| 1 | Tomato SlAN11 regulates flavonoid biosynthesis and seed dormancy by interaction with bHLH proteins but not with MYB proteins显示文摘The flavonoid compounds are important secondary metabolites with versatile human nutritive benefits and fulfill a multitude of functions during plant growth and development.The abundance of different flavonoid compounds are finely tuned with species-specific pattern by a ternary MBW complex,which consists of a MYB,a bHLH,and a WD40 protein,but the essential role of SlAN11,which is a WD40 protein,is not fully understood in tomato until now.In this study,a tomato WD40 protein named as SlAN11 was characterized as an effective transcription regulator to promote plant anthocyanin and seed proanthocyanidin(PA)contents,with late flavonoid biosynthetic genes activated in 35S::SlAN11 transgenic lines,while the dihydroflavonol flow to the accumulation of flavonols or their glycosylated derivatives was reduced by repressing the expression of SlFLS in this SlAN11-overexpressed lines.The above changes were reversed in 35S::SlAN11-RNAi transgenic lines except remained levels of flavonol compounds and SlFLS expression.Interestingly,our data revealed that SlAN11 gene could affect seed dormancy by regulating the expressions of abscisic acid(ABA)signaling-related genes SlABI3 and SlABI5,and the sensitivity to ABA treatment in seed germination is conversely changed by SlAN11-overexpressed or-downregulated lines.Yeast two-hybrid assays demonstrated that SlAN11 interacted with bHLH but not with MYB proteins in the ternary MBW complex,whereas bHLH interacted with MYB in tomato.Our results indicated that low level of anthocyanins in tomato fruits,with low expression of bHLH(SlTT8)and MYB(SlANT1 and SlAN2)genes,remain unchanged upon modification of SlAN11 gene alone in the transgenic lines.These results suggest that the tomato WD40 protein SlAN11,coordinating with bHLH and MYB proteins,plays a crucial role in the fine adjustment of the flavonoid biosynthesis and seed dormancy in tomato. | Yongfeng Gao Jikai Liu Yongfu Chen Hai Tang Yang Wang Yongmei He Yongbin Ou Xiaochun Sun Songhu Wang Yinan Yao | 2018 | Horticulture Research2018，5，1： | 13 |
| 2 | Electrolytic groundwater circulation well for trichloroethylene degradation in a simulated aquifer显示文摘An in situ groundwater remediation process, termed EGCW, was developed in this study by integrating in-well groundwater electrolysis into groundwater circulation well. Groundwater circulation carries electrolytically generated O2 and H2 into the impacted aquifer for in situ biodegradation of contaminants. In a two-dimensional tank filled with field sandy sediments,simulated trichloroethylene(TCE)-contaminated groundwater was circulated between an injection well with electrodes inside and a pumping well. Results from a 50-day EGCW experiment show that in-well electrolysis oxygenated most region near the injection well, and 10 mg/L TCE was mainly biodegraded aerobically to about 2.7 mg/L(73% removal) by the indigenous microbes. Aerobic TCE degradation was enhanced by the pulsed addition of acetate. Together with the proofs of stable carbon isotope fractionation(enrichment factor:-0.57‰–-1.53‰) and microbial community variation after EGCW treatment, aerobic cometabolism was proposed to be the most likely mechanism for TCE degradation. It is interesting to find that the intrinsic organic carbon in aquifer matrix could fuel the aerobic TCE degradation, particularly at low TCE concentrations. EGCW treatment is advantageous in terms of supplying appropriate dosages of electron acceptor(O_(2)) and donor(H_(2)) for in situ bioremediation because groundwater electrolysis and circulation are expedient and controllable. | YUAN SongHu LIU Yang ZHANG Peng TONG Man LIU Hui | 2021 | Science China(Technological Sciences)2021，64，2： | 6 |
| 3 | Telomere-to-telomere and gap-free reference genome assembly of the kiwifruit Actinidia chinensis显示文摘Kiwifruit is an economically and nutritionally important fruit crop with extremely high contents of vitamin C.However,the previously released versions of kiwifruit genomes all have a mass of unanchored or missing regions.Here,we report a highly continuous and completely gap-free reference genome of Actinidia chinensis cv.