Summary of the relationships between three starch synthase (SS) isozymes in the rice endosperm. (1) Active SSIIa compensates for most of the function of SSI, particularly elongating amylopectin chains from the degree of polymerization (DP) of 6–7 to DP 8–12 (thick arrow). (2) The function of SSIIa could not be complemented by SSI or SSIIIa (dotted arrows). (3) Neither SSI nor SSIIa could compensate for the function of SSIIIa, which synthesizes amylopectin chains with DP > 35 (dotted arrows). (4) The function of SSI could not be complemented by SSIIIa (dotted arrow). This figure was obtained from Crofts et al. (2017a)
