Expression profiles of genes in rose petals responsive to dehydration

Cut rose flowers (Rosa hybrida), which are generally harvested at bud stage 2, are susceptible to dehydration stress resulting in failure of opening or abnormal flowering during postharvest handlings. These stresses would lead more than 30% marketing loss in rose flower industry. Thus, it is meaningful to investigate the molecular mechanisms underlining the dehydration tolerance in cut rose flowers. The differentially expressed genes (DEG) were explored by RNA-sequencing the rose petals dehydrated for 0- 24 h.
