Genome-wide characterization and expression analysis of geranylgeranyl diphosphate synthase genes in cotton (Gossypium spp.) in plant development and abiotic stresses.

The GGPPS genes are evolutionary conserved and might be involve in different developmental stages and stress response. Some potential key genes (e.g. GhGGPP4, GhGGPP9, and GhGGPP15) were suggested for further study and provided valuable source for cotton breeding to improve fiber quality and resistant to various stresses.
