• Small Grain and Dwarf 2, encoding an HD-Zip II family transcription factor, regulates plant development by modulating gibberellin biosynthesis in rice., 2019, Plant Sci.
• Regain flood adaptation in rice through a 14-3-3 protein OsGF14h., 2022, Nat Commun.

Genbank accession number

• High performance liquid chromatography assays showed that the endogenous GA1 level in the sgd2 mutant was dramatically decreased, and exogenous GA3 recovered the second leaf sheath to normal length
• Map-based cloning and complementation tests demonstrated that a 9 bp deletion in a homeodomain leucine zipper (HD-Zip) II family transcription factor was responsible for the sgd2 mutant phenotype
• Expression of SGD2 was pronounced in developing panicles, and its protein was localized in nucleus
• OsGF14h acts as a signal switch to balance ABA signaling and GA biosynthesis by interacting with the transcription factors OsHOX3 and OsVP1, thereby boosting the seeding rate from 13

• OSVP1~VP1, SGD2~OsHOX3, Regain flood adaptation in rice through a 14-3-3 protein OsGF14h., OsGF14h acts as a signal switch to balance ABA signaling and GA biosynthesis by interacting with the transcription factors OsHOX3 and OsVP1, thereby boosting the seeding rate from 13
