| 1 | An Ethylene-inhibited NF-YC Transcription Factor RhNF-YC9 Regulates Petal Expansion in Rose显示文摘The speed of flower opening is closely related to their ornamental period.Ethylene functions as a negative regulator involved in the regulation of the petal expansion process.In this study,we isolated a NF-YC transcription factor gene,RhNF-YC9,fromrose petals.RhNF-YC9 expression was induced at the early stages of flower opening but was inhibited by ethylene treatment.Silencing RhNF-YC9 decreased the speed of petal expansion from stage 2 to stage 5.The expressions of 11 cell expansion-related genes involved in cell wall loosening,cell turgor modulation,and cytoskeleton remodeling were significantly down-regulated in RhNF-YC9-silenced petals.We also found that silencing RhNF-YC9 decreased the expression of gibberellin acid(GA)biosynthetic gene RhGA20ox while significantly increasing the transcripts of GA catabolic gene RhGA2ox,reducing the accumulation of GA4 and GA7.The influence of ethylene treatment on the expression of RhGA20ox and RhGA2ox showed the same trend.These results together suggested that RhNF-YC9 positively regulated the speed of petal expansion and mediated the crosstalk between ethylene and GA.Our findings revealed a new insight into the function of NF-YC transcription factors involved in ethylene-regulated petal expansion. | Changxi Chen Nisar Hussain Yaru Wang Mingtong Li Lin Liu Meizhu Qin Nan Ma Junping Gao Xiaoming Sun | 2020 | Horticultural Plant Journal2020，6，6： | 9 |
| 2 | Light-powered direction-controlled micropump显示文摘micropump 导致它的包围液体的流动并且在象化学察觉到或集体交通那样的许多应用是极其有希望的。然而,它仍然正在质问操作它的抽的方向。在这研究,我们基于 perovskite 并且 poly 检验二进制 micropump [(2-methoxy-5-ethylhexyloxy )-1,4-phenylenevinylene](MEHPPV ) 。micropump 在光的影响下面是运作的。光在控制 micropump 的抽的现象展出重要通用性。它管理开始和站并且也调整速度和方向。方向控制与崭新的抽的行为和函数为 micropumps 的开发意味着巨大的机会(例如像心跳的抽,校正,和扩大) 。这在各种各样的领域里使他们潜在地有用。因此, micropump 在学习能为多样的应用程序向更复杂的 micropumps 的进一步的开发作为关键步扮演的水流报导了,这被期望。 | Mingtong Li Yajun Su Hui Zhang Bin Dong | 2018 | Nano Research2018，11，4： | 0 |
| 3 | Development of an Omni-Directional Shear Horizontal Wave Transducer Based on a Radially Poled Piezoelec trie Ring显示文摘For the inspection of large plate-like structures,the omni-directional guided wave transducer-based system has been regarded as an effective tool since only a few transducers are required to cover the entire inspection area without blind zones.In comparison with Lamb waves,the shear horizontal(SH)wave is more promising because its fundamental mode is non-dispersive.In this work,we proposed an omni-directional SH wave piezoelec trie t ransducer(OSH-PT)based on a radially poled d24-mode PZT ring.Eoth the finite element simulations and experiments were carried out to demonstrate its performance in generating and receiving SH°wave.Results showed that the radially poled OSH-PT could generate single-mode SHo wave and receive SHo wave only over a wide frequency range from 70 to 200 kHz.The obtained signal-to-noise ratio can reach up to 26 dB in generation and 24 dB in reception.The omni-directivity of this OSH-PT is also very good with the deviation only about 6%in both generation and reception of SHo wave.Considering its easy fabrication,low cost and superior performances,this proposed OSH-PT may promote the applications of SHo wave-based inspection in structural health monitoring and nondestructive testing. | Qiang Huan Mingtong Chen Ai-Kah Soh Faxin Li | 2019 | Acta Mechanica Solida Sinica2019，32，1： | 0 |
| 4 | A unidirectional SH wave transducer based on phase-controlled antiparallel thickness-shear(d15)piezoelectric strips显示文摘In recent years,shear horizontal(SH)waves are being paid more and more attention to in structural health monitoring as it has only one displacement component.In this paper,a unidirectional SH wave transducer based on phase-controlled antiparallel thickness-shear(d15)piezoelectric strips(APS)is proposed.Here two pairs of identical APS were used each of which is a bidirectional SH wave transducer.By setting the interval between the two pairs of APS as 1/4 wavelength and the excitation delay between them as 1/4 period of the central operating frequency,unidirectional SH waves can be excited.Both finite element simulations and experiments were performed to validate the proposed design.Results show that SH0 waves were successfully excited only along one direction and those along the unwanted directions were suppressed very well.The proposed unidirectional SH wave transducer is very helpful to study the fundamentals and applications of SH waves. | Mingtong Chen Qiang Huan Faxin Li | 2020 | Theoretical & Applied Mechanics Letters2020，10，5： | 0 |
