Anti-sense expression vector of starch branch enzyme gene was transformed into maize inbred lines by Agrobacterium tumefaciens and the conditions of Agrobacterium tumefaciens transforming system were studied(EHA105 strain vibrates 20h,concentration of fermenting liquor was OD 0.5～0.6,infection time was 25 min).
RNA interference expression vector of starch branch enzyme gene was transformed into maize inbred lines by Agrobacterium tumefaciens and the conditions of Agrobacterium tumefaciens system were studied.
利用农杆菌(Agrobacterium tum efaciens)介导将淀粉分支酶基因RNA干涉表达载体转入玉米自交系中,并对农杆菌转化系统的条件进行研究。
Activities of ADPG pyrophosphorylase, soluble starch synthase and starch branching enzymes increased first and then fell down. Different varieties had different enzyme activities at the same filling stage and differed in the time when enzyme activity reached a peak value.
Among them, AP1280-EcoRV was the tag of Agp gene, RB2504B, RB3174, RB3828 and RB10420-ACCⅡ were tags of Rbe1 gene, RB1062 and RB10637 were tags of Rbe3 gene, and Iso5980B and R114/113 were tags of Iso and Pul genes respectively.
The highest activity of the starch-branching enzyme (Q-enzyme) in the grains of both high-starch lines appeared on 23 DAP, but that of both low-starch inbred lines showed double-peak curves, the peaks being at 15-20 DAP and 30-35 DAP.
Linkage localization of the starch branching enzyme I (Q-enzyme I) gene in rice
Linkage mapping of starch branching enzyme III in rice (Oryza sativa L.) and prediction of location of orthologous genes in othe
The chromosomal position of Starch Branching Enzyme III (SBEIII) was determined via linkage to RFLP markers on an existing molecular map of rice (Oryza sativa L.).
Characterisation of a gene encoding wheat endosperm starch branching enzyme-I
The following characteristics of the process were studied using this model: number-average, weight-average, and sedimentation-average degrees of polymerization and branching factor.
Biotin is recognized as an elongation factor and arginine as a branching factor in vegetative and reproductive hyphae.
We consider the process on a finite subtree, namely the rooted tree of depth h and branching factor d, and relate the behaviour of the process on the infinite tree to its behaviour on the finite tree for large h.
Space performance is affected by the branching factor during search.
Reducing this branching factor depends on the existence of 'nice' subclasses of the constraint domain.
