Project description:Mycorrhizal fungi colonize orchid seed and induce the germination. This so-called symbiotic germination is a critical developmental process in the lifecycle of all orchids. However, the molecular changes taking place during the orchid seed symbiotic germination still remains largely unknown. To better understand the molecular mechanism of orchid seed germination, we performed comparative transcriptomic and proteomic analysis on Chinese traditional medicinal orchid plants, Dendrobium officinale to explore protein expression change at the different developmental stages between asymbiotic and symbiotic germination and identify the key proteins regulated symbiotic germination of orchid seeds. iTRAQ analysis from 8 samples identified 2256 plant proteins, of which, 308 proteins were differentially expressed across three developmental stages within asymbiotic or symbiotic accession and 229 proteins are differentially expressed in the symbiotic germination compared to asymbiotic germination. 32 proteins are co-upregulated in both proteomic and transcriptomic level for symbiotic germination compared to asymbiotic germination. Our results revealed that symbiotic germination of D. officinale seeds probably shares the common signal pathway with asymbiotic germination during the early germination stage.

Project description:In most plants, germination begins with the reactivation of metabolism during water uptake by the desiccated seed. Notably, Pol II transcription is hypothesised not to be required for early germination, as seeds appear to initially rely on stored mRNAs produced during their maturation. Here, we show that efficient blocking of Pol II transcription completely stops germination in Arabidopsis seeds. Pol II activity is initiated early and is widespread, following expression and Pol II binding patterns established during seed drying. Our findings suggest that the earliest transcriptional phase relies on pre-existing protein factors. The transcriptional programme initiated during water uptake is robust across diverse imbibition conditions and in seeds matured at different temperatures, and is conserved in rapeseed (Brassica napus). Only after the successful completion of this initial phase and the passing of the translation-dependent checkpoint do seeds activate genes that lead to germination. Our results redefine the role of transcription in seed germination and highlight a conserved pattern of early transcriptional activation.
