| 1 | DEAP1 encodes a fasciclin-like arabinogalactan protein required for male fertility in rice显示文摘Arabinogalactan proteins(AGPs)are widely distributed in plant cells.Fasciclin-like AGPs(FLAs)belong to a subclass of AGPs that play important roles in plant growth and development.However,little is known about the biological functions of rice FLA.Herein,we report the identification of a male-sterile mutant of DEFECTIVE EXINE AND APERTURE PATTERNING1(DEAP1)in rice.The deap1 mutant anthers produced aberrant pollen grains with defective exine formation and a flattened aperture annulus and exhibited slightly delayed tapetum degradation.DEAP1 encodes a plasma membrane-associated member of groupⅢplant FLAs and is specifically and temporally expressed in reproductive cells and the tapetum layer during male development.Gene expression studies revealed reduced transcript accumulation of genes related to exine formation,aperture patterning,and tapetum development in deap1 mutants.Moreover,DEAP1 may interact with two rice D6 PROTEIN KINASE-LIKE3 s(OsD6PKL3s),homologs of a known Arabidopsis aperture protein,to affect rice pollen aperture development.Our findings suggested that DEAP1 is involved in male reproductive development and may affect exine formation and aperture patterning,thereby providing new insights into the molecular functions of plant FLAs in male fertility. | Dan Zhou Ting Zou Kaixuan Zhang Pingping Xiong Fuxing Zhou Hao Chen Gongwen Li Kaiyou Zheng Yuhao Han Kun Peng Xu Zhang Shangyu Yang Qiming Deng Shiquan Wang Jun Zhu Yueyang Liang Changhui Sun Xiumei Yu Huainian Liu Lingxia Wang Ping Li Shuangcheng Li | 2022 | Journal of Integrative Plant Biology2022，64，7： | 2 |

| 5 | The genesis and resource potential of gold deposits in the Liaodong Peninsula显示文摘Plenty of gold deposits related to Late Mesozoic craton destruction are widely distributed in eastern North China Craton. However, significant differences in research degrees, ore-forming characteristics, and proven reserves exist among different regions in the North China Craton. The Liaodong Peninsula has similar regional geological characteristics to those of the Jiaodong Peninsula, with both experiencing craton destruction during Late Mesozoic, but the two areas have substantial differences in terms of gold mineralization and the proven gold resources. Based on regional geology, Mesozoic magmatictectonic evolution and ore geology, combined with integrated geophysical exploration and big data AI resource prediction, in this paper, we propose that the ore-forming materials of Late Mesozoic gold deposits in Liaodong were mainly originated from mantle-derived melts and/or fluids induced by craton destruction. The gold deposits were primarily controlled by NE-NNEtrending faults, mainly classified as fracture-controlled altered rock-type and sulfide-bearing quartz vein-type. Moreover, our study predicts that the Yalu River fault zone and its related secondary faults, as well as the periphery and deeper parts of known goldfields, are the important regions for future gold resource exploration. The Yalu River metallogenic belt has an enormous potential for gold resources, and the Liaodong Peninsula has a potential to add thousands of tons of gold resources. | Rixiang ZHU Jin-Hui YANG Gongwen WANG Qingdong ZENG Guoqiang XUE Tao XU Xinghui LI Peng ZHANG Da LEI Guang ZHU | 2024 | Science China Earth Sciences2024，67，3： | 0 |
| 6 | Fractal Nature of a Fracture Surface in Layered Solids显示文摘We study the crack propagation in layered solids and find that when there exists an easy-fractured layer,the fractal surface becomes more rough,which is characterized by larger fractal dimension. | CAO Qunshen PENG Gongwen TIAN Decheng | 1991 | Chinese Physics Letters1991，8，5： | 0 |
| 7 | Diffusion-Limited Aggregation of Dimers显示文摘We have simulated the diffusion-lirpited growth of dimers on a two-dimensional triangluar lattice and have found that if tips of the dimers have different polarities,the resulting clusters,due to the alignment of the dimers and polarities chosen,are less dense than the clusters generated without polarities.These results make our model an effective way to demonstrate the role of the sticking probabilities in the diffusion-limited aggregation. | CAO Qunsheng PENG Gongwen TIAN Decheng | 1992 | Chinese Physics Letters1992，9，3： | 0 |
| 8 | Field-Biased Diffusion-Limited Aggregation in Electrochemical Deposition System显示文摘We extend the diffusion-limited aggregation model of Witten and Sander to the electrochemical deposition system by considering the effects of the external electric field.A jump probability for field-biased-difTusion is reasonably deduced,which enables us to obtain a series of loopless random fractals with varying fractal dimensions. | PENG Gongwen TIAN Decheng | 1992 | Chinese Physics Letters1992，9，7： | 0 |
