Differential expression of heat shock protein genes in preconditioning
for photosynthetic acclimation in water-stressed loblolly pine.
火炬松在缺水狀態下光馴化預處理後熱休克蛋白基因的差異表現
Heat shock proteins (HSPs) are induced not only under heat stress conditions but also under other environmental stresses such as water stress.
熱休克蛋白（HSPs）的誘發，不是只有在熱逆境的環境下，還有其他的環境逆境，例如水份逆境。
In plants, HSPs families are larger than those of other eukaryotes.
在植物中，熱休克蛋白的家族比其他真核生物大。
In order to elucidate a possible connection between HSP expression and photosynthetic acclimation or conditioning, we conducted a water stress experiment in loblolly pine (Pinus taeda L.) seedlings involving progressive treatment consisting of one cycle of mild stress (－1 MPa) followed by two cycles of severe stress (－1.7 MPa).
為了闡明熱休克蛋白的表達可能與光合馴化或環境之間有相關，我們進行了一項火炬松水分逆境的實驗（火炬松）幼苗逐漸進入一週期包含輕度逆境的處理（－1MPa），接著是兩個週期的重度逆境（－1.7MPa）。
Net photosynthesis was measured at each stress level.
淨光合作用是在測量每個逆境水平。
Photosynthetic acclimation occurred in the progressive treatment after the first cycle, but not in the severe treatment, suggesting that a cycle of mild stress conditioned the trees to adapt to a more severe stress.
光合馴化在第一個週期的處理後逐漸發生，但不是在重度處理中，這顯示在輕度逆境環境一週期後的樹木，能適應更嚴峻的逆境。
Real time results indicated specific patterns in needles in the expression of HSP70, HSP90 and sHSP genes for each treatment, both at maximum stress and at recovery.
熱休克蛋白70，熱休克蛋白90和小熱休克蛋白每次同時在最大境逆和在恢復處理狀態下基因的表現，結果經由指針即時顯示在特定的圖案內。
We identified a pine homolog to GRP94 (ER resident HSP90) that was induced after rehydration coincident with acclimation.
我們確定了松樹的同源性，糖調節蛋白94（（ER）內質網內的熱休克蛋白90）在誘導後一致再水合與馴化。
Further analysis of the promoter region of the pine GRP94 showed putative cis-elements associated with water stress and rehydration, corresponding to the expression pattern observed in our experiment.
進一步分析啟動子區的松樹糖調節蛋白94顯示順式作用元件與水壓和再水合有相關，在我們的實驗中觀察其表現的方式一致(Vásquez-Robinet et al., 2010)。
