前天我在facebook上看到研究所老闆的頁面,加入老闆的朋友名單內,隔天就收到他的回覆:要mail一份reprint給我,我心想是什麼reprint啊??剛剛收e-mail信件發現老闆寄的信件,一打開內容,原來老闆所謂的reprint竟然是PHOTOSYNTHETICA期刊上我的paper,老闆將我碩士論文寫成期刊文章寄到PHOTOSYNTHETICA,被他們接受刊出了,真是興奮!是我今年生日最好的禮物了

*以下是我的paper之摘要~~~

Abstract

The common bean (Phaseolus vulgaris L.) is sensitive to high temperature, while an ecologically contrasting species (Phaseolus acutifolius A. Gray) is cultivated successfully in hot environments. In this study, the two bean species were respectively acclimated to a control temperature of 25 °C and a moderately elevated temperature of 35 °C in order to compare the thermotolerance capabilities of their photosynthetic light reactions. Growth at 35 °C appeared to have no obvious adverse effect on the photosynthetic activities of the two beans, but changed their thermotolerance. After a short period of heat shock (40 °C for up to 4 h), the photosynthetic activities of 25 °C-grown P. vulgaris declined more severely than those of P. acutifolius grown at 25 °C, implying that the basal thermotolerance of P. vulgaris is inferior to that of P. acutifolius. But after acclimating to 35 °C, the thermotolerances of the two species were both greatly enhanced to about the same level, clearly demonstrating the induction of acquired thermotolerance in their chloroplasts, and P. vulgaris could be as good as P. acutifolius. Temperature acclimation also changed plants’ resistance to photoinhibition in a manner similar to those toward heat stress. In addition, acquisition of tolerance to heat and strong irradiance would reduce the dependency of the two beans on xanthophyll pigments to dissipate heat, and also seemed irrelevant to the agents with antioxidant activities such as SOD.
