From: MADS-box family genes in sheepgrass and their involvement in abiotic stress responses
Yeast two-hybrid assays of 11 MADS-box proteins of sheepgrass. Protein-protein interactions of (a) two A-class MADS-box proteins, (b) three B-class MADS-box proteins, and (c) three other classes of MADS-box proteins. Serial dilutions (105–101) of AH109 cells containing different plasmid combinations were grown on the selective medium plates SD/−Trp-Leu-His-Ade/3 mM 3-AT
