Research Abstract

I tested the effects of free air CO_2 enrichment(FACE) on OsSPS1 gene expression and biomass production using chromosome segment substituted line which carries Kasalath allele OsSPS1 [CSSL(SPS)]. OsSPS1 gene expression levels and the dry weight of culm were increased in CSSL(SPS) under FACE condition.
