Embryos Prom Synergids

The synergids, which usually degenerate prior to or soon after double fertilization, are reported to give rise to embryos in Argentine mexicana, Tamarix erimids, Dioscorea composita. The synergid embryos grow along with the zygotic embryo in the embryo sac. In Najas major the synergid and the egg cell are fertilized and the resulting embryos resemble each other. Fertilization of the synergid is usually on account of entry of additional pollen tube in the embryo sac.

Sometimes the unfertilized synergid is also stimulated to divide and form an embryo like structure. In the normal course only the zygotic embryo attains maturity and the haploid or diploid synergid embryo degenerates.
