The correlation of the scaled energy,e?=Es/M0,versus earthquake magnitude,Ms,is studied based on two models:(1)Model 1 based on the use of the time function of the average displacements,with a x-2source spectrum,across a fault plane;and(2)Model 2 based

侧根是植物根系的重要组成部分,其发生和发育受到内源植物激素和外界环境因素的共同影响。生长素在侧根发生起始、侧根原基的发育和侧根突破母体表皮等阶段均发挥关键作用。研究侧根的发育和形态解剖结构以及信号调控途径等,都具有重要的理论和实践意义。本文结合近年来的研究进展,综述了拟南芥和水稻侧根发育的详细过程和影响因素,重点关注生长素在侧根原基发生和发育过程中的作用。

干旱、盐渍、低温等逆境胁迫会严重影响植物的正常生长发育,导致植物的许多响应基因被诱导表达,其蛋白质产物能够保护植物免受胁迫的伤害。色氨酸-天冬氨酸重复序列蛋白(WD40蛋白)在植物中广泛存在,参与植物体内众多代谢反应的调控,如花的发育、开花、花青素的生物合成、激素响应、渗透胁迫等。WD40蛋白含有40~60个氨基酸的保守的WD重复序列,其C末端为色氨酸-天冬氨酸(Trp-Asp,WD),形成一个β

CONSTANS(CO)基因是生物钟和开花时间基因之间监测日照长度的重要元件,在光周期途径中发挥核心功能。CO可以整合光信号和生物钟信号,诱导开花途径整合子FLOWERING LOCUS T(FT)和SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1(SOC1)的表达,进而促进植株开花。本文综述CO基因的开花调控机制,并结合CO基因的研究现状展望了其未来的研究方向

植物就像一个糖罐子。研究者通过研究植物树液中的甜味得出了这一结果。树液把植物叶子上的糖分输送到植物其他部位,例如根部,将糖分储存进树液中时。植物面临一个棘手的局面:如果树液中糖分过多,将会太浓以至于难以轻易地流动;但是如果树液中糖分过少,将造成低效的输送。