‘Hongyang’,named Hongyang v4.0,which is the first to achieve two de novo haploid-resolved haplotypes,HY4P and HY4A.HY4P and HY4A have a total length of 606.1 and 599.6 Mb,respectively,with almost the entire telomeres and centromeres assembled in each haplotype.In comparison with Hongyang v3.0,the integrity and contiguity of Hongyang v4.0 is markedly improved by filling all unclosed gaps and correcting some misoriented regions,resulting in∼38.6–39.5 Mb extra sequences,which might affect 4263 and 4244 protein-coding genes in HY4P and HY4A,respectively.Furthermore,our gap-free genome assembly provides the first clue for inspecting the structure and function of centromeres.Globally,centromeric regions are characterized by higher-order repeats that mainly consist of a 153-bp conserved centromere-specific monomer(Ach-CEN153)with different copy numbers among chromosomes.Functional enrichment analysis of the genes located within centromeric regions demonstrates that chromosome centromeres may not only play physical roles for linking a pair of sister chromatids,but also have genetic features for participation in the regulation of cell division.The availability of the telomere-to-telomere and gap-free Hongyang v4.0 reference genome lays a solid foundation not only for illustrating genome structure and functional genomics studies but also for facilitating kiwifruit breeding and improvement. | Junyang Yue Qinyao Chen Yingzhen Wang Lei Zhang Chen Ye Xu Wang Shuo Cao Yunzhi Lin Wei Huang He Xian Hongyan Qin Yanli Wang Sijia Zhang Ying Wu Songhu Wang Yi Yue Yongsheng Liu | 2023 | Horticulture Research2023，10，2： | 4 |
| 4 | A Joint Feedback Bit and Power Allocation Strategy for Multi-cell Systems over Composite Fading Channels显示文摘This paper addresses the joint Feedback bit allocation(FBA) and Power allocation(PA)problem for a limited feedback coordinated multi-cell transmission system over composite fading channels. The Rayleigh/Lognormal fading channel is considered, and the effects of path loss and the macro-level correlation are also taken into account. A modified performance measure, referred to as the virtual sum rate is adopted to facilitate the analysis. The closed forms of the lower bound on virtual sum rate are derived over uncorrelated and correlated shadowed fading channels. Based on the lower bound, we then formulate an optimization problem of maximizing the virtual sum rate under constraints on the total number of feedback bits per MS and the total transmit power per BS. Considering the tight coupling between the FBA and the PA, we solve the optimization problem by solving an alternating sequence of FBA and PA subproblems using a coordinated ascent searching method. Numerical results show that the proposed strategy can converge in a few iterations and generally yield better performance than the conventional FBA schemes under composite fading channels. | MA Yue WANG Xin WANG Haihong GE Songhu WEI Jibo | 2016 | Chinese Journal of Electronics2016，25，3： | 3 |

| 12 | Searching for exoplanets with HEPS:I.detection probability of Earth-like planets in multiple systems显示文摘The astrometry method has great advantages in searching for exoplanets in the habitable zone around solar-like stars. However, the presence of multiple planets may cause a problem with degeneracy when trying to compute accurate planet parameters from observation data and reduce detectability. The degeneracy problem is extremely critical, especially in a space mission which has limited observation time and cadence. In this series of papers, we study the detectability of habitable Earth-mass planets in different types of multi-planet systems, aiming to find the most favorable targets for the potential space mission–Habitable ExoPlanet Survey(HEPS). In the first paper, we present an algorithm to find planets in the habitable zone around solar-like stars using astrometry. We find the detectability can be well described by planets' signal-to-noise ratio(SNR) and a defined parameter S = M2/(T1-T2)2, where M2 and T2are the mass and period of the second planet, respectively. T1 is the period of the planet in the habitable zone. The parameter S represents the influence of planetary architectures. We fit the detectability as a function of both the SNR of the planet in the habitable zone and the parameter S. An Earth-like planet in a habitable zone is harder to detect(with detectability PHP< 80%) in a system with a hot Jupiter or warm Jupiter(within2 AU), in which the parameter S is large. These results can be used in target selections and to determine the priority of target stars for HEPS, especially when we select and rank nearby planet hosts with a single planet. | Zhou-Yi Yu Hui-Gen Liu Ji-Lin Zhou Dong-Hong Wu Ming Yang Songhu Wang Hui Zhang Zi Zhu Jia-Cheng Liu | 2019 | Research in Astronomy and Astrophysics2019，19，1： | 1 |
