从致瘤农杆菌(Agrobacterium tumefaciens)的15个菌系中筛选出7个对大豆致瘤效果较好的菌系。找出了大豆结瘤较好的条件。对野生大豆(Glycine soja)、半野生大豆(G.gracilis)和栽培大豆(G.max)的1553个基因型做了引瘤实验,从中筛选出94个结瘤基因型。从瘤组织中诱导出脱菌的愈伤组织。生化鉴定证明,上述瘤来源的愈伤组织中有一部分含有胭脂碱。它们分属于野生大豆、半野生大豆和栽培大豆。成功地实现了基因转移。

223 genotypes which can form tumors with T-DNA have been screened from 627 genotypes, of three species of Glycine with different protein content, by infection with strains of Agrobacterium tumefaciens. Among 223 genotypes, 4 of cultivated soybean (G. max), 23 of semi-wild soybean (G. gracilis) and 19 of wild soybean (G. soja) contain protein at 43.00-45.52%, 44.00-49.55% and 48.00-51.79% respecti-vely.

223 genotypes which can form tumors with T-DNA have been screened from 627 genotypes, of three species of Glycine with different protein content, by infection with strains of Agrobacterium tumefaciens. Among 223 genotypes, 4 of cultivated soybean (G. max), 23 of semi-wild soybean (G. gracilis) and 19 of wild soybean (G. soja) contain protein at 43.00-45.52%, 44.00-49.55% and 48.00-51.79% respecti-vely. The bacteria free calli were obtained from tumor tissues by means of tissue culture. Biochemical detection showed that partial calli derived from tumor tissues of three species mentioned above contain T-DNA of Ti plasmid. Cell lines of the calli with T DNA have been established by using liquid culture. Up to present, 50 generations of the cell lines have been propagated and the nopaline synthetase gene is integrated stably in the genomes of soybeans. Chromosome number of the cell lines is normal, 2n=40, basically. This demonstrated that these cell lines are stable ones containing T-DNA. This is a good beginning for transferring high protein gene by using Ti plasmid.

通过农杆菌(Agrobacterium tumefaciens)致瘤,从大豆属三个种的蛋白质含量不同的627份种质资源中,筛选出致瘤材料223份。其中蛋白质含量在43.00—45.52%的栽培大豆(Glycine max)品种4份;蛋白质含量在44.00—49.55%的半野生大豆(Glycine gracilis)类型23份;蛋白质含量在48.00—51.79%的野生大豆(Glycine soja)类型19份。通过组织培养,从瘤组织中得到了脱菌的愈伤组织。生化检测表明,3个种的大豆瘤来源的部分愈伤组织含有T—DNA。并通过液体培养,建立了含T—DNA的细胞系。现已培养50多代,胭脂碱合成酶基因仍然稳定地整合在大豆基因组中,其染色体数为2n=40,表明是含T—DNA的稳定的细胞系。为基因转移打下了良好的基础。 T_1质粒作为植物基因工程的载体受到了广泛的重视,它的载体功能是通过擦伤感染致瘤的过程进入植物细胞来实现的,因此,通过致瘤反应筛选出理想的受体显得非常重要。我们对大豆属的致瘤反应曾作过一些报道,为了充分利用我国大豆的丰富资源,选育出高蛋白品种,我们进行了基因转移的高蛋白受体系统的研究,本文报道这些研究的初...

Taking Harbin natural day length as control,the performance of growthand development of 10 varieties of G.soja and 4 varieties of G.gracilis underthree shortday treatments can be shown as follows:(1)Varieties of G.soja and G.gracilis under all short-day treatmentperformed earlier blooming habit and shorter plants.This showed that suchvarieties are with distinct short-dayhabit.Response of the varieties to the 3treatments after the appearance of the first pair of true leaves,the beginingof sensitive photoperiodic stage,showed that effect of short day treatment for10 days during the earlier stage is less than that during the later stage.Treatment for 20 days was more effective than that for 10 days.(2)Under short day treatment,days from flowering to maturity of theaccessions from Heilongjiang and Jilin provinces became less,while days ofthose from places south of Jilin and Liaoning provinces became more,but theflowering date became significantly earlier though the later vegetative growthbecame prolific and plants matured later.This is due to that short-day habitof accessions from places of lower latitude is more stronger.(3)Under short-day treatment,the plants simultaneously became shorterand earlier.Response of wild and semi-wild soybeans to short-day treatmentdid not manifest on variation of number of branches and number of nodes onmain stems,because such soybeans are heavily branched and with vine typegrowth habit.Weight of the whole vegetative part may be an appropriate indexfor such response.(4)The effect of short-day treatment (promotion of earlier flowering andinduction of shorter plant) is significantly correlated with the latitude ofplaces of origin of the accessions.Accessions from the lower latitude weremore typical on short-day habit than those from places of higher latitude.

以哈尔滨自然光照为对照,用扣暗箱方式,对全国春大豆区五个省份的10份野生和半野生大豆进行了不同的短日照处理。结果表明,各处理均表现出开花提早、植株变矮的短日照效应,其效应与纬度呈高度显著的负相关。开花到成熟的日数表现不如开花期那样有规律。经短日照处理后,吉林、辽宁以南的材料开花到成熟日数反倒会增加。
