| 1 | Status and development of high-power laser facilities at the NLHPLP显示文摘In this paper, we review the status of the multifunctional experimental platform at the National Laboratory of High Power Laser and Physics(NLHPLP). The platform, including the SG-II laser facility, SG-II 9th beam, SG-II upgrade(SG-II UP) facility, and SG-II 5 PW facility, is operational and available for interested scientists studying inertial confinement fusion(ICF) and a broad range of high-energy-density physics. These facilities can provide important experimental capabilities by combining different pulse widths of nanosecond, picosecond, and femtosecond scales. In addition, the SG-II UP facility, consisting of a single petawatt system and an eight-beam nanosecond system, is introduced including several laser technologies that have been developed to ensure the performance of the facility. Recent developments of the SG-II 5 PW facility are also presented. | Jianqiang Zhu Jian Zhu Xuechun Li Baoqiang Zhu Weixin Ma Xingqiang Lu Wei Fan Zhigang Liu Shenlei Zhou Guang Xu Guowen Zhang Xinglong Xie Lin Yang Jiangfeng Wang Xiaoping Ouyang Li Wang Dawei Li Pengqian Yang Quantang Fan Mingying Sun Chong Liu Dean Liu Yanli Zhang Hua Tao Meizhi Sun Ping Zhu Bingyan Wang Zhaoyang Jiao Lei Ren Daizhong Liu Xiang Jiao Hongbiao Huang Zunqi Lin | 2018 | High Power Laser Science and Engineering2018，6，4： | 8 |

| 4 | Intersected functional zone of transcriptional regulators patterns stemness within stem cell niche of root apical meristem显示文摘Root stem cell niche(SCN)consists of a quiescent center(QC)and surrounding stem cells.Disrupted symplastic communication leads to loss of stemness in the whole SCN.Several SCN regulators were reported to move between cells for SCN main-tenance.However,single mutant of these regulators is insu?cient to abolish QC stemness despite the high differentiation rate in surrounding stem cells.To dis-sect the mechanism behind such distinct stemness in SCN,we combined the mis-expression strategy with pWOX5:icals3m system in which QC is symplastically isolated.We found the starch accumulation in QC could be synergistically repressed by WUSCHEL-RE-LATED HOMEOBOX 5(WOX5),SHORT-ROOT(SHR),SCARCROW(SCR),and PLETHORA(PLT).Like PLTs,other core regulators also exhibited dimorphicfunctions by inhibiting differentiation at a higher dose while promoting cell division at a low protein level.Being located in the center of the intersected ex-pression zones,QC cells receive the highest level of core regulators,forming the most robust stemness within SCN.WUSCHEL-RELATED HOMEOBOX 5 was su?cient to activate PLT1/2 expression,contributing to the QC-enriched PLTs.Our results provide ex-perimental evidence supporting the long-standing hypothesis that the combination of spatial ex-pression,synergistic function and dosage effect of core regulators result in spatially distinct stemness in SCN. | Meizhi Xu Xu Gu Nengsong Liang Xinxin Bian Hong Wang Yaxin Qin Limin Pi Shuang Wu | 2020 | Journal of Integrative Plant Biology2020，62，7： | 1 |

| 6 | Loss or duplication of key regulatory genes coincides with environmental adaptation of the stomatal complex in Nymphaea colorata and Kalanchoe laxiflora显示文摘The stomatal complex is critical for gas and water exchange between plants and the atmosphere.Originating over 400 million years ago,the structure of the stomata has evolved to facilitate the adaptation of plants to various environments.Although the molecular mechanism of stomatal development in Arabidopsis has been widely studied,the evolution of stomatal structure and its molecular regulators in different species remains to be answered.In this study,we examined stomatal development and the orthologues of Arabidopsis stomatal genes in a basal angiosperm plant,Nymphaea colorata,and a member of the eudicot CAM family,Kalanchoe laxiflora,which represent the adaptation to aquatic and drought environments,respectively.Our results showed that despite the conservation of core stomatal regulators,a number of critical genes were lost in the N.colorata genome,including EPF2,MPK6,and AP2C3 and the polarity regulators BASL and POLAR.Interestingly,this is coincident with the loss of asymmetric divisions during the stomatal development of N.colorata.In addition,we found that the guard cell in K.laxiflora is surrounded by three or four small subsidiary cells in adaxial leaf surfaces.This type of stomatal complex is formed via repeated asymmetric cell divisions and cell state transitions.This may result from the doubled or quadrupled key genes controlling stomatal development in K.laxiflora.Our results show that loss or duplication of key regulatory genes is associated with environmental adaptation of the stomatal complex. | Meizhi Xu Fei Chen Shilian Qi Liangsheng Zhang Shuang Wu | 2018 | Horticulture Research2018，5，1： | 0 |
| 7 | Symplastic communication in the root cap directs auxin distribution to modulate root development显示文摘Root cap not only protects root meristem,but also detects and transduces the signals of environmental changes to affect root development.The symplastic communication is an important way for plants to transduce signals to coordinate the development and physiology in response to the changing enviroments.However,it is unclear how the symplastic communication between root cap cells affects root growth.Here we exploit an inducible system to specifically block the symplastic communication in the root cap.Transient blockage of plasmodesmata(PD)in differentiated collumella cells severely impairs the root development in Arabidopsis,in particular in the stem cell niche and the proximal meristem.The neighboring stem cell niche is the region that is most sensitive to the disrupted symplastic communication and responds rapidly via the alteration of auxin distribution.In the later stage,the cell division in proximal meristem is inhibited,presumably due to the reduced auxin level in the root cap.Our results reveal the essential role of the differentiated collumella cells in the root cap mediated signaling system that directs root development. | Meng Li Mengxue Wang Qingyun Lin Mengyao Wang Xufang Niu Jie Cheng Meizhi Xu Yaxin Qin Xinyi Liao Jian Xu Shuang Wu | 2022 | Journal of Integrative Plant Biology2022，64，4： | 0 |
