Plant growth regulator (PGR) crosstalk and interaction with the plant's genotype
and environmental factors play a crucial role in microspore embryogenesis (ME),
controlling microspore-derived embryo differentiation and development as well as
haploid/doubled haploid plant regeneration. The complexity of the PGR network
which could exist at the level of biosynthesis, distribution, gene expression or
signaling pathways, renders the creation of an integrated model of ME-control
crosstalk impossible at present. However, the analysis of the published data
together with the results received recently with the use of modern analytical
techniques brings new insights into hormonal regulation of this process. This
review presents a short historical overview of the most important milestones in
the recognition of hormonal requirements for effective ME in the most important
crop plant species and complements it with new concepts that evolved over the
last decade of ME studies.
