...Laurel Russell; Victoria Larner; Smita Kurup; Susan Bougourd; Michael Holdsworth ABSTRACT Mutation of the COMATOSE locus in Arabidopsis results in a marked reduction in germination potential. Whilst the morphology of comatose ( cts ) embryos is not altered, physiological analysis reveals...

...Donna E. Fernandez ABSTRACT Precociously germinating Brassica napus (oilseed rape) embryos produce extra cotyledons or chimeric organs with sectors of cotyledon and leaf tissue, rather than leaves, at the shoot apex. To investigate this phenomenon in more detail, scanning electron microscopy...

... minute lag period in a process known as ‘erasure’. Here we show that cells that have completed the morphogenetic program and emerge from spore coats in the process of germination have also erased. In addition, the germi-nation-specific 270 gene family is expressed during induced dedifferentiation...
