Under high osmotic shock , the size of the cells obviously shrink , so did the chloroplasts , mitochondria and golgi bodies , etc . the membranes of these organelles partially melt with that of endoplasmic reticulum , which makes its surface area increase 在高滲震動下,細(xì)胞體積明顯變小,胞內(nèi)細(xì)胞器如葉綠體、線立體、高爾基體等的體積也相應(yīng)變小,這些細(xì)胞器的膜部分融合至內(nèi)質(zhì)網(wǎng)膜中,使內(nèi)質(zhì)網(wǎng)的表面積增大。
By using inverted microscope , it was observed that dunaliella salina of different growth stages after the high osmotic shocks can live in the medium with nacl concentration between 0 . 1m and 5 . 0m , but its growth status and period showed differently . the optimal concentration for the growth of dunaliella salina was 0 . 5 - 1 . 5m , and this organism could stand a variety range of osmotic shock . enolase gene , the anti - adversity gene of d . salina , was cloned by modified degenerate pcr technique 通過倒置顯微鏡觀察生長在不同鹽濃度,不同生長時期,以及經(jīng)不同滲透壓震動的鹽藻,四川大學(xué)博士學(xué)位論文發(fā)現(xiàn)其在o . im一5 . omnaci培養(yǎng)基中均能正常生長,但其生活狀態(tài)及生長周期有所不同,其最適生長naci濃度為0 . 5一1 . 5m ,還能適應(yīng)各種高滲及低滲震動。
百科解釋
Osmotic shock or osmotic stress is a sudden change in the solute concentration around a cell, causing a rapid change in the movement of water across its cell membrane. Under conditions of high concentrations of either salts, substrates or any solute in the supernatant, water is drawn out of the cells through osmosis.
