Luam yeeb mosaic virus feem ntau yog kis los ntawm tsob ntoo mus rau tsob ntoo ntawm qhov txhab ua los ntawm txhais tes tsis huv, khaub ncaws lossis khoom siv xws li txiav txiab thiab hoes. Qhov no yog vim TMV tshwm sim nyob rau hauv siab heev concentration nyob rau hauv feem ntau cov nroj tsuag cell. Cov nroj tsuag yuam kev qhov no rau nws tus kheej RNA, thiab pib tsim cov kab mob kis.
Tsuas yog li ntawd, cov tsos mob ntawm TMV yog dab tsi?
Cov tsos mob cuam tshuam nrog TMV kab mob:
- stunting.
- mosaic qauv ntawm lub teeb thiab tsaus ntsuab (los yog daj thiab ntsuab) ntawm nplooj.
- malformation ntawm nplooj los yog cov ntsiab lus loj hlob.
- daj streaking ntawm nplooj (tshwj xeeb tshaj yog monocots)
- daj spotting ntawm nplooj.
- txawv daj tsuas yog cov leeg.
Ib yam nkaus, tib neeg puas tuaj yeem kis tus kab mob mosaic luam yeeb? Tib neeg muaj cov tshuaj tiv thaiv kab mob rau tsob ntoo kab mob vais lav : pov thawj los ntawm luam yeeb mosaic virus . Luam yeeb mosaic virus ( TMV ), ib tug dav nroj tsuag kab mob, muaj nyob rau hauv luam yeeb (suav nrog luam yeeb thiab tsis haus luam yeeb luam yeeb ) raws li zoo raws li nyob rau hauv ntau lwm yam nroj tsuag. Tsob ntoo cov kab mob ua tsis rov ua dua lossis ua rau muaj kab mob hauv tib neeg lossis lwm yam tsiaj.
Ib yam li ntawd, nws raug nug, TMV kho li cas?
Kev kho mob thiab kev tswj Ib qho ntawm cov txheej txheem tswj hwm rau TMV yog kev huv huv, suav nrog tshem tawm cov nroj tsuag uas muaj kab mob thiab ntxuav tes ntawm txhua qhov cog. Nws tau hypothesized tias tus TMV genome yuav rov coated sai sai thaum nkag mus rau hauv lub xov tooj ntawm tes, yog li nws tiv thaiv qhov pib ntawm TMV rov ua dua.
Peb tuaj yeem tiv thaiv tus kab mob luam yeeb mosaic li cas?
Tiv thaiv Mosaic Virus
- Cog cov nroj tsuag tiv taus thaum muaj nyob hauv koj lub vaj.
- Cov kab mob mosaic feem ntau kis tau los ntawm kab, tshwj xeeb tshaj yog aphids thiab leafhoppers.
- Tswj koj cov nyom.
- Txhawm rau zam kev haus luam yeeb mosaic tus kab mob, tseb noob hauv 10 feem pua tshuaj dawb ua ntej cog thiab zam kev tuav cov luam yeeb nyob ze cov nroj tsuag.

Dab tsi yog qhov sib txawv ntawm echocardiogram ua npuas thiab yog vim li cas nws thiaj siv?
Cov npuas dej sib txawv echocardiogram tuaj yeem pab kuaj xyuas daim ntawv pov thawj foramen ovale (PFO) lossis qhov atrial septal defect (ASD). Thaum lub sijhawm kuaj, cov dej ntsev (ntsev) ua npuas tau txhaj rau hauv cov ntshav thiab cov kws tshaj lij cardio saib ntawm lub vijtsam thaum lawv ntws mus rau hauv plawv
Puas yog TMV yog tus kab mob kis?
1) Helical Capsids: Thawj qhov piv txwv uas kawm tau zoo tshaj plaws yog cov nroj tsuag haus luam yeeb mosaic virus (TMV), uas muaj SS RNA genome thiab lub tsho tiv no protein ua los ntawm ib leeg, 17.5 kd protein. Tag nrho cov no yog cov kab mob hauv lub hnab (saib hauv qab)
Peb yog vim li cas vim li cas lub cell faib?
Nov yog cov laj thawj vim li cas cov cell faib. Vim li cas 1: Mitosis thiab meiosis yog cov txheej txheem tseem ceeb. Vim li cas 2: Cell faib rau lub cev kev loj hlob thiab kev loj hlob. Yog vim li cas 3: Cov cell faib los kho peb lub cev. Kev faib tawm ntawm tes yog qhov tseem ceeb rau peb lub cev kev loj hlob thiab kev loj hlob
Hemoglobin yog dab tsi thiab yog vim li cas nws yog ib qho tseem ceeb protein?
Hemoglobin yog cov protein nyob hauv koj cov qe ntshav liab uas nqa oxygen mus rau koj lub cev thiab cov ntaub so ntswg thiab thauj carbon dioxide los ntawm koj lub cev thiab cov ntaub so ntswg rov qab mus rau koj lub ntsws. Yog tias qhov kev kuaj hemoglobin qhia tias koj qib hemoglobin qis dua li qub, nws txhais tau tias koj muaj cov qe ntshav liab tsawg (anemia)
Dab tsi yog kev txhawb siab vim li cas thiab nws ua haujlwm li cas?
Motivated kev xav. Motivated vim li cas yog qhov tshwm sim kawm nyob rau hauv kev txawj ntse science thiab kev puas siab puas ntsws kev xav uas siv kev xav-kev xav tsis zoo rau kev tsim kom muaj kev ncaj ncees los yog txiav txim siab uas xav tau tshaj plaws es tsis yog cov uas muaj feem cuam tshuam cov pov thawj, thaum tseem txo qis kev paub tsis meej
