    Abstract: 甘藍(Brassica oleracea L. var. capitata L.),是世界重要蔬菜之一,目前是臺灣大宗栽培及消費市場不可或缺的葉菜。臺灣夏季炎熱多雨,使甘藍面臨高溫與淹水逆境,影響夏季生產與品質甚鉅。因此改善甘藍對於高溫淹水逆境之耐受性,一直是專家學者努力的目標。本試驗以甘藍耐熱、耐濕性高品種’嗄嗄叫’與耐熱、耐濕性低品種’迷你’為試驗材料,在45天苗期給予以常溫22℃和高溫40℃之淹水與不淹水處理,處理時間包括0、6、12、24、48、72小時,於各時間點調查植物生長性狀,測量葉片葉綠螢光與氣孔導度,之後以全自動二維蛋白快速層析分離系統(Proteome LabTM PF-2D)與Matrix assisted laser desorption/ionization-time of flight mass spectrometer (MALDI-TOF MS),分析辨認不同處理下的葉片蛋白質。’迷你’在高溫淹水處理下,植株地上部鮮重與乾重變化、病徵、葉綠素螢光下降程度與氣孔導度變化皆顯著較’嗄嗄叫’強烈。根據逆境處理植株生理數據與外觀,選擇高溫淹水處理6、12與24小時之植株葉片,進行蛋白質體分析。’迷你’於高溫淹水6、12與24小時處理下,分別發現5、9與20個蛋白質表現量有差異的高峰,與homocysteine methyltransferase、Sulfite reductase [NADPH] hemoprotein beta-component、Isoleucyl-tRNA synthetase、ATP synthase subunit beta、ribulose 1,5-bisphosphate carboxylase/ oxygenase large chain、Ribulose bisphosphate carboxylase large chain precursor、rubisco ssu precursor、Oxygen-evolving enhancer protein 1-1, chloroplast precursor、Oxygen-evolving enhancer protein 1-2, chloroplast precursor、ATP synthase subunit beta、periplasmic binding protein/LacI transcriptional regulator、Cysteine sulfinate desulfinase/cysteine desulfurase and related enzymes、L-lactate dehydrogenase與glycoside hydrolase, family 3 domain protein等蛋白質相似。而’嗄嗄叫’於高溫淹水6、12與24小時處理下,分別發現7、20與26個蛋白質表現量有差異的高峰,與Ribulose bisphosphate carboxylase large chain precursor 、Cysteine desulfurase、ATP synthase subunit beta、Probable fucosyltransferase 8、putative hydratase/decarboxylase、V-type ATP synthase alpha chain、Oxygen-evolving enhancer protein 1-1, chloroplast precursor、Oxygen-evolving enhancer protein 1-2, chloroplast precursor、Heat shock 70 kDa protein、Serine/threonine protein phosphatase 7 inactive homolog、Cysteinyl-tRNA synthetase、Galectin-2與Flagellin A等蛋白質相似。這些蛋白質分別與光合作用、蛋白質生合成、胺基酸轉譯、熱穩定蛋白、醣類代謝、ATP合成、細胞壁分解及訊息傳導有關。
