| dc.description.abstract | 本研究以生長兩天的大豆白化幼苗為材料， 探討植物幼苗及粒腺體呼吸作用耐熱性的獲得．其中包括檢查植物幼苗的呼吸速率，粒腺體的呼吸活性，及其對鈣離子的吸收能力．同時，在TEM下觀察大豆幼苗根尖細胞，和分離出粒腺體的顯微構造． 實驗結果顯示，無論是植物幼苗或是分離出的粒腺體，都有形成耐熱性的能力．大豆幼苗在45℃(2hr)下呼吸速率極低，但40℃(2hr)仍有正常的呼吸速率．若在45℃前先給與40℃(2hr)處理，則呼吸速率可提高一倍，且在28℃下恢復的能力極佳．分離出的粒腺體在42.5℃的水浴中幾乎沒有呼吸活性，但若事先給與植物幼苗38℃(2hr) - 42.5℃(0.5hr)的處理，則可使其在42.5℃的水浴中仍具有呼吸活性．若在38℃(2hr) - 42.5℃(0.5hr)處理後再將幼苗種回28℃溫度下4小時，此時，粒腺體又喪失了在42.5℃水浴中的呼吸活性． TEM下觀查的情形，也有類似的結果．45℃(2hr)處理後的大豆幼苗根間的細胞，其中的微細構造完全瓦解，但在40℃(2hr)則保存了幾乎所有的完整性，若45℃前給與—40℃(2hr)的處理，細胞內遭受破壞的情形不若直接以45℃處理的嚴重，且比較45℃(2hr)及40℃(2hr)-45℃(2hr)兩種處理之後在28℃下恢復的情形，只有後者顯示了極佳的恢復潛能，並在28℃(12hr)之後，細胞內的膜狀構造就幾乎完全恢復原先的完整狀態． 無論在生體內(in vivo)或試管中(in vitro)的研究結果，均支持了植物細胞若要獲得耐熱性(thermotolerance)，首先細胞內要先累積足夠量的HSPs(40℃(2hr)或38℃(2hr))，其次，這些HSPs要選擇性地結合至膜狀胞器上(45℃(2hr)或42.5℃(0.5hr))，以建立各個胞器，整個細胞，以至整株植物體的耐熱性． | zh_TW |
| dc.description.abstract | Two-day-old etiolated soybean seedlings were used to study the thermotolerance of their respiration functions including seedling respiration rate, isolated mitochondria 02 consumption and Ca2+ uptake activity. Also, we investigated their ultrastructures under TEM. Following the elevation of temperature, the respiration rate of seedlings decreased, and it was not possible to recover after a 45℃(2h) treatment. Whereas, a 40℃(2h) treatment or 40℃ (2h) before shifted to 45℃(2h) had potential to recover when grown in 28℃. Mitochondria isolated which had been subjected to various heat shock(HS) treatments i.e., A.28℃(2h), B.38℃(2h), C.38℃(2h) - 42.5℃(30'), and D.38℃(2h) - 42.5℃(30') - 28℃(4h), were monitored for 02 consumption using an Oxygen electrode. Mitochondria isolated after all four HS treatments were active in 02 consumption at 28℃ in response to succinate and ADP (derived P/O ratios were 1.4, 1.3, 1.2 and 1.2, respectively). However, only mitochondria isolated after treatment C. were active in O2 uptake at 42.5℃ (derived P/O ratio was 1.1). Our data demonstrate that association of HS proteins with mitochondria by treatment C. enables them to continue to function at 42.5℃ (i.e., they become thermotolerant). Mitochondria from which associated HS proteins were allowed to dissociate (treatment D) showed no significant O2 consumption at 42.5℃. Isolated mitochondria from treatment C. and treatment A. were compared by TEM. They appeared to be very similar, and no significant ultrastructural differences were noted. | en |
