Cellulose waa polymerka dib loo cusboonaysiin karo ee ugu badan ee dhulka iyo qayb weyn oo ka mid ah gidaarka unugyada dhirta.Dhirta xididada xididada dhiigga, isku-xidhka cellulose-ka waxa kataliya unug weyn, xuubka plasma-localized cellulose synthase complex (CSC), oo loo arko qaab-dhismeedka rosette hexameric.Seddex nooc oo unugyo cellulose synthase (CESA) gaar ah ayaa looga baahan yahay isu-ururinta iyo shaqada CSC.Si kastaba ha ahaatee, qeexitaanka tirada ama stoichiometry ee CESA-yada gudaha CSC ayaa ah mid la fahmi karo.Daraasaddan, waxaan ku tusineynaa 1: 1: 1 stoichiometry ee u dhexeeya saddexda Arabidopsis thaliana secondry cell isozymes: CESA4, CESA7, iyo CESA8.Saamigan waxaa la go'aamiyay iyadoo la adeegsanayo hab fudud laakiin qurux badan oo tallaalka tireed iyadoo la adeegsanayo unugyada difaaca jirka ee isoform-ka iyo (35) heerarka borotiinka ee CESA kasta.Intaa waxaa dheer, stoichiometry equimolar-ka ee la arkay ayaa la ogaaday inay ku go'an tahay dhidibka jirida, taas oo u taagan korriinka korriinka.Natiijooyinkayagu waxay dhamaystirayaan falanqaynta spectroscopic ee dhawaanta tilmaamaysa 18-silsilad cellulose microfibril.Isku soo wada duuboo, waxaanu soo jeedinaynaa in CSC ay ka kooban tahay hexamer oo ah trimers CESA firfircoon, oo CESA kasta ay ku jirto xaddi isku mid ah.Helitaankani waa horumar muhiim ah oo lagu fahmo sida CESA-yadu u dhexgalaan si ay u sameeyaan dhismooyin nidaam sare leh, kaas oo fure u ah go'aaminta microfibril cellulose iyo guryaha gidaarka unugga.
