香蕉是一种典型的呼吸跃变型果实,对其进行成熟的调控及机理的研究具有重要的理论和实践意义。Asr(脱落酸、胁迫、成熟诱导基因)是近年来从植物中发现的一类基因,据报道该基
,Main geological and mining factors affecting ground cracks induced by underground coal mining in Sh
As one of the largest coal-rich provinces in China,Shanxi has extensive underground coal-mining operations.These operations have caused numerous ground cracks a
Conventionally,mining industry relies on a deterministic view,where a unique mine plan is determined based on a single resource model.A major shortfall of this
目前DCS控制系统在国内外已广泛应用,是当今最流行的控制系统。但对于中小型装置(200点内),这类系统显得造价过于昂贵。板卡式DCS控制系统,解决在中小型装置使用计算机控制系
A quantitative analysis of the porosity,pore size distribution,and fractal dimensions of pores is significant for studying the pore structure characteristics of
在实验室条件下,研究了温度和盐度对条纹环沟藻(Gyrodinium instriatum)生长的影响.在28个温度(15 ~30℃)和盐度(0 ~35)组合中,条纹环沟藻在20℃和盐度25下生长最好.适宜生长温

乙烯应答因子(Ethylene Responsive Factors,ERFs)是植物特有的AP2/EREBP转录因子亚家族,参与植物的生长发育、新陈代谢、抗病及各种非生物胁迫的应答过程。植物的胁迫应答过程是一个多途径、多基因参与的复杂调控过程。发掘水稻抗逆功能候选基因并验证其功能,有助于完善水稻响应环境胁迫的分子调控网络和生理调控机制,为基因工程培育抗逆新品种提供基因资源。本研究前期采用基因芯片
