Sections of developing rice seeds in parental genome balanced and unbalanced crosses showing endosperm and embryo development. a-d Sections of Nip2n × Nip2n developing seeds at 2 DAP a, 3 DAP b, 4 DAP c, and 5 DAP d. Endosperm (en) and embryo (em) are indicated by arrows. Endosperm is not cellularized until 3 DAP. Starch granules (black dots) can be seen in the cellularized endosperm. e-h Sections of Nip2n × TH4n developing seeds at 2 DAP e, 3 DAP f, 4 DAP g, and 5 DAP h. Endosperm is never cellularized. Embryo arrests at globular stage. i-l Sections of TH4n × Nip2n developing seeds at 2 DAP i, 3 DAP j, 4 DAP k, and 5 DAP l. Precocious cellularization of endosperm occurs at 2 DAP and stop growing at 4 DAP. Embryo appears to be enlarged at 5 DAP. m-p Sections of TH4n × TH4n developing seeds at 2 DAP m, 3 DAP n, 4 DAP o, and 5 DAP p. Development of endosperm and embryo is similar to that in Nip2n × Nip2n
