Project description:Fonio millet genome unlocks African orphan crop diversity for agriculture in a changing climate
| PRJEB36539 | ENA
Project description:Foxtail millet (Setaria italica L. P. Beauv) has been considered as a tractable model crop in recent years due to its short growing cycle, lower repetitive DNA, inbreeding nature, small diploid genome, and outstanding abiotic stress-tolerance characteristics. With modern agriculture often facing various adversities, it’s urgent to dissect the mechanisms of how foxtail millet responds and adapts to drought and stress on the proteomic-level.

Project description:Climate change is having a drastic impact on global agriculture. Indeed stress factors such as elevated temperature, drought and rising atmospheric CO2 reduce arable land surface, crop cultivation and yield and overall sustainable food production on earth. However, plants possess immense innate adaptive plasticity and a more in-depth understanding of the underlying molecular mechanisms is crucial to strategize for sustaining populations under worsening climate change. Brassinosteroids (BRs) are constitutive plant growth regulators that also control plant adaptation to abiotic stress. Downstream components of the BR biosynthetic pathway, BES1/BZR1 play central role in thermomorphogenesis, but involvement of the BR receptors is not well understood. Here, we show that the BRL3 receptor is essential for plant adaptation to warmer environment. The brl3 mutants lack thermal responsiveness and the BRL3 overexpression causes hyper-thermomorphogenesis response. BRL3 activates canonical BRI1 pathway upon elevated temperature. Further, phloem-specific expression of BRL3 completely rescues the growth adaptation defects of the brl3 mutant. This ability of BRL3 represents a previously unknown thermoresponsive mechanism specifically from phloem and uncouples the roles of BR receptors in generic growth vs adaptation to changing climate conditions.

Project description:Changing climate impacts all aspects of plant physiology, photosynthesis being particularly affected. Weather extremes result in imbalances between light capture and its assimilation, leading to photoinhibition of photosynthesis, which affects plant growth and crop yields. The Plastid Terminal Oxidase (PTOX) has been suggested as a photoprotective safety valve for photosynthesis. However, a photoprotective activity has only been observed in a small number of species and its mode of activation remains elusive. Previous attempts to induce photoprotective PTOX activity in additional species have failed. Here, we show for the first time that photoprotection by PTOX can be transferred to non-extremophile species, and that can reduce photoinhibition and ROS production under stress. Our findings provide a basis for new approaches to redesign photosynthesis using PTOX, to help crops face the challenges raised by the current climate change scenario.

Project description:Identification and sequencing of stress response transcripts in the orphan crop Fonio millet (Digitaria exilis)

Project description:Millet is a dangerous weed in Hungary. Lack of seed dormancy helps it to spread easily and be present at maize, wheat and other crop fields. Our previous report revealed the possibility that millet can also play a role as a virus reservoir. In that study we detected the presence of several viruses in millet using DAS ELISA. Because serological methods can only detect the presence of the investigated particular pathogens, we suspected that other, previously unknown viruses can also be present in this weed. To investigate this theory, we randomly sampled two locations and collected millets showing stunting, chlorosis, and striped leaves and investigated the presence of viruses using small RNA HTS as a diagnostic method. Our result confirmed the widespread presence of wheat streak mosaic virus at both locations. Moreover, barley yellow striate mosaic virus and barley virus G were also identified, which have not been described from Hungary before. As these viruses can cause severe diseases on wheat, their presence on a weed mean a potential infection risk. Our study indicates that the presence of millets on the fields needs a special control in order to prevent emergence of new diseases at crop fields.

Project description:We present a developmental transcriptome atlas of little millet. It has superior nutritional properties including high micronutrients (Fe, Zn, Ca, Mn), dietary fiber content, and low glycemic index with potential health prospective. This crop is cultivated by tribal people in the marginal areas, and it is adapted to a wide range of growing environments.

Project description:Drought is one of the main climate threats for crop plant production limitation. Climate change models predict constant global warming accompanied by strong reduction in water availability, especially for agricultural needs. Potato belongs to crop plants that are considered as sensitive to water shortage. Global estimation analyses show that drought may decrease potato yield by 18-32% in the period of 2040-2069 (Hijmans, 2003, Obidiegwu et al. 2015, Front in Plant science). Crop models predict that potato yields may reduce by ~30% as a result of water deficit in Poland (http://www.climateadaptation.eu/poland/agriculture-and-horticulture/). Genetic variability between potato cultivars has been described regarding their tolerance to drought (Soltys-Kalina et al. 2016). To diminish the effect of forecasted potato harvest losses, it is crucial to identify as many as possible potato plant strategies to withstand long drought periods during vegetative season. For this reason, we decided to analyse the expression differences in transcriptomes independently in two selected pairs of potato cultivars, Gwiazda/Oberon and Tajfun/Owacja. Cultivars in each pair are closely related to each other (having one parent in common or one grandparent in common, respectively) but differ in their sensitivity to drought conditions. In this paper, we identified at least 24 top selected genes whose expression profiles differ significantly during drought period when closely related studied cultivars are compared. Moreover, all but one of selected potato genes have their homologues in Arabidopsis plant genome. We found that A. thaliana mutants with mostly downregulated expression of seven selected homologous genes differ in their response to drought. To our knowledge, all of these genes were until now not reported as drought-related. Thus, our original approach and obtained results allowed to identify new players in plant response to drought.

Project description:The control of branch outgrowth is critical for plant fitness, stress resilience and crop yield. The Arabidopsis thaliana transcription factor BRANCHED1 (BRC1) plays a pivotal role in this process: it integrates signals that control shoot branching to inhibit axillary bud growth. Despite the remarkable activity of BRC1 as a potent growth inhibitor, the mechanisms by which it promotes and maintains bud dormancy are still largely unknown. Here we combine ChIP-seq, transcriptomic and systems biology approaches to characterize the BRC1-regulated gene network. We identify a group of BRC1 direct target genes encoding transcription factors (BTFs) that orchestrate, together with BRC1, an intricate transcriptional network enriched in ABA signalling components. The BRC1 network is enriched in feed-forward loops and feed-back loops, robust against noise and mutation, reversible in response to stimuli, and stable once established. This knowledge which will prove fundamental to adapt plant architecture and crop production to an ever-changing climate.
