Abstract

Energy cane has been identified as an ideal crop for the sustainable production of biofuels due to its large amounts of lignocellulosic biomass. However, biochemical and molecular characteristics of energy cane have not yet been reported. The current study investigates polymorphism of simple sequence repeats in expressed sequence tags (Est-SSR loci) of energy cane clones PRBIO 172 and PRBIO 130 and of sugarcane varieties CTC 9001, CTC 9003, and RB935744, which permits a direct association between genes for specific proteins and enzymes and traits of agronomic interest. Genetic identity was observed in SSRs associated with loci EstA-68 and EstB-130 of the three sugarcane varieties and two energy cane clones. The basic contribution of our study was the identification of the polymorphic Est-SRR loci as targets to assess molecular and biochemical divergences of enzymes between sugarcane and energy cane, as well as between the two energy cane clones.

使能源甘蔗不同于甘蔗栽培品种的分子标记

由于含有大量木质纤维素生物质，能源甘蔗被认为是可持续生产生物燃料的理想作物。然而，能源甘蔗的生物化学和分子特征尚未见报道。本研究调查了能源甘蔗克隆 PRBIO 172 和 PRBIO 130 以及甘蔗品种 CTC 9001、CTC 9003 和 RB935744 的表达序列标签（Est-SSR 位点）中简单序列重复的多态性，这使得特定蛋白质和酶的基因与农艺学感兴趣的性状之间有了直接联系。在与三个甘蔗品种和两个能源甘蔗克隆的基因座 EstA-68 和 EstB-130 相关的 SSR 中观察到了遗传一致性。我们研究的基本贡献是确定了多态的 Est-SRR 位点，作为评估甘蔗和能源甘蔗之间以及两个能源甘蔗克隆之间酶的分子和生化差异的目标。

期刊介绍： Plant Gene publishes papers that focus on the regulation, expression, function and evolution of genes in plants, algae and other photosynthesizing organisms (e.g., cyanobacteria), and plant-associated microorganisms. Plant Gene strives to be a diverse plant journal and topics in multiple fields will be considered for publication. Although not limited to the following, some general topics include: Gene discovery and characterization, Gene regulation in response to environmental stress (e.g., salinity, drought, etc.), Genetic effects of transposable elements, Genetic control of secondary metabolic pathways and metabolic enzymes. Herbal Medicine - regulation and medicinal properties of plant products, Plant hormonal signaling, Plant evolutionary genetics, molecular evolution, population genetics, and phylogenetics, Profiling of plant gene expression and genetic variation, Plant-microbe interactions (e.g., influence of endophytes on gene expression; horizontal gene transfer studies; etc.), Agricultural genetics - biotechnology and crop improvement.
