1.Qhov kev hloov pauv ntawm kev ua haujlwm ntawm cov enzymes cuam tshuam nrog carbohydrate metabolism yog ib qho tseem ceeb rau qos yaj ywm txias-induced sweetening (CIS).Ib tug tshiab RING ntiv tes gene SbRFP1 tau cloned thiab nws qhia tau pom tias yog txias-inducible nyob rau hauv qos tubers ntawm CIS-resistant genotypes.Kev hloov pauv ntawm SbRFP1 hauv cov qos yaj ywm tau lees paub nws lub luag haujlwm hauv inhibiting β-amylase thiab invertase kev ua haujlwm, uas yog li ua rau qeeb cov hmoov txhuv nplej siab thiab sucrose degradation thiab tsub zuj zuj ntawm txo cov suab thaj hauv cov tubers txias.Cov kev tshawb pom no qhia tau hais tias SbRFP1 tuaj yeem ua haujlwm tsis zoo ntawm BAM1 thiab StvacINV1 kom txo qis cov piam thaj hauv cov txheej txheem ntawm qos yaj ywm CIS.
2.Lub hom phiaj ntawm txoj haujlwm no yog los kawm txog kev cuam tshuam ntawm chav ua noj ntawm pectin methylesterase (PME) thiab endogenous α- thiab β-amylase cov dej num hauv cov ntaub so ntswg sib txawv (cortex thiab pith) ntawm cov qos yaj ywm nyoos thiab kub-kho cv.Agria.Peb qhov kub ua noj sib txawv tau xaiv (55, 70 thiab 85 ° C).Rau txhua qhov kev sim ua noj, lub sijhawm ntsuas kub tau raug kaw thiab qhov ntsuas ntawm qhov ua noj tau qhia raws li qhov ua tau zoo.Steam ua noj ua rau muaj txiaj ntsig zoo rau PME ntawm 55 ° C thiab txo nws cov haujlwm ntawm qhov ntsuas kub kawg (85 ° C) , nrog rau qhov siab tshaj plaws hauv lub cortex (0.3745 ± 0.0007 µmol galacturonic acid (GA) g(-1) tshiab yuag (FW) min(-1)) piv nrog pith (0.2617 ± 0.0012 µmol GA g(-1) FW feeb (-1)).Lub xub ntiag ntawm tshav kub-labile thiab tshav kub-ruaj khov isoforms ntawm PME hauv cov qos yaj ywm cov ntaub so ntswg kuj tau xav.Kev kho cua sov los ntawm chav ua rau muaj qhov txo qis hauv endogenous α- thiab β-amylase cov dej num hauv ob qho tib si cov ntaub so ntswg piv nrog cov qos yaj ywm nyoos rau, txawm tias tsis muaj kev ua kom tiav.Cov hmoov txhuv nplej siab-degrading enzymes kuj tau pom tias muaj qhov sib txawv hauv cov tuber nyoos.Steam ua noj cuam tshuam rau ntau txoj hauv kev uas tau txheeb xyuas qhov seem enzymatic hauv cov ntaub so ntswg ntawm qos yaj ywm cv.Agria.Kev tshawb fawb ntxiv yog xav tau kom paub meej tias cov txiaj ntsig tau txais.
