The “Domino effect” model of seed size regulation. Diagram represents progression of the major seed developmental events in SN and LGR. Upper and lower panels represent SN and LGR, respectively (as mentioned on the left of the diagram). S1–S5 represent five stages of seed development. Orange, red, green, violet, and blue bars represent progression of cell cycle, cellularization, endoreduplication, storage reserve accumulation, and PCD during seed development (as indicated in the color legend). Lines represent accumulation pattern of hormones during seed development in SN and LGR based on genes showing different expression pattern in the two genotypes. Pathways specific or preferential to S3 stage in LGR contributing to enhanced cell size have been mentioned between the dotted red lines below S3 stage. Comparable seed developmental stages have been connected with dotted gray lines
