Callus Induction in Endosperms from Maize Mutants with Different IAA Content
From the first successful in vitro culture of maize endosperm tissue, reported in 1949 (La Rue 1949), long-term cultures of callus derived from immature endosperms have been established from sweet corn varieties (Straus and La Rue 1954; Tamaoki and Ullstrup 1958), from starchy inbreds varieties (Shannon and Batey 1973) and from several endosperm mutants: ae, su2 (Shannon and Batey 1973), wx (Reddy and Peterson 1977), o2 (Manzocchi and Racchi 1986); endosperm cultures have been demonstrated suitable for metabolic studies, and have been employed for research on cell division and chromosome constitution (Boyer and Shannon 1974), starch synthesis (Chu and Shannon 1975) and an-thocyanins biosynthesis (Straus 1959; Racchi 1985).
