The Institute of Cereal and Oil Crops, in collaboration with the College of Agriculture at Hebei Agricultural University and Hebei Normal University of Science and Technology, has published two research papers in internationally renowned journals "Plant, Cell&Environment" (IF=7.9, Top Journal of the 1st district of the Chinese Academy of Sciences) and "BMC Plant Biology" (IF=4.5, Top Journal of the 2nd district of the Chinese Academy of Sciences), clarifying the signaling regulatory pathways and mechanisms of TaPYR10 and TaNF-YB2 genes in wheat response to drought stress, providing a new perspective for further understanding the molecular mechanisms of wheat drought resistance.

The article "TaPYR10 Coordinates Abscisic Acid Sensing and Downstream Gene Activation to Deliver Drought Resilience and Yield Benefits in Wheat" published in "Plant, Cell&Environment" showed that under drought stress, the abscisic acid receptor gene TaPYR10 enhances wheat drought resistance and yield by regulating stomatal movement, accumulation of osmoregulatory substances, and clearance of reactive oxygen species.

In the article titled "Transcription factor TaNF-YB2 interactions with partners TaNF-YA7/YC7 and transcriptionally activating distinct stress defensive genes to modulate drought tolerance in T. aestivum" published in "BMC Plant Biology", the team further discovered that the nuclear factor Y family gene TaNF-YB2 enhances wheat drought tolerance by activating downstream stress resistant genes; And the dominant haplotype of this gene has a distribution frequency of over 40% among the main wheat varieties in North China, which can provide reference for the selection of drought resistant wheat resources.

The publication of the above two articles marks a breakthrough and progress in the integration of crop cultivation and molecular biology in the cultivation discipline of the Institute of Cereal and Oil Crops, laying the foundation for future research on crop molecular cultivation.
