摘要: 以丰抗8号冬小麦幼苗为材料, 研究了水分胁迫下Ca2+和钙调素(CaM) 对叶片和根系过氧化物酶(POD) 同工酶的影响。结果表明, Ca2+/ CaM 作为第二信使参与了干旱信号的传导, 同时提高了POD同工酶活性、增强了小麦幼苗适应旱胁迫的能力, 并存在明显的剂量效应。在多种逆境信使系统中, POD 同工酶基因可能优先感受Ca2+/CaM 信使系统传导的干旱信号。小麦幼苗不同器官之间存在着干旱信号相互传递。与叶片相比, 根系POD 同工酶基因感受干旱信号的能力更强。

Abstract: The effects of Ca2+/CaM on growth and POD isoenzymes of winter wheat (cv.winter No.8 fengkang) seedlings under water stress were studied.The results showed that Ca2+/CaM,as the second messengers,played important roles in transducting drought signal.They not only increased the activities of POD isoenzymes,but also enhanced the adaptability of wheat seedings to drought.The effects were positive proportion to the Ca2+ concentration.Among drought signal systems,POD isoenzyme genes were possibly more sensitive to drought signal transfered by Ca2+/CaM messengers.The drought signal could be transducted among the different organs of wheat plant.Compared to leaves,POD isoenzyme genes in roots had higher adaptability to water stress.

Key words: Wheat, Water stress, Drought signal, Ca2+/ CaM, POD isoensyme
