Seed germination is a vital stage in the plant life-cycle that greatly contributes to plant establishment. Melatonin has been shown to promote seed germination under various environmental stresses; however, the mechanism remains largely underexplored. Here, we reported that melatonin antagonized abscisic acid (ABA) to promote seed germination by regulating ABA and gibberellic acid (GA3) balance. Transcriptomic analysis revealed that such a role of melatonin was associated with Ca ...[more]

Exogenous melatonin promotes rice seed germination under salinity through regulating reactive oxygen species and phytohormones

Project description:Melatonin plays a potential role in multiple plant developmental processes and stress response. However, there are no reports regarding exogenous melatonin promoting rice seed germination under salinity and nor about the underlying molecular mechanisms at genome-wide. Here, we revealed that exogenous application of melatonin conferred roles in promoting rice seed germination under salinity. The putative molecular mechanisms of exogenous melatonin in promoting rice seed germination under high salinity were further investigated through metabolomic and transcriptomic analyses. The results state clearly that the phytohormone contents were reprogrammed, the activities of SOD, CAT, POD were enhanced, and the total antioxidant capacity was activated under salinity by exogenous melatonin. Additionally, melatonin-pre-treated seeds exhibited higher concentrations of glycosides than non-treated seeds under salinity. Furthermore, exogenous melatonin alleviated the accumulation of fatty acids induced by salinity. Genome-wide transcriptomic profiling identified 7160 transcripts that were differentially expressed in NaCl, MT100 and control. Pathway and GO term enrichment analysis revealed that genes involved in the response to oxidative stress, hormone metabolism, heme building, mitochondrion, tricarboxylic acid transformation were altered after melatonin pre-treatment under salinity. This study provides the first evidence of the protective roles of exogenous melatonin in increasing rice seed germination under salt stress, mainly via activation of antioxidants and modulation of metabolic homeostasis.

SWI/SNF ATPase SPLAYED modulates ABA catabolism and GA biosynthesis in ABA-inhibition of seed germination

Project description:The phytohormone abscisic acid (ABA) promotes seed dormancy and inhibits seed germination and seedling development. It remains unclear how chromatin remodeling influences ABA responses. In the present study, an artificial microRNA targeting two Sucrose Non-Fermenting 2 (SNF2)-family chromatin remodeling ATPases, SPLAYED (SYD) and PHOTOPERIOD-INDEPENDENT EARLY FLOWERING1 (PIE1), was identified through unbiased forward genetic screenings of artificial microRNA (amiRNA)-expressing pooled seed libraries exhibiting ABA-insensitive seed germination. T-DNA insertional mutants of syd and pie1, along with amiRNA-expressing knockdown lines amiR-SYD and amiR-PIE1, confirmed that SYD, but not PIE1, is essential for promoting ABA-inhibition of seed germination. Transcriptome analyses revealed that the ABA catabolism gene CYP707A3 and the gibberellin (GA) biosynthesis genes GA20OX2, GA20OX3, GA3OX2, GA3OX3, and GA3OX4 were upregulated in amiR-SYD mutant seeds compared to control seeds under ABA treatment during germination. The ABA hyposensitivity observed in amiR-SYD mutants was reversed by treatment with uniconazole, an inhibitor of ABA catabolism and GA biosynthesis, suggesting that the reduced ABA sensitivity in amiR-SYD mutants results from increased ABA degradation and GA production. These findings demonstrate that the SYD-associated chromatin remodeling complex positively regulates ABA responses during seed germination, unlike its close homolog BRAHMA (BRM), which acts as a negative regulator of the ABA response.

Dynamics of protein phosphorylation during Arabidopsis seed germination

Project description:Seed germination is a major step of plant growth and development. It is critical for species competition and spreading capacity in ecosystems. In agrosystems, it eventually impacts crop growth and yield. To prevent unappropriated germination under environmental conditions that do not guarantee the establishment of a robust plantlet, seeds from temperate species are generally dormant at maturity. Dormancy is a physiological mechanism that blocks seed germination even under favorable conditions and dormancy release is therefore required prior to germination [1]. A range of environmental (e.g. temperature, light, oxygen availability) and endogenous (e.g. hormonal) signals regulate these processes and germination completion, i.e. the early emergence of embryo radicle from seed envelope, can be achieved only when promoting mechanisms overcome inhibiting processes [2]. In that sense, the balance between the two antagonistic hormones abscisic acid (ABA) and gibberellins (GA), that inhibit and stimulate seed germination, respectively, promotes either dormancy (high ABA and low GA contents) or germination (low ABA and high GA contents) [3]

NUP1 modulates proteasome based degradation of ABI5 in Nuclear Pore Complex region to regulate Arabidopsis seed germination

