Protein kinases are major players in various signal transduction pathways. Understanding the molecular mechanisms behind plant responses to biotic and abiotic stresses has become critical for developing and breeding climate-resilient crops. In this review,we summarize recent progress on understanding plant drought, salt, and cold stress responses, with a focus on signal perception and transduction by different protein kinases, especially sucrose nonfermenting1(SNF1)-related protein kinases(Sn RKs),mitogen-activated protein kinase(MAPK) cascades,calcium-dependent protein kinases(CDPKs/CPKs),and receptor-like kinases(RLKs). We also discuss future challenges in these research fields.

The mechanisms that balance plant growth and stress responses are poorly understood, but they appear to involve abscisic acid(ABA) signaling mediated by protein kinases. Here, to explore these mechanisms, we examined the responses of Arabidopsis thaliana protein kinase mutants to ABA treatment. We found that mutants of BRASSINOSTEROID INSENSITIVE 1-ASSOCIATED RECEPTOR KINASE 1(BAK1) were hypersensitive to the effects of ABA on both seed germination and primary root growth. The kinase OPEN STOMATA 1(OST1) was more highly activated by ABA in bak1 mutant than the wild type. BAK1 was not activated by ABA treatment in the dominant negative mutant abi1-1 or the pyr1 pyl4 pyl5 pyl8 quadruple mutant, but it was more highly activated by this treatment in the abi1-2 abi2-2 hab1-1 loss-of-function triple mutant than the wild type. BAK1 phosphorylates OST1 T146 and inhibits its activity. Genetic analyses suggested that BAK1 acts at or upstream of core components in the ABA signaling pathway, including PYLs, PP2 Cs,and Sn RK2 s, during seed germination and primary root growth. Although the upstream brassinosteroid(BR) signaling components BAK1 and BR INSENSITIVE 1(BRI1) positively regulate ABAinduced stomatal closure, mutations affecting downstream components of BR signaling, including BRASSINOSTEROID-SIGNALING KINASEs(BSKs)and BRASSINOSTEROID-INSENSITIVE 2(BIN2), did not affect ABA-mediated stomatal movement. Thus,our study uncovered an important role of BAK1 in negatively regulating ABA signaling during seed germination and primary root growth, but positively modulating ABA-induced stomatal closure, thus optimizing the plant growth under drought stress.

马克思恩格斯文明观意涵丰富,主要体现在五个维度。其一,作为生产方式的文明。农业和工业的生产方式分别造就了农业的和工业的文明形式。资本文明是一种典型的工业文明,但更高级的生产方式及文明形态构成人类历史的真正出路。其二,作为社会形态的文明。人类社会经历不同发展形态,具有与之相应的文明类型。“自由个性”是人类社会的高级阶段,真正的普遍的文明在此阶段呈现。其三,作为时代历史阶段的文明。文明是区分不同时代的鲜明标识,代表时代历史的发展深度。文明时代与野蛮时代、蒙昧时代区别开来。其四,作为历史演进趋势的文明。人类历史不断由低级阶段步入高级阶段,文明不断从资本文明挺进社会主义与共产主义的高级文明。其五,作为人的生存状态的文明。文明的本质在于人的进步。人的理想生存状态是实现“人的生命活动的性质”,全面占有自己的本质。

党性关乎立场,关乎一个政党的道路走向,甚至关乎一个政党的最终命运。党性概念构成马克思主义政党学说的重要组成部分。党性概念意涵深刻,作为一种政治概念,表明无产阶级政党的鲜明阶级立场和明确价值取向;作为一种哲学概念,哲学上的党性问题决定着哲学立场的划分,进而规定一个政党的属性和定位;作为一种实践性概念,表征着无产阶级政党的革命实践问题。党性代表着党的根本属性,是试炼无产阶级政党的试金石。新时期,加强党的建设,首要的是坚持马克思主义党性原则,不断强化党的思想建设、党风建设、党纪建设,更好地保持党的先进性和纯洁性。

为了定量分析各种水泥生产工艺造成的环境影响以及工艺替代时可能造成的环境问题转移,采用生命周期评价(Life Cycle Assessment,LCA)方法,建立了大型、中型、小型新型干法、传统立窑、新型半干法(JT窑)5种典型水泥生产工艺从原材料开采到熟料生产的生命周期模型,对比分析了以上工艺生命周期过程中能耗、温室效应、酸化、可吸入无机物等主要环境影响类型的差异,提出并计算了大型新型干法替代其他工艺时的"平衡运输距离",并推导了其一般表达式.结果表明,由于大型新型干法工艺氮氧化物排放较多,使得工艺替代时可能伴随着环境问题从能耗、温室效应向酸化、可吸入无机物等影响类型转移;同时,由于产能增加,大型新型干法工艺也可能导致环境影响从生产阶段向运输阶段转移.从本文的案例研究可以看出,LCA方法可以定量分析不同环境影响类型之间和不同生命周期阶段之间的环境问题转移,能为技术评价和相关政策制定及实现全社会节能减排目标提供科学的依据与建议.
