非洲Okavango裂谷是东非裂谷系最年轻且仍处于发育初期阶段的裂谷,研究其地下结构及变形特征有助于深入了解东非裂谷系裂解初期结构构造特征,并进一步完善对裂谷系裂解动力学机制的认识.本文收集Okavango裂谷区域内41个宽频地震台站的连续波形数据,采用背景噪声技术获取Rayleigh和Love波相速度频散数据,进一步通过直接成像技术获得研究区地下50 km深度范围内的三维剪切波速度和径向各向异性结构.剪切波速度和径向各向异性结果显示,Okavango裂谷的中地壳具有低速和负径向各向异性(V_(Sh)h)>V_(SV))的特征,结合前人资料,本文认为Okavango裂谷的发育可能是在先存构造薄弱带上由板内相对运动所提供的水平方向构造应力诱发的.此外,我们的结果还显示,在邻区Zimbabwe克拉通西南部,中、下地壳呈现出负径向各向异性,这一观测支持Okavango岩墙群侵入地壳导致该区域地壳增厚的认识.

印度-澳大利亚板块沿着苏门答腊海沟对巽他板块的俯冲在苏门答腊岛的西侧造就了大量的活动火山,以及包括引发2004印度洋大海啸的Mw 9.1-9.3级大地震在内的灾害性极强的地震活动。此海啸袭卷周边12个国家和地区,造成至少23万人丧生或失踪。自2000年以来,此区域发生了11个震级≥7.5的大地震。印度-澳大利亚板块对巽他板块的俯冲也造就了多巴火山,其被认为是陆地最大的第四纪火山口,最近发生的一次喷发约在74000年前,此次喷发释放出了约2800-5300立方千米的火山物质,被认为对整个地球的生物圈有重大影响。全球定位系统和绝对板块运动速度建模显示印度-澳大利亚板块对巽他板块的俯冲速度约为64mm/yr,方向为正北偏东40度。

Maize(Zea mays)endosperm is an important food source for humans and *** addition,it is considered an excellent model for research on seed development because of its relatively large size for both embryo and endosperm compared to those of other crop species,such as rice(Oryza sativa)and wheat(Triticum aestivum).After double fertilization,early maize endosperm development includes three stages:(i)a multinucleate coenocyte stage;(i)a cellularization stage,in which the cellular endosperm is formed;and(ii)a stage of differentiation into distinct *** early differentiation,four major cell types with specific functions differentiate within the endosperm:starchy endosperm,aleurone layer,basal endosperm transfer layer(BETL),and embryo surrounding *** subaleurone,conducting zone,basal intermediate zone,and endosperm adjacent to scutellum arise in late differentiation(Sabelli and Larkins 2009).After the main cell types are established,maize endosperm undergoes intensive cell proliferation,which marks the transition to the endosperm-filling *** the endosperm-flling stage,the maternal sucrose products are transported to seeds through the BETL region,where they will act as the main carbon substrate for storage products such as starch and proteins(Chen et al.,2023).In fact,the endosperm of maize seeds accounts for approximately 90%of the total grain weight,serving as an important nutrient reservoir(Flint-Garcia et al.,2009).
