Opines yog tsis muaj qhov hnyav molecular sib txuas pom nyob rau hauv cov nroj tsuag cov kab mob hauv cov qog los yog cov hauv paus plaub hauua los ntawm cov kab mob pathogenic ntawm genus Agrobacterium thiab Rhizobium. … Cov opines yog siv los ntawm cov kab mob ua lub zog tseem ceeb, carbon thiab nitrogen qhov chaw.
Kev ua haujlwm ntawm kev xav yog dab tsi?
Opines yog ib chav kawm ntawm carbohydrate derivatives uas ua cov khoom noj rau cov kab mob agrobacteria, thiab uas suav nrog ntau d-fructose-amino acids thiab cov molecules ntsig txog.
Ti plasmid yog dab tsi?
Ti plasmids ntawm Agrobacterium tumefaciens yog cov ntsiab lus sib txuas uas nws hloov mus tau nruj heev. Kev hloov pauv yog tshwm sim los ntawm kev sib txuas lus,ib pab pawg ntawm cov pa roj carbon monoxide sib xyaw ua ke hauv cov kab mob hauv plab. Cov opines kuj induce Ti plasmid-encoded noob yuav tsum tau los ntawm cov kab mob rau opine catabolism.
octopine thiab nopaline yog dab tsi?
Abstract. Crown gall qog ua octopine lossis nopaline lossis tsis muaj qhov sib xyaw, nyob ntawm cov kab mob uas ua rau cov qog. … Cov kab no, uas yog mutant nyob rau hauv cov noob qhia txog octopine los yog nopaline oxidase, tseem khaws cov permease rau cov amino acids thiab virulence.
Lub luag haujlwm tseem ceeb ntawm kev xav txog kev cog noob caj noob ces yog dab tsi?
Opines tsis tsuas yog activates cov noob lub luag haujlwm rau opine metabolism, tab sis kuj qhib QS-nyob ntawm kev ua haujlwm xws liinduction ntawm Ti plasmid conjugation thiab kev txhim kho ntawm Ti plasmid daim ntawv tus lej, txhawb kev kis kab mob siab tshaj plaws. Qhov tseeb, qhov nce ntawm Ti plasmid tus lej luam yuav zoo rau Ti plasmid conjugation.