Project description:NUCLEOPORIN 1 (NUP1), a member of the Nuclear Pore Complex (NPC), is located on the inner side of the nuclear membrane. It is highly expressed in seeds; however, its role in seeds including germination has not been explored yet. Here, we identified an ABA hypersensitive phenotype of nup1 during germination. ABA treatment drastically changes the expression pattern of thousands of genes in nup1, including the major transcription factors (TFs) involved in germination, ABI3, ABI4, and ABI5. Double mutant analysis of NUP1 and these ABA-related genes showed that mutations in ABI5 can rescue the phenotype of nup1, suggesting that NUP1 acts upstream of ABI5 to regulate seed germination. ABI5, a negative regulator of germination was previously reported to be predominantly expressed in nucleus. Our subnuclear localization study indicates ABI5 is mostly localized in nucleoplasm. It is abundant in dry seeds and rapidly degraded during germination, but the details of its degradation site is unclear. Here, we found that NUP1 is physically associated with ABI5 and the 19S regulatory particle (RP) of the 26S proteasome near NPC. Mutation in NUP1 delayed the ABI5 degradation through its post-translation retention in nucleolus after abiotic stress treatment. Taken together, we propose, NUP1 anchors the proteasome to NPC and modulates Arabidopsis seed germination through proteasome-mediated degradation of ABI5 in the vicinity of NPC in nucleoplasm.

The calmodulin-like protein, CML39, is involved in regulating seed development, germination, and fruit development in Arabidopsis

Project description:In addition to the evolutionarily-conserved Ca2+ sensor, calmodulin (CaM), plants possess a large family of CaM-related proteins (CMLs). Using a cml39 loss-of-function mutant, we investigated the roles of CML39 in Arabidopsis and discovered a range of phenotypes across developmental stages and in different tissues. In mature plants, loss of CML39 results in shorter siliques, reduced seed number per silique, and reduced number of ovules per pistil. We also observed changes in seed development, germination, and seed coat properties in cml39 mutants in comparison to wild-type plants. Using radicle emergence as a measure of germination, cml39 mutants showed more rapid germination than wild-type plants. In marked contrast to wild-type seeds, the germination of developing, immature cml39 seeds was not sensitive to cold-stratification. In addition, germination of cml39 seeds was less sensitive than wild-type to inhibition by ABA or by treatments that impaired gibberellic acid biosynthesis. Tetrazolium red staining indicated that the seed-coat permeability of cml39 seeds is greater than that of wild-type seeds. RNA sequencing analysis of cml39 seedlings suggests that changes in chromatin modification may underlie some of the phenotypes associated with cml39 mutants, consistent with previous reports that orthologs of CML39 participate in gene silencing. Aberrant ectopic expression of transcripts for seed storage proteins in 7-day old cml39 seedlings was observed, suggesting mis-regulation of early developmental programs. Collectively, our data support a model where CML39 serves as an important Ca2+ sensor during ovule and seed development, as well as during germination and seedling establishment.

Comparative transcriptome analysis of wheat embryo and endosperm response to ABA and H2O2 stresses during seed germination

Project description:Wheat seed germination directly affects wheat yield and quality. The wheat grains mainly include embryo and endosperm, and both play important roles in seed germination, seedling survival and subsequent vegetative growth. ABA can positively regulate dormancy induction and then negatively regulates seed germination at low concentrations. H2O2 treatment with low concentration can promote seed germination of cereal plants. Although various transcriptomics and proteomics approaches have been used to investigate the seed germination mechanisms and response to various abiotic stresses in different plant species, an integrative transcriptome analysis of wheat embryo and endosperm response to ABA and H2O2 stresses has not reported so far. We used the elite Chinese bread wheat cultivar Zhenmai 9023 as material and performed the first comparative transcriptome microarray analysis between embryo and endosperm response to ABA and H2O2 treatments during seed germination using the GeneChip® Wheat Genome Array Wheat seed germination includes a great amount of regulated genes which belong to many functional groups. ABA/H2O2 can repress/promote seed germination through coordinated regulating related genes expression. Our results provide new insights into the transcriptional regulation mechanisms of embryo and endosperm response to ABA and H2O2 treatments during seed germination

Control of seed dormancy and germination by DOG1-AHG1 PP2C Phosphatase complex via binding to heme

Project description:Abscisic acid (ABA) regulates abiotic stress and developmental responses including regulation of seed dormancy to prevent seeds from germinating under unfavorable environmental conditions. ABA HYPERSENSITIVE GERMINATION1 (AHG1) encoding a type 2C protein phosphatase (PP2C) is a central negative regulator of the ABA response in germination; however, the molecular function and regulation of AHG1 remain elusive. Here we report that AHG1 interacts with DELAY OF GERMINATION1 (DOG1), which is a pivotal positive regulator in seed dormancy. DOG1 acts upstream of AHG1 and impairs the PP2C activity of AHG1 in vitro. Furthermore, DOG1 has the ability to bind heme. Binding of DOG1 to AHG1 and heme are independent processes but both are essential for DOG1 function in vivo. Our study demonstrates that AHG1 and DOG1 constitute an important regulatory system for seed dormancy and germination by integrating multiple environmental signals, in parallel with the PYL/RCAR ABA receptor-mediated regulatory system.

Dendrobium officinale seed symbiotic germination iTRAQ

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.
