Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo.This is a pertinent stage in the plant life cycle that is followed by dormancy and germination. [1]
[6] [7] A plant lacking in phosphoglucomutase (pgm), for example, is a starchless mutant plant, thus preventing the settling of the statoliths. [8] This mutant shows a significantly weaker gravitropic response as compared to a non-mutant plant. [8] [9] A normal gravitropic response can be rescued with hypergravity. [9]
