The development of green energy is important to mitigate global warming. Jatropha ( L.) is a promising candidate for the production of alternative biofuel, which could reduce the burden on the Earth's resources. Jatropha seeds contain a large quantity of lipids that can be used to produce biofuel, and the rest of the plant has many other uses. Currently, techniques for plant genetic transformation are extensively employed to study, create, and improve the specific characteristics of the target plant. Successful transformation involves the alteration of plants and their genetic materials. The aim of this study was to generate Jatropha plants that can support biofuel production by increasing their seed size using genes found via the rice FOX-hunting system. The present study improved previous protocols, enabling the production of transgenic Jatropha in two steps: the first step involved using auxins and dark incubation to promote root formation in excised shoots and the second step involved delaying the timing of antibiotic selection in the cultivation medium. Transgenic plants were subjected to PCR analysis; the transferred gene expression was confirmed via RT-PCR and the ploidy level was investigated. The results suggest that the genes associated with larger seed size in , which were found using the rice FOX-hunting system, produce larger seeds in Jatropha.
发展绿色能源对于缓解全球变暖至关重要。麻风树(Jatropha (L.))是生产替代生物燃料的一个有前景的候选植物,这可以减轻地球资源的负担。麻风树种子含有大量可用于生产生物燃料的脂质,并且植株的其他部分还有许多其他用途。目前,植物遗传转化技术被广泛用于研究、创造和改善目标植物的特定特性。成功的转化涉及植物及其遗传物质的改变。本研究的目的是通过使用通过水稻FOX-hunting系统发现的基因来增加种子大小,从而培育出能够支持生物燃料生产的麻风树植株。本研究改进了先前的方案,实现了分两步生产转基因麻风树:第一步是使用生长素和暗培养来促进离体芽生根,第二步是推迟在培养基中进行抗生素筛选的时间。对转基因植株进行了PCR分析;通过RT-PCR确认了转移基因的表达,并研究了倍性水平。结果表明,利用水稻FOX-hunting系统发现的与水稻中较大种子大小相关的基因,在麻风树中产生了更大的种子。
