Integrated multi-omics analysis of hormone regulatory networks and key genes involved in inflorescence development during flowering in Agropyron cristatum and Agropyron multiflorum

Agropyron cristatum and its variety, Agropyron cristatum var. pluriflorum, are important gramineous forages and wild relatives of wheat. The inflorescence morphology directly determines their yield potential. However, the molecular regulatory mechanism driving the formation of the high-yield inflorescence phenotype in Agropyron cristatum var. pluriflorum remains unclear.
