主要通过ChIP-seq筛选到SARD1 and CBP60g的靶基因,通过ChIP-qPCR以及定量进行验证,发现其可以调控与SAR(systemic acquired resistance),ETI 及PTI正向调控相关基因;还发现SARD1 and CBP60g可结合一些免疫负调控基因,推测是与SA反馈抑制相关,避免自身免疫。另外还通过分析发现二者的结合元件GAAATTT,利用luciferase reporter...
Two pathogen-induced transcription factors, SAR DEFICIENT1 (SARD1) and CAM-BINDING PROTEIN 60-LIKE G (CBP60g), regulate the expression of ICS1 and are required for pathogen induction of SA synthesis23,24,25. Following pathogen infection, SARD1 and CBP60g are recruited to the promoter of ICS...
Loss of both CBP60g and SARD1 severely impacts the plants ability to produce SA in response to bacterial inoculation and renders the plant susceptible to infection. In an electrophoretic mobility shift assay CBP60g and SARD1 were shown to bind specifically to a 10mer oligonucleotide with the ...
SARD1是植物免疫的激活子,会促进植物激素水杨酸SA的产量,激活防御基因的表达。SARD1基因本身是受到侵染的强烈诱导。本文研究了SARD1基因的转录调控。作者利用了酵母单杂试验来鉴定WRKY70。电泳迁移率变动分析法鉴定WRKY70的结合位点,并利用拟南芥的原生质体系统来研究其重要性。通过对wrky70突变体上病原菌的生长、SA浓度...

Salicylic acid(SA) is an essential defence hormone in plants. Upon pathogen infection, induced biosynthesis of SA is mediated by Isochorismate synthase 1(ICS1), whose gene transcription is controlled mainly through two redundant transcription factors, SAR Deficient 1(SARD_1) and Calmodulinbinding ...
Salicylic acid (SA) is a plant defense hormone required for immunity. Arabidopsis NPR1 and NPR3/NPR4 were previously shown to bind SA and all three proteins were proposed as SA receptors. NPR1 functions as a transcriptional co-activator, whereas NPR3/NPR4 were suggested to function as E3 ...
SAR requires an information relay from primary infection to distal tissue and the initiation and maintenance of a self-maintaining phytohormone salicylic acid (SA)-defense loop. In spatial and temporal resolution, we show that calcium-dependent protein kinase CPK5 contributes to immunity and SAR. In...
