摘要：

Expression of genes encoding the major Zea mays embryo globulins was examined in the maize precocious germination viviparous (vp) mutants. Comparison of globulin protein profiles of precociously germinating mutant embryos with those of normally germinating mature embryos revealed substantial differences with respect to the proteins encoded by the Glb1 gene. Analysis of Glb 1 transcript levels in vp/vp embryos suggests that these mutants do not fully switch from a program of embryo maturation to one of germination. These preliminary studies indicate that the vp mutants provide an excellent system for the study of embryo maturation in maize. We also provide evidence for the positive regulation of Glb1 expression by the plant growth regulator abscisic acid.
