中50 mol lal能顯著提高根尖檸檬酸合酶( citratesynthase , cs )的活性,同時伴隨著檸檬酸含量的升高。
