| Outline of Final Research Achievements |
The majority of rosulate Streptocarpus (Gesneriaceae) species initiate leaves from the petiolode and form a false rosette (excentric rosulates). On the other hand, some rosulates show centralized phyllotaxy (centric rosulates). To understand the leaf formation and related meristem activities, we investigate the underlying morphogenesis and genetic mechanisms.
The results of morphological analyses showed that a shoot apical meristem (SAM) is present in centric rosulates while excentric rosulates do not retain a SAM. Further, genetic resources were built for the non-model plant Streptocarpus using state-of the art NGS techniques: genome sequence data were obtained with DNAseq, transcriptome sequences were obtained with RNAseq, and genotype information to build the genetic map was obtained with RADseq. The obtained genetic resources provide the bases to start genetic analyses to isolate the genes regulating the shoot apical meristem formation and its evolution in the genus Streptocarpus.
