| 9 | The C-terminal 17 amino acids of the photoreceptor UVR8 is involved in the fine-tuning of UV-B signaling^FA显示文摘Plant UV-B responses are mediated by the photoreceptor UV RESISTANCE LOCUS 8 (UVR8). In re-sponse to UV-B irradiation, UVR8 homodimers dissociate into monomers that bind to the E3 ubiquitin ligase CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1). The in-teraction of the C27 domain in the C-terminal tail of UVR8 with the WD40 domain of COP1 is critical for UV-B sig-naling. However, the function of the last 17 amino acids (C17) of the C-terminus of UVR8, which are adjacent to C27, is unknown, although they are largely conserved in land plants. In this study, we established that Arabidopsis thaliana UVR8 C17 binds to full-length UVR8, but not to COP1, and reduces COP1 binding to the remaining portion of UVR8, including C27. We hypothesized that overexpression of C17 in a wild-type background would have a dominant negative effect on UVR8 activity;however, C17 overexpression caused strong silencing of endogenous UVR8, precluding a detailed analysis. We therefore generated YFP-UVR8N423 transgenic lines, in which C17 was deleted, to examine C17 function in-directly. YFP-UVR8N423 was more active than YFP-UVR8, suggesting that C17 inhibits UV-B signaling by attenuating binding between C27 and COP1. Our study reveals an inhibitory role for UVR8 C17 in fine-tuning UVR8–COP1 interactions during UV-B signaling. | Li Lin Huaxi Dong Guoqian Yang Ruohe Yin | 2020 | Journal of Integrative Plant Biology2020，62，9： | 3 |
| 10 | Control of Plant Growth and Defense by Photoreceptors:From Mechanisms to Opportunities in Agriculture显示文摘Plants detect and respond to the proximity of competitors using light signals perceived by photoreceptor proteins.A low ratio of red to far-red radiation(R:FR ratio)is a key signal of competition that is sensed by the photoreceptor phytochrome B(phyB).Low R:FR ratios increase the synthesis of growth-related hormones,including auxin and gibberellins,promoting stem elongation and other shade-avoidance responses.Other photoreceptors that help plants to optimize their developmental configuration and resource allocation patterns in the canopy include blue light photoreceptors,such as cryptochromes and phototropins,and UV receptors,such as UVR8.All photoreceptors act by directly or indirectly controlling the activity of two major regulatory nodes for growth and development:the COP1/SPA ubiquitin E3 ligase complex and the PIF transcription factors.phyB is also an important modulator of hormonal pathways that regulate plant defense against herbivores and pathogens,including the jasmonic acid signaling pathway,In this Perspective,we discuss recent advances on the studies of the mechanisms that link photoreceptors with growth and defense.Understanding these mechanisms is important to provide a functional platform for breeding programs aimed at improving plant productivity,stress tolerance,and crop health in species of agronomic interest,and to manipulate the light environments in protected agriculture. | Ronald Pierik Carlos L.Ballare | 2021 | Molecular Plant2021，14，1： | 2 |
| 11 | UV-B light and its application potential to reduce disease and pest incidence in crops显示文摘Ultraviolet-B radiation(280–315 nm),perceived by the plant photoreceptor UVR8,is a key environmental signal that influences plant growth and development and can reduce disease and pest incidence.The positive effect of UV-B on disease resistance and incidence in various plant species supports the implementation of supplemental UV-B radiation in sustainable crop production.However,despite many studies focusing on UV-B light,there is no consensus on the best mode of application.This review aims to analyze,evaluate,and organize the different application strategies of UV-B radiation in crop production with a focus on disease resistance.We summarize the physiological effects of UV-B light on plants and discuss how plants perceive and transduce UV-B light by the UVR8 photoreceptor as well as how this perception alters plant specialized metabolite production.Next,we bring together conclusions of various studies with respect to different UV-B application methods to improve plant resistance.In general,supplemental UV-B light has a positive effect on disease resistance in many plant–pathogen combinations,mainly through the induction of the production of specialized metabolites.However,many variables(UV-B light source,plant species,dose and intensity,timing during the day,duration,background light,etc.)make it difficult to compare and draw general conclusions.We compiled the information of recent studies on UV-B light applications,including e.g.,details on the UV-B light source,experimental set-up,calculated UV-B light dose,intensity,and duration.This review provides practical insights and facilitates future research on UV-B radiation as a promising tool to reduce disease and pest incidence. | Prisca Meyer Bram Van de Poel Barbara De Coninck | 2021 | Horticulture Research2021，8，1： | 2 |

