PHYTON-INTERNATIONAL JOURNAL OF EXPERIMENTAL BOTANY 2024年第8期93卷 1839-1850页

Genes in the glycogen synthase kinase 3 (GSK3) family are essential in regulating plant response to stressful conditions. This study employed bioinformatics to uncover the GSK3 gene family from the sunflower genome database. The expressions of GSK3 genes in different tissues and stress treatments, such as salt, drought, and cold, were assessed using transcriptome sequencing and quantitative real-time PCR (qRT-PCR). The study results revealed that the 12 GSK3 genes of sunflower, belonging to four classes (Classes I-IV), contained the GSK3 kinase domain and 11-13 exons. The majority of GSK3 genes were highly expressed in the leaf axil and flower, while their expression levels were relatively lower in the leaf. As a result of salt stress, six of the GSK3 genes (HaSK11, HaSK22, HaSK23, HaSK32, HaSK33, and HaSK41) displayed a notable increase in expression, while HaSK14 and HaSK21 experienced a significant decrease. With regard to drought stress, five of the GSK3 genes (HaSK11, HaSK13, HaSK21, HaSK22, and HaSK33) experienced a remarkable rise in expression. When exposed to cold stress, seven of the GSK3 genes (HaSK11, HaSK12, HaSK13, HaSK32, HaSK33, HaSK41, and HaSK42) showed a substantial increase, whereas HaSK21 and HaSK23 had a sharp decline. This research is of great importance in understanding the abiotic resistance mechanism of sunflowers and developing new varieties with improved stress resistance.

研究有效波高（Significant Wave Height,SWH）的特征对海洋灾害预警和海洋生产安全具有重要意义。中法海洋卫星（China-France Oceanography SATellite,CFOSAT）上搭载的世界领先的SWIM波谱仪能够测量全球范围内的海浪参数。已有大量研究对CFOSAT海浪产品在全球范围内进行评估，然而对区域的研究相对较少。本研究采用中国近海39个浮标的海浪数据来评估2020年SWIM二级产品的数据质量，空间和时间匹配窗口分别为100km和5min。结果表明：经过对陆地干扰施加不同程度的控制，SWIM有效波高产品具有较高的精度。在完全去除陆地干扰后，星下点SWH与浮标观测的一致性较高，均方根误差为0.346 m，相关系数为0.943，散射因子为0.182。SWIM数据与浮标观测数据之间的总体差异随着SWH的增加而增大。6°、8°、10°入射角波束和合成波束SWH与浮标观测一致性良好，但精度略低于星下点SWH。这些发现都有力地证明SWIM二级产品在中国近海具有很高的可信度。

健康责任是指主体为了客体健康承担的责任。评价健康责任的伦理框架由健康价值、自主选择、无害他人、健康公平、互惠共济和职业责任六项基本原则构成。个人对自身健康的责任有限,并且责任内容应该仅限于指导个人采取健康促进行动,不应包括对个体不利健康行为进行追责。明确健康责任的根本目的是促进责任主体做出负责任的行动,从而促进个体和群体的健康。建议在使用伦理的话语讨论健康责任议题时,关注信息对实现公共卫生目标的可能影响。

通过构建微宇宙实验模拟了为期52 d的蓝藻生长与消亡过程,利用薄膜扩散梯度技术(DGT)分析了蓝藻生消过程沉积物-水界面(SWI)有效态磷、铁、硫的分布及其扩散通量变化.结果表明,实验周期内加藻组上覆水的溶解氧(DO)和pH均高于对照组,藻类生长和消亡显著改变了界面理化性质.蓝藻萌发期(1~4 d)和快速生长期(15~19 d)SWI有效态磷和有效态铁显著正相关表明,沉积物磷的释放主要受控于铁磷的还原.蓝藻快速生长阶段(15~19 d),有效态铁、有效态硫扩散通量的同步升高指示铁、硫循环耦合了内源磷的释放;此外,沉积物碱性磷酸酶活性(APA)的上升和烧失量(LOI)的下降指示了有机磷矿化释放的另一途径.蓝藻快速衰亡阶段(23 d),藻类有机质降解磷释放导致了沉积物有效态磷和铁的解耦.蓝藻衰亡后期(41~52 d),硫酸盐还原介导的磷释放减弱,有效态磷和有效态铁的显著正相关指示沉积物铁磷的还原再次成为磷释放的主要机制,但释放水平显著降低.本研究表明,蓝藻生消显著影响了沉积物-水界面铁、硫、磷耦合循环,对认识湖泊内源污染释放规律与富营养化治理具有科学参考价值.

HY-2 has been launched by China on August 16, 2011 which assembles multi-microwave remote sensing payloads in a body and has the ability of monitoring ocean dynamic environments. The HY-2 satellite data need to be calibrated and validated before being put into use. Based on the in-situ buoys from the Nation- al Data Buoy Center （NDBC）, Ku-band significant wave heights （SWH, hs） of HY-2 altimeter are validated. Eleven months of HY-2 altimeter Level 2 products data are chose from October 1, 2011 to August 29, 2012. Using NDBC 60 buoys yield 902 collocations for HY-2 by adopting collocation criteria of 30 min for tempo- ral window and 50 km for a spatial window. An overall RMS difference of the SWH between HY-2 and buoy data is 0.297 m. A correlation coefficient between these is 0.964. An ordinary least squares （OLS） regression is performed with the buoy data as an independent variable and the altimeter data as a dependent vari- able. The regression equation of hs is hs （HY-2）=0.891 × hs （NDBC）＋0.022. In addition, 2016 collocations are matched with temporal window of 30 rain at the crossing points of HY-2 and Jason-2 orbits. RMS difference of Ku-band SWH between the two data sets is 0.452 m.
