Transcription profiling of Gerbera petals of developmental stages 2, 4, 6, 7, 8, and 9 vs a reference sample to identify transcriptional changes in petal development


ABSTRACT: Gerbera petals of inflorescence developmental stages 2, 4, 6, 7, 8, and 9 were compared against a reference sample that included same amount of mRNA from stages 1-11. Alltogether six comparisons were done each including two biological replicates with 3 technical replicates resulting alltogether 36 hybridizations. At least one of each biological replicate was dyeswap hybridization. This experiment was done in order to profile transcriptional changes that occur in petals from stage where they still divide until senescence of the cells. Developmental stages have been characterized by Helariutta et al. (1995).

Integrated regulation of the type III secretion system and other virulence determinants in Ralstonia solanacearum.

In many plant and animal bacterial pathogens, the Type III secretion system (TTSS) that directly translocates effector proteins into the eukaryotic host cells is essential for the development of disease. In all species studied, the transcription of the TTSS and most of its effector substrates is tightly regulated by a succession of consecutively activated regulators. However, the whole genetic programme driven by these regulatory cascades is still unknown, especially in bacterial plant pathogens  ...[more]
