pollen-toxin 中文意思是什麼
-
So researchers have headed into nature themselves measuring the toxin in pollen from plots of gm corn estimating how much of it drifts onto plants such as milkweed and finally determining the exposure of butterfly and moth larvae to the protein
因此研究人員親下田野，到栽種基因改造作物的玉米田裡測量花粉中的毒素，估計有多少毒素會飄落到馬利筋之類的植物上，最後還需確定蛾蝶幼蟲的毒素接觸量。 -

It was found that plc activity was stimulated by both exogenous purified calmodulin and heterotrimeric g protein agonist cholera toxin. while, the stimulated effect on plc activity caused by exogenous calmodulin was inhibited by heterotrimeric g protein antagonist pertussis toxin, and plc antagonist u - 73122 inhibited the effect caused by cholera toxin. we also measure the free ca ~ ( 2 + ) level in germinating pollen grains, and found that exogenous purified calmodulin was able to increase the free ca ~ ( 2 + ) level, and their effects on ca ~ ( 2 + ) level were inhibited by u - 73122
實驗中，利用[ ~ 3h ] pip _ 2和花粉原生質體共同孵育的體系，檢測出了百合花粉細胞具有依賴pip _ 2的plc活性；利用該體系還檢測出外源鈣調素可促進plc的活性，其中10 ~ （ - 9 ） m的鈣調素可使plc的活性提高三倍；異三聚體g蛋白的激活劑ctx可以激活plc的活性，而其抑制劑ptx可明顯抑制plc活性；外源鈣調素的這種作用可以被ptx抑制；而plc抑制劑u - 73122抑制ctx對plc的激活效應。
