Ces dernières années, les facteurs du complexe d'initiation de la traduction eucaryote ont été identifiés comme des déterminants essentiels dans la sensibilité des plantes aux virus à ARN, y compris les potyvirus, genre le plus important à la fois de par leur nombre et leur importance économique chez des espèces légumières, fruitières et de grandes cultures.En particulier, les allèles récessifs mo11 et mo12 du gène mo1 précédemment identifié comme codant pour le facteur d'initiation de la traduction eIF4E, sont actuellement utilisés pour protéger les cultures de laitue contre le potyvirus de la mosaïque de la laitue (LMV).Partant des résultats obtenus au laboratoire démontrant que les déterminants du LMV impliqués dans le contournement de la résistance mo1 comprennent non seulement le domaine codant pour la VPg mais aussi, en amont, l’...
Effective repression of cI transcription from PRM by the bacteriophage λ CI repressor requires binding sites (OL) located 2.4 kb from the promoter. A CI tetramer bound to OL1.OL2 interacts with a tetramer bound near PRM (OR1.OR2), looping the intervening DNA. We previously proposed that in this CI octamer:DNA complex, the distant OL3 operator and the weak OR3 operator overlapping PRM are juxtaposed so that a CI dimer at OL3 can cooperate with a CI dimer binding to OR3. Here we show that OL3 is necessary for effective repression of PRM and that the repressor at OL3 appears to interact specifically with the repressor at OR3. The OL3-CI-OR3 interaction involves the same CI interface used for short-range dimer-dimer interactions and does not occur without the other four operators. The long-range interactions were incorporated into a physic...
How distant enhancer elements regulate the assembly of a transcription complex at a promoter remains poorly understood. Here, we use long-range gene regulation by the bacteriophage λ CI protein as a powerful system to examine this process in vivo. A 2.3-kb DNA loop, formed by CI bridging its binding sites at OR and OL, is known already to enhance repression at the lysogenic promoter PRM, located at OR. Here, we show that CI looping also activates PRM by allowing the C-terminal domain of the α subunit of the RNA polymerase bound at PRM to contact a DNA site adjacent to the distal CI sites at OL. Our results establish OL as a multifaceted enhancer element, able to activate transcription from long distances independently of orientation and position. We develop a physicochemical model of our in vivo data and use it to show that the observe...
Due to the similar life experience with Li Yu, Li Qing Zhao is conducive to inherit the poetry style of Li Yu. Yi An Ci mainly inherited the language pattern, narrative style and the way to show melancholy emotional from Li Yu’s poetry. Li Qing Zhao inherited Li Yu's straightforward style of writing techniques and advocated the use of simple and natural language features. Besides, Li Qing Zhao is good in using syncategorematic term. Li Qing Zhao and Li Yu show their depression by specify the abstract emotion and inverse approach, as well as reflects their sadness by showing the direction of their native countries.
On the other hand, feminine identity causes Li Qing Zhao to be more sensitive and delicate than male poets. Therefore her poetry often show unique female characteristics, such as prefers to use reiteration words, good in...
