Peach Genome Offers Hints
For Better Biofuel Production, Study Says
A long-term genomic analysis of the common peach has revealed important insights into how scientists can improve the biofuel potential of other plant species
, including the fast-growing poplar tree, a new
study says. Three years after a team of scientists first released a draft description of the annotated peach genome, researchers make the case that the 265-million base sequence can be used to better understand the biology of related tree species, including the poplar, which like the peach is a member of the rosid superfamily. Writing in the journal Nature Genetics
, the scientists describe how a comparison of the peach’s genetics with six other fully sequenced plant species revealed metabolic pathways that lead to the formation of lignin, the durable biopolymer that holds plant cells together — and a barrier to breaking down biomass into fuels. “One gene we’re interested in is the so-called ‘evergreen’ locus in peaches, which extends the growing season,” said Daniel Rokhsar, a U.S. Department of Energy scientist who leads the sequencing of the peach genome. According to Rokhsar, that gene could be manipulated to increase the biomass accumulation of related species.
