Abstract

Bioenergy is the reduction of carbon via photosynthesis. Currently, this energy is harvested as liquid fuel through fermentation. A major concern, however, is input cost, in particular use of excess water and nitrogen, derived from an energy-negative process, the Haber-Bosch method. Furthermore, the shortage of arable land creates competition between uses for food and fuel, resulting in increased living expenses. This review seeks to summarize recent knowledge in genetics, genomics, and gene expression of a rising model species for bioenergy applications, sorghum. Its diploid genome has been sequenced, it has favorable low-input cost traits, and genetic crosses between different cultivars can be used to study allelic variations of genes involved in stem sugar metabolism and incremental biomass.