| 13 | Multiple quantitative trait loci contribute to resistance to bacterial canker incited by Pseudomonas syringae pv.actinidiae in kiwifruit(Actinidia chinensis)显示文摘Pseudomonas syringae pv.actinidiae(Psa)biovar 3,a virulent,canker-inducing pathogen is an economic threat to the kiwifruit(Actinidia spp.)industry worldwide.The commercially grown diploid(2×)A.chinensis var.chinensis is more susceptible to Psa than tetraploid and hexaploid kiwifruit.However information on the genetic loci modulating Psa resistance in kiwifruit is not available.Here we report mapping of quantitative trait loci(QTLs)regulating resistance to Psa in a diploid kiwifruit population,derived from a cross between an elite Psa-susceptible‘Hort16A’and a resistant male breeding parent P1.Using high-density genetic maps and intensive phenotyping,we identified a single QTL for Psa resistance on Linkage Group(LG)27 of‘Hort16A’revealing 16–19%phenotypic variance and candidate alleles for susceptibility and resistance at this loci.In addition,six minor QTLs were identified in P1 on distinct LGs,exerting 4–9%variance.Resistance in the F1 population is improved by additive effects from‘Hort16A’and P1 QTLs providing evidence that divergent genetic pathways interact to combat the virulent Psa strain.Two different bioassays further identified new QTLs for tissue-specific responses to Psa.The genetic marker at LG27 QTL was further verified for association with Psa resistance in diploid Actinidia chinensis populations.Transcriptome analysis of Psa-resistant and susceptible genotypes in field revealed hallmarks of basal defense and provided candidate RNA-biomarkers for screening for Psa resistance in greenhouse conditions. | Jibran Tahir Stephen Hoyte Heather Bassett Cyril Brendolise Abhishek Chatterjee Kerry Templeton Cecilia Deng Ross Crowhurst Mirco Montefiori Ed Morgan Andrew Wotton Keith Funnell Claudia Wiedow Mareike Knaebel Duncan Hedderley Joel Vanneste John McCallum Kirsten Hoeata Amardeep Nath David Chagné Luis Gea Susan E.Gardiner | 2019 | Horticulture Research2019，6，1： | 0 |
| 14 | Phytochrome B regulates jasmonic acid-mediated defense response against Botrytis cinerea in Arabidopsis显示文摘The phytochrome B mediated light signaling integrates with various phytohormone signalings to control plant immune response.However,it is still unclear whether phyB-mediated light signaling has an effect on the biosynthesis of jasmonate during plant defense response against Botrytis cinerea.In this study,we demonstrated that phyB-mediated light signaling has a role in this process.Initially,we confirmed that phyb plants were obviously less resistant to B.cinerea while phyB overexpressing plants showed significantly enhanced resistance.We also found that the expression of numerous JA biosynthesis genes was promoted upon treatment with red or white light when compared to that of darkness,and that this promotion is dependent on phyB.Consistent with the gene expression results,phyb plants accumulated reduced pool of JA-lle,indicating that phyB-mediated light signaling indeed increased JA biosynthesis.Further genetic analysis showed that light-mediated JAZ9 degradation and phyB-enhanced resistance were dependent on the receptor COI1,and that pifl/3/4/5(pi/q)can largely rescue the severe symptom of phyb.Taken together,our study demonstrates that phyB may participate in plant defense against B.cinerea through the modulation of the biosynthesis of JA. | Shengyuan Xiang Songguo Wu Yifen Jing Ligang Chen Diqiu Yu | 2022 | Plant Diversity2022，44，1： | 0 |
| 15 | 番茄UVR8基因对果实采后贮藏品质的影响显示文摘紫外线抗性位点8(UV resistance locus 8,UVR8)编码光受体蛋白,负责UV-B感知和信号转导,被认为参与调控其他的生理反应。文章对UVR8过表达和基因沉默植株的果实进行分析,结果表明:与对照组相比,UVR8过表达转基因番茄果实有着更长的贮藏期,其果实硬度显著高于野生型;对UVR8转基因番茄果实的过氧化氢酶(CAT)和过氧化物酶(POD)活性进行测定,结果发现过表达番茄果实的CAT、POD的酶活与野生型相比均显著提高,分别是野生型的2.5、2.3倍,而基因沉默番茄果实的酶活与野生型相比显著下降;同时对脂质过氧化指标的丙二醛(MDA)进行分析,表明每g过表达番茄果实中MDA物质的量有所降低,仅为野生型的1/2,而且每g基因沉默番茄果实中MDA物质的量与野生型相比明显升高。由以上结果可推测,UVR8基因在延长番茄果实采后贮藏期中发挥了作用。 | 林智城 李佳男 汪宏涛 徐娟 唐晓凤 | 2023 | 合肥工业大学学报(自然科学版)2023，46，2： | 0 |
