| 1 | Reversible Histone H2B Monoubiquitination Fine-Tunes Abscisic Acid Signaling and Drought Response in Rice显示文摘Histone H2B monoubiquitination (H2Bub1) plays important roles in several physiological and developmental processes, but its roles in the regulation of plant stress responses remain elusive. Here, we report that H2Bub1 is crucially involved in abscisic acid (ABA) signaling and drought response in rice. We found that rice HISTONE MONOUBIQUITINATION2 (OsHUB2), an E3 ligase for H2Bub1, in teracted with OsbZIP46, a key transcription factor regulating ABA signaling and drought response in rice. Genetic analyses suggest that OsHUB2, upregulated by drought and ABA, positively modulates ABA sensitivity and drought resistance. The H2Bub1 levels were in creased in the target genes of OsbZIP46 under the drought stress and ABA treat- merits, which were positively correlated with their increased expression levels. Interestingly, MODD, a reported suppressor of ABA signaling and drought resistance by mediating OsbZIP46 deactivation and degradation, could reduce the H2Bub1 levels in the target genes of OsbZIP46 by recruiting a putative deubiquitinase OsOTLD1 . Suppression of OsOTLD1in vivo resulted in increased H2Bub1 levels and expression of OsbZIP46 target genes. Collectively, these fin dings established an elaborate mecha nism of histone monoubiquitination in the fine-turning of ABA signaling and drought response by balancing H2Bub1 deposition and removal. | Siqi Ma Ning Tang Xu Li Yongjun Xie Denghao Xiang Jie Fu Jianqiang Shen Jun Yang Haifu Tu Xianghua Li Honghong Hu Lizhong Xiong | 2019 | Molecular Plant2019，12，2： | 7 |
| 2 | Tuning the shell thickness of core-shell α-Fe_(2)O_(3)@SiO_(2) nanoparticles to promote microwave absorption显示文摘Various advanced microwave absorbing materials have been developed for reducing/avoiding the harm of microwave radiation.Among them,core-shell structural nanomaterials have been widely fabricated for microwave absorption.However,the“structure-performance”relationship between shell thickness and microwave absorption performance is rarely reported.In this paper,we first explored the“structure-performance”relationship between shell thickness and microwave absorption performance,based on the core-shellα-Fe_(2)O_(3)@SiO_(2)nanoparticles with a constantα-Fe_(2)O_(3)-core size and changeable SiO_(2)-shell thickness.With increasing the SiO_(2)-shell thickness,the microwave absorption ability first increased,then decreased.Under a proper SiO_(2)-shell thickness of 35 nm,α-Fe_(2)O_(3)@SiO_(2)sample achieved the strongest microwave absorbing ability with a reflection loss minimum value of-4.3 d B,better than that of pureα-Fe_(2)O_(3)(-3.8 dB).This enhanced microwave absorption performance was mainly derived from the di-electric loss.Although the absolute value of the reflection loss was relatively low(-4.3 d B),this study shed an important reference on designing next-generation advanced iron oxide-based materials for mi-crowave absorption. | Honghong Fu Yue Guo Jian Yu Zhen Shen Jie Zhao Yu Xie Yun Ling Sheng Ouyang Shiqi Li Wei Zhang | 2022 | Chinese Chemical Letters2022，33，2： | 0 |
