Nicotiana (Nicotiana benthamiana)

La Nicotiana benthamiana chirimwa chinomera mushonga, yemhuri yeSolanaceae. Nicotiana uyu anodikanwa nemasayendisiti kutenderera pasirese, anoishandisa mukutsvagisa kwakasiyana-siyana uye zvidzidzo zvehutachiona hwakasiyana uye majekiseni.

Kwakatangira uye pekugara

Icho chirimwa chekuzvarwa cheOceania, kunyanya kuAustralia uko chingaonekwa musango. Kazhinji inokura mumakomo ane matombo, makomo, kana mumapako.

Hunhu Nicotiana benthamiana

La Nicotiana benthamiana Icho chirimwa chine mashizha nemashizha zvine hungwaru pubescent ine glandular trichomes. isu tinodzika mashizha; iwo ekumusoro mapfupi uye akapetwa, nepo ezasi ari echikadzi; basal, ine petiole inenge 6 masentimita kureba.

Maruva ayo machena, ari ega uye asinganhuwi anokura kubva muhapwa, akafanana neakakora bracts mune mamwe matanho ekukura kwayo, chubhu ye corolla yayo, iyo yakareba kusvika makumi maviri kusvika makumi matanhatu emamirimita, inowonekera husiku. Makobvu avo anowanzo kuwedzerwa kana kukombama, zvishoma notched.

Kana zviri zveanthers, maviri acho anowanzo ari pamusoro pemamwe maviri, Ivo vane mashanu stamens, mana acho akachengetedzwa pamusoro pechinyadzo uye chasara pazasi. Mbeu dzayo dzinowanikwa mumacapsule anoenda kubva kune ovoid kuenda kune ellipsoid kusvika pamamirimita gumi nematanhatu pakureba.

Mbeu dzayo dzakasarudzika, ndiko kuti kuita kunge itsvo. Kunyangwe hazvo hunhu hwayo huchiratidza kuda kwekuuchikwa kwemuchinjikwa, chirimwa ichi chinozvimiririra uye chinowanzo tenderera pakuyambutsa.

Curiosities

Kunyange chiri chokwadi, chirimwa chinoshaya immune system inoisiya ichifumurwa nechirwere, inosunungura simba rekumera nekukura nekukurumidza, simba iro rinogona kushandiswa kuzvidzivirira. Ehezve, hunhu uhwu hauratidzike sekubatsira munzvimbo dzine utachiona hwakawanda, asi zviripo, nekuti zvinotendera kuti zvigare pamwe chete nemuvengi wazvo mukuru, kusanaya kwakanyanya mudunhu kwainogara. Kukwanisa kwayo kuburitsa mbeu nekukasira uye kuzvisimbisa, kunyangwe mushure mekudonha kwemvura shoma, kwakubatsira kuti irarame mukati memamiriro ekunze akanyanya eCentral Australia kweanopfuura makore mazana manomwe mazana manomwe.

La Nicotiana benthamiana Yakave ichishandiswa mumarabhoritari kumatunhu ese epasi, mukutsvaga nezvehutachiona uye majekiseni, nekuda kwehunhu hwayo hwekushayikwa kwema immune system. Zvakadaro Izvi zvakasarudzika zvakaita kuti chive chirimwa chinoramba kwazvo.

Kusvika padanho rekuti ndechimwe chezvinhu zvinoshandiswa pakuedza muzvirimwa virology, nekuda kwemhando dzakasiyana dzehutachiona hunogona kuutapurira. Nekudaro, inowanzoitika kune akasiyana ejenti senge mabhakitiriya, mafuru, fungi uye nevamwe. Izvo pasina mubvunzo zvakaita kuti ive mhando ye yekona yekona yekutsvaga kwesainzi, kunyanya muzvidzidzo zvekuzvidzivirira uye kudzivirira kwezvisikwa.

Mumunda we genetics inoitawo basa rakakosha kwazvo, nekuda kwekushomeka kwayo kwe immune system inozvizivisawo sechinhu chakakosha mumamorera marabhoritari epasi. Kukosha kwayo kwakakosha zvekuti kwakashandiswa kugadzira chirwere chekuyedza kurwisa hutachiona hune njodzi hweEbola. Masayendisiti anofananidza Nicotiana nembeva dzevasina kupfeka.

Chimwe chinhu chakakosha chemuti uyu ndechekuti hunhu hwayo hunogona kuendeswa kune zvimwe zvirimwa. Saka vaongorori vanogona kutsvaga nzira yekushandura dzimwe mhando dzemiti kuva mbeve dzisina kupfeka mbeva dzekutsvaga. Saka, nenzira imwechete se mbeva dzinoshandiswa mukutsvaga kenza, Nicotiana nemhando dzayo dzemiriwo dzinogona kumhanyisa kutsvagisa mundima yekurima.

Imwe yemabhenefiti emuti uyu kushandiswa kwayo mukugadzira mapuroteni anodzokorora, anosanganisira biopharmaceuticals, majekiseni uye biomaterials. Uye zvakare, mhodzi dzayo hombe dzinoigadzira mhando yakakwana yekutengesa Seye biofactory, nekuti saizi yembeu yayo inoipa kwakawanda kuita mukugadzirwa kwemishonga.
