additional information	OscFBP1 mutants (mutant allele oscfbp1-1 containing a Tos17 insertion in the second exon, and mutant allele oscfbp1-2 harbouring a T-DNA insertion in the third intron) exhibit markedly decreased photosynthetic rates and severe growth retardation with reduced chlorophyll content, which results in plant death. Analysis of primary carbon metabolites reveals both significantly reduced levels of sucrose, glucose, fructose and starch in leaves of these mutants, and a high accumulation of sucrose to starch in leaves of rice plants. In the oscfbp1 mutants, products of glycolysis and the TCA cycle are significantly increased. A partitioning experiment of 14C-labelled photoassimilates reveals altered carbon distributions including a slight increase in the insoluble fraction representing transitory starch, a significant decrease in the neutral fraction corresponding to soluble sugars and a high accumulation of phosphorylated intermediates and carboxylic acid fractions in the oscfbp1 mutants	Oryza sativa
