Expression of candidate marker genes of sugar starvation is upregulated in growth-suppressed parthenocarpic cucumber fruit. Novel gene markers for sugar starvation in growth-suppressed cucumber fruit.

To examine the physiological change in the growth suppression and abortion of parthenocarpic cucumber fruit, the expression of candidate marker genes of sugar starvation in relation to growth activity was examined. Fruits that failed to start exponential growth seemed to eventually abort. Hexose concentration of fruits was low in growth-suppressed fruit and increased in normally growing fruit consistent with the vacuolization.

The expression of a candidate cucumber fruit sugar starvation marker gene is enhanced in malformed fruit induced by salinity.

The cucumber ( L.) gene () was suggested to be a good marker gene for sugar starvation in fruit. The expression of this gene in fruits is dramatically upregulated in plants that have suffered either complete defoliation or prolonged darkness.

Genetic engineering and metabolite profiling for overproduction of polyhydroxybutyrate in cyanobacteria.

Genetic engineering and metabolite profiling for the overproduction of polyhydroxybutyrate (PHB), which is a carbon material in biodegradable plastics, were examined in the unicellular cyanobacterium Synechocystis sp. PCC 6803. Transconjugants harboring cyanobacterial expression vectors that carried the pha genes for PHB biosynthesis were constructed.

Expression of CsSEF1 gene encoding putative CCCH zinc finger protein is induced by defoliation and prolonged darkness in cucumber fruit.

To find a marker gene for photoassimilate limitation in cucumber fruit, genes induced in young fruit by total defoliation were cloned using the subtraction method. Almost every clone matched perfectly to a member of cucumber unigene ver. 3 of the Cucurbit Genomics Database.
