As the cornerstone mission of the fourth phase of the Chinese Lunar Exploration Program, Chang'E-7(CE-7) was officially approved, and implementation started in 2022, including a main probe and a communication relay satellite. The main probe, consisting of an orbiter, a lander, a rover and a mini-flying probe, is scheduled to be launched in 2026. The lander will land on Shackleton crater's illuminated rim near the lunar south pole, along with the rover and mini-flying probe. The relay satellite(named Queqiao-2) will be launched in February 2024 as an independent mission to support relay communication during scientific exploration undertaken by Chang'E-4, the upcoming Chang'E-6 in 2024 and subsequent lunar *** CE-7 mission is mainly aimed at scientific and resource exploration of the lunar south pole. We present CE-7's scientific objectives, the scientific payloads configuration and the main functions for each scientific payload with its key technical specifications.

WRKY转录因子基因家族是植物特有的转录因子,在防御中起着重要作用。通过生物信息学分析,本研究在古四倍体大豆(Glycine max)基因组中找到一对同源性高达93%的WRKY33同源基因,并将其命名为GmWRKY33B。从GmWRKY33B的两个同源基因保守区域选取一个315bp片段构建至菜豆豆荚斑驳病毒(bean pod mosaic virus,BPMV)沉默载体(BPMV-VIGS)上,以期同时沉默上述2个GmWRKY33B基因。结果表明,同时沉默2个GmWRKY33B基因并不显著改变沉默植株的表型,但却显著降低了大豆对大豆斑点病菌以及大豆花叶病毒的抗性,说明GmWRKY33B在大豆免疫反应中起正调控作用。激酶分析表明,GmWRKY33B沉默植株中flg22诱导的GmMPK6的磷酸化水平较空载体BPMV-0植株显著降低,说明GmWRKY33B可以通过调控GmMPK6的激酶活性而参与大豆的免疫反应。抗毒素为大豆中主要起防御作用的植保素,而大豆异黄酮类特异性异戊烯基转移酶(prenyltransferase,PT)基因家族是参与大豆抗毒素生物合成的主要基因,许多PT基因启动子区含有与WRKY特异性结合的W-box序列。在丁香假单胞菌pv.甘氨酸(Pseudomonas syringae ***,Psg)侵染条件下,4个PT基因的表达水平在沉默株系中显著降低,说明GmWRKY33B参与PT基因的转录激活。综上所述,GmWRKY33B通过调控GmMPK6的激活以及调控大豆抗毒素生物合成途径中关键酶编码基因的表达而参与免疫反应。

右江盆地是全球仅次于美国内华达地区的第二大卡林型金矿床集中分布区。由于成矿时代的不确定性,盆地内卡林型金矿床的成矿动力学背景一直不清。为准确确定这些金矿床的成矿时代,近四十年来国内外矿床学家进行了孜孜不倦的探索,从早期以石英裂变径迹和流体包裹体Rb-Sr等时线法为代表的定年,到中期以硫化物Re-Os等时线法为代表的单矿物溶样法定年,再到最新以热液金红石、独居石和磷灰石U-Th-Pb法为代表的微区原位定年,其定年对象和方法见证了同位素地质年代学的发展历程。现已基本明确,右江盆地主要发育两期卡林型金矿成矿作用,分别为215~200 Ma和155~140 Ma,相当于印支期和燕山期,其动力学背景分别对应于印支-华南-华北地块碰撞后的印支期陆内造山过程以及燕山期软流圈上涌诱发的岩石圈伸展作用。

自噬在生物体细胞内物质循环利用及适应各种胁迫方面起着重要作用。然而,对大豆自噬途径的研究鲜有报道。本研究利用大豆豆荚斑驳病毒(bean pod mottle virus,BPMV)介导的基因沉默技术,对大豆自噬相关基因5(autophagy-related gene 5,ATG5)同源基因进行沉默。结果发现,经暗处理的GmATG5沉默植株叶片上积累过量的ATG8蛋白,说明自噬降解途径受损;与自噬途径受损相一致,暗处理的GmATG5沉默植株叶片出现明显的衰老加速的表型;另外,GmATG5沉默植株叶片中活性氧(reactive oxygen species,ROS)的积累量以及水杨酸含量显著增加,说明沉默GmATG5激活了免疫反应;抗病性分析表明,GmATG5沉默植株对大豆斑点病菌(Pseudomonas syringae ***,Psg)的抗性较空载体对照植株显著增强,但该抗病性的增强并不依赖于丝裂原活化蛋白激酶(mitogen-activated protein kinase,MAPK)途径的激活。

为了实现对DCS组态下装的可控,将不可见的逻辑转化为可实现的设备真实反映,研发了一项能在模拟机上实现组态真实验证的方法。然而由于模拟机的特殊性,现场真实数据无法直接安装于模拟机,需要人为修改一层组态为模拟机所允许的匹配关系,这将耗费大量人力,因此提出一款适用于M310机型模拟机且可快速自动批量更改DCS一层脚本的软件设计思路,旨在提升DCS数据验证的可靠性,同时降低人为修改带来的偏差。
