PNAS：植物经玉米基因增强后具生物燃料潜能

美国科研人员报告说，植物柳枝稷常用于生产生物燃料。经玉具生这让它们更容易分解成用于生产生物燃料的米基单糖，这些植物比缺乏Cg1基因的因增植物长出了更多的枝条并且在茎中储存了至多250%的淀粉，这些科研人员还能够从这些淀粉中提取葡萄糖而不需要对植物组织进行昂贵且耗费能源的强后预处理。含有Cg1的物燃柳枝稷可能成为生物燃料产业的一种改良的原料。

近日，料潜这具有一些优势：本来可能用于制造花和种子的植物资源被用于制造额外的淀粉，Cg1基因还能够转移到其他物种中，从而改善它们作为生物燃料作物的潜力。

Overexpression of the maize Corngrass1 microRNA prevents flowering, improves digestibility, and increases starch content of switchgrass

Biofuels developed from biomass crops have the potential to supply a significant portion of our transportation fuel needs. To achieve this potential, however, it will be necessary to develop improved plant germplasm specifically tailored to serve as energy crops. Liquid transportation fuel can be created from the sugars locked inside plant cell walls. Unfortunately, these sugars are inherently resistant to hydrolytic release because they are contained in polysaccharides embedded in lignin. Overcoming this obstacle is a major objective toward developing sustainable bioenergy crop plants. The maize Corngrass1 (Cg1) gene encodes a microRNA that promotes juvenile cell wall identities and morphology. To test the hypothesis that juvenile biomass has superior qualities as a potential biofuel feedstock, the Cg1 gene was transferred into several other plants, including the bioenergy crop Panicum virgatum (switchgrass). Such plants were found to have up to 250% more starch, resulting in higher glucose release from saccharification assays with or without biomass pretreatment. In addition, a complete inhibition of flowering was observed in both greenhouse and field grown plants. These results point to the potential utility of this approach, both for the domestication of new biofuel crops, and for the limitation of transgene flow into native plant species.
