Kinetin yog thawj zaug cais los ntawm Miller thiab Skoog et al. ua cov khoom sib xyaw los ntawm autoclaved herring phev DNA uas muaj kev faib tawm ntawm tes. Nws tau muab lub npe kinetin vim nws muaj peev xwm ua kom muaj kev sib faib ntawm tes, yog tias auxin nyob hauv nruab nrab.
Leej twg nrhiav tau kinetin?
Cytokinins tau tshawb pom los ntawm F Skoog, C Miller, thiab cov neeg ua haujlwm sib koom ua ke thaum xyoo 1950 yog yam uas txhawb kev faib cell (cytokinesis). Thawj cytokinin pom yog ib qho adenine (aminopurine) derivative hu ua 'kinetin' (6-furfuryl aminopurine), uas tau raug cais tawm ua cov khoom lag luam DNA degradation.
Leej twg txheeb xyuas Crystaletized kinetin ua ntej?
4.1 Taw qhia. Kwv yees li 50 xyoo dhau los, cov tshuaj lom neeg uas txhawb nqa kev loj hlob ntawm tes hauv cov kab lis kev cai luam yeeb yog thawj zaug purified thiab crystallized los ntawm Skoog thiab nws cov neeg koom tes los ntawm autoclaved herring phev DNA extracts.
Yog nrhiav tau los ntawm Skoog Miller li al?
Cytokinins yog ib pawg sib txawv ntawm N6-substituted purine derivatives muaj peev xwm inducing cog cell faib. Qhov kev tshawb pom ntawm cytokinins los ntawm Folke Skoog thiab cov npoj yaig hauv xyoo 1950 tau pib tsom mus rau kinetin, cov khoom sib xyaw ua ke tau los ntawm autoclaved salmon phev DNA (Miller et al., 1955).
Kinetin Chav Kawm 11 yog dab tsi?
Kinetin yog cov khoom siv hauv cell faib hauv cov nroj tsuag thiab zoo ib yam li kinin. Nws yog cov tshuaj hormones cog uas pab hauv kev faib cov cell. Cov lus teb tiav: Kinetin yog a cytokinin uas pab cov nroj tsuag kom loj hlob.
