摘要

甘蔗(Saccharum spp.)因其高糖产量和高生物量而成为重要的生物能源作物。生物燃料的生产效率取决于细胞壁组成,而细胞壁组成会影响生物质的消化率和发酵。细胞壁是由生物合成产物聚合形成的,如纤维素、半纤维素和木质素,并由调节因子和酶修饰。蛋白质组学通过鉴定关键蛋白,提高了我们对细胞壁重塑的理解。利用拟南芥(Arabidopsis thaliana)、毛杨(Populus trichocarpa)和短茅(Brachypodium distachyon)等模式生物进行比较研究,揭示了可以改善甘蔗生物能量性状的候选基因和蛋白质组。主要发现包括参与木质素沉积、纤维素生物合成和细胞壁结构成分的蛋白质,以及转录水平的调节机制。功能基因组学和蛋白质组学的进一步整合可以帮助开发具有更高生物量、更低抗性和更高糖化效率的甘蔗品种,促进可持续的木质纤维素生物燃料生产。本文综述了近年来的研究成果,并讨论了基因操作和蛋白质组学在提高甘蔗作为生物能源作物方面的潜力。

Proteomics-Based Genetic Regulation of Sugarcane Cell Wall Biosynthesis for Bioenergy Applications

Sugarcane (Saccharum spp.) is a key bioenergy crop due to its high sugar yield and biomass. Biofuel production efficiency depends on cell wall composition, which affects biomass digestibility and fermentation. Cell walls are formed by the polymerization of biosynthetic products, such as cellulose, hemicellulose, and lignin, and modified by regulatory factors and enzymes. Proteomics has advanced our understanding of cell wall remodelling through the identification of key proteins. Comparative studies using model organisms such as Arabidopsis thaliana, Populus trichocarpa, and Brachypodium distachyon have revealed candidate genes and proteomes that can improve sugarcane’s bioenergy traits. Key discoveries include proteins involved in lignin deposition, cellulose biosynthesis, and structural components of the cell wall, alongside regulatory mechanisms at the transcriptional level. Further integration of functional genomics and proteomics can help develop sugarcane varieties with higher biomass, lower recalcitrance, and greater saccharification efficiency, facilitating sustainable lignocellulosic biofuel production. This paper reviews recent findings and discusses the potential for genetic manipulation and proteomics in enhancing sugarcane as a bioenergy crop.

期刊介绍: The journal Sugar Tech is planned with every aim and objectives to provide a high-profile and updated research publications, comments and reviews on the most innovative, original and rigorous development in agriculture technologies for better crop improvement and production of sugar crops (sugarcane, sugar beet, sweet sorghum, Stevia, palm sugar, etc), sugar processing, bioethanol production, bioenergy, value addition and by-products. Inter-disciplinary studies of fundamental problems on the subjects are also given high priority. Thus, in addition to its full length and short papers on original research, the journal also covers regular feature articles, reviews, comments, scientific correspondence, etc.
