- Description
- Medicago truncatula has readily accessible ovules that can be obtained from pods with morphological characteristics that correlate with embryos at different stages of development. In this chapter the expression pattern of a number of major transcription factors is examined, for M. truncatula embryogenesis, in relation to the characteristic morphology of the developing M. truncatula embryo. The embryo stages considered are the initial asymmetric zygotic division and early cell divisions, the development of the globular stage and the development of the shoot, root and procambium meristems of the heart stage embryo. The transcription factors belong to the AP2/ERF, ARF, HD-ZIP, KNOX, WOX, and WRKY gene families. While embryogenesis in M. truncatula and Arabidopsis thaliana have much in common, there are a number of M. truncatula genes that may have distinctive roles or different roles to their A. thaliana homologues. The significance of transcriptional regulation studies in somatic embryos (SE) for understanding zygotic embryogenesis (ZE) regulation is also considered.
