Theoretical Simulation of Surface Evolution Using the Random Deposition and Surface Relaxation for Metal Oxide Film in Atomic Layer Deposition

Journal of Materials Science & Technology 2010年第4期26卷 371-374页

作者： Ji-hoon ahn Se-Hun Kwon Jin-Hyock Kim Ja-Yong Kim sang-Won Kang Department of Materials Science and Engineering Korea Advanced Institute of Science and Technology373-1Kusong-dongYusong-guTaejon 305-701Korea Hynix Semiconductor Incorporated San 136-1Ami-riBubal-eubIcheon-siKyongki-do467-701Korea

Atomic layer deposition （ALD） has become an essential deposition method for forming nanometer scale thin films in the microelectronics industry, and its applications have been extended to multi-component thin films, as well as to single metal oxide films. In order to investigate the development of the surface structure of ultra-thin film qualitatively as well as quantitatively, ALD processes are simulated with a molecular scale. For this simulation, the film materials are deposited on a imaginary substrate that consists of small lattice. The deposition behaviors are described by using random deposition （RD） model or random deposition with surface relaxation （RDSR） model as the ALD growth mode, and the proposed model was applied to the deposition of SrO-TiO2 thin films. Through this work, growth characteristics such as surface morphology, deposited film coverage can be predicted.

Light Intensity and Floral Transition： Chloroplast Says ＂Time to Flower!＂

引用

Molecular Plant 2016年第12期9卷 1551-1553页

作者： Hendry Susila Suhyun Jin Ji hoon ahn Creative Research Initiatives Department of Life Sciences Korea University Seoul 02841 South Korea

Flowering represents a pivotal developmental transition from the vegetative stage to the reproductive stage. The timing of flower- ing must be carefully controlled under ever-changing environ- mental conditions to ensure successful reproduction. Extensive genetic and molecular biological analyses in the model species Arabidopsis thaliana have identified important regulators of flowering time and revealed a complex network of highly inter- connected pathways that are regulated by seasonal cues （e.g., light and temperature） and internal factors （e.g., age and nutrient availability）（Bouche et al., 2016）.

Arabidopsis ABF3 and ABF4 Transcription Factors Act with the NF-YC Complex to Regulate SOC1 Expression and Mediate Drought-Accelerated Flowering

引用

Molecular Plant 2019年第4期12卷 489-505页

作者： Keumbi Hwang Hendry Susila Zeeshan Nasim Ji-Yul Jung Ji hoon ahn Department of Life Sciences Korea University Anamro 145 Seongbuk-Gu Seoul 02841 South Korea

The drought-escape response accelerates flowering in response to drought stress, allowing plants to adaptively shorten their life cycles. Abscisic acid (ABA) mediates plant responses to drought, but the role of ABA-responsive element (ABRE)-binding factors (ABFs) in the drought-escape response is poorly understood. Here, we show that Arabidopsis thaliana ABF3 and ABF4 regulate flowering in response to drought through transcriptional regulation of the floral integrator SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1). The abf3 abf4 mutant displayed ABA-insensitive late flowering under long-day conditions. Ectopic expression of ABF3 or ABF4 in the vasculature, but not in the shoot apex, induced early flowering, whereas expression of ABF3 fused with the SRDX transcript!onal repressor domain delayed flowering. We identified SOC1 as a direct downstream target of ABF3/4, and found that SOC1 mRNA levels were lower in abf3 abf4 than in wild-type plants. Moreover, induction of SOC1 by ABA was hampered in abf3 abf4 mutants. ABF3 and ABF4 were enriched at the -1028- to -657-bp region of the SOC1 promoter, which does not contain canonical ABF-ABRE-binding motifs but has the NF-Y binding element. We found that ABF3 and ABF4 interact with nuclear factor Y subunit C (NF-YC) 3/4/9 in vitro and in planta, and induction of SOC1 by ABA was hampered in nf-yc3 yc4 yc9 mutants. Interestingly, the abf3 abf4, nf-yc3 yc4 yc9, and sod mutants displayed a reduced drought-escape response. Taken together, these results suggest that ABF3 and ABF4 act with NF-YCs to promote flowering by inducing SOC1 transcription under drought conditions . This mechanism might contribute to adaptation by enabling plants to complete their life cycles under drought stress.

Acupuncture has been broadly used as a major therapeutic tool for at least 2,100 years in East Asia. Acupuncture is used for improving the pathological condition of remote organs, such as stomach, liver, brain, etc. by stimulating skin and muscle with fine metal needles through meridians which have been regarded as pathways of Qi within the body （Ernst, 2006）. Physicians in East Asia have tried to treat many kinds of diseases by acupuncture and it was considerably success- ful. Various diseases for which acupuncture is known to be effective, are neurological diseases, including sequelae of stroke, Alzheimer＇s disease （AD）, Parkinson＇s disease （PD）, and so on （Nam et al., 2013）.

The Arabidopsis Floral Repressor BFT DelaysFlowering by Competing with FT for FD Bindingunder High Salinity

引用

Molecular Plant 2014年第2期7卷 377-387页

Soil salinity is one of the most serious agricultural problems that significantly reduce crop yields in the aridand semi-arid regions. It influences various phases of plant growth and developmental processes, such as seed germina-tion, leaf and stem growth, and reproductive propagation. Salt stress delays the onset of flowering in many plant spe-cies. We have previously reported that the Arabidopsis BROTHER OF FT AND TFL1 （BFT） acts as a floral repressor undersalt stress. However, the molecular mechanisms underlying the BFT function in the salt regulation of flowering inductionis unknown. In this work, we found that BFT delays flowering under high salinity by competing with FLOWERING LOCUST （FT） for binding to the FD transcription factor. The flowering time of FD-deficient fd-2 mutant was insensitive to highsalinity. BFT interacts with FD in the nucleus via the C-terminal domain of FD, which is also required for the interactionof FD with FT, and interferes with the FT-FD interaction. These observations indicate that BFT constitutes a distinct saltstress signaling pathway that modulates the function of the FT-FD module and possibly provides an adaptation strategythat fine-tunes photoperiodic flowering under high salinity.
