This study was based on the soy protein isolates as raw materials. Chemical modification( acetylation,succinylation ,phosphorylation and urea modification) of SPI were used to improve adhesive strength and water resistance of SPI-based plywood adhesives. Then two modified ways combined were applied to SPI and their adhesive properties were studied. This research also characterized the thermal and adhesive properties of two major soy protein components 7S conglycinin and 11S glycinin after urea modification. Finally, the mechanism of improving SPI's adhesive properties was preliminarily discussed.

A trivalent plant expression vector containing Bt cry1Ah gene, cry1Ie gene and glyphosate-tolerant 2mG2-epsps gene was constructed, glyphosate isopropylamine salt as a screening agent, 2mG2-epsps gene as a selectable maker gene. The vector was transfer into maize immature embryonic calli by microprojectile bombardment, and 69 T0 generation plants were obtained. PCR analysis showed that 17 plants had the integration of insect-resistant cry1Ah, cry1Ie gene and glyphosate-tolerance 2mG2-epsps gene.

同时构建了含有Bt cry1Ah和cry1Ie基因和耐草甘膦2mG2-epsps基因的三价植物表达载体，通过基因枪轰击法转化玉米愈伤组织，以2mG2-epsps为筛选标记基因，以草甘膦异丙胺盐作为筛选剂，获得T0代转化植株69株，PCR检测结果表明：有17株已完整的整合有抗虫基因cry1Ah、cry1Ie和耐草甘膦基因2mG2-epsps的3个目的基因，RT-PCR分析外源基因可以正确转录，已获得结实转基因植株。
