| 4. | Whether the gene was transformed into the arabidopsis was confirmed by pcr - southern blotting , southern blotting and northern blotting . 1 . pcr - southern blotting showed that all kanamycin - tolerant plants had strong positive signals , and no signal was shown in wild type plants
Pcr结果扩增出1 . 4kb的特异性条带，表明sod2已整合进拟南芥中， pcr - southern进一步证实了pcr结果的正确性。 |
| 5. | Based on different regions , the drainage can be used to expand sand control belts of arbors , shrubs and grasses , to increase vegetation coverage of halosols deserts by salt - tolerant plants , or to set up protective belts of salt - tolerant plants around artificial oases
根据区域不同，利用农田排水拓展乔灌草防沙带、增加盐成土荒漠耐盐植被的盖度、使人工绿洲边缘的荒漠能够生长耐盐植物等都是农田排水资源化利用发展的方向。 |
| 6. | Choline dehydrogenase ( cdh ) isolated from escherichia coli , can help the expression of glycine betaine efficiently . to get some salt - tolerant plants , the cdh gene , mediated by agrobacterium , was transformed to the haploid of populus simoniixp . nigra
本实验以农杆菌( agrobacteriumtumefaciens )为介导进行遗传转化，将编码cdh的耐盐基因( bet - a )导入小黑杨( populussimonii p . nigra )单倍体植株( haploid )的基因组内，以期获得耐盐植株。 |
| 7. | Distribution , formation and characteristics of the saline - alkalized land in northeast china was systematically analyzed and agro - biological measures for management of saline - alkalized soil were illustrated , including cultivation of rice to wash down salts , cultivation practices , soil building practices , plantation of salt - tolerant plants and biological removal of alkali , etc . in the paper
特殊的气候、地形和水文地质等自然因素以及人类不合理的农业技术措施和社会生产活动等人为因素加剧了该区盐碱化发生、分布与演变。 |
| 8. | Ssmapkk transformations were screened on media with kanamycin ( 30mg / l ) . nineteen individual kanamycin resistant plants were obtained . t2 plants were checked for integration of foreign gene by counting ratio of the number of tolerant plants to the number of non - tolerant plants on selection medium with kanamycin ( 30mg / l )
将ssvp和ssmapkk的全长cdna分别克隆入植物表达载体pcambia1300和prok中，导入根瘤农杆菌gv3101后，由花浸泡法进行拟南芥遗传转化，转化ssvp盐地碱蓬ssop和ssmapkk基因的克隆与功能鉴定的拟南芥在含潮霉素（ 25mg ）的ms培养基上筛选，获得t ；代转基因植株。 |
| 9. | The enzyme 5 - enolpyuvyl - 3 - phosphoshikimic acid synthase ( epsp synthase ; ec2 . 5 . 1 . 19 ) , encoded by anoa locus , is a key enzyme present in microorganisms and plants where it has a function in the biosynthesis of aromatic amino acids . glyphosate ( n - phosphonomethyl - glycine ) is an effective non - selective , broad spectrum , postemergence herbicide , which has been shown to inhibit epsp synthase activity in a competitive manner . glyphosate tolerant plants can be mediated by either overproduction of the target enzyme or by the presence of an altered enzyme
植物和微生物芳香族氨基酸生物合成过程中的一个关键酶? ? 5 -烯醇丙酮莽草酸- 3 -磷酸合成酶( epspsynthase ； ec2 . 5 . 1 . 19 )由aroa基因编码，该酶受广谱灭生性、内吸传导型除草剂草甘膦的竞争性抑制，将epsp合成酶基因转入植物中可获得草甘膦耐受植株。 |
| 10. | Consequently , study on the mechanisms of salt - tolerance in plants and breeding of salt - tolerant plants has become a key issue in plant biology nowadays . as an important plant osmotic regulators , glycine betaine in plants , under the osmotic stress , can be accumulated in order to give the plants high salt - tolerance by reducing osmotic pressure and maintaining proteinic structure in cell
甘氨酸甜菜碱( glycinebetaine )是一种重要的调渗物质，在盐胁迫下有些植物能通过体内甘氨酸甜菜碱的积累保护细胞内蛋白质的结构和功能，降低细胞水势，从而来增加自身的耐盐能力。 |
