anjir mozek amaravirus

anjir mozek amaravirus (fmv) ack khandit, nakaratmak bhavna, ekal-fanse hue rna virus haye joe anjir key paudhon mein anjir mozek roga (fmd), "ficus carica" kaa kaaran agent honey key liye nirdhaarit kiya jaataa haye. yeh "amaravirus" aur "bunyavirels" crum kaa ack sadasya haye aur mukhya roop seey ariophide mite "asseria ficus" dwara preshit hotaa haye. fmv gambhirta mein alag-alag lakshnon kii ack shrinkhala kaa kaaran bunn sakata haye, jisamen patti chlorosis, vikriti, aur mozek yaa rung badalane key pattern key saath-saath samay seey pahale phal girna shamil haye.
itihas.
anjir mozek roga (aff. aim. dee.) kaa pahali baar 1933 mein iraa jey. dwara viral mool kaa varnan kiya gayaa thaa aur sandeh kiya gayaa thaa. condit aur doubleu.tii.seeng. yeh 2009 mein jeevaan jyot valia, nida aim dwara ack virus key kaaran honey kaa nirdhaaran kiya gayaa thaa. salem, aur brice doubleu. fock. taba seey yeh roga aur usase judey virus grees, itali, spen, turkey, seeriya, tunisia, algeria, jorden, newzealand, chean, grate britten, puerto rico, australia aur sanyukt raajya america mein dekhe gaye hain.
vargeekaran.
fmv koo "amaravirus" vansh mein rakhaa gayaa haye, jisamen anya ekal-fanse, nakaratmak-bodh, khandit rna paudhe key virus shamil hain. imaravirus mein chaar seey chhah genome khand hotey hain. way sancharan key apane tareeke mein bhee aam hain, joe agyaat tantra key saath-saath sancharan key yaantrik tarikon dwara ariophide mite kii vibhinn prajaatiyon key madhyam seey hotaa haye. fmv key alawa, genus "amaravirus" mein "europeeya mountain aish ringspot-associated amaravirus" (emarao), "rose rosset amaravirus" (rrv), "raspberry leaf blotch amaravirus" (rlbv) aur anya prajaatiyan shamil hain.
genome sanrachana.
fmv genome mein khandit (bahu-partite) nakaratmak-bodh, ekal-fanse hue rna hotey hain. lambe samay seey genome key chaar khand honey key baare mein socha jaataa rhaa haye, lekin haal key nishkarshon ney chhah aar. aine. aeye. genome khandon key astitva kaa samarthan kiya haye. pratyek khand mein ack khula padhane kaa dhancha (oh. aar. aff.) hotaa haye.
pahala khand, fmv vcrna 1 (7093 nt), genus "amaravirus" key sabhi viruses key liye aam haye aur virus key 264 kda rna-nirbhar rna polymerase (rdrp) key liye code haye, jisamen aine-terminus key paas endonucles gatividhi haye. doosara khand, vcrna2, (2252 nt) ack 73 kda puttive glycoprotein koo kootbaddh kartaa haye. fmv vcrna3 (1490 nt) ack 35 kda nucleocapsid (aine) protein koo kootbaddh kartaa haye. fmv vcrna4 (1472 nt) ack 40.5 kda protein koo kootbaddh kartaa haye jiska kaary abhee bhee agyaat haye.
dou sabse haal hii mein khoje gaye khand, aar. aine. aeye. 5 aur aar. aine. aeye. 6, anya chaar khandon key vipareet, vansh key bheetar atyadhik sanrakshit naheen hain. shayed aisaa isaliye haye kyonki way katey hue yaa doshpurna hain, lekin unake encode kiye gaye protein key kaary abhee bhee anishchit hain.
koshikaon key beach aur unamen gati (fmv-pee4)।.
sabhi paadap viruses kii tarah, fmv ack andolan protein (mp) koo koshikaon key beach sthanantarit karane mein saksham banaata haye, aamtaur parr plasmodesmata key aakar bahishkaran seema (cell) koo badhaakar viral maarg kii anumati detaa haye. fmv kaa mp sabse adhik sambhavana pee4 haye, ack anuman joe plasma jhilli mein isake sthaaniyakaran dwara samarthit haye lekin abhee taka nishchit roop seey naheen dikhaaya gayaa haye.
cap snatching key madhyam seey genome pratikriti.
aar. aine. aeye. aashrit aar. aine. aeye. polymerase protein (aar. dee. aar. pee.) key liye aff. aim. vee. vee. vee. see. aar. aine. aeye. 1 code, jisamen apane aine. terminus parr endonucles kaary hotaa haye aur jise virian mein paik kiya jaataa haye. ack baar jaba virian ack koshika mein pravesh curr jaataa haye, tou aar. dee. aar. pee. mezban aim. aar. aine. aeye. seey juda jaataa haye aur aim. aar. aine. aeye. sanshleshan key liye primer key roop mein upayog karane key liye aur mezban anuvaad tantra koo highzac karane key tareeke key roop mein 5 'methylated cap koo alag karane key liye endonucles gatividhi kaa upayog kartaa haye.
dee. aim. bee. aiss. aur ell. aff. pee. aiss..
aff. aim. vee. key saath sankraman key parinamswarup alag-alag dohare jhilli nikaay yaa kann hotey hain, jinhen dee. aim. bee. aiss. yaa dee. aim. pee. aiss. kahaa jaataa haye, sankramit perenkima koshikaon key cytosol mein vyaas mein 90-200 aine. aim.. yeye dohare jhilli-baddh shareer ack fibrill matricks seey ghire hotey hain aur kewal ack macro star parr mozek key lakshan dikhaane vaale pattiyon mein paae jaate hain, kabhi bhee ack niyantran key roop mein upayog kiye jaane vaale asankramit ootak mein naheen.
kuchh kismon ney ootakon mein lambe, lacheele, chhad key aakar key, virus jaise kanon (ell. aff. pee. aiss.) koo bhee dikhaaya haye joe necrosis key sanket dikhaate hain. yeye asankramit niyantran ootakon mein bhee naheen dekhe jaate hain. naa hii kissy prakaar kaa koee nirdhaarit kaary hotaa haye.
lakshan.
fmv key parinamswarup vibhinn prakaar key lakshan hotey hain, jinamen seey kuchh mein majboot krishi nuksan hoe sakata haye, jaise kii phal kii paidawar mein kamee. lakshnon mein patti key mozek pattern kii upasthiti, vikshepan, phal kii paidawar mein kamee, nason mein patti, ringspot, pattiyon kii vikriti aur chlorosis, aur falon parr peela dhabba shamil hain.
agyaat aur bhavishya kaa shodh.
iss virus kii aanvik sanrachana aur kaary key kaee pahalu abhee bhee agyaat hain. viral genome, aar. aine. aeye. 4 parr chauthe khand dwara encode kiye gaye protein kaa abhee bhee ack agyaat kaary haye. isake alawa, aff. aim. vee. kii pratikriti key sateek aanvik tantra, aur samanya roop seey "amaravirus" pratikriti kii abhee bhee pushti naheen hui haye. vartamaan shodh dee. aim. bee. aiss./dee. aim. pee. aiss. kii prakriti key baare mein adhik jaanane parr bhee kaam curr rhaa haye, kyonki unhein sankramit paudhon seey alag karna mushkil haye.
