Molecular networks regulating Arabidopsis seed maturation, after-ripening, dormancy and germination.
The transition between dormancy and germination represents a critical stage in the life cycle of higher plants and is an important ecological and commercial trait. In this review we present current knowledge of the molecular control of this trait in Arabidopsis thaliana, focussing on important components functioning during the developmental phases of seed maturation, after-ripening and imbibiti...
متن کاملHFR1 sequesters PIF1 to govern the transcriptional network underlying light-initiated seed germination in Arabidopsis.
Seed germination is the first step for seed plants to initiate a new life cycle. Light plays a predominant role in promoting seed germination, where the initial phase is mediated by photoreceptor phytochrome B (phyB). Previous studies showed that phytochrome-interacting factor1 (PIF1) represses seed germination downstream of phyB. Here, we identify a positive regulator of phyB-dependent seed ge...
متن کاملDifferential induction of Orobanche seed germination by Arabidopsis thaliana.
Parasitic plants, including the root holoparasites Orobanche spp., cause devastating damage to crops worldwide. Arabidopsis thaliana (L.) is widely used an amenable model for the study of plant biology, including plant-pathogen interactions. Bringing the two plants together in a controlled system will enable the study of the molecular and genetic basis involved in host-parasitic plant interacti...
متن کاملThe Significance of Hydrogen Sulfide for Arabidopsis Seed Germination
Hydrogen sulfide (H2S) recently emerged as an important gaseous signaling molecule in plants. In this study, we investigated the possible functions of H2S in regulating Arabidopsis seed germination. NaHS treatments delayed seed germination in a dose-dependent manner and were ineffective in releasing seed dormancy. Interestingly, endogenous H2S content was enhanced in germinating seeds. This inc...
متن کاملEffect of AtR8 lncRNA Partial Deletion on Arabidopsis Seed Germination
Long non-coding RNAs(lncRNAs) are longer than 200 nucleotides in length, which largely exist in organism and have various biological functions. AtR8 RNA is a lncRNA transcribed by RNA polymerase III in Arabidopsis. Northern blot analysis indicates that AtR8 RNA is abundant during seed germination. AtR8 RNA partial deletion reduces seed germination under normal culture condition. SA treatment in...
