Abstract:In spite of the expansions of population and the climate problems associated with fossil fuel, petroleum, coal and nature gases are still the major energy sources for electricity production and transportation in our daily life. Developing biofuel from lingo-cellulosic biomass or byproduct from food processing industry is one possible solution that can help us develop sustainable energy sources without food safety concerns. Here we conducted a transcriptomic study on the transgressive segregation of the F2 population derived from a cross between Saccharum officinarum ‘LA Purple’ and Saccharum robustum ‘MOL5829’ to determine how hormone related genes and pathways are regulated in sugarcane with high biomass yield. We also studied the transcriptome of 5 tissue types for 5 Saccharum spontaneum accessions with variable chromosome numbers and ploidy levels, and revealed impacts of ploidy levels of genome on global gene expression and transcriptional mechanism of differences in autoploidy chromosomes numbers. Last but not least, we analyzed the transcriptomic data of different tissue types of domesticated pineapple F153 and its wild relative Ananas bracteatus CB5 to study the transcriptomic level mechanism of water regulation related aquaporin gene family and revealed the rhythm of aquaporin transcripts, which is possibly relevant to water use efficiency (WUE). These studies have helped us gain more insights of trancriptomic mechanisms of hormones, ploidy levels, and aquaporins in various potential biofuel feedstocks, and may be helpful for further improving their performances and properties.
